      Description

      We have a situation where some Java code is changing a model in a Selectbox (because some other value changed).
      After doing this, we then set a selection on the new model [using model.setSelection() ].
      This work most of the time.
      However:
      1) if something had already been selected in previous model; (e.g. the 3rd element in the list) and,
      2) if the new model has less elements that the element that was previously selected (e.g. new model has 2 elements)
      we get an error. [See stack-trace below]
