Rich:datatable : clientsRow ajax loading, loading image.

[popo_joe]

Hello,

        I am currently working with a rich:extendeddatatable on rich version 4.2.2Final, the ajax loading works great, but my problem is that i want to put a loading image when the user scrolls while the data is being retrieved from the server.

Is it possible with actual richfaces components? or do i have to hack my way through with JQuery/JS/Whatever?

thanks alot!

Hello John,

I am not sure whether I understand you correctly. Do you mean something like in this example:

http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=status&sample=viewUsage&skin=blueSky

the spinning circle while you are writting into the inputs ?

Hello juraj,

              I would like to display a spinning circle when the user is scrolling poutside of the clientsRow loaded rows in the rich:datatable.

cliensRow is the number of rows loaded to the browser.

i have a huge datatable with 5000 rows, and i am loading 100 rows at a time, when the user scrolls outside of those 100 loaded rows, he can only see blank space, until the next 100 rows are displayed. I just want to put a loading image in the blank space.

I have achieved your your desired behavior when I put a4j:status component outside the rich:extendedDataTable component.

So in this example:

http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=extendedDataTable&skin=blueSky

the end of facelet will look like:

  <rich:column>

     <f:facet name="header">

          <h:outputText value="Days Live" />

     </f:facet>

     <h:outputText value="#{car.daysLive}" />

   </rich:column>

</rich:extendedDataTable>

<a4j:status >

  <f:facet name="start">

      <h:graphicImage value="path/to/spinning/image.gif"/>

  </f:facet>

</a4j:status>

</h:form>

Is this a solution to your problem ?

Your proposed solution did not work for me. I have a view level a4j:status component but the extendedDataTable does not use it. It does not have a status attribute eighter nor an event for ajax load.
