[richfaces-issues] [JBoss JIRA] Commented: (RF-1246) rich:datascroller - looks different before and after rich:dataTable

[Karl Traunmueller (JIRA)]

    [ http://jira.jboss.com/jira/browse/RF-1246?page=comments#action_12421308 ] 
            
Karl Traunmueller commented on RF-1246:
---------------------------------------

The issue is still present in RichFaces 3.2.1.GA

The relevant view fragment looks like this:

<pre>
<h:panelGroup>
		<rich:datascroller for="vehiclesTable" maxPages="10" status="status"
			scrollerListener="#{vehicles.pageChanged}" />
		<rich:dataTable id="vehiclesTable" value="#{vehiclesDataModel}"
			var="vehicle" rows="#{vehicles.dataModel.pageSize}">
</pre>

- vehicles is a Seam POJO
- pageChanged is a DataScrollerEvent listener 
- vehiclesDataModel is a lazy-loading paging table data model derived from ExtendedDataModel

> Simple action - commandLink run table filtering so table content sometimes are changed
> 1. For this sequence of code dataScroller is not displayed correctly. After filtering Rowcount in scroller keeps old count of rows and count of buttons pages is incorrect
> <a4j:commandLink actionListener="#{table.filter}"reRender="table,">
> <rich:datascroller align="left"  for="table" binding="#{table.dataScroller}" />
> <rich:dataTabl id="table" rows="10" value="#{parSlowList.parElSloTable}" ></rich:dataTable>
> 2. For this sequence everything is good. Scroller see correct table and row count
> <a4j:commandLink actionListener="#{table.filter}"reRender="table,">
> <rich:dataTabl id="table" rows="10" value="#{parSlowList.parElSloTable}" ></rich:dataTable>
> <rich:datascroller align="left"  for="table" binding="#{table.dataScroller}" />
> -----------------------------------
> My filter looks like :
> public void table.filter(ActionEvent event) {
>   loadTable(filterValue);
>   getDataScroller().setPage("first");
> //  getDataScroller().getDataTabe().getRowCount() <-- in first scenario this gave bad row count
>  }
> I think that UIDatascroller should contain resetDataTable method like UIDataFltrSlider or something is wrong in getDataTable - UIDataFltrSlider.getDataTable looks different than the same mathod in scroller.
> public void resetDataTable() {
>         getSession().remove("...");
>         getDataTable().setValue(getDataTable().getValueBinding("#{" + getForValRef() + "}"));
>     }
> ?
