That was quite helpful. I am on the right track and I even managed to 
get
most of my subcomponents bound correctly.

However, the only thing left is the <a jwcid="linkColumn"> that sorts 
the
table differently. It seems that I got the parameters up correctly 
(phew!)
but the listener is left to be converted and I have not the slightest 
clue
on how to do this:

<component id="linkColumn" type="DirectLink">

     <binding name="listener" expression="listeners.columnSelected"/>
     <binding name="parameters" expression="new java.lang.Object[] { new 
org.apache.tapestry.util.ComponentAddress(tableModelSource), 
tableColumn.columnName }"/>

</component>

What should I put in there to replace listeners.columnSelected ?

Thanks,
Andreas Pardeike
