[Catalyst] jQuery gotcha

Found a change in the latest jQuery (1.4.1) from the previous release I use=
d (1.3.2) that affected  a Catalyst app of mine.=A0 Regarding form field su=
bmissions, jQuery now submits multiple checkbox (or select) values with the=
 variable name followed by the array "[]" brackets (probably to appease PHP=
).=A0 I had a problem with a previous working app and used firebug to look =
at my JSON post and found the brackets.

What used to be:

=A0=A0=A0 tags=A0 25
=A0=A0=A0 tags=A0 18
=A0=A0=A0 tags=A0 10

is now:

=A0=A0=A0 tags[]=A0 25
=A0=A0=A0 tags[]=A0 18
=A0=A0=A0 tags[]=A0 10


=A0=A0=A0 my $tags =3D $c->request->params->{tags};


=A0=A0=A0 my $tags =3D $c->request->params->{'tags[]'};

corrected it (the quotes are needed).=A0 Hope this is helpful.

This was my first post, been reading forums for awhile and want to thank al=
l of you for the skill and knowledge you offer.=A0 I thank you for the foru=
m posts, blogs, calendars and books.=A0 I am not a trained programmer, but =
with your help I have been able to build a few production Catalyst apps.
