How strange. When I deliberately remove the eventSubmit_doLogin (or
change it to something else,) I get the attached unhandled exception.
However, everything functions as expected when I set it properly - I get
sent back to login.vm if the userID or password is wrong.
Make sure eventSubmit_doLogin is getting set to something. I wish I
could duplicate the propblem. (Also, it appears that turbine has to be
shutdown and restart for it to re-read TR.props)
