              Marc Schmucki Newbie

              Hello

               

              We had a similar problem. What happens if you give the links a generated id? We had code like that:

               

              <rich:dataTable id="matrix"

                                          value="#{model.rowHeaders}" var="row"

                                          rowKeyVar="curRow" style="width:auto; white-space:nowrap;">

              ...

              <rich:columns value="#{model.columnHeaders}"

                                              var="columns" width="auto" index="ind" align="right">

                                              <a4j:commandLink id="a_#{ind}_#{curRow}"

                                                  action="#{action.selectCurrentPos(ind, curRow)}">

              ...

              </rich:dataTable>

               

               

              Or maybe also rerendering the link / table on change page helps...

               

               

              Greetings

                We have the same Problem (JSF 2 myfaces 2.1.2 / Richfaces 4.1.0.M1)

                 

                inside rich:datatable we have places a h:commandLink wich provides download functionality. On Page 1 (rich:datascroller) everything is work as expected.

                 

                If i ever switch to any other Page, the commandLink will not get executed. It simply renders the page again. No matter if i use the a4j:CommandLink or the h:commandLink.

                 

                <rich:column style="width: 25%;">
                     <f:facet name="header">
                          <cmp:sortableHeader controller="#{repositoryListController}" label="#{messages.repository_column_fileName}" sortKey="fileName" />
                     </f:facet>
                     <h:commandLink value="#{item.fileName}" action="#{repositoryListController.processDownloadContent(item)}" target="_blank" />
                </rich:column>
                

                 

                 

                Any suggestions?

                  Ok what i found till now is following:

                   

                  the use of myfaces 2.1.1 brings some problems. After downgrading to version 2.0.6 (not 2.0.7 and neither 2.1.0) the above problem was gone.

                  Strange!

                   

                  I think there are many issues dependeing on which version of the underlying jsf implementation is used.

                  With myfaces 2.0.6 i could use my commandLinks inside rich:dataTable without problems.

                  But if i display a rich:tree there are some problems with image resources (not found under expected resource org.richfaces.images which is only a virtual mapped path).

                  So my Workaround was to copy the images from org.richfaces resource folder to my resource/org.richfaces.images folder and the rich:trees begin to shine ;-)

                   

                  Hope these Problems will be fixed in richfaces 4.1 final ... or is it a myfaces problem?
