Hi,

I've made a new model in Activiti Designer and when I try to export (or deploy) it it fails with "Create of BPML XML failed   null". From the tomcat log I can see the following output:
03:09:10,143 [http-nio-8084-exec-10] ERROR org.activiti.editor.ui.EditorProcessDefinitionDetailPanel - failed to export model to BPMN XML

but it's hard for me (especially as a newie to Activiti) to know exactly what I've done wrong in my model. Probably something missing, but don't know what. How can I narrow down this issue, and how can I export the model so I'm not loosing it (since I'm currently only using the in memory database, and assume it will be gone as soon as I stop my tomcat server).

Best regards

When I delete all connections between the user tasks it is possible to export it to XML, so it must be related to some of the connections. It seems that if I tweak the line (if it's not a strict line), then it fails. Any clue?

martin_grofcik · ‎06-30-2014

Hi,

Could you create jUnit test with process definition deploy?

Regards
Martin

viggo_navarsete · ‎06-30-2014

Hi Martin. Sure I can, but since I'm new to Activiti, I don't know how to get the process definition out of Activiti Explorer. Isn't it by exporting it to XML and then import it in Java as a JUnit test? As soon as you give me some hints, I'll provide you whatever you need, JUnit test included

martin_grofcik · ‎06-30-2014

Hi,

How to write jUnit test:

Isn't it by exporting it to XML

yes.

You have to deploy this process definition (by annotation or code) into the process engine in the jUni test.

Martin

Hi Martin,

great to see the template project, and will of course use it to provide as much information as possible. BUT, in my case, I'm not able to get hold of a XML file containing the process definition since it's the export of the process definition which fails

What do I do then?

martin_grofcik · ‎07-01-2014

🙂 Really good point 🙂
I do not know where modeler stores its models.

Regards
Martin

viggo_navarsete · ‎07-01-2014

Martin, how do I get in contact with either Nicolas Peters, Stefan Krumnow or Linton Baddeley, who seem to be developers of Activiti Modeler (http://activiti.org/team.html).

jbarrez · ‎07-07-2014

They are not the developers of the modeler (Linton for example is a UX guy of Alfresco)

The models are stored in ACT_RE_MODEL

viggo_navarsete · ‎07-07-2014

Thanks a lot

Is the model blobed into the ACT_RE_MODEL? What's the easiest way to get it out of the table?
