[Catalyst] Catalyst::Plugin::HTML::Widget contraint problem

[Alan Humphrey]

I’m trying to use Catalyst::Plugin::HTML::Widget for data validation.  Just 
to try things out I have this in my controller:



$c->widget->constraint->('Email','identification')->message('bad email 
address');



When that line is executed I get the following:



[Tue Jan 17 15:52:59 2006] [catalyst] [error] Caught exception "Couldn't to

I can send along the rest of the stack trace, but this seemed to be the 
relevant bit.



Note that it’s trying to load an empty constraint name.



I tried naming the widget but got the same result:



$c->widget(‘foo’)->constraint->('Email','identification')->message('bad 
email address');



Removing the message likewise had the same result.



Any ideas?  Bug?
