partitioning or subdiagram problem [message #633114]

Hello Community,

I added to my gmfmap and gmfgen necessary settings to get OpenDiagramEditPolicy when I doublecklick on an element. That works fine.
But there is a curious behavior: after doubleklick I open a new diagram and add new elements from the toolpalette and press save and close the diagram.
Now, when I move a element on the main diagram and press save, and after open the subdiagram again - all elements are lost in the subdiagram!? Why?

How can I solve this problem? Please help Smile

thx

I tested it out with an older version of my editor - there it works fine.
When I close the subdiagram there apear a dialog "The File has be changed on the Filesystem, do you want load the changes" I choose yes and everything works.

But in my new version, this dialog does not appear, why? thx

This problem occures, because I save my diagram in a project in my workspace, but I do something wrong, so my diagram doesn't recognize changes on filesystem. How to correct this? Thx

No I'm a step further.

I got this behavior because I use the Eclipse Resource API, so now I have to implement a Resourcelistener for my diagram like:


IWorkspace workspace = ResourcesPlugin.getWorkspace();
   IResourceChangeListener listener = new IResourceChangeListener() {
      public void resourceChanged(IResourceChangeEvent event) {
         System.out.println("Something changed!");
      }
   };
   workspace.addResourceChangeListener(listener);

   //... some time later one ...
   workspace.removeResourceChangeListener(listener);

described here: http:// www.eclipse.org/articles/Article-Resource-deltas/resource-de ltas.html

so I did, and it works fine.

But how can I perform a model-file synchronisation on my diagram in gmf? Thx
