[richfaces-issues] [JBoss JIRA] (RF-11434) datascroller broken in 4.1.0.M1

[Brendan Healey (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/RF-11434?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12635012#comment-12635012 ] 

Brendan Healey commented on RF-11434:
-------------------------------------


I now realise that this issue was caused by the fact that I'd turned partial
state saving OFF on the view in question with this context parameter:

<context-param>
    <param-name>javax.faces.FULL_STATE_SAVING_VIEW_IDS</param-name>
    <param-value>/secure/myView.xhtml</param-value>
</context-param>

I just tested on 4.1.0.M2 and with partial state saving enabled the datascroller
works ok, with it disabled it doesn't.

I was turning partial state saving off to use 'dynamic ui:include', due to a
known mojarra bug/restriction. Because of the complications I've stopped using
this approach.

So datascroller is working ok for me. I would suggest that perhaps it would be
prudent to make a call on whether or not full state saving is supported or not?
I don't know whether or not the position on this is already established. During
the test I carried out above, I noticed (out of the corner of my eye) a
selectionchange event not firing on an extendedDataTable with partial state
saving disabled, suggesting perhaps that there are multiple issues.

> I have an extendedDataTable with a datascroller. The first page of results
> displays correctly, but on pressing the control for page 2 (or any other)
> nothing happens. Using a4j:log I see that the ajax response to the post
> request contains a java.lang.NullPointerException.
> On reverting to 4.0.0.Final it works successfully. The problem also affects
> a rich:dataTable. I've not been able to locate the M2 release in the Maven

> The extendedDataTable value attribute value is a straightforward List<Event>
> where Event is a standard pojo. I was using ExtendedDataModel but removed
