How to get extensionElements variable value if we have only taskId through API

[krishnapatra]

I'm using activiti with spring rest api. User will be having option to select any of its listed tasks and ask for the values of extensionElements. To do so, I'm making a rest call with taskid.
Is there a way to fetch value of extensionElements through taskId.

Below is my workflow:
         <userTask id="writeReportTask" name="Write monthly financial report" activiti:assignee="${assignee}" activitiwner="${owner}">
            <extensionElements>
                <activiti:field name="clientName" stringValue="${clientName}" />
                <activiti:field name="companyName" stringValue="${companyName}" />
            </extensionElements>
          </userTask>

         <userTask id="financeReportTask" name="review monthly financial report" activiti:assignee="${assignee}" activitiwner="${owner}">
            <extensionElements>
                <activiti:field name="clientName" stringValue="${clientName}" />
                <activiti:field name="companyName" stringValue="${companyName}" />
            </extensionElements>
          </userTask>

Hi,

Extension elements can be read from the BpmnModel object. So you could fetch the process definition XML and use the BpmnXMLConverter to transform it into a BpmnModel instance and then get the flow element with the task id. You can also fetch the BpmnModel as JSON with a REST service call http://activiti.org/userguide/index.html#_get_a_process_definition_bpmn_model.

Best regards,
