Brian Leathem updated RF-12289:
-------------------------------
Description:
Trying to have datascroller with dynamic rows number, but it works only if
dataScroller is above the table.
Basically, what I have is:
{code}
<h:selectOneMenu value="#{myBean.batchRows}">
<f:selectItem itemLabel="10" itemValue="10"/>
<f:selectItem itemLabel="20" itemValue="20"/>
<f:ajax render="table table-ds" />
</h:selectOneMenu>
...
<h:panelGroup>
<rich:dataTable id="table" rows="#{myBean.batchRows}"
value="#{myBean.dataModel}" var="var">
...
</rich:dataTable>
</h:panelGroup>
<rich:dataScroller id="table-ds" page="#{myBean.batchPage}" for="table"
renderIfSinglePage="false" boundaryControls="hide" fastControls="hide">
...
</rich:dataScroller>
{code}
And the behaviour with 21 elements:
- on page 2 displaying 20 element (so only 1 is visible), if I switch to 10, I
stay on page 2 but I still have only 1 element visible.
If my datascroller is above my table it works fine. If the table is not wrapped
within a panelGroup, it works as well.
Debugging a bit, it seems that when UIDataAdaptor.walk method is 1st called,
getComponentState() is updating the state rows and first properties with values:
- rows: 10 (correct)
- first: 20 (weird)
Following calls to this method is setting those properties to:
- rows: 10 (correct)
- first: 10 (correct)
