Validation in Expressions Bug

rodolfobarbeiro — Fri, 03 Aug 2012 14:53:47 GMT

Hi,BPMN processes with empty expressions are not deployed and no error occurs. The Activiti indicates that it has successfully deployed, but this does not happen really.I'm using Activiti 5.9.Example:…<exclusiveGateway id="invokeOsgiServiceCheckResult" name="Exclusive Gateway" />

Validated this, and indeed, the deployment doesn't fail and the process is not deployed.
https://jira.codehaus.org/browse/ACT-1391

An error is logged, but no exception is thrown:
