ibatis issue with simple process definition containing asynchronous service task

[ahi...@unitybox.de]

Hi guys (& ladies?),

we have a simple process containing start event, service task (async) + end event.
We start it embedding the process engine (within a JUnit - Test) - and get the following ibatis error:

Nov 07, 2013 5:16:01 PM org.camunda.bpm.engine.impl.interceptor.CommandContext close
SEVERE: Error while closing command context
org.apache.ibatis.exceptions.PersistenceException:

Cause: org.apache.ibatis.reflection.ReflectionException: Illegal overloaded getter method with ambiguous type for property scope in class class org.camunda.bpm.engine.impl.persistence.entity.ExecutionEntity.

Hi Peter,

camunda BPM 7.0 Final depends on mybatis version 3.1.1. In this version, you should not get the exception.

I opened a JIRA here: https://app.camunda.com/jira/browse/CAM-1481

Cheers,

Daniel Meyer

[Daniel Meyer]

I pushed a fix to master. Could you check with camunda BPM 7.1.0-SNAPSHOT whether the issue persists?

[Grobarcik Peter]

Das war es! Ich bedanke mich herzlich für die schnelle Hilfe!

Hi Guys,

Sorry to bump the post. We've been working on the integration of Camunda in our application, which depends on mybatis 3.2.3, and still run into the same error.

[Roman Smirnov]

Hi,

which version of camunda BPM are you using? The fix is available since 7.1.0-alpha1.

Cheers,

Roman

[Bart Brandhoff]

Initially we were using 7.0.0-Final, but we tried switching to the alpha version and still get the error.

Do you get the same exception?

The issue has been fixed and mybatis 3.2.3 will be fully supported in camunda BPM 7.2.0
