Persisting modified variables in scriptTask

Hello, I start a process with an output variable which is a basic HashMap. In a javascript scriptTask, I insert some values into this map as followsutput.put("result", "success");‍‍‍If I read the process variables inside an ExecutionListener at the end of the process, the result value is as expect

Are you aware of the autoStoreVariables attribute (described here http://www.activiti.org/userguide/index.html#bpmnScriptTask) ?
You have to explicitly set the value to true if you want to persist values automatically in a script task.

Best regards,

Hi Tijs,

Thanks for your answer. Yes I had tested with this attribute and found out that it works only for variables defined in the script. In my script, the variable in already defined prior to scriptTask execution. With this attribute, modifications are persisted only if I do:
<code>
<scriptTask id="success" activiti:autoStoreVariables="true" scriptFormat="javascript">
output.put("result", "success");
output = output;
</code>

Could it be that modifications should be detected and are not ? Please let me know if you would like a testcase to exhibit this behaviour.

Regards,

Tom

Hi Tom,

Good point, I think Activiti isn't able to see the changes to the HashMap. For now I guess we have to go for the explicit call.
Yes, you can create a JIRA for this with a test showing the issue.

Best regards,
