Hi,

if I place the following into my plugin.xml

      
<modelExtension
        id="bpsim.modelExtension.Process"
        name="Bpsim Process Extension"
        runtimeId="org.example.bpmn2.modeler.bpsim.runtime"
        type="Process">
      
      <property name="extensionValues">
      	<value>
<property name="bPSimData">
		         <value>
		            <property
                    name="scenario">
                 <value>
                    <property
                          name="author">
                    </property>
      	</value>
      </property>
      	</value>
      </property>
      	</value>
      </property>

	</modelExtension>


all seems to work, but I don't get the "author extension".

If I try and valorize the author property, i.e.

      
<modelExtension
        id="bpsim.modelExtension.Process"
        name="Bpsim Process Extension"
        runtimeId="org.example.bpmn2.modeler.bpsim.runtime"
        type="Process">
      
      <property name="extensionValues">
      	<value>
<property name="bPSimData">
		         <value>
		            <property
                    name="scenario">
                 <value>
                    <property
                          name="author" value="foo">
                    </property>
      	</value>
      </property>
      	</value>
      </property>
      	</value>
      </property>

	</modelExtension>

I get the following error:

Pelase note that "author" is declared as a String (not EString) in ecore file (referring to xmltypes), but strangely, if I change that to EString, I obtain the same behaviour.

Please help, I am stuck from almost a day.

Hi Francesco,

Sorry for the late reply, I've been rather busy lately Wink

I'm afraid you'll have to write your own Property Tab class to handle these extension values. In fact, it looks like a lot of what you're trying to do is already being done in the jbpm plugin. Please have a look at org.eclipse.bpmn2.modeler.runtime.jboss.jbpm5.property.SimulationPropertySection and org.eclipse.bpmn2.modeler.runtime.jboss.jbpm5.property.SimulationDetailComposite. The PropertySection class is referenced in the <propertyTab> extension of the jbpm plugin.xml.

HTH,
Bob
