Hi Kennedy,

I totally see your point there. Unfortunately it isn't that easy to fix.
Every field has a value and value_xml method which contains the
field's value (default and default_xml are aliases for those methods).
Model::DBIC however sets the value by calling default.

I see two possible ways to fix this. Either we patch model::DBIC to read
a value from the model_config of a field and decide then whether to 
use default or default_xml:

---
  elements:
    - type: Label
      name: first
      model_config:
        is_xml: 1

Or for now you can write your own deflator which can reverse the encoding.
Have a look at HTML::FormFu::Deflator::FormatNumber for an example of
string manipulation.

The best practice for home-made Deflators is to name them like this:

HTML::FormFu::Deflator::MyApp::XMLLabel, so you can use

deflator:
  MyApp::XMLLabel

in the configuration.

I forwarded this mail to the formfu mailing list, which you should 
subscribe to :-)

I can find you on IRC next week so we can discuss about the Catalyst 
tutorial thing and what you have in mind.

Cheers,
