I am using Eclipse Luna (4.4.0) for RCP and RAP Developers. Is there yet a (simple) possiblity to use e3 editors (e.g. AbstractTextEditor or XMLMultiPageEditorPart) in a e4 RCP application?

All I have found is a rather complicated looking method in Lars Vogel's migration tutorial involving a modified LegacyIDE.e4xmi. There Lars also mentioned that Eclipse 4.4 plans to to enhance the support for mixing 3.x and 4.x API components. Unfortunately the linked bug report still has the status "NEW", so that method obviously has not been implemented yet.

Is there any other option?

Thanks
Ulrich

Hi Ulrich

how did you manage to get the editors working?

Not at all, so far. Still waiting for a hint. It should be possible, as Eclipse 4 itself uses the XMLMultiPageEditorPart, but I don't have a clue, how it is done.

Here is what I did so far:

(1) I created a Area with the id "org.eclipse.ui.editorss" in the .e4xmi
file. (I debuged the openEditor code to find out how e4 findes the area to
open the editor in ... and it actually searches for the area with the id
mentioned above. Be aware of the double ss!

(2) I created a StackPart as the child of the area file
(3) I created a MPart in the e4xmi file :
(3.1) added an id
(3.2) added a label
(3.3) added the class uri
"bundleclass://org.eclipse.ui.workbench/org.eclipse.ui.internal.e4.compatibility.CompatibilityEditor"
(3.4) now the compatibilityEditor class still needs to know which "old" e3
Editor it should wrap. I used the "Live Model Editor" view of e4 to see
how eclipse does it. obviously they add memento in the persisted state
with the following value:

<persistedState key="memento" value="<?xml
version="1.0" encoding="UTF-8"?>
<editor
id="org.example.ABCEditor"/editor>"/>

with org.example.ABCEditor beeing the e3 class implementing the editor

So now my editor opens in the area, but I still have problems since it
disapears again when I resize the window. (It will show as soon as you do
something which causes the area to be rendered again, like resizing the
SashContainers ...

Hope this helps

Hi Martin,

thanks for sharing your progress.

I tried to follow your instructions as a starting point, but got the error message "Could not find satisfiable constructor in org.eclipse.ui.internal.e4.compatibility.CompatibilityEditor". It seems that the Injector cannot inject the EditorReference needed by the CompatibilityEditor. For memento I have specified an e3 Editor extending AbstractTextEditor which in turn extends EditorPart. Do I need something in the plugin.xml, or do you see any other mistake?

Regards

Ulrich

Actually I would be surprised that this would have th cause in the DI
since the DI is massaging the CompatibilityEditor class as I understand it
- strange. Do you have the stack trace? Also the MPart definition in the
e4xmi file might help ...

Unfortunately not. Presently I'm using e3 plugins in compatibility mode.
