I have business process described in bpmn file. It has scriptTasks that use some project types.

<itemDefinition id="_stepItem" structureRef="project.model.Step" />

<itemDefinition id="_actionsItem" structureRef="java.util.Map" />

<process processType="Private" isExecutable="true" id="com.sample.id" name="EXAMPLE" tns:packageName="defaultPackage" tns:version="1" >

<!-- process variables -->

    <property id="step" itemSubjectRef="_stepItem"/>

    <property id="actions" itemSubjectRef="_actionsItem"/>

...

<scriptTask id="_2" name="1FakedStepAction" scriptFormat="http://www.java.com/java" >

      <script>          

               try { 

                     ((StepAction)(actions.get("1StepAction"))).executeStepAction((Step)step);  }

               catch (Exception e) {

                         System.out.println("Exception  1StepAction: "+e);

               }

         </script>

</scriptTask>

...

In Java code I put

Map<String, Object> params = new HashMap<String, Object>();

params.put("step", <some real instance of Step>);

params.put("actions", <some actions map like 1StepAction -> real instance of StepAction>);

ksession.startProcess("com.sample.id", params)

It works fine when I put such file in class path and spring configuration uploads it from this file. I put it to Guvnor. And application successfully load such process from it and run.

But when I try to build package in Guvnor with such process it complains :

Unable to generate action invoker. project.model.Step cannot be resolved to a type

Process Compilation error project.model.Step cannot be resolved to a type

StepActioncannot be resolved to a type

So, how Guvnor can access to my types deployed in my project? Is it possible?
