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
