Fieldsets HTML output escaped after Sprox, ToscaWidgets and tw.forms upgrade

[diegows]

I've been using TableFieldSet? without any problem until Sprox, Toscawidgets and tw.forms upgrade (0.6.1, 0.9.6 and 0.9.6). After upgrade, TableFieldSet?().display() shows the children fields escaped.

I'm using TG2.

Steps to reproduce:

virtualenv --no-site-packages tg2envirtualenv --no-site-packages tg2env easy_install -i  http://www.turbogears.org/2.0/downloads/current/index tg.devtools easy_install zope.sqlalchemy easy_install Babel easy_install Catwalk paster quickstart testproject cd testproject paster shell

from tw.forms import TableFieldSet?, TextField? fs = [ TextField?('one'), TextField?('two') ] f = TableFieldSet?('testfieldset', children = fs) print f.display()

I've downgrade Sprox, tw.forms and ToscaWidgets? to previous version and works again.

Additional info:

The output is correct using python directly, without paster shell.

from tw.forms import TableFieldSet, TextField
fs = [ TextField?('one'), TextField?('two') ] 
f = TableFieldSet?('testfieldset', children = fs)
print f.display()

 http://toscawidgets.org/trac/tw.forms/ticket/32 is related to this bug.

I've installed tw.forms from trunk (508cfe7eb5b1) and works.
