When I make a custom attribute as a checkbox (I've tried to add it on the embed tag) the value is not checked when it should. Seems like it doesn't save the value correctly either so I cant use it in a template.

Added custom attributes in OE as a feature request to eZ in 2005, and I'm very happy it is in the new version. Seems to work very good for other types (text).

Steps to reproduce

content.ini.append:
[embed]
CustomAttributes[]=test

ezoe_attributes.ini.append
[CustomAttribute_test]
Type=checkbox

The checkbox shows up fine, but if I check it or not it still doesnt have a value in the template not is it showing up correctly if i edit the object again.

Using version in eZP 4.1.3
