[Catalyst] FormBuilder missing disabled fields after submit

[Ulrich Leodolter]

hi,

i am using Catalyst::Plugin::FormBuilder for my input forms.

optionally i need to make some input fields readonly (not hidden)
so i disabled the fields (disabled => 1)
the input form looks ok und the fields are disabled (actually readonly)

when i submit the form the disabled fields are removed (looks like 
CGI::FormBuilder deletes them)
but i need them to access the database.

how can i access disabled form fields after submit?
(maybe this is an CGI::FormBuilder problem/issue)

thanks for any help
