version_ in ACT_RE_PROCDEF

[micharg]

Hello,

out of the blue in table ACT_RE_PROCDEF I have two rows for my workflow process; one with version_=1
and one with version_=2. When is version_ incremented?

Thank you

This is when you deploy a new version of your process definition.

Thank you for your answer. The strange thing was that I didn't change the bpmn (http://www.activiti.org/userguide/#versioningOfProcessDefinitions). I just redeployed
the application. In order the Activiti Engine to detect if the bpmn has changed does
it hash the file? Does it compare the creation dates? Or does it follow another algorithm?

Thank you again,
Mike

Do you have your process xml in your process engine config?
That would explain the duplicates, unless 'enableDuplicateFiltering' is set to true.

It compares the strings of the xml as-is.

Thank you for your answer.

Hi, I'm completely new at using Activiti and running into the same issue of creating a new version of the process upon every deployment event though nothing has changed. Could you please explain it in detail… Thanks!

That's one possibility yes, which version of Activiti are you using?

Best regards,

In my case the process file contents was the same BUT its path was different  between two deployments (I deployed the war on a different computer).
