Render Apex:Column the Header goes away?? Help

Hi my header name goes away when I render the column but the value comes up???

 

<apex:column rendered="{!dd.TermD='9.2'}">
                        <apex:facet name="header">Subject Area</apex:facet>
                        <apex:outputText value="{!dd.Subject}"/>
</apex:column>

did you try it this way?
 
 
 
<apex:column rendered="{!dd.TermD='9.2'}" headerValue = "Subject Area" >
     <apex:outputText value="{!dd.Subject}"/>
</apex:column>

This problem comes in play when the rendered attribute used in apex:column is based on a condition which uses the var property.

e.g. When I use following code the header disappears,because my rendered attribute refers to var property
 

<apex:pageblockTable value="{!myList}" var="record">                           
	<apex:column rendered="{!IF(record.Id != null,true,false)}">
		<apex:facet name="header">
			My Header
		</apex:facet> 
		Some content
	</apex:column>
</apex:pageblockTable>


However, when I remove the var property from rendered attribute, it works fine.

Like this,
 

<apex:pageblockTable value="{!myList}" var="record">                           
	<apex:column rendered="{!IF(showColumn != null,true,false)}">
		<apex:facet name="header">
			My Header
		</apex:facet> 
		Some content
	</apex:column>
</apex:pageblockTable>


Basically, inidividual rows can be rendered using var property but header cannot be. Hope this helps!

Thanks,
Prem

If you add another statement in your render to check if there is an ID the headers should appear.

rendered="{!OR(dd.TermD='9.2',id=''),true,false}"

This checks to see if there is an ID in the field (which there is not in a header field) and displays the data

Hope this helps?
