Issue with Multi-Instance and Script Tasks

unknown-user

Hi,

There seems to be an issue with multi-instance configurations and script tasks.

The following exception is thrown upon startup of the engine: ActivitiException: cvc-complex-type.2.4.d: Invalid content was found starting with element 'multiInstanceLoopCharacteristics'. No child element is expected at this point.

Might be a problem in the DTD/schema?

Adding multi-instance configurations to user tasks works without problems.

Regards,
Markus

Could you paste your relevant process xml?

Did you already try to wrap it in CDATA?

As you surmise Markus, the error cited is an XML validation error. I see it in v5.11. It looks like the Eclipse Designer is putting the 'multiInstanceLoopCharacteristics' (MILC) element in the wrong place, after the 'script' element. I moved the MILC element to first within the 'scriptTask' then successfully validated and ran.

Before, generated by the Designer:

<br><scriptTask &hellip;><br>&nbsp; <script>&hellip;</script><br>&nbsp; <multiInstanceLoopCharacteristic &hellip;/><br></scriptTask><br>

After hand edit:

<br><scriptTask &hellip;><br>&nbsp; <multiInstanceLoopCharacteristic &hellip;/><br>&nbsp; <script>&hellip;</script><br></scriptTask><br>

My XML schema knowledge is a bit rusty, so cannot say exactly why this is a problem – something to do with the 'scriptTask' inheritance relationship. The schema really should be more flexible. Regardless, it is standard BPMN2, so the problem seems to be in the Designer.

I am happy to enter a JIRA ticket with sample XML, but need a codehaus JIRA account.

Hi,

The error is now fixed for the 5.12 release of the Designer. I expect to release the 5.12 in a couple of weeks.
Thanks for raising the issue.

Best regards,
