Thank You Ron. I digged deeper on this before going to sleep and came
to the same conlusion.. I also figured out the problem with
HttpSessionAttributeListener. It was ofcouse my silly casting error
that caused ClassCastException be thrown inside the attribute listener
method.
However, is this a bug in Tapestry? It seems to me like Tapestry is
catching exceptions in SessionAttributeListener and not bubbling them
up. This has caused me all the grief to begin with. Shouldn't the
Tapestry throw back the exception so that I know what's going on?
Once I corrected my listener method I saw the key Tapestry is using to
map all attributes and it all became obvious.
