NullPointerException during programmatically generation of diagram Images [message #1718384]

Hello,

i am trying to generate Images of programmatically generated diagrams. I have Rectangles with rounded corners and during the paint methods sub calls the image creation fails.

I think it fails because the OneLineMarginBorder objects int[] dash attribute is a null reference.

Is this a bug? Is there any workaround to avoid this?

Best regards
Mehmet Karaman

Hi Mehmet,

Thank you for your feedback,

Bug 484507 [1] has been created last week for the same NPE but in
another scenario (menu > copy, which on Windows place the result of a
CoptyToImage in the system clipboard).

A patch has already been provided, but the issue has not yet been added
to any roadmap. The patch targets master and the issue has been marked
as potential target for a backport on maintenance branches.

Do you have compartments on your diagrams ?

Regards

Maxime

Thank you for the reply.

Yes i have compartments. Is this problem related to compartments or rounded corner diagram elements?

This issue is related to compartments and their shared border, as soon
as there is more than one compartment in the same container.
