The SUBCISPAGE2 control allows you to place one page into another page. You may already have read the section describing the SUBPAGE control which allows to place any HTML page into an Application Designer page. The differences between the SUBCISPAGE2 and the SUBPAGE tag are:

• With SUBCISPAGE2, you embed Application Designer pages, not normal HTML pages.

• Application Designer pages are normally started using a servlet "StartCISPage" which creates an embedding frame in which the Application Designer page is placed. The SUBCISPAGE2 control automatically creates this frame, you do not have to take care of this.

• There is a defined communication channel allowing the "outside page" to interact with the "embedded page", and vice versa.

• The embedded page is automatically linked to the Application Designer session management. It runs in the same session - and typically also in the same subsession as the embedding page.

This document covers the following topics:

• Simple Example

• SUBCISPAGE2 Properties

Simple Example

The following example shows the input of an article number and its article detail data:

The detail data page is embedded into the whole (outer) page. The XML code of the outer page is:

<page model="OuterPageAdapter" pagename="Demo.html">
    <titlebar name="Page with embedded page">
    </titlebar>
    <header>
    </header>
    <pagebody takefullheight="true">
        <rowarea name="Page Name Input">
            <itr>
                <label name="Article" width="100">
                </label>
                <field valueprop="article" length="20">
                </field>
            </itr>
            <vdist height="5">
            </vdist>
            <itr>
                <hdist width="100">
                </hdist>
                <button name="Show Details" method="showDetails">
                </button>
            </itr>
            <vdist height="5">
            </vdist>
            <rowtable0>
                <itr width="100%">
                        <subcispage2 subcispageprop="innerPage" width="100%" height="350" borderwidth="1">
                        </subcispage2>
                </itr>
            </rowtable0>
            <vdist height="5">
            </vdist>
        </rowarea>
    </pagebody>
    <statusbar withdistance="false">
    </statusbar>
</page>

The SUBCISPAGE2 control references a property innerPage which is provided by the adapter class of the page. The height can be specified depending on the whole page's height or can be fixed.

The corresponding adapter source is:

// This class is a generated one.

import com.softwareag.cis.server.Adapter;
import com.softwareag.cis.server.util.SUBCISPAGEInfo;

public class SubCisPage2Adapter 
	extends Adapter
{
    // property >innerPage<
    SUBCISPAGEInfo m_innerPage = new SUBCISPAGEInfo();
    public SUBCISPAGEInfo getInnerPage() { return m_innerPage; }

    // property >article<
    String m_article;
    public void setArticle(String value) { m_article = value; }
    public String getArticle() { return m_article; }

    /** */
    public void init()
    {
        m_innerPage.showPage("ArticlePage.html");
    }
    
    /** */
    public void showDetails()
    {
        // fetch adapter of inner page
        ArticlePageAdapter ipa = (ArticlePageAdapter) findAdapter(ArticlePageAdapter.class);
        ipa.init(m_article);
        
        // trigger a refresh of the innerpage
        m_innerPage.refreshContentOfCurrentPage();
    }
}

The property innerPage is of type com.softwareag.cis.server.util.SUBCISPAGEInfo. With method SUBCISPAGEInfo.showPage, the article page is started within the subarea. This does not have to be flexible all the time - but it may be on request. (Maybe there are several versions of displaying the detail data, depending on the article type).

When choosing the Show Details button, the method showDetails() is called. It prepares the adapter of the inner page to display the detail data of the requested article. Afterwards, the method SUBCISPAGEInfo.refreshContentOfCurrentPage is called in order to reload the embedded page. Consequently, the article details are shown.

See the JavaDoc documentation of class SUBCISPAGEInfo.
