CGI::Application uses CGI.pm behind the scenes so if you don't find something in the docs look there as well. In particular I think the section on MIXING POST AND URL PARAMETERS is what you need.
Based on that information, you can write a function like this:
# Called before CGI::App dispatches to a runmode
sub cgiapp_prerun {
my ($self) = @_;
# $self->mode_param so we don't have to go back and change this if
+ we
# ever decide to use something other than rm
if ($self->query->url_param($self->mode_param)) {
# prerun_mode lets you change CGI::Apps notion of the current
+runmode
$self->prerun_mode($self->query->url_param($self->mode_param))
+;
}
return;
}
Actually thats kind of overkill. A simpler solution would be to remove rm=mode2 from the forms action and include a hidden field called 'rm' with value 'mode2' in the form body instead.
Also for debugging look into CGI::Application::Plugin::DebugScreen and CGI::Application::Plugin::DevPopup.
