extension of eclipse XMLMultiPageEditorPart - trigger refresh of tree-view manually

I am working on an eclipse-plugin which makes use of a custom XMLMultiPageEditor by extending XMLMultiPageEditorPart and XMLTableTreeView by extending XMLTableTreeViewer the second one as well implements a IResourceChangeListener.

I provide this plugin in eclipse-mars and eclipse-neon, however the wired behavior only shows up in eclipse-neon.

The editor works fine so far, the only problem is, that the tree-view is completely blank when a related xml-document is opened with it:

I can even modify the document in the source-view and save it .. the tree-view stays blank.

The only events which bring the tree-view to life are:

• re-size the editor-window with the mouse
• open some other document and than switch back to the tab of the open xml-doc.

After that, the tree-view works like it should. If I now change the xml in the source-view, the tree-view is updated immediately.

Any ideas how I could trigger a refresh of the tree-view manually ?

Is this maybe a bug in eclipse-neon ?

Ok, the problem seems to be, that the x/y size of the TreeViewer in eclipse-neon is initialized with (0,0). Here a hack to fix that:

...
public class MyXMLTableTreeViewer extends XMLTableTreeViewer implements IResourceChangeListener{
....

public MyXMLTableTreeViewer(Composite parent, IEditorPart parentEditor)
{
   super(parent);
   ....
   Point size = getControl().getSize();
   size.x = 1000;
   getControl().setSize(size);
}

It seems to be sufficient to only set x to some value ... 10 already gives an image, but the "node" section than looks a bit pressed, so I picket 1000.

Even if it is just internal API, it looks like a bug for me. So if you are further interested, take a look to the eclipse bugreport.
