Unauthorized Error while rendering email template

[cwx-hannoschulz]

After the security update 1.6.7 the three methods getBody_pre, getBody_post and getBody_footer are no longer callable from mail template.

How to Reproduce:

• Install Plone 3.3 via Unified Installer
• Create a PloneFormGen default form and add some text in mailadapter fields "Body (prepended)", "Body (appended)" and "Body (signature)"
• Send the form

The fields missing in the mail, cause of the "| nothing" in the template field. I've debugged this to the changed security declaration in version 1.6.7.

It seems that this change was introduced as as Backport docstring/setPrivate fixes from 1.7.9 in https://github.com/smcmahon/Products.PloneFormGen/commit/51695f64d081bb57c62439163e12ddfe0eea6ecb, but there is no exact match for it in 1.7.9.

bobo_traverse-patch in https://github.com/smcmahon/Products.PloneFormGen/commit/de053133678b07e2fedfa44fa59ba28350fc76af looks like the closest match.

Would it be correct to revert declarePrivate from getBody_pre, getBody_post and getBody_footer and add bobo_traverse-patch from https://github.com/smcmahon/Products.PloneFormGen/commit/de053133678b07e2fedfa44fa59ba28350fc76af? Or was there some other reason why the backport was so much different from fixes in 1.7.9?
