SV: [Catalyst] Problem with TT view and form.field

[Peter Sørensen]

Hi Jason,

Thanks for looking into the problem. I have tried your
suggested syntax but still no output.

I can access the information with:

	form.field.3.label

where 3 is the index in the array but this is not what I want.
I want to be able to address the content using the name of the field.

regards

Peter

These are actually exactly the same method in CGI::FormBuilder, which
says:

*param  = \&field;
*params = \&field;
*fields = \&field;
sub field {

The source for CGI::FormBuilder says that field, if called without an argument, will return "an array of the names in list context, and a hashref of name/value pairs in a scalar context".  This is problematic behavior with TT, as TT always uses a list context, so form.fields and form.field are both going to return an array of field names.

Looking at the source though, it looks like you should be able to get at them this way:

[% form.field( 'firstname' ).label %]
