HI Jason,

Is this option available with cocoon 2.1.5*?
Because we are getting the following error=0D

What about it is not working?  Your example code did not include any=0D
fd:submit widgets, so it's not clear what you're trying to do.

Are you able to use fd:group in other places, i.e. not within fd:union?=0D
  If it doesn't work elsewhere either, then my guess is your xconf is=0D
missing the component definition for the group widget (perhaps as the=0D
result of upgrading from a release before fd:group was added?).  Check=0D
that your cocoon.xconf contains the following:

   <!--+
       | forms's FormManager component
       +-->
   <forms-formmanager>
     <widgets>
       ...
       <widget name=3D"group"=0D
src=3D"org.apache.cocoon.forms.formmodel.GroupDefinitionBuilder"/>
       ...
     </widgets>
   </forms-formmanager>
