s:fragment in dataTable

[tony.herstell1]

given :

<h:dataTable var="eachDisplayableCategory"
 value="#{displayableCategorySet}"
 rendered="#{displayableCategorySet.rowCount>0}">

<h:column>
<f:facet name="header">
 <h:outputText value="#{messages.category_name}" />
</f:facet>
<h:outputText value="Head: #{eachDisplayableCategory.head} - " />
<h:outputText value="Displayed: #{eachDisplayableCategory.displayed} - " />
<h:outputText value="Selected: #{eachDisplayableCategory.selected} - " />
<h:outputText value="Parenting: #{eachDisplayableCategory.parenting} - " />
<h:outputText value="Refined: #{eachDisplayableCategory.refined} - "/>
<h:outputText value="Name: #{eachDisplayableCategory.immutableCategory.nameKey}"/>
</h:column>

 <s:fragment rendered="#{eachDisplayableCategory.displayed}">

 <h:column>

The last fragment, that comes before a <h:column> causes the <h:column> to not be rendered in a dataTable. IS THIS A BUG?

Also.. it appears that not providing a <h:column> at all; causes no text to be display (This one I can appreciate - even though it took hours to find it!).. a useful message from JSF saying NO Columns would have been nice!

h:column must be a direct child of h:dataTable

Could this be added to the manual?
I put fragemnts round a LOT of stuff... and this is hell of a gotcha as there is NO clue why stuff just aint appearing!
JSF kindly dont put out any mesasges...

Not really, this is just JSF ;) Better errors/warnings for this kind of thing are on the cards for JSF 2.

Well I hope that this post helps someone who got as frustrated as myself.

tis like second nature to do this:

 <h:column>
 <s:fragment rendered="#{eachDisplayableCategory.refined}">
 <s:fragment
 rendered="#{eachDisplayableCategory.immutableCategory.parent == null}">
 <h:selectBooleanCheckbox
 value="#{eachDisplayableCategory.selected}" disabled="true" />
 </s:fragment>
 <s:fragment
 rendered="#{eachDisplayableCategory.immutableCategory.parent != null}">
 <h:selectBooleanCheckbox
 value="#{eachDisplayableCategory.selected}" />
 </s:fragment>
 </s:fragment>
 <s:fragment rendered="#{eachDisplayableCategory.refined}">
 <h:selectBooleanCheckbox
 value="#{eachDisplayableCategory.selected}" disabled="true" />
 </s:fragment>
 </h:column>

its only a small set to add <s:fragment> outside the column!!! and you have NO IDEA why suddenly nothing happens...
