[Catalyst] filling fields through FromBuilder dynamically

[rahed]

Hello,

I render forms in the TT template with [% FormBuilder.render %]. The
forms are defined in file.fb.
I would like to dynamically change one of the predefined values
(date), something like this:

[% FOREACH field IN formbuilder.fields %]
   [% IF field.name == 'my_name' %]
      [% field.value == 'MY_DATE' %]
   [% END %]
[% END %]

But this doesn't work because of FormBuilder.render.
I'd like to keep my external source file to generate the forms. Is
there any way out?

Thank you.
