| Why ColumnViewerEditorActivationListener isn't called [message #330321] |

I have created a TableViewer and register a listener, which isn't called
at all, even when I double click a cell in order to edit it.
tableViewer.getColumnViewerEditor().addEditorActivationListe ner(new
ColumnViewerEditorActivationListener() {
@Override public void
afterEditorActivated(ColumnViewerEditorActivationEvent event) {
}
@Override public void
afterEditorDeactivated(ColumnViewerEditorDeactivationEvent event) {
}
@Override public void
beforeEditorActivated(ColumnViewerEditorActivationEvent event) {
CrudContentProvider.this.beforeEditorActivated(event);
}
@Override public void
beforeEditorDeactivated(ColumnViewerEditorDeactivationEvent event) {
}
});

I'm going to explain more in depth my problem.
In my TableViewer, when the user changes the current row, its contents are
validated, and saved. If they aren't correct, the selection is set back
to the edited row.
I do this thru a selection listener:
viewer.addSelectionChangedListener(selChanged = new
ISelectionChangedListener() {
public void selectionChanged(final SelectionChangedEvent event) {
selectionChanged();
}
});
int lastIndex;
Object lastSel;
protected void selectionChanged() {
if (ignoreSel > 0) {
return;
}
ignoreSel++;
try {
IStructuredSelection sel =
(IStructuredSelection)viewer.getSelection();
Object sel1 = sel.getFirstElement();
if (sel1 == lastSel || saveCurrentRow()) {
lastSel = sel1;
lastIndex = viewer.getTable().getSelectionIndex();
} else {
viewer.cancelEditing();
// If we cannot save current row, then come back
viewer.getTable().setSelection(lastIndex);
}
} finally {
ignoreSel--;
}
}
The problem:
One the user double clicks a cell in another row, that cell is activated,
even though I set the selection back to the old row.
How can I stop the activation going to that cell?
Any help will be grealty appreciated.

Please provide a fully running snippet and then file a bug. CC me and
Boris and we'll have a look.
