Erik-Berndt Scheper commented on MYFACES-562:
---------------------------------------------
My mistake, wrong cut & paste...
It should have been something like:
<t:dataTable id="data" sortColumn="#{pagedSort.sort}"
sortColumnAscending="#{pagedSort.ascending}" ... >
<t:column>
<f:facet name="header">
<t:commandSortHeader columnName="name"
immediate="false" actionListener="#{pagedSort.sortActionListener}">
<f:facet name="ascending">
<h:graphicImage
url="/images/arrow-asc.gif" style="border:none"/>
</f:facet>
<f:facet name="descending">
<h:graphicImage
url="/images/arrow-desc.gif" style="border:none"/>
</f:facet>
<h:outputText value="#{msg['label.naam']}" />
</t:commandSortHeader>
</f:facet>
<h:outputText value="#{employee.name}" />
</t:column>
..
</t:dataTable>
The problem is that the actionListener of the sortHeader tag (method
sortActionListener() of pagedSort.java) is called before the properties
"#{pagedSort.sort}" and "#{pagedSort.ascending}" have been updated.
> <t:commandSortHeader> processes action / actionListener before updating
> values of sortColumn and sortAscending

> URL: http://issues.apache.org/jira/browse/MYFACES-562
> Project: MyFaces
> Type: Bug
> Components: Tomahawk
> Versions: 1.1.0
> Reporter: Erik-Berndt Scheper
>
> At the moment <t:CommandSortHeader> processes an action / actionListener
> before updating the values of sortColumn and sortAscending. The reason is
> that in the broadcast() method of HtmlCommandSortHeader.java, the method
> super.broadcast(event) is executed before the values are updated.
> The consequence of this bug is that in the methods called by the action /
> actionListener, the sortColumn and sortAscending properties of the datatable
> still have the old value. Which in turn means that any sorting performed in
> the action / actionListener methods lead to incorrect results.
> Suggested solution: call super.broadcast(event) AFTER the values of the
> datatable have been updated.
