rich:dataTable how to print column headers multiple times

[cavinator]

Hi,

Is there a way to reprint column headers before every single records in <rich:dataTable> ?

The senario is that i have <rich:dataTable> that display Travel Log records.  Right below each Travel Log record I display Travel legs using <rich:subTable>.  To easily view and separate Travel Log and the previous Travel Leg records I want to reprint the Travel Log headers.  Example of the code is below.

<rich:dataTable id="travelLog" var="_travelLog"

...

    <rich:column>

         <f:facet name="header">Travel Log Name</f:facet>

         <h:outputText value="#{_travelLog.name}"/>       

    </rich:column>

...

     <rich:subTable id="travelLeg" value="_travelLeg"

     ...

         <rich:column>

         <f:facet name="header">Travel From</f.facet>

         <h:outputText value="#{_travelLeg.fromLocation}"/>

         </rich:column>

     ...

     </rich:subTable>

...

</rich:dataTable>

Thank you for your help,

Cavin

so the header should appear above every subtable columns? I checked under 3.3.3 and wortks fine for me.

yes and that is the version i have too.  Currently, my temporary solution is to have <ui:repeat> wrap around <rich:dataTable> as shown below.  Would you show me your solution?

<ui:repeat value="{_travelLogs}" var="_log"> <!-- get a list of all the travel logs -->

     <rich:dataTable value="{ get one record of travel log at a time feeded by _log}  var="_travelLog" ...>

        ...

     <rich:subTable id="travelLeg" value="_travelLog.travelLegs"

     ...

     </rich:subTable>

    </rich:dataTable>    

</ui:repeat>

thank you,

Cavin

Thank you Ilya,  but you missed understood me.  I want to reprint the headings from the rich:dataTable.  Assumed the headings in your rich:dataTable is not "Meals", "Hotels", and "Transport". but one column call "Location".  I want to print that heading "Location" above "San Jose" and right ablove "Seattle".  Everything else keep the same (ie. the rich:subtable still have the heading "day", "meals", "hotels" and "transport").

Thank you,

Cavin
