Hello everyone,
I created a custom dexterity field that is called from my IDataManager adapter.
Inside the field setter I noted, that the object being created is an Acquisition.ImplicitAcquisitionWrapper object that fails when calling content.UID().
Code excerpt from plone.dexterity.browser.add:
def create(self, data):
fti = getUtility(IDexterityFTI, name=self.portal_type)
content = createObject(fti.factory)
# Note: The factory may have done this already, but we want to be sure
# that the created type has the right portal type. It is possible
# to re-define a type through the web that uses the factory from an
# existing type, but wants a unique portal_type!
if hasattr(content, '_setPortalTypeName'):
content._setPortalTypeName(fti.getId())
# Acquisition wrap temporarily to satisfy things like vocabularies
# depending on tools
if IAcquirer.providedBy(content):
content = content.__of__(self.container)
_applyChanges(self, content, data, force=True)
for group in self.groups:
_applyChanges(group, content, data, force=True)
---> import pdb; pdb.set_trace()
return aq_base(content)
PDB Session:

My question now:
Can I access the UID from a dexterity field, or do I have to do this code in an IObjectCreated event handler?
Thanks as always for your feedback
