Complex Data Object with SubProcess Invocation in jBPM 6.4.0

[abhisheksit2004]

Hello Experts,

I am having a complex data object say exampleDO with 2 fields(id, name) in Process-A with values - '1', 'test'.

I need to invoke another sync process-B for which I am using Re-usable subprocess i.e. B and did input 'in' of type 'exampleDO 'and output 'out' of type 'exampleDO' mapping .

Problem I am facing is that data initiated in Process-A with exampleDO is set to NULL while invoking Process-B. In the sense, Process-B have dataobject of type 'exampleDO' with NULL values.

Not sure, why the data object value is getting NULL.

I am using jBPM 6.4.0.

Please suggest ASAP.

Regards,

Abhishek

Hello Folks,

Any suggestions.

I have tried all ways but DO in Process-A is not getting passed in DO for Process-B.

This is really annoyed that this simple I/O, O/P dataobject mapping from Reusable subprocess is not working.

Abhishek

Can you attach sample process definition to check Data mapping ? Ideally it should work, have you tried with pre-defined(String,int..etc) data types?

[abhisheksit2004]

I have checked with primitive data types and it is working.

But it doesn't seem to be working with data objects.

I am attaching the project for reference.

Please suggest.

You are performing wrong "Assignment" in reusable process node, because of this you observe null value in child process. Take a look at attached project.

Thanks for response.

I updated the mapping and assigned to DO using script task but still I am facing issues where NULL values are coming ! !.

Please check the attached project and suggest.

Hi,

I am not able to understand that why human task UI is not displaying the data object values when I have a script task just before that and able to print the data object.

testBO=(bewell_org.bewell_rep.testDO)kcontext.getVariable("sin");

System.out.println(testBO.getCustomerId());

Please suggest.

Hello,

I am able to get data object in Subprocess from Parent process along with all values.

Now, there is another problem.

I am updating the data object in subprocess and requires to update data object in Parent process too.

I followed the same steps as below butting getting NULL in 'Final' script task of Parent Process.

testBO=(bewell_org.bewell_rep.testDO)kcontext.getVariable("sout");

System.out.println(testBO.getCustomerId());

sout: Output variable from Subprocess properties. !

Attaching the project for reference.

Please suggest.

Hi,

Please suggest as I am not getting updated data object in Parent process.

Hi,

I never tries using sin/sout in variable mapping, in place of sin/sout can you try using variable names(testBO) ?
