Subject No RenderingContext with ajax4jsf + Seam
Date Tue, 27 Feb 2007 17:10:50 GMT
Hi @all,

I try using ajax4jsf 1.0.6 together with Trinidad, which works quite well so far and I can
use most of the ajax4jsf-components. The only thing, that does not work until now is using
the ajaxListener type="org.ajax4jsf.ajax.ForceRender" in a h:dataTable. What I want to do
is to rerender my selected row, so that I can display a delete-confirmation-box through setting
a flag and rerendering a defined part of the page. The ajax-request works perfectly, but unfortunately
I get an exception afterwards.

As I´m using the combination of Seam 1.1.6, MyFaces 1.1.5, ajax4jsf 1.0.6, facelets and a
nightly build of trinidad, I don´t really know what part causes this exception.

This is a short code-fragment:

<h:dataTable var="profile" value="#{ProfileList}" rendered="#{ProfileList.rowCount>0}">
            <h:column>                
                <a4j:commandButton    id="command_link_up" 
                                      value="Delete" 
                                      reRender="profile, deleteConfirmation" 
                                      action="#{OverviewAction.registerPublisherProfile}"
>
                    <a4j:ajaxListener type="org.ajax4jsf.ajax.ForceRender" /> 
                </a4j:commandButton>


                <a4j:outputPanel id="deleteConfirmation" ajaxRendered="true">
                    <h:panelGroup id="deleteConfirmationPanel" rendered="#{OverviewAction.deleteRequested}"
>
                        <div class="colored">
                            <tr:outputText value="#{messages['deleteProfile.confirmationText']}"
/>
                            ...
                    </h:panelGroup>
                </a4j:outputPanel>
            </h:column> 
...
And this is the exception I get:
