Hi Giacomo, thanks for your reply.

I am just trying to work out where to do all the jobs the Crudlet TagLib
does, if they were not going to be done in a TagLib (just trying to work
out if it is possible/desirable)

Something that allows me to map out (then control) the progress of my webApp
 	what needs to happen to "get here"
	where I am allowed to go next,
	what is the scope of the objects we are manipulating.

For instance if I could use something like a flo map to say, when you come
here I'll make you a new object that you are going to fill in over the next
couple of pages, then commit the object to the Space, and throw it away (if
you take this exit), unless of course you did not fill it in properly, or
wandered off, in which case, when you come back you can carry on filling it
in as long as you are within the session timeout.

Just a thought ... Now Actions have got xml configuration files, are they
going to be 'the new XSP'? ie. it's only a short step before people want
them compiled on the fly ... ?

Phew! ;)

Oh dear, Donald simultaneously suggested it too.

An Interface initially developed for Objects fed to XSP, has toDOM and
toSAX methods.

We got Beans, we update them, (easily handled by an Action) we output them
as XML (give it to the StyleSheet as an XML Fragment and let the XSL Author
take the bits they want).

Sorry if my questions appear daft :)
