[JFace,Databinding]BooleanCellEditor not updating model [message #334748]

Hi,

I am trying to use BooleanCellEditor, that I found in JFace snippets, with
databinding to an EMF model object using ObservableValueEditingSupport.

But I think it is not updating the model object and also not working well
its LabelProvider. I tried to debug this and I think it is something about
deactivating. It just not triggers editor update so editingsupport is not
working to update. Well, I looked at ComboboxCellEditor code and updated
BooleanCellEditor deactivation with following:

Object newValue = doGetValue();
markDirty();
boolean isValid = isCorrect(newValue);
setValueValid(isValid);
fireApplyEditorValue();
deactivate();

Well it seems to update the model object now. But the problem is that, if I
enter editing mode and leave without changing the checkbox state, after
exiting editing mode LabelProvider does not show anything. I am not sure if
it is even called.

Can someone help me with this?

Thanks,
Tankut Koray

Could you provide a standalone snippet demonstrating the problem you're
seeing? This is tough to visualize
