Class: org.zkoss.zkex.zul.SimpleListModelSharer

ListModelOperation(int op, int index, T value,ProxyModel<T> model)

{ this._op = op; this._index = index; this._value = value; this._model = model; <<< Following line is missing in the code. I added this and the code is working as expected. }

This causes system to throw error message when the model is updated.
