Defining variable on ProcessDefinition (Bpmn)

Hi,I add end listeners to the end events in a process. I've some process definitions that I can ignore the listener with respect to the some variable in process instance. I set this variable according to the key of the process definition. Let's say, if the key ends with "-XYZ", end event listener sh

The only current 'solution' is a listener (script) that adds that variable to the process

Thank you. Does BPMN support a feature like this? Maybe I can work on a task like this?

BPMN 2.0 does have something like that (called 'properties'), however in our opinion the xml is kind of messy and way too complex.

But something simple like

<code>
<activiti:variable name="something" value="theValue" />
</code>

With a converter for string -> different types might do the trick and isn't that hard to write.

Hi Joram, thanks for the tip.
I've seen something I can do like :
<code><property activiti:elementVariable=""/></code>
inside the <code><process></process></code> tags. Do you know what are they? May I use them something like this?

Yes I remember that in some old code, but I don't believe it works (and it is not tested for sure).

But yeah, something like that would work. But of course, with custom mappers to go from xml string value to any other type.

Hi guys,

Joram, I am very interested in knowing more about this :
<code><activiti:variable name="something" value="theValue" /></code>

How do I tell the validation step to accept this kind of variable ?
so far it returns: ActivitiException: Error parsing XML

Can this variable be stored in one of the activiti tables ?
I'm using Activiti 5.14.

Thanks a lot,

Yohann: 5.15 added a new feature which pretty much does this, see http://activiti.org/userguide/index.html#dataobjects

Thanks Joram.
Congrats for the release by the way too.
Looks like there are plenty of useful stuff that are added (Customized queries my MyBatis …).

Thank you. I think it will be sufficient for us.
