Dynamic text inside datatable header

[priestex]

Hi,

I have a simple datatable where I am trying to use some dynamic text as the header:

1. <rich:dataTable value="#{reportTableView.rowList}" var="row">
2. <rich:column>
3. <f:facet name="header">
4. <h:outputText value="#{row.cellList[0].column.columnHeader}"/>
5. </f:facet>
6. <h:outputText value="#{row.cellList[0].displayValue}"/>
7. </rich:column>
8.</rich:dataTable>

A constant value like the string 'ABC' as the value of outputtext on line 4 works fine.
The dynamic value #{row.cellList[0].column.columnHeader shows the right value if used on line 6 outputtext.

Is there a way for me to use the dynamic value as the column header?

Thanks

Hello,

You cannot use var request variables defined by dataTable in column's header facet. Var is initialized during table's rows encoding, but facets are rendered before it.

Anyway you case in obscure. Column header is rendered one for whole row. But you want to set name for header related to each data row.

I thought putting it in the header facet meant that it will only get rendered once, for the header.

All the examples online seem to use constants for datatable headers. All I want to do is access some property on my bean instead of using a hard coded string for the header. Is there some way I can do that?

Andrei just wanted to tell you not to use iteration variable. Just use something like

<f:facet name="header">
 <h:outputText value="#{beanName.header1StringProperty}"/>
 </f:facet>

Ok, got that.

Thanks for the help
