I was playing with this AJAX functionality and I found some strange
behaviour. If the component id is not the same as element id, the form is
submitted, but the event listener method is not processed. Everything work
fine in this case:
<input jwcid="[EMAIL PROTECTED]" value="ognl:isin" id="isin" />
@EventListener(events="onchange", targets="isin")
public void onRefresh(IRequestCycle cycle) {
log.debug("*** AJAX ***");
}
But if I change the component id, the method is not called:
<input jwcid="[EMAIL PROTECTED]" value="ognl:isin" id="isin"
/>
@EventListener(events="onchange", targets="isinComponentID")
public void onRefresh(IRequestCycle cycle) {
log.debug("*** AJAX ***");
}
Maybe some kind of conflict between component id and DOM id ?
