[html-formfu] custom ExtJS element

[Moritz Onken]

Hi Alex,


did you try to just use a Text element?

  - elements:
      - type: Text
        attrs:
          xtype: itemselector


This should do it. If you want to create a custom ExtJS element you  
have to create both a HTML::FormFu::Element::ExtJS::ItemSelector and a  
HTML::FormFu::ExtJS::Element::ItemSelector.

The elements in the HTML::FormFu::ExtJS::Element namespace are not  
objects in the OO sense. They just provide a "render" method which is  
used by ::ExtJS to render a HTML::FormFu::Element.

cheers,

moritz
