RE: Problems with client side state saving (and with server side state saving with IE)

________________________________

	From: Arinaya [mailto:arinaya@realidea.ca] 
	Subject: RE: Problems with client side state saving
	Interesting FYI,
	The below scenario works when the selectItems values are Integer
objects, but not when they are Strings.
	But Strings are ok with state saving method = server.

Interesting. I just run into a similar problem, which may or may not
have the same origins. I'm using server side state saving, and when some
of the Integer etc. bean properties that I'm trying to save using
saveState are null, IE crashes my server. And it only happens on IE, not
on Mozilla.. the logs are below.

		The following works perfectly when state is saved on the
server, but not when state is saved on the client. Can someone please
explain why. It looks like the valueChangeListener is not even being
triggered. What do I need to do to make JSF aware of changes to the
selectOneMenu input?
		 
		<h:selectOneMenu value="#{xxxBean.recordsPerPage}"
onchange="this.form.submit();" immediate="true">

		<f:selectItem itemLabel="10" itemValue="10"/>

		<f:selectItem itemLabel="20" itemValue="20"/>

		<f:selectItem itemLabel="50" itemValue="50"/>

		<f:selectItem itemLabel="All"
itemValue="#{xxxBean.recordCount}"/>

		<f:valueChangeListener
type="x.y.z.SatRecordsPerPageChangeListener"/>

		</h:selectOneMenu>
