[Erp5-dev] Accessing the object from external validator of the workflow action form

[Jacek Medrzycki]

I'm launching the field's External Validator from the action form of a
workflow transition.

Is it possible to access - from the External Validator - the object
which is subject to the workflow transition?

Probably, you are not using the right tool. If you need to validate data
during or before a workflow transition, you should use contraints, not
fields or field validators.

Field validators are only there to help users enter information. Field
validators should be used to validate user entries. They should not be
used to validate document data.

It is exactly what they are used for - I am validating _user_input_ on a
workflow action dialog (a customized and more complex one, with
additional workflow variables to be entered by the user). However, to
check validity of this input, I need to access the object.
I can extract the object from the request, but is there a more elegant
solution?

Sorry, I understand now. Thanks. I will try to get an answer.

I only know those two solutions:

context.getPortalObject().restrictedTraverse(request.get('object_path'))
context.aq_parent.aq_parent.aq_parent
