[Zope3-Users] Strange occurrences whilst playing with Mutable Schemas in 3.3b1

[Graham Stratton]

Playing with the ZMI in 3.3b1 I came across a few issues, I'm not sure 
whether any of them are bugs:

If I create a mutable schema, I can't add Text fields, though I can add 
Int fields.  The error is:

ComponentLookupError: ((<zope.schema._bootstrapfields.Field object at 
0x22a5910>, <zope.publisher.browser.BrowserRequest instance 
URL=http://stratton:8080/testschema2/@@+/action.html>), <InterfaceClass 
zope.app.form.interfaces.IInputWidget>, u'')


Wondering what I'd done to deserve this error, I played a bit with the 
registrations, thinking that maybe I had to register the utility before 
it would work.

If I register the schema as a utility using a different name to its 
object name then I get an 'object not found' when trying to add a new 
field since the adding redirect goes to the registered name instead of 
the object name.

Finally, if I register the utility twice and then remove the first 
registration, then the edit page heads with Schema Name: <schema not 
activated>.

I hope I'm not wasting everyone's time with these points.

Regards,

Graham
