Activiti Modeler - custom components

racadent — Thu, 10 Jan 2013 17:11:38 GMT

Is it possible to have combobox with predifined variables in the Service Task component instead of Complex type (list of values) for Class field (Field extension) in the Activiti Modeler 5.11. What I want to do is to create custom component with predefined java class that implements the service task

Sure, that's perfectly possible.

Do you have any example, demo that can be helpful, because I already try it on my way but without success?

No there's no example yet. The best way is to look at the other attribute definitions at the moment.

The problem is when I replace above json "Complex type" code with "Choice":

{
      "id" : "servicetaskfields",
      "type" : "Choice",
      "title" : "Class fields",
      "value" : "action",
      "description" : "Field extensions",
      "popular" : true,
      "items" : [ {
        "id" : "v1",
        "title" : "Value1",
        "value" : "0"
      }, {
        "id" : "v2",
        "title" : "Value2",
        "value" : "1",
      } ]
    }

I get regular combo box with values in the properties panel and after I select value and generate bpmn20.xml I get:

    <serviceTask id="sid-682459E4-9AE5-49A1-8EBB-CE0584676771" name="TestService" activiti:class="de.pickert.bpmn.services.ActionService"></serviceTask>

Instead of:

     <serviceTask id="sid-682459E4-9AE5-49A1-8EBB-CE0584676771" name="TestService" activiti:class="de.pickert.bpmn.services.ActionService">
      <extensionElements>
        <activiti:field name="action" stringValue="0"></activiti:field>
      </extensionElements>
    </serviceTask>

which I get with Complex type. Am I missing something?

That's because the transformation from the field extensions attribute expects a complex type and not a choice.
For this to work you would have to implement the right transformation logic in the activiti-json-converter project.
