It is funny, because SimpleTransform.java assumes that all parameters
are Strings, and casts them to (String) before setting it in the
Stylesheed. Could you repeat the experiment printing the key and value
just before line 177 of SimpleTransform.java?

You will need to use a DynamicURI(request) and add the current
parameters to it. It is tricky, because post parameters cause problems,
and there is no separation of parameters belonging to different
portlets, and you have to code knowledge about the page as a whole. We
are working to find better ways to refer to "internal" URIs, i.e., URIs
used to store ONLY knowledge about the current webapp state.
