Hi, When I change the value in the selectOneMenu which has an attached valueChangeListner, valueChangeListner event on an inputText control is also getting fired. This happens only the first time I submit after the page is loaded. Subsequent submits work fine. I couldn't figure out whether I am doing anything wrong. Following is the code..
