The Natural example library SYSEXNJX
provides an example of
a workplace built on base of the Application Designer framework. The example can be executed
with the following URL:
http://<host>:<port>/cisnatural/servlet/StartCISPage?PAGEURL=/njxdemos/wpdynworkplace.html
For information on the Natural versions with which this example is provided, see the section Support for Special Features.
The workplace framework bases on the multi frame page management described in the previous sections. It offers the following:
flexible arrangement of frames,
dynamic loading of available functions,
possibility to change the environment at runtime via specific controls,
execution of multiple tasks between which the user can switch ("multi document interface").
This document covers the following topics:
An Application Designer workplace is a certain arrangement of frames in a multi frame page. Some of the frames have predefined tasks. Have a look at the example workplace in which you can already see the most important frames:
The "Functions" frame contains the available functions that can be chosen and invoked by the user. The "Content" frame contains the page or page sequence that is opened if a function is selected. The "Active Functions" frame shows the functions that were opened by the user and allows the user to navigate between the active functions.
Have a look at the XML layout definitions for this workplace; it defines how the frames are arranged (../njx<nn>.ear/cisnatural.war/njxdemos/xml/wpdynworkplace.xml):
<?xml version="1.0" encoding="UTF-8"?> <mfpage separation="rows" sizing="20,*"> <mfwpactivefunctions resizable="false" withborder="false" scrolling="false" framestyle="border: 0px solid #000000"> </mfwpactivefunctions> <mfframeset target="ZZZ" separation="cols" sizing="265,*"> <mfframeset target="LEFTPART" separation="rows" sizing="*,400" border="true" framesetstyle="border: 1px solid #808080"> <mfwpfunctions bootstrapinfourl="/njxdemos/xml/wpdynbootstrapinfo.xml" serversidescrolling="false" framestyle="border: 1 solid #808080;"> </mfwpfunctions> <mfhtmlframe target="NEWS" url="../njxdemos/html/wpdynhowto.html" resizable="true" withborder="false" scrolling="true" framestyle="border: 1px solid #808080"> </mfhtmlframe> </mfframeset> <mfwpcontent resizable="true" withborder="true" scrolling="false" framestyle="border: 1 solid #808080;"> </mfwpcontent> </mfframeset> </mfpage>
You see that there are three special frame controls that are used internally: MFWPFUNCTIONS, MFWPACTIVEFUNCTIONS and MFWPCONTENT. In addition, there is one HTML page arranged below the MFWPFUNCTIONS control.
Let us take a closer look at each of the three workplace frame controls.
This is the frame to hold the available functions to be selected by the user. The control has the following properties:
Basic | |||
bootstrapclass |
Name of the class that is responsible for passing the initial workplace configuration. The class must support interface "IMFWorkplace2" and must support a constructor without parameters. When being displayed the workplace creates an instance of this class and asks for an object that represents the workplace setup. Have a look into the javadoc-documentation for interface "IMFWorkplace2" for more information. |
Optional | |
bootstrapinfourl |
URL to an .xml file that holds the initial workplace configuration. Do not use BOOTSTRAPINFOURL and BOOSTRAPCLASS at the same time! Use /project/directory/doc.xml as syntax, e.g. /HTMLBasedGUI/workplace/bootstrapworkplaceinfo.xml. |
Optional | |

The
MFWPFUNCTIONS frame can be filled initially by using the
bootstrapinfourl
property. This property expects
an URL to an XML file that represents the initial
workplace setup (for example, ../njx<nn>.ear/cisnatural.war/njxdemos/xml/wpdynworkplace.xml).
Have a look at the corresponding XML file:
<mfwpbootstrapinfo defaultcontentpage="/HTMLBasedGUI/empty.html" workplacestylesheet="../cis/styles/CIS_DEFAULT.css" synchtabnavigation="true" showdustbin="true" withtakeouttopopup="false" withcloseallwindowsicon="false" mfworkplaceeventlistener="com.softwareag.cis.workplace.MFDefaultEventListener" targetnameofresizableleftpart="AVAILABLEACTIVITIES" translationproject="tshmfp" translationreference="mfworkplace"> <mfwptopic name="System" treeclass="WORKPLACETOPIC1ClientTree"> <mfwpfolder name="System" draginfo="System" opened="true"> <mfwpopencispage name="Login" activityurl="/cisnatural/NatLogon.html&xciParameters.natsession=Workplace &xciParameters.natparam=stack%3D%28LOGON+SYSEXNJX%3BWPLGIN-P%29" onlyoneinstance="true" followpageswitches="true"> </mfwpopencispage> </mfwpfolder> </mfwptopic> <mfwptopic name="Maintain Workplace" treeclass="WORKPLACETOPIC1ClientTree"> <mfwpopencispage name="Maintain Function Tree" activityurl="/cisnatural/NatLogon.html&xciParameters.natsession=Workplace &xciParameters.natparam=stack%3D%28LOGON+SYSEXNJX%3BWPFUNC-P%29" onlyoneinstance="true" followpageswitches="true"> </mfwpopencispage> <mfwpopencispage name="Maintain Content Pages" activityurl="/cisnatural/NatLogon.html&xciParameters.natsession=Workplace &xciParameters.natparam=stack%3D%28LOGON+SYSEXNJX%3BWPCONT-P%29" onlyoneinstance="true" followpageswitches="true"> </mfwpopencispage> </mfwptopic> </mfwpbootstrapinfo>
Note:
To make sure that you are using a proper
bootstrapinfo.xml file, use the XML Schema
editor.xsd (and all corresponding XSD files) to validate
your XML file (for example, in XMLSpy).
Overview of the bootstrapinfo hierarchy:
<mfwpbootstrapinfo> // root tag <mfwptopic> // new topic <mfwpfolder> // MFWorkplaceTreeNodeFolder <mfwpopencispage> // MFWorkplaceTreeNodeCISPage <mfwpopencispopup> // MFWorkplaceTreeNodeCISPopup <mfwpopencistarget> // MFWorkplaceTreeNodeCISTarget <mfwpopenhtmlpage> // MFWorkplaceTreeNodeHTMLPage <mfwpopenhtmlpopup> // MFWorkplaceTreeNodeHTMLPopup <mfwpopenhtmltarget> // MFWorkplaceTreeNodeHTMLTarget
Each of the sublevel tags can contain all sublevel tags as subnodes, including itself.
The following topics are covered below:
Basic | |||
defaultcontentpage |
The workplace consists out of several frames, one of it the content frame. If there is no active activity in the workplace then the defaultContentPage is displayed inside the content frame. You can use this in two ways: (1) Either create one "background page" which always is shown in an "empty" workplace. (2) Or create one "background page" which the workplace opens by default. E.g. you want in a start-workplace to first present to the user a logon page. EXAMPLE: "/HTMLBasedGUI/empty.html" |
Optional | |
workplacestylesheet |
The stlye sheet which is used for the left and top frame of the workplace. If no style sheet is specified then the workplace adapts to the standard style sheet which is kept in the CISsession context. You typically want to use one fix child for a workplace - because the workplace is typically embedded in some other frames arranging some graphics/etc. around, and you do not want the workplace colour's to change independent from this. EXAMPLE: "/cis/styles/XYZ_STLYE.css" |
Optional |
background-color: #FF0000 color: #0000FF font-weight: bold |
translationproject |
Name of the project where the actual used multilanguage file is located. e.g. cisdemos |
Optional | |

Name of the multilanguage .csv file. e.g. test (if the file test.csv should be used)
|
Optional | |
comment |
Comment without any effect on rendering and behaviour. The comment is shown in the layout editor's tree view. |
Optional | |
Appearance | |||
mfworkplaceeventlistener |
Use this interface to react on workplace events. (1) Create an implementation of this interface (2) Use method (3) Use method Step two and three are typically done within the "bootstrap info provider"-class A CISworkplace is a certain arrangement of frames in a multi frame page. The "functions"-frame (MFWPFUNCTIONS) holds the available functions to be selected by the user (click with the left mouse Button). In addition you can provide for right mouse button menu or drag and drop within the function tree. With that you may allow users to add/remove/shift menu items (personalization). |
Optional | |
targetnameofresizableleftpart |
The workplace may contain a favourite list. At the bottom of the favourite list there are some items by which you can influence the size of the corresponding left part of the workplace. The name of the target frame to be resized is passed with this method. |
Optional | |
View | |||
showdustbin |
Flag that indicates wether the dustbin (have a look at the DEMO WORKPLACE) is shown or not. Boolean value, default is false. |
Optional |
true false |
synchtabnavigation |
Set flag that decides if the tree "on the left" is synchronized with the tab navigation "on the top". If the user selects an opened activity in the tab strip then the corresponsding tree node and topic is shown as consequence. Pay attention: the base of the synchronization is the naming of nodes. There is currently no naming concept beyond (that e.g. assigns ids to nodes). Make sure, your tree nodes are set in a way that each one holds a unique name. Use the tabText (setTabText) in order to make nodes unique! true ==> synchronization is done; false ==> synchronization is not done; default is false. |
Optional |
true false |

When the user selects functions in the MFWPFUNCTIONS frame, then pages are opened in the content frame, or as popups or in a named target frame.
The workplace offers a "multi document interface" - i.e. you can work in parallel in several activities and you can switch between these activities. This structure is reflected in the server-side session structure. The section Details on Session Management in the Special Development Topics (which is part of the Application Designer documentation) explains this in a detailed way. However, some information is given below.
The session management of Application Designer knows sessions (typically representing a browser instance) and subsessions (reflecting a user activity with a defined life cycle). A session contains one or more subsessions. Inside one subsession, the adapter object are kept which are required by a page or a page sequence. Subsessions are isolated from one another.
The workplace proceeds in the following way:
Every activity that is started inside the content is represented by a subsession of its own. If you have opened five Application Designer pages via the function tree inside the content area of the workplace, then there are five subsessions on the server side. If the user navigates between the activities (e.g. via the MFWPACTIVEFUNCTIONS frame), then from session point of view the user navigated between subsessions.
The workplace itself also occupies one subsession. If Application Designer pages are opened in a popup or in a named target, then these pages are living inside the subsession of the workplace.
When programming content pages, you do not notice the session management: every page that you design and test in the Layout Painter behaves in the same way in the workplace. Due to the separation into subsessions, you are not aware of "neighboring" subsessions.
Internally, the workplace is started when the workplace frameset page is loaded. So far you got to know the framework to set up the workplace by providing a MFWPBOOTSTRAPINFO file.
But you can also dynamically manipulate the workplace. There are two typical usages:
You can exchange all workplace definitions dynamically. Maybe you offer the user a "reduced" workplace just allowing the user to log on at the beginning. Afterwards, the "real" workplace for the user is built up - containing all functions available for the user.
You can manipulate workplace definitions in an existing workplace. For example, you modify the title of an activity that is shown in the MFWPACTIVEFUNCTIONS area. Or you want to add certain nodes to an existing tree.
For this purpose, there is a set of controls containing the workplace functions that you can use from your application:
