@aria:Select widget behaves incorrect when bound options change

[carlo-mr]

When binding the options of an @aria:Select, the display is reset to the first value but the value in the data model does not change.

See the Example in Instant AT.

Workflow to reproduce:

1. Select 'B' in the right select box
2. Switch to "Type B" in the first select box
3. Click the Button.

The data model has the values "B" and "B" but the display shows "B" and "A".

Even worse:

1. Select "Type B" in the first select box.
2. Select "C" in the right select box.
3. Switch back to "Type A".
4. Click the Button.

The data model contains the values "A" and "C", where "C" is not even a correct value for "Type A".

The problem seems to be in the _onboundPropertyChange-Method in the Select widget. Which - after setting the new options - calls controller.checkValue with null instead of the current value.

If the display of the widget is reset after changing the options then the bound property should also be resetted. Or if the bound value is contained in the new options-list it should be directly selected.

This might apply to all "DropDownInputs".

In aria.widgets.form.Select replace lines 420 - 423 with the following and this seems to fix the issue...

var report = this.controller.checkValue(this._cfg.value);
this._reactToControllerReport(report, {
       stopValueProp : false
});

The first scenario was fixed in 1.6.5 via #1274
The second scenario is still reproducible as of 1.6.5

This will be fixed in 1.6.6, @carlo-mr @dpreussner thanks for your contribution!
