selectOneListbox error - choosing menyitems rapidly

[ulf thoresen]

Hi!
I have the following problem with selectOneListbox in a jsp.

I have filled the list with listitems through binding like this:

<h:selectOneMenu id="_02Nedtrekkboks" value="#{ordreutvalg.kriterieUtvalg}"valueChangeListener="#ordreutvalg.kriterieutvalgHendelse}"
onchange="this.form.submit();document.getElementById('kriterieutvalg:_02Nedtrekkboks').disabled='false';">

<f:selectItem itemLabel="Velg kriterie" itemValue="0" />
<f:selectItem itemLabel="Leverand�r" itemValue="1" />
<f:selectItem itemLabel="Planogram" itemValue="2" />
</h:selectOneMenu>

when I stress the meny through clicking rapidly on menyitems in a browser then suddenly the hole page goes blank, and I get no exceptions.

Is there any other that have experienced this problem?
Can't this be because I have a submit on the event onchange?
