This is really weird. Somehow Tapestry thinks that the actionlink is referring to a component placed
on another page than the one that is rendering. And since it thinks the containing page is the index
page, it converts the page name to the empty string "" which is not allowed as a value for a paramater.
I'm confused.

On first look I can't see what's wrong here. Could you please post
exactly where this happens (the error report should give you the
name of the component that is in error and a line number inside your
template).

Hello,
I am having difficulties understand why the followinf piece of
code gives me
the error "Parameter value was null or contained only
whitespace". If I
remove <t:actionlink> from the <t:if> or replace it with for example
<t:pagelink>, then the error does not appear. If I move
<t:actionlink>
outside <t:if> it works also, but I need to have <t:actionlink>
in <t:if>
obviously.
Please advise.
