Description
Assuming you have a BPMN like this:
<definitions id="Definition" ...> <itemDefinition id="_myMapItem" structureRef="java.util.Map" /> <process processType="Private" isExecutable="true" id="com.sample.bpmn.hello" name="Hello World" > <property id="myMap" itemSubjectRef="_myMapItem"/> ... <userTask id="_4" name="Task 1" > ... <dataInputAssociation> <sourceRef>myMap.var1</sourceRef> <targetRef>_4_myMapVar1Input</targetRef> </dataInputAssociation> ... </userTask>
jBPM5 runtime (BRMS 5.3.1) can run the process and 'myMap.var1' is interpreted as 'myMap.get("var1");' though it logs a schema error on parsing:
(null: 101, 15): cvc-id.1: There is no ID/IDREF binding for IDREF 'myMap.var1'.
Note: Result mapping to 'myMap.var1' doesn't work (Message : "Could not find variable scope for variable myMap.var1").
But Process Designer throws an Exception and fails to import when you import such a BPMN.

This JIRA requests Designer to accept such a BPMN. There can be some variants which are usually acceptable as MVEL expression:
- Getter: e.g. 'person.name' which represents person.getName()
- More nested case: e.g. 'myMap.person.name' which represents myMap.get("person").getName();
