BPMN2 Import Probleme

non — Mon, 27 May 2013 08:59:38 GMT

Hi.Got problems importing existing BPMN2 files:E.g. I created a very simple flow in Signavio's online modeller and there seems to be no way to open/import it in activiti-explorer. Lastly I compared the XML with the XML of an importable BPMN2 file and noticed a difference for the "isExecutable" attri

* You should see a warning log message in the console passing by. Some people don't want to execute processes, just document them.

* The import should be able to take the process as it is. Any chance you can upload this process somehow?

* Depends on what you call an import. An import into Explorer? As such, it would be very easy to write simple Java script that takes these process xml files and deploys it to the database that the Activiti (Explorer) is using.

* Does Yaoqiang allow to transform these processes?

Try to import http://www.omg.org/spec/BPMN/20100602/2010-06-03/Models%20&%20Diagrams/Process.bpmn
(Renaming to .bpmn20.xml makes no difference / validates against xsd / Loading Process.bpmn in yao and saving it as "for activiti .bpmn20.xml" makes no difference. same error.)

You get:

Setting VAADIN to debug mode does not produce more information here.

If I export the "Demo Process" and re-import it, no error occurs.

Regards.

Setting isExecutable="true" did the job here.

This is what I meant with "What is exactly expected by activiti-explorer BPMN2 import?".
Also a better error message at GUI level would help. It just says "Import failed. Make sure that the file contains valid BPMN".

Result till here: Document should be schema valid and process must have isExecutable="true".

2 simple pools, can not be imported:

https://gist.github.com/anonymous/5698141

"Import failed. Make sure that the file contains valid BPMN"

What is missing here?

I found that I can only have one pool.

Meaningful error message would help to avoid confusions.

Do you mean import in Explorer or import in Designer?
