Newbie again - show diagram....

[jchildress]

I've deployed a simple process and it "works" fine, but when I click the "Show Diagram" button I get the following….

I've attached my bpmn file…

I guess my basic question is if anyone has the "auto" diagram working for them?

thanks,

When I deploy your process with probe, and click on 'show diagram' in Explorer, it just works.

(note I tested on 5.3)

[jchildress]

I'm on 5.2 

can I get/try 5.3?

thanks,

John

Ok, I was looking for some help on loading forms and I came across a post that mentioned the deployment table "ACT_GE_RESOURCE_".  I don't have that table, but found "ACT_GE_BYTEARRAY" which seemed similar.  Anyway that table had a reference to a ".png" file for my process that I didn't "upload/insert".  Once I deleted that entry the diagram was created/generated as advertised.

I'm using 5.2 on Windows with MS SQL Server.

Any idea why that ".png" file entry was inserted?

thanks,

John

@jchildress: we're currently testing the 5.3. If all goes well, it is online tomorrow.
But it sure is strange, because not much has changed in that area from 5.2-> 5.3

@John: If your process has Diagram Interchange information (eg coming from Modeler/Designer), then a png will be automatically created when deploying the process. That will probably be the png that you are seeing.

[jchildress]

So dumb question…  I need the Diagram Interchange information right?  If the diagram is to be auto-generated…

Can I control how the name of the png file that is generated is created?  That way the deployment process would/could name the file "correctly"?

@John: Yes, your process needs diagram interchange information if you want the diagram to be auto-rendered.
The png name will also be automatically determined based on your process definition, so there is no need to change it.
