I have a fillout-form with 2 buttons in which users have to review

Else, he would submit his data.
Now, I thougt i can check for the runmode ('save') given in the 
review-form by a hidden-field and set the correct runmode.

sub cgiapp_prerun {
     my $self = shift;
     if( $self->get_current_runmode() eq 'save' ){
         my $q = $self->query();
         if( defined($q->param('back')) ){

#print STDERR $self->get_current_runmode();
             $q->param(-name=>'error', -value=>1);
         }
     }
} # /cgiapp_prerun
This doesn't work.
Anytime the button 'back' gets clicked, I saw the fillout-form AND 
the review-form.
The output to STDERR returns 'save', although I set it to 'showForm'...

What is the name of your submit button? Is it 'back' or is that just 
the value? Did you make sure that your call to prerun_mode is getting 
run? Put in a debug print/die/warn statment inside the if( 
defined($q->param('back')) ) block just to make sure.

The button is named back, its value is "<< zur�ck": <input type="submit" 
name="back" value="&lt;&lt; zur&uuml;ck" />
print STDERR $self->get_current_runmode(); returns 'save', so the sub 
cgiapp_prerun is called.
I'm sorry. I was just looking through the code and the prerun_mode() 
doesn't actually change the value of the current run mode. It saves it 
for changing. The change doesn't actually take place until after your 
cgiapp_prerun has finished. Instead of catching the runmode from 
get_current_runmode() while inside of your prerun, use prerun_runmode().

So instead of
    print STDERR $self->get_current_runmode();
you should use
    print STDERR $self->prerun_runmode();
I don't know if this is an intended feature or not. I would seem to me 
that prerun_runmode should change the current_runmode, but you may have 
to complain loudly to get this changed since the above changes would work.
