empty table column header on a dataTable when trying to fill it dynamically...

[Axel Wittich]

Hello all,

I currently have a problem with a dataTable.

I want to display the value of a data object as table column header - the object contains data (when I use it to populate a row, the data is displayed), but it is not displayed within the table header (see 3rd column):

    <rich:dataTable
        id="statusResultOverviewTable"
        style="background-color: #f5f5f5; vertical-align:top"
        rows="200"
        value="#{statusResultOverview.statusResultOverviewReport}"
        var="statusOverview"
        rendered="#{!empty statusResultOverview.statusResultOverviewReport}">


        <f:facet name="header">
            <rich:columnGroup>
                <h:column>
                    <h:outputText styleClass="headerText" value="Job Number" />
                </h:column>
                <h:column>
                    <h:outputText styleClass="headerText" value="Entity" />
                </h:column>
                <h:column>
                    <h:outputText styleClass="headerText" value="#{statusOverview.resultOverviewData.rqoRiskDate}" />
                </h:column>
            </rich:columnGroup>
        </f:facet>

        <h:column>
            #{statusOverview.resultOverviewData.jobNumber} 
        </h:column>
        <h:column>
            #{statusOverview.resultOverviewData.rqoEntity} 
        </h:column>
        <h:column>
            #{statusOverview.resultOverviewData.rqoCountOfRd} 
        </h:column>
    </rich:dataTable>    

There are no errors or log messages or whatsoever...

..any help appreciated!

Thanks & Cheers, Axel

There´s only one header and there is an undefinied amount of rows.
How should it know which one to pick for the header value?

Obtain it from #{statusResultOverview} or from some resource bundle.

Hello Bauke,

okaaaay - there are some lessons learnd out of this:

1.) My predecessor (the one, from whom I inherited the GUI I'm currently trying to change) wasn't a JSF expert, either.
2.) Check syntax before asking, Doh!
3.) (Oh, my!)

Mea maxima culpa - sorry for bothering you with this!

Thanks & cheers, Axel

P.S.: Ripleys believe it or don't: The displayed code works as long as you do not try to apply dynamic values to the headers...

Hi all,

ok, 2nd try - with no success...

    <rich:dataTable
        onRowMouseOver="this.style.backgroundColor='#FFFFFF'"
        onRowMouseOut="this.style.backgroundColor='#F5F5F5'"
        width="90%"
        id="statusResultOverviewTable"
        style="background-color: #f5f5f5; vertical-align:top"
        rows="0"
        value="#{statusResultOverview.statusResultOverviewReport}"
        var="statusOverview"
        rendered="#{!empty statusResultOverview.statusResultOverviewReport}">

        <f:facet name="header">
            <h:outputText value="Overview errorcounts over riskdays" />
        </f:facet>

        <h:column>
            <f:facet name="header">
                <h:outputText value="Job Number" />
            </f:facet>
            <h:outputText value="#{statusOverview.resultOverviewData.jobNumber}"></h:outputText>
        </h:column>
        <h:column>
            <f:facet name="header">
                <h:outputText value="Entity" />
            </f:facet>
            <h:outputText value="#{statusOverview.resultOverviewData.rqoEntity}"></h:outputText>
        </h:column>
        <h:column>
            <f:facet name="header">
                <h:outputText value="#{statusOverview.resultOverviewData.rqoRiskDate}" />
            </f:facet>
            <h:outputText value="#{statusOverview.resultOverviewData.rqoCountOfRd}"></h:outputText>
        </h:column>

    </rich:dataTable>
    

Problem resides - the header columns are still left blank (however, when I add some strings around the member these are displayed correctly...)

Another thing: I get errors all around this GUI when accessing a dataTable variable:

05.02.2009 13:40:03 DEBUG [org.apache.myfaces.el.VariableResolverImpl] Variable 'statusOverview' could not be resolved.

I tried to find out, where these come from, but the data object is filled correctly and the content is displayed correctly, too - the var is only referenced within the dataTable - I have no clue where this does come from...

Thanks & cheers, Axel

Hi all,

found the problem..

I tried to display a list in a single field output...

Works now.
