    BPMN2 Designer Stuck loading after adding custom work item definition

    Andrew Tan Newbie

      I am trying to create a simple BPMN2 process that uses a domain specific service. However, after I add a new work item definition in drools-guvnor 5.3.1 and I attempt to create or open an existing bpmn2 process the designer gets stuck on the "Please Wait Loading" screen.

      Here is my work item definition:



      import org.drools.process.core.datatype.impl.type.ObjectDataType;
      import org.drools.process.core.datatype.impl.type.StringDataType;



          "name" : "MyTask",

          "parameters" : [

           "MyFirstParam" : new StringDataType(),

           "MySecondParam" : new StringDataType(),

           "MyThirdParam" : new ObjectDataType()


          "results" : [

              "Result" : new ObjectDataType()


          "displayName" : "My Task",

          "icon" : "",





      Looking at the server.log file of JBoss ESB I can see drools-guvnor loading the custom work item definition, and I am able to build my package in drools guvnor

      Does anyone have any ideas about why the designer is getting stuck in the "Please Wait Loading" Screen?


      I am using JBPM5.2 with drools guvnor 5.3.1 installed in JBoss SOA-P 5.3.1
