Doh! I actually misspelled the parameter in my TR.props file. When I
put in the incorrect eventSubmit_ information, I get the login screen
with the message that it couldn't find that button - which is correct.
And when I put in the incorrect user ID or password, I get the login
screen, which is also correct. Not sure what the root of your problem
might be. I've got the following in my login.vm:
<FORM method="POST"
action="$link.setPage("index.vm").setAction("LoginUser")">
And it only goes to index.vm when the Action succeeds. I don't have an
Index class to verify that the user is logged in.
Hmmm....
