Create of BPMN XML failed...

[joselouro]

Hi,

I've been doing some tests to create a small PoC.
I've modelled a small process on Eclipse (Activiti Designer) and it was exported from Eclipse and imported on Explorer.

While trying to deploy it, I got "Create of BPMN XML failed. Error parsing XML"…

Anyone can give me a clue about what is wrong ?

Thanks…

Here is the code:

Hi José.

I created small jUnit test for your issue. Maven project can be downloaded from here.
Issues are
1. "code" tag at the end of your file - I think it was done because of copying/formatting
2. line 38 in your process definition contains only one =, there should be two ==.
<code>
                <completionCondition>${assignee == ""}</completionCondition>
</code>
Changed process definition is here

Hi Martin,

Thank you very much for your help…
I'll correct it, and keep testing…

Best regards,

You should see something in your server logging that gives you an indication of the error

Hi,

I had the same problem today. I can not export my bpmn model to an xml file.

In my server's terminal, these are the first lines of the error message:
ERROR org.activiti.editor.ui.EditorProcessDefinitionDetailPanel - failed to export model to BPMN XML
java.lang.NullPointerException
    at org.activiti.editor.language.json.converter.BpmnJsonConverter.filterAllEdges

I attached the file localhost_access.log which is the only file showing an error (ctrl +f), all others files are empty or not showing any error.

Can you give me a clue about this problem ?

Thank you

The exact line number of the filterAllEdges method should be included as well.
I'm expecting a sequence flow that's not correctly attached to the source or target element.

Best regards,
