ullright sfForm / object property injection problem

ullright problem:

• ullright supports to inject id and other properties of the base object as value into the widget
  • array('value' = $nativeFieldValue, 'id' = $objectPrimaryKey)
• only ullWidgets support this array format
• this "injection" occurs during default setting in the form construction
• Problem:
  • when posting the form, the post values are used which don't include the array format anymore
  • these post values are used in sfForm::bind()
  • this does not seem to be a problem when the form is saved.
  • but in case of validation errors we have a problem
  • widgets are re-rendered - widgets which depends on the base object 'id' (or other properties) fail because of the missing array format / 'id' injection
• More problems
  • When we merge the array format into the tainted/post values form saving fails, because it can not handle the array format
  • sfForm and associated classes do not allow to set the value of a field after binding the form and failing validation

 Conclusion: formfields better be native, nested or such
