if you use ajax control to update the model - include datascroller id in reRender list.

I have the same problem,

I use myfaces 1.2.4 and richfaces 3.2.1, also tried 1.2.3 with 3.2.0.

Even if I reRender the datascroller it keeps showing the pages of the LAST data of the datatable.

<a4j:commandLink value="..." reRender="resultListTable,resultListDatascroller" ... />

<rich:datascroller id="resultListDatascroller" renderIfSinglePage="false" stepControls="hide" boundaryControls="show" fastControls="show" rendered="..." align="left" for="resultListTable" maxPages="10" page="..." />

<rich:dataTable rowKeyVar="pos" id="resultListTable" frame="void" border="0" rows="..." value="..." var="result">
<rich:column>
...
</rich:column>
</rich:dataTable>

Can anyone help?

We have two rich datatables with datascrollers and in one case it works fine, in other - the problem is reproduced. The reason between these tables is that in one case list instance is the same after update and in other (when wrong behavior) - new instance of list created each time. Have you any ideas, guys?

so just reset page binding in your action when you need to show new data in your dataTable.

Hi, we have a similar problem, using RichFaces (3.3.0.GA) and Seam.
This is the case:

<a4j:repeat  value="#{grupos}" rowKeyVar="row" var="grupoVar">
    <a4j:outputPanel id="panelItems" >
        <h:form>
            <rich:dataTable  id="itemListId" value="#{itemsList}"
                var="itemVar"                    
                rows="5" rowKeyVar="rowItem">
               
                <f:facet name="footer">
                    <rich:datascroller id="listScroller" for="itemListId"
                        align="left" fastControls="hide"
                        pagesVar="pages"
                        page="#{actionUI.scrollerPage}"
                        scrollerListener="#{actionUI.busquedaPaginada}"
                        reRender="panelItems"
                        eventsQueue="#{eventsQueue_param != null ? eventsQueue_param : 'default'}" >
                        ...
                        ...

The rows generated by a4j:repeat behaves like a toogle panel, when a button is clicked, one table is shown and the others are hidden.
If I go to the second page on any table, and after that I open another one wich only has one page,  the DataModel is updated
I have a new search to populate the rows to show, but the rowKeyVar from "itemListId" table, remains on the index set by the first
pagination made.

actionUI.scrollerPage, shows the correct first page (index 0 for the new DataModel), but rowKeyVar does not, it keeps the value from the first pagination.

We did tests:

• without a4j:repeat, putting by hand the rows from "itemListId" table, and there we had no problem, each table  works fine, as we expect.
• replacing a4j:repeat with another rich:dataTable, and the problem persists
• rich:dataTable and a rich:subTable as children, no luck
• replacing a4j:repeat with ui:repeat (even though is not a real option, since we need the "rowKeyVar"), but it does not work either.

Anybody know a solution, what the  problem is, or any other alternative to have a variable list of tables in a sroollable way.

Moving to RichFaces space as nto related to actual RichFaces development.

At first please upgrade RF to latest 3.3.3 CR.

I'm not sure that completelly understand the case. which rowKeyVar? repeat? table? And how does that affects the result?

actionUI.scrollerPage, shows the correct first page (index 0 for the new DataModel), but rowKeyVar does not, it keeps the value from the first pagination.

Some ready to run sample would be great.

I'm having the same problem with the dataScroller inside an a4j:repeat. When I click on the numbers in the dataScroller to change the page the datascroller stays on the first page and the dataTable keeps showing the data of the first page. When clicking on one of the number in the dataScroller, the datamodel is called but the range parameter provided to the walk() method of the dataModel contains the wrong firstRow (always 0).

I'm using the a4j:repeat tag to iterate over a list of dataModels for which a dataTable and dataScroller will be created.This because I have a dynamic number of dataTables which I need to show.

<a4j:repeat value="#{myBackingBean.dataModelList}" var="dataModel">

     <rich:dataTable id="myTable" value="#{dataModel}" var="mainVar"
          rows="#{dataModel.amountOfRows}" first="#{dataModel.first}">

          // columns of the table ....

     </rich:dataTable>

     <rich:datascroller id="myDataScroller"
          for="myTable"
          maxPages="7"
          renderIfSinglePage="false" ajaxSingle="false"
          page="#{dataModel.currentPage}"
          scrollerListener="#{dataModel.scrollerListener}" />

</a4j:repeat>

<t:saveState value="#{myBackingBean.dataModelList}"/>

We use a custom dataModel which extends from SerializableDataModel, in which we enable real database pagination of data.

But when I try the following(makes no sense really, but was just to see whether pagination would work this way), the pagination is working correctly:

<a4j:repeat value="#{myBackingBean.dataModelList}"  var="dataModel">

     <rich:dataTable id="myTable" value="#{myBackingBean.dataModelList[0]}"  var="mainVar"
           rows="#{myBackingBean.dataModelList[0].amountOfRows}"  first="#{myBackingBean.dataModelList[0].first}">

          // columns of the table ....

     </rich:dataTable>

     <rich:datascroller id="myDataScroller"
           for="myTable"
           maxPages="7"
           renderIfSinglePage="false" ajaxSingle="false"
           page="#{myBackingBean.dataModelList[0].currentPage}"
           scrollerListener="#{myBackingBean.dataModelList[0].scrollerListener}" />

</a4j:repeat>

In this example I directly reference the first datamodel in the list and it works. The first example also doesn't work when there's only one dataModel in the list.

Before making the post above, I upgraded RF to 3.3.3.CR1, but I'm still having the same problem.

Hi Ilya, before anything, thank you for your will to help.

Upgrading is not our first choice have right now (we have plans to the upgrade, but not at the moment), since we already have several pages in production without major problems, and only a small percentage with this particular problem.

In case you have the time, here are some code (I hope ready to run )  wich produces the problem.

Is very similar to Yennick's case, but we use the scroller insede the facet:footer.

Steps to reproduce:

- Click on "Init Data" button. (this populates the lists)

- Click on first "Show" button and go to page 2.

- Click on second "Show button" and there's no row showed.

Thanks in advance

Ale

I found a solution for the problem. While searching for a solution I stumbled upon this article about a4j:repeat and tabs, menuItems etc. http://community.jboss.org/wiki/Cantusea4jrepeattoiteratethemenuItemstabsetc

So I tried to use the c:forEach instead of the a4j:repeat and now it works. Don't know whether the explanation given in the article is also valid for this problem, but it works.

Hi,

rich:datascroller for nested iteration components (e.g. rich:dataTable inside a4j:repeat) is not supported currently. There's JIRA issue for this problem.
