Create of BPML XML failed null

[viggo_navarsete]

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

Indeed it is  - the easiest is to fetch it and pour it into a Java String using UTF-8 encoding of the bytes
