    [ https://issues.jboss.org/browse/RF-11575?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12636111#comment-12636111 ] 

Lukáš Fryč commented on RF-11575:
---------------------------------

I have reproduced on following Metamer page (just added execute=@form to datascroller):
http://localhost:8080/metamer/faces/components/richDataTable/components1.xhtml

The problem is in following method:

{code:java|title=javax.faces.component.UIInput:updateModel:804}
public void updateModel(FacesContext context) {

        if (context == null) {
            throw new NullPointerException();
        }

        if (!isValid() || !isLocalValueSet()) {
            return;
        }
        ValueExpression ve = getValueExpression("value");
{code}

When sending request with commandButton, {{isLocalValueSet == true}},

but when executing using dataScroller[execute=@form], {{isLocalValueSet == false}}, so method returns prematuraly.

Need to debug more

> In RF-10936, Ajax attributes was enabled to dataScroller to enable execute=@form, which effectively allows user to save table values when changing page, but the functionality still doesn't work - form is processed but model is not updated.
> {code:XML}
> <rich:dataTable var="person" value="#{people}>
>   ...
>   <h:selectBooleanCheckbox value="#{person.sex}" />
>   ...
>   <rich:dataScroller execute="@form" />
>   ...
> </rich:dataTable>
> {code}
