Toshiya Kobayashi <tkobayas> made a comment on jira JBPM-4102

Attaching sample bpmn.

- I removed 
targetNamespace="http://www.jboss.org/drools" for Designer to be able to accept.
- I removed 'Result Mappings' which causes another error.

Comment 2 Kris Verlaenen 2013-10-11 01:28:05 UTC

sourceRef of a data association should be a valid IDREF, so strictly speaking, it can't be something like <sourceRef>myMap.var1</sourceRef>.  A transformation element (which is an expression inside the data association) should be used to store the expression.

So when using BPMN2 (both Designer and Eclipse), currently the user cannot set expressions as source for data associations.  As alternative, scripts should be used to set a variable with the right value and then use a simple data association to map that variable to the data input.

We will have to consider adding support for transformation expressions in the future.

Lowering priority based on devel_ack-

we already have support for transformation from the engine point of view. I talked to both Tihomir and Bob regarding support in the tooling though not sure it has been developed. I am quite sure eclipse modeler can show it when defined in source xml.
