    Strange symptom with rich:dataTable used with @DataModelSele

    Tony Mai Apprentice

      Hello all,

      I've been using rich:dataTable together with Seam's @DataModelSelection for several pages in my app without any problem. However, one of the pages I have displayed weird symptom where regardless of which row I clicked on, the @DataModelSelection would always default to the last row in my table.

      Any ideas on how I would go about debugging this error? I am using RichFaces 3.0.1GA and Seam 1.2.1GA under JBoss 4.0.5GA.

          You'll need to use your debugger to look in the javax.faces.model.DataModel.getWrappedData() method and see whats going on.

            What kind of link is it you are clicking on?

            I had a weird error where I was getting the same value in my data selection, and it seemed to be because I was returning a page flow action in the command link

            <h:commandLink action="editMyObject"/>

            It appeared that when I did this, the data model selection was not updated, and when I got to my new page, the same object was selected no matter what link I selected :

            <h:commandLink action="#{myEdit.editMyObject}"/>
            which is defined as :
            public String editMyObject() {
             return "editMyObject";

            works fine and the right object was selected when I got to the next page.

            Might be something worth looking at and trying if it is applicable. I was also using the rich data table, and the same Richfaces and seam versions as you.
