rich:dataTable and rich:dataScroller inside h:panelGroup - doesn't display the correct number of rows when number of rows is updated ------------------------------------------------------------------------------------------------------------------------------------ Key: RF-12289 URL: https://issues.jboss.org/browse/RF-12289 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-tables Affects Versions: 4.2.1.Final, 4.2.2.Final, 4.3.5 Reporter: Nicolas Daniels Fix For: 5-Tracking Attachments: another-reproducer.zip, richfaces-sandbox.zip, rich_dataTable-rows.png, test.jspx, TestFace.java Trying to have datascroller with dynamic rows number, but it works only if dataScroller is above the table. Basically, what I have is: <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> 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)
