Doco Update

[tony.herstell1]

I KEEP falling over the problem that if you don't have a <rich:column> after a <rich:dataTable> then not only does the stuff afterwards not appear but it doesn't even get processed.
Can be very confusing!!

Perhaps a small note (gotcha) in the doco in the datatable section...

Please pardon me, but it seems I can't get you right :( Could you please somehow illustrate the issue?

Try taking the rich:column out from a rich:dataTable and see what happens...

Everything is not rendered after where the rich:column tag was.

You get no warning messages at all; it just doesn't render...

e.g.

rich:dataTable
rich:column
<output text blah blah>
rich:column
rich:dataTable

take out (or foget to put in) the rich:column and you get no <output text blah blah> renderd.

Some components require only particular set of components to be their children. Like h:dataTable, h:selectOneMenu and so on. Do those standard components warn when you put an outputText there?

[tony.herstell1]

Not that I have seen!

Which is why I sit scratching my head for ages till I figure it its NOT me and its actually not being rendered...

<a4j:outputPanel id="allocation_days_with_bookings" layout="none" ajaxRendered="true">
 <a4j:outputPanel id="allocation_days_with_bookings_panel"
 rendered="#{bookingController.reason == 'ONE_HOUR_PRIVATE' || bookingController.reason == 'ONE_HOUR_OPEN'}">

 <h:panelGrid class="left" id="allocation_days_heading"
 rendered="#{not empty bookingController.getArenaRequiredForOneHourBooking()}">
 <h:outputText class="sub3_title" id="select_date_title"
 value="#{messages.allocation_select_date}" />
 </h:panelGrid>

 <s:fragment id="allocation_days"
 rendered="#{not empty bookingController.getArenaRequiredForOneHourBooking()}">

 <rich:dataGrid var="allocEachResourceKind"
 value="#{bookingController.getResourcesRequiredForOneHourBooking()}" columns="2" elements="2">
 <f:facet name="header">
 <h:outputText value="Allocations"></h:outputText>
 </f:facet>
 <rich:panel>
 <f:facet name="header">
 <h:outputText id="allocation_resource_kind"
 value="#{messages[allocEachResourceKind.inlLabel]}" />
 </f:facet>
 <h:panelGrid columns="2">
 <rich:dataTable var="dayForResourceKind"
 value="#{resourceAllocationController.getDays(allocEachResourceKind, bookingController.getBookingDateRequired(), 1)}">

 <rich:column>

 <rich:dataTable var="daySlotForResourceKind" value="#{dayForResourceKind.daySlots}"
 width="100%" border="0">
 <f:facet name="header">
 <rich:columnGroup>
 <rich:column colspan="2">
 <h:outputText value="#{dayForResourceKind.date.time}">
 <s:convertDateTime type="date" dateStyle="full" />
 </h:outputText>
 </rich:column>

blah blah

When you are THIS far down the tree and things dont appear you can imagine it takes a bit of debugging to find out why...


nb.. you have to do the double aj4:output panel or else this part of the page does not update itself either... odd...
