Hi All,
I marked a previous question as answered - but it didn't really solve the issue:
https://community.jboss.org/thread/204089?tstart=0
https://community.jboss.org/thread/204089?tstart=0
The only variables that are being returned are those that are passed to the process when
it is started. However the process definition file has variables defined which do not
show up in the list used by the method in the previous post.
Is there a way to get the variables and their values that are defined in the bpmn2 file
that is used to start a process instance in addition to the ones passed in the
startProcess call?
Regards,
Jim

you mean that you have process variables that are set but are not returned from this
command? Or you mean that the variables are defined but not set? As this command will
return only those variables that are currently set (in other words not null)
HTH
P.S.
thanks for starting new thread for this, makes it much easier to follow.

Hi Maciej,
So from what you are saying if the variable has not been set and thus has a null it value,
it will not be returned. If an "approved" variable is created as a Boolean with
a value false when defining it in the designer shouldn't that then be "set"
and thus show up in the variable list? It doesn't. I looked at the xml and don't
see it actually getting a false value being set anywhere:
<itemDefinition id="_approvedItem" structureRef="Boolean" />
<itemDefinition id="_7DF7FB64-0962-4846-8C2A-17B11D06C7E4-approvedItem"
structureRef="Boolean" />
<itemDefinition id="_545A22D5-CA8A-49DD-B539-9497C0A6D6ED-approvedItem"
structureRef="Boolean" />
<process processType="Private" isExecutable="true"
id="test.BasicReview" name="BasicReview"
tns:packageName="test" >
<!-- process variables -->
<property id="approved" itemSubjectRef="_approvedItem"/>
There are no other references in the file.
Regards,
Jim

defining variable in process with a type does not mean that the engine will instantiate
it with default value of that type when starting process. It needs to be explicitly given
to the process either with start parameters or by setting variable via processInstance API
or by mapping external service output into process variable.
