Using rendered tag with rich:column

[abhilashkollipara]

Hi,

I am using rich:dataTable to display my data. I have a requirement where "column 1" should be displayed if the respective rendered tag for the column is true and "column 2" should be displayed if the the respective render tag is true. At any point of time only one of the renderer is true.

What i have tried is:

1.

<rich:column>

<f:facet name="header">

<h:panelGroup>

          <h:outputText value="Grade" rendered="#{record.gradingSystem}"/>

          <h:outputText value="Marks" rendered="#{record.average}"/>

</h:panelGroup>

</f:facet>

          <h:outputText value="#{record.grade}" rendered="#{record.gradingSystem}"/>

          <h:outputText value="#{record.score}" rendered="#{record.average}">

           <f:convertNumber maxFractionDigits="2"/>

          </h:outputText>

</rich:column>

when i use the above code none of the headers is displayed / empty header is displayed for the column, but data is displayed correct.

**Please see atachment 1 for the output.

2.

<rich:column rendered="#{record.gradingSystem}">

<f:facet name="header">

          <h:outputText value="Grade"/>

</f:facet>

          <h:outputText value="#{record.grade}"/>

</rich:column>

<rich:column rendered="#{record.average}">

<f:facet name="header">

          <h:outputText value="Marks"/>

</f:facet>

          <h:outputText value="#{record.score}">

           <f:convertNumber maxFractionDigits="2"/>

          </h:outputText>

</rich:column>

when i use the above code next column header is displayed for this data and the last column appears with out any header.

**Please see atachment 2 for the output.

Please help me resolve this.

Thanks & Regards,

Abhilash.

Hi Abhilash,

you cannot use a row-Variable (your variable record) to define rendered-Status, because JSF first evaluates the column definition and then it renders it (for example you have two rows, one would render true, the other false, what would you expect...?). Just use the "arent" of your record (your controller or something like that).

Best regards,

Mark
