Handling SubprocessModel Documents with Dynamically Invoked Processes
This document type is described in
pub.prt.CallActivityModel. When invoking a process with dynamic process behavior, it is possible to populate the
pub.prt.SubprocessModel document list to invoke two or more callable or referenced processes. For example, when the same dynamically invoked process is called twice, the parent process continues after the first child finishes and does not wait for results from the second child process.
Multiple entries in the pub.prt.SubprocessModel list with the same SubprocessModelId are supported. The return document list contains all entries from executed models where the WaitForSubprocess parameter is set to true. The order of the documents in the return document list is the same as the order in the pub.prt.SubprocessModel input list. For example:
ModelA returns Doc1
ModelB returns Doc1
SubprocessModels[0]
WaitForSubprocess - true
SubprocessModelId - ModelA
ReturnDocuments - Doc1
SubprocessInstances[0] - *
+Inputs[0]
#Type - ModelATrigger
#Document - ModelATriggerDoc1
SubprocessInstances[1] - *
+Inputs[0]
#Type - ModelATrigger
#Document - ModelATriggerDoc2
SubprocessModels[1]
WaitForSubprocess - true
SubprocessModelId - ModelB
ReturnDocuments - Doc1
SubprocessInstances[0] - *
+Inputs[0]
#Type - ModelBTrigger
#Document - ModelBTriggerDoc1
There are two instances of ModelA and one instance of ModelB invoked by the input structure above. The return document list will contain a list of Doc1 documents in the same order as shown above. Each input instance is marked with a number of asterisks that match the output document:
Doc1[0] * Doc1[1] ** Doc1[2] ***
Note that multiple entries in the pub.prt.SubprocessModel list with the same SubprocessModelId value and different WaitForSubprocess settings can make it difficult to locate the return documents. pub.prt.SubprocessModel entries that have the WaitForSubprocess parameter set to false will not have return documents in the list. For example:
ModelA returns Doc1
SubprocessModels[0]
WaitForSubprocess - false
SubprocessModelId - ModelA
ReturnDocuments - Doc 1
SubprocessInstances[0] - *
+Inputs[0]
#Type - ModelATrigger
#Document - ModelATriggerDoc1
SubprocessModels[1]
Wait For Subprocess - true
Subprocess ModelId - ModelA
ReturnDocuments - Doc1
SubprocessInstances[0] - *
+Inputs[0]
#Type - ModelATrigger
#Document - ModelATriggerDoc2
SubprocessInstances[1] - *
+Inputs[0]
#Type - ModelATrigger
#Document - ModelATriggerDoc3
There is one instance of ModelA in the first pub.prt.SubprocessModel and two instances of ModelA in the second pub.prt.SubprocessModel invoked by the input structure above. The return document list will contain a list of Doc1 documents in the same order as shown above. Each input instance is marked with a number of asterisks that match the output document:
Doc1[0] ** Doc1[1] ***
The SubprocessInstance with a single asterisk (*) has the WaitForSubprocess parameter set to false, so it is not included in the return document list.
