The issue
I have Container Nodes representing components, hosting provided and required interfaces represented as bordered nodes. I want to force the required interfaces on the right/east side of components, and provided on the left/west side. I tried different things, but none worked. Here is a recapitulation of my tentatives and their result.
Tentative 1: The "org.eclipse.sirius.diagram.ui.styleConfigurationProvider" Sirius extension point
Inspired from:
Sirius Provide custom style
and
Sirius >> Problem with Bordered Nodes
I tried to use the org.eclipse.sirius.diagram.ui.styleConfigurationProvider extension point with my custom class implementing org.eclipse.sirius.diagram.ui.tools.api.graphical.edit.styles.IStyleConfigurationProvider, to match my components viewpoint mappings in the provides and createStyleConfiguration methods, and returning a custom class implementing org.eclipse.sirius.diagram.ui.tools.api.graphical.edit.styles.StyleConfiguration, to have my own getBorderItemLocator method, itself served by a factory class implementing org.eclipse.sirius.diagram.ui.tools.api.graphical.edit.styles.BorderItemLocatorProvider.
The latter custom factory class getBorderItemLocator method returns different GMF's "new BorderItemLocator(figure, PositionConstants.EAST/WEST/LEFT/RIGHT)" according to the "DDiagramElement diagramElementBorderItem" argument to match my provided/required interfaces, and I use the standard "new DBorderItemLocator(figure, PositionConstants.NSEW)" otherwise as default case, like in Sirius' DefaultBorderItemLocatorProvider class (line 55 in the link below).
When I enable breakpoints on the corresponding lines, it stops and everything is called. The problem is: It has no effect on the representation whatsoever... I don't know what to do.
Quick resources links for convenience (may not be up-to-date):
- BorderItemLocatorProvider.java
- DefaultBorderItemLocatorProvider
Tentative 2: GMF's "org.eclipse.gmf.runtime.diagram.ui.editpartProviders" extension point
Not being able to make the first tentative work according to the "provide custom style" documentation, I continued down the Sirius Provide custom style documentation page, and thought I would try the GMF way.
I created my own EditPartProvider extending GMF's AbstractEditPartProvider, matching my components thanks to the view.getElement() DNodeSpec/DNodeContainerSpec and its "actual mapping" for filtering, and then returning a custom EditPart class for my specific case.
I made my EditPart class extend Sirius' DNodeContainer2EditPart (since it was the kind of element I could find for my elements at debug time), and overriding its createBorderItemLocator method, using the same "BorderItemLocator factory" as in Tentative 1.
This time, I obtained a weird representation where all my components are displayed as a "double" graphical entity (I believe the original EditPart and graphical element is still created), and even if my BorderItemLocator code was called (breakpoints prove it), the Bordered Nodes interfaces are still not on any good side.
Conclusion:
What can I do to make my bordered nodes stick on the desired side if all this did not work...? Any idea/suggestion would be welcome 
Thank you !
