[news.eclipse.platform] [DataBinding] Strange Behavior when binding to a

[Ali Naddaf <ali@xxxxxxxxxx>]

Hello All.

I posted a question a day ago and later on noticed that in fact the 
issue was had a different nature so here is my new problem. Let say I 
have the following snippet where I am binding the "name" field of the 
bean "ss" to a Combo called combo: ("dbc" is my databinding context)

-------------------
ss.setName("one");
combo= new Combo(group, SWT.NONE);
combo.setItems(new String[]{"", "one", "two"});
dbc.bindValue(SWTObservables.observeSelection(combo),
	BeansObservables.observeValue(ss, "name"), null, null);
------------------

When I run this, I will see "one" in the combo, as expected. However, at 
this moment, if I select "" (i.e. the empty selection) in the combo, the 
model (i.e. the "name" field in ss) doesn't get updated. If, on the 
other hand, I add the following line to the end of the above snippet, 
then all works as expected:

combo.setText(ss.getName());

Could someone please tell me what I am missing here?

Many thanks
Ali.
