No support for <rich:columns> in RF 4.0.0 CR1?

ahoehn Mar 14, 2011 4:56 AM

I've got a problem when I try to use the tag <rich:columns> in RF 4.0.0 CR1 the renderer returns the message "<rich:columns> Tag Library supports namespace: http://richfaces.org/rich, but no tag was defined for name: columns"

Tags like rich:dataTable and rich:column are working, but the columns-iterator not. Has something changed in RF 4 for this tag? Is this tag not anymore supported? (http://docs.jboss.org/richfaces/latest_3_3_X/en/devguide/html/rich_columns.html)

Thanks for your support,

Adrian

unfortunatelly out of Final scope. Will be migrated later. And for now could use just c:forEach with column as for any other components.

I tried to surround my <rich:column> with <c:foreach> but it didn't work.

Is there any other possibility to deal with this in RF4 ?

c:forEach should work. Please post page/bean code.

Code of the xhtml-Page:

<rich:dataTable value="#{teamHandler.mitarbeiter}" var="m">
                    <rich:column>
                        <f:facet name="header">Mitarbeiter</f:facet>
                        <h:outputText value="#{m.name}" />
                    </rich:column>
                    <c:forEach items="#{datumsHandler.span}" var="d">
                        <rich:column>
                            <f:facet name="header">
                                <h:outputText value="d" />
                            </f:facet>
                            <h:outputText value="-" />
                        </rich:column>
                    </c:forEach>
 </rich:dataTable>

teamHandler.mitarbeiter <- ArrayList of my class Mitarbeiter (m.getName() returns a String)

datumsHandler.span <- ArrayList of Strings

I can ensure that the data produced by the managed beans are correct.

(creating a simple html-table with two <a4j:repeat>-Tags works fine)

How does namespace for c:* tags is declared?

Checked and works for me. Can you please prepare example application reproducing the problem?

now it does work - thanks a lot !
(my namespace in the specific file was corrupted - respect that you detected this without having the appropriate code)

Will this work with some kind of input field in the columns?

hmm have tried the following and it's not functioning:

<rich:dataTable value="#{listOfRows}" var="myRow" rowKeyVar="rowIndex">
    <rich:column>
        Rownnr#{rowIndex}
        <c:if test="#{myRow != null}">
            is not null for jstl
        </c:if>
    </rich:column>
</rich:dataTable>

Is something wrong in my code or is there no way (because of rendering jstl earlier than rich:dataTable) to access the var of the rich:dataTable with jstl?

One problem seems to be that @ViewScoped breaks when any UIComponent is bound to the bean using binding attribute or when using JSTL <c:forEach> or <c:if> tags in the view.

I guess I'll wait until this is merged since I'm using @ViewScoped heavily. Any ideas of when it will happen?

Thanks!

Component instances should not be bound to the objects which live longer the requests. And that's not a RichFaces limitation but just JSF known problem.

That will not work.

c:if and dataTable evaluated at different lifecycle places. So var of the dataTable not accessible when c:if evaluates the condition.

changes to just rendered attribute usage.

if you using c:forEach for example to generate set of columns - it should be also pointed to some collection not using var expressiopn but directly.
