Hi Groovie,
rendered works fine on tc:column.
but you can't use the row variable for this, because the rendering of
a column can't depend on the row.
Or how would you expect e.g. exel to render a column in one row but
not in the next?
I thing what you want is to render different content, row dependent,
in the same column? Than you should use the rendered not on the
column but on the out.
<tc:column label="...">
<tc:panel>
<tc:out rendered="#{currentLine.booleanBeanAttrib1}" value="..."/>
<tc:out rendered="#{currentLine.booleanBeanAttrib2}" value="..."/>
<tc:out rendered="#{currentLine.booleanBeanAttrib3}" value="..."/>
</tc:panel>
</tc:column>
The panel surrounding the tc:out is not needed, but without you will
get a warning about layout problems in the log file.
Regards,
Volker
