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.

Subject: RE: Problems with client side state saving

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>
