[Product-Developers] Need Help Diagnosing an Error Message

Mark Phillips mark at phillipsmarketing.biz
Wed Dec 19 00:30:47 UTC 2007 

I am using 
Plone 2.5.2, 
CMF-1.6.4, 
Zope (Zope 2.9.7-final, python 2.4.4, linux2), 
Five 1.4.2, 
Python 2.4.4 (#2, Aug 16 2007, 02:03:40) [GCC 4.1.3 20070812
(prerelease) (Debian 4.1.2-15)], 
PIL 1.1.6
membrane 1.0
remember 1.0b1

I have the following code in my ahsremember.py product (see attached
file). I am following the sampleremember product.

    atapi.TextField(
            'PrivacyPolicy',
            widget=atapi.TextAreaWidget(
                label='The privacy policy for this site',
                description='The privacy policy for this site',
                rows='10',
                cols='40'),
            regfield=1,
            required=True,
            #mode='r',
            default_content_type='text/html',
            accessor="PrivacyPolicy",
                ),
 and

    security.declarePublic('getPrivacyPolicy')
    def getPrivacyPolicy(self):
        policy = "The privacy policy......"
        return policy

If I comment out the accessor="PrivacyPolicy" in the TextField
definition above, there is no error and the text field is displayed.
However, as written, I get the following error. I must be making a basic
archetypes usage error, but I cannot find any documentation to figure it
out. The error message are not much help to me. 

Thanks for any suggestions you may have.

Mark
