Are you using the latest version of the Designer? Only the latest version (0.7) generates the correct diagram interchange element required to display the image.

Hi,

Are you using the Activiti Designer (Eclipse plugin) or did you implement the BPMN XML yourself?

Best regards,

I tried it yesterday, and there seems indeed to be a problem with diagram generation.
The diagram png is in the databasem but the name is incorrect it seems.

I'll look into it.

Joram,

this might be related to this issue? http://jira.codehaus.org/browse/ACT-529

I will be looking at whether we can generate an image as the API expects. Would it be used in that case?

Tiese: jup, indeed. Now there is in the database something like /yourprocess.diagram.png (or something alike)

The reference in the userguide is 100% correct. So if your process resides in /myprocess.bpmn20.xml, your image should be /myprocess.png

(I added the '/' because the designer seems to add it automatically)

What do you mean that Designer adds a slash to the filename? That would be an invalid filename and could not work. In my workspace it creates the file as you described, but to leading slash.

I have resolved the issue on the Designer end, see here: http://jira.codehaus.org/browse/ACT-529

The image is now a PNG image and follows the second mentioned convention (for single process) as mentioned in the userguide here: http://www.activiti.org/userguide/index.html#providingProcessDiagram

This is what I found.

I have an XML file XXXXX.bpmn20.xml created using Activiti Designer.
Deployed this XML file alone using the repositoryService as seen in the User Guide.
All is well.

Pulled back the same process into activiti-explorer's (deployed on a glassfish) web page, process shows but not the diagram.

When I switched to Tomcat, the diagram shows up.

Is there something I am missing.

Thanks.

Hi,

Are you running this Glassfish app on a headless server?
There's a JIRA issue about this, that's resolved in the trunk.
Headless servers don't generate a diagram image in 5.9 due to a bug.
