Im not sure if you can find a complete standalone example for this, but I think your problem now is with eval().
Can you copy your stackTrace here? I think you can not do eval( literal == literal), but you could make a function to test that if you wanna use eval and give the function the value of @{symbol} 2010/4/27 Stefan Marconi <stefan.marc...@gmail.com> > Hi Felipe, > > thank you for your reply.
