i want to approve form if “Approved” chechbox is clicked on certan form , othervise it could be defective, to control this i use delegate class(with service) here is my code:
@Service(“GetApprovedElement”)
public class GetApproved implements JavaDelegate{
Object jsonObject1=new JSONObject();
public void execute(DelegateExecution execution) throws Exception {
// TODO Auto-generated method stub
jsonObject1 =getApproved(execution.getVariable(“selectedDocuments”).toString());
execution.setVariable(“selectedDocuments”, jsonObject1);

	}
	 public Boolean getApproved(String jsonObject12) throws ParseException {
		   JSONParser jsonParser = new JSONParser();
			String jsonObject =  (String) jsonParser.parse("approved");
		    Boolean approved=Boolean.valueOf(jsonObject);
		return approved;
	   }

}

and than i use this expression for Excluive gateWay flow:
${GetApprovedElement.getApproved()==true}
But when i try to start task camunda can’t recognize approved and throws errors, what i am missing here?

Hi Sally,

it seems that there is something wrong in the method getApproved(...). It tries to parse the string “approved” as JSON object which will fail.

Best regards,
Philipp
