Why is CompatibilityPart eating my PartInitException ? [message #1753320] Fri, 03 February 2017 18:53

Hello,

I'm trying to integrate the subclipse plugin in my RCP application, but I have a problem when I try to open remote files with my home-made editors.

All these editors expect an IFileEditorInput, and not RemoteFileEditorInput.

So when the user double clicks on a file in the History View or in the remote repositories view, I would like he simple sees the raw text of the file.

Now this is something which is foreseen by the subclipse plugin : in the org.tigris.subversion.subclipse.ui.actions.OpenRemoteFileAction, the plugin looks for the default editor, tries to open it with a RemoteFileEditorInput. If the editor throws a PartInitException, subclipse simply invokes the default text editor and everything should work as a charm...

BUT, that may have worked fine in Eclipse 3.*, but now, in Eclipse 4.5 at least, all PartInitExceptions are catched by the Class CompatibilityPart, who opens an Error Message. Very ugly for my users...

I worked around this limitation by the following code in my Editor#init method, but it does not feel very clean :

 if (editorInput instanceof RemoteFileEditorInput) {
                try {
                    super.init(site, new NullEditorInput());            
                    site.getPage().closeEditor(this, false);
                } catch (Exception e) {
                    // this catches a bunch of NPE
                } finally {
                    IWorkbenchPage page = PlatformUI.getWorkbench()
                            .getActiveWorkbenchWindow().getActivePage();
                    try {
                        page.openEditor(editorInput,
                                "org.eclipse.ui.DefaultTextEditor");
                    } catch (PartInitException e) {
                        // 
                    }
                }
                return;


Any ideas to cope in a better way with this problem ? Any input would be welcome!
