Data Inputs and Data Outputs are not being rendered

[SimonHe77wer]

I trie to create png from a bpmn file (created with eclipse bpmn modeler). The bpmn can be modeled with a single activity and a data object as input. After creating a png with bpmn-to-image myBPMN:myBPMN.png the png does not show the data object. When modeling a data object reference this reference shows in the final png, but not the data object itself.

Could you share a screenshot of your modeled diagram as well as the resulting BPMN file? That helps us to look into the issue.

So the issue is that the Data Object is part of an IO specification.

Rendering IO Specification is, unfortunately, not supported by the tool yet. Upstream issue: https://github.com/bpmn-io/bpmn-js/issues/951.

Hi @nikku , thanks for your response. We found out that DataInput and DataOutput are rendered. This is not correct from a model perspective but works for us as intermediate solution. Looking forward to the improvement :-)

Here is another good example that's missing nowaday

Also consider, those annotations pipelined upto a db that indicate what comes in and out the db itself (may be not executable, but a good contrib during the modeling phase anyway)
