[Seaside] [newbie!] syntax errors in framework code while debugging/stepping into (kinda urgent)

Hello Julian,

thank you for the quick answer!!

I checked again when squeak would be stuck (meaning, the
last button on the debugger I pressed is still pressed and I
can't do anything on squeak anymore), and it's when a new
context is created. A real pity that doesn't work, but I'm
really relieved it wasn't my fault.

About the syntax errors: there were more strange ones, so I
took another fresh image and retyped everything and now it
works...perhaps I messed something up with the debugging...

And yes, I read that post, it helped indeed and I'm gonna
show that to my fellow students. :)
I only read here
http://www.swa.hpi.uni-potsdam.de/seaside/tutorial that
render- and redirectContinuations aren't real continuations
anymore (so they're calling them handlers there), so are
those then objects which save some states (only those
variables I told them to save with the states message) in
e.g. a RenderContext, but don't save the whole context
chain/stack? If I press the back button that handler knows
which object's variables should be set to the old values its
got saved in it's RenderContext, sort of like this?

thanks again, have a nice day
