in reply to Toolkit Template undef error debugging

Something in my data has changed, but I'm not sure what, or where to look.

The obvious place to look is your revision control system. It allows you to go back to previous versions, and compare differences.

If you don't use one, start using one now - it's a very useful debugging tool, takes the fear of breaking stuff when you change things, and is also otherwise generally useful.

Perl 6 - links to (nearly) everything that is Perl 6.

    Indeed, I learned early to use a revision control system. The code itself hasn't changed, but there was something odd with this one set of data.

    As it turns out, it was a faulty assumption. I assumed that the resident state data would be present. When it wasn't, $stash->set( 'resident', undef ) occurred inside the [% PERL %] block, giving me my strange error. I'm a little disappointed that TT didn't give me a better error message as to where this was happening.
