I run into this sometimes. The delete method is definitely not getting called
if your warning isn't showing up. First turn on debugging : in your driver
(BeerDB.pm) make a sub:
sub debug {1};
or use the flag in use base Maypole::Application(DEBUG=>1) # check man for
syntax
Debugging should give you more idea where error is via errorl log warnings.
For me i've found this is caused by:
1) delete method not having the exported attribute.
2) user not having permission -- it should if you haven't changed
authentication yet.
3** ) Error before delete method gets called. this is usually a
relationship error or database not in synch with cdbi classes ie column name
different, not there, etc that causes a require to halt before getting to the
delete method for example. This is by far most frustrating problem i have with
maypole error handling because you can break something by changing completely
unrelated code.

After debugging is on you should get better idea what went astray. After
putting warn in method i'm calling, if your using all default stuff, i'm
guessing the problem is yoour relationship declarations in cdbi class or
database differing from declarations in cdbi class.
