Absolute positioning of flow labels

roguemonkey — Wed, 20 Aug 2014 14:56:10 GMT

When generating a diagram image from java code running with the 5.15.1 engine, the flow labels are all pushed to the the bottom right of the Diagram. Generating the same image from within the Eclipse Designer works as it should.I suspect that it is related to this bug?http://jira.codehaus.org/browse

Upgrading to 5.16.1 changes the look of the diagram, the colors are more muted, the icons are golden instead of black and blue. The labels have moved… but are still at the wrong place. They are now semi randomly positioned on the screen (can' discern a pattern) instead of being all pushed to the bottom…

I tried setting the position of the label to 0x 0y, but to no avail? It stayed right on the same spot on the diagram.

Before:

      <bpmndi:BPMNEdge bpmnElement="flow6" id="BPMNEdge_flow6">
        <omgdi:waypoint x="400.0" y="326.0"></omgdi:waypoint>
        <omgdi:waypoint x="399.0" y="410.0"></omgdi:waypoint>
        <omgdi:waypoint x="522.0" y="410.0"></omgdi:waypoint>
        <bpmndi:BPMNLabel>
          <omgdc:Bounds height="12.0" width="90.0" x="439.0" y="557.0"></omgdc:Bounds>
        </bpmndi:BPMNLabel>
      </bpmndi:BPMNEdge>

After:

      <bpmndi:BPMNEdge bpmnElement="flow6" id="BPMNEdge_flow6">
        <omgdi:waypoint x="400.0" y="326.0"></omgdi:waypoint>
        <omgdi:waypoint x="399.0" y="410.0"></omgdi:waypoint>
        <omgdi:waypoint x="522.0" y="410.0"></omgdi:waypoint>
        <bpmndi:BPMNLabel>
          <omgdc:Bounds height="12.0" width="90.0" x="0.0" y="0.0"></omgdc:Bounds>
        </bpmndi:BPMNLabel>
      </bpmndi:BPMNEdge>

I also notice that moving to 5.16.1, it's not only the colors that changed, but also the fact that boxes that could fit the whole text (just like on the Eclipse Designer plug-in) now show ellisions (…) and loses the end of the text. That's an inconvenient regression for me, as I make sure that all the text in the diagram is legible when I create boxes in the designer.

The issue you mention indeed fixed a very nasty bug - but as a side effect all the previous processes could have wrong labels … as you indeed noticed yourself.

The proces diagram has gotten some attention lately, and has many new improvements.

How is it possible that 3 ellisions are shown now if you make the rectangles big enough? Is there that big of a difference in fonts?
