[Archetypes-users] ImageField, AttributeStorage, and Max. Recursion Depth Error

[shelon23 <she...@di...>]

Hi,

I am trying to create a custom AT contenttype in Plone 3.3.3 which contains
an ImageField called 'memberimage'. According to
http://plone.org/documentation/manual/developer-manual/archetypes/fields/fields-reference,
the ImageField allows to pass a parameter 'sizes' to it, so that later on an
image should be accessible in different sizes using the URLs
obj/memberimage, obj/memberimage_thumb, etc. (as specified by 'sizes'). 

This doesn't work though (obj/memberimage works but obj/memberimage_mini
doesn't) based on the field definition which was generated by paster, and I
changed the storage to AttributeStorage (as is indicated in the
documentation) like in

    atapi.ImageField(
        'memberimage',
        # storage=atapi.AnnotationStorage(), # paster version
        storage=atapi.AttributeStorage(), # results in "max recursion depth
exceeded" error
        widget=atapi.ImageWidget(
            label=_(u"New Field"),
            description=_(u"Field description"),
        ),
        validators=('isNonEmptyFile'),
        original_size=(600,600),
        sizes={ 'mini' : (80,80),
                'normal' : (200,200),
                'big' : (300,300),
                'maxi' : (500,500)},
    ),


This results in an exception when I try to access the object:

   - __traceback_info__: ('memberimage', <TTMemberImage at
tt_member_image.2010-01-23.8138248069>, {'field': <Field
memberimage(image:rw)>})
  Module Products.Archetypes.Storage, line 96, in get
  Module Products.Archetypes.utils, line 808, in shasattr
  Module Products.Archetypes.fieldproperty, line 101, in __get__
  Module Products.Archetypes.Field, line 997, in get
  Module Products.Archetypes.Field, line 709, in get
   - __traceback_info__: ('memberimage', <TTMemberImage at
tt_member_image.2010-01-23.8138248069>, {'field': <Field
memberimage(image:rw)>})
RuntimeError: maximum recursion depth exceeded

How can I work around this? How do I get the image rescaling to work for an
ImageField (not an ATImage)?

Thanks for your help!
