Hi all,
I have an annoying Warning :

java.lang.RuntimeException: WARNING: Prevented recursive attempt to
activate part org.eclipse.ui.views.ContentOutline while still in the
middle of activating part editor

appearing when I open an editor from another editor by the command :
IEditorPart editor = IDE.openEditor(page,editorInput,EDITOR_ID,true);
and when I come back to the first editor.

Does anyone have a hint ?

Regards.
Christophe

Can you please file a bug for this, ideally with steps to reproduce? Are
you opening the other editor while the first editor is being opened? If so,
it might help to call IDE.openEditor from an asyncExec.

New focus event is run while other focus event was executing and therefore not finished yet.

You have to override setFocus() or find a good place and put this inside your code:
Display.getDefault().asyncExec(new Runnable() {
@Override
public void run() {
while (Display.getDefault().readAndDispatch()) {
//wait for events to finish before continue
}
// your code for focus here
// e.g. table.forceFocus()
}
});

So Display will wait until current focus event is finish, and then will execute new focus event.
