Hello!

I have a bordered item label that I can't move.

I debug my code, and I found that it doesn't arrive to the refreshBounds() method in the EditPart of the label.

I see the stack trace, and there's a moment in the DiagramEditingDomain class (into DiagramEditingDomainFactory) that does the postcommit (after release the mouse button) function.

This function check the existent notifications:
List notifications = getValidator().getNotificationsForPostcommit(tx);

But the list is empty, and there not arrive to the handleNotification of the labelEditPart.

Anybody can helps me please?

Thanks!
Marc

It seems like the EditPart isn't registered... I have created this EditPart manually. For other diagrams (i.e. Activity from UML) it works fine... Perhaps I must do something I don't realize with this "customized and manual" EditPart??

Thanks.

Hi,

Quote:

I have created this EditPart manually.

Rather than manually create and customized an EditPart I suggest you (1.) describe this element it in your .gmfgraph file somehow like:

    - FigureDescriptor VariableFigureDescriptor
        - Rectangle VariableFigure
            - Label VariableLabel
        - Child Access getFigureVariableLabel

Or a little bit more detailed.

    <descriptors
        name="VariableFigureDescriptor">
      <actualFigure
          xsi:type="gmfgraph:Rectangle"
          name="VariableFigure"
          outline="false"
          fill="false">
        <children
            xsi:type="gmfgraph:Label"
            name="VariableLabel"/>
      </actualFigure>
      <accessors
          figure="//@figures.0/@descriptors.3/@actualFigure/@children.0"/>
    </descriptors>

Furthermore (2.) create a node that uses the FigureDescriptor and (3.) introduce it in your .gmfmap file. Then (4.) (re-)create your generator model as well as (5.) your diagram editor.

Doing so (and assumed you're using a layout that actually allows moving nodes) you should be able to move the node.

Best regards,

sas
