Hi!
I changed it to:

class EditEntry(layout.FormLayoutSupport, form.EditForm):
    fields = field.Fields(IBlogEntry).select("title", "content") 

but which doesn't change the error. This is the interface I get the fields 
from:

class IBlogEntry(IContainer):
    """Interface for blog entry objects."""
    contains(IBlogComment)
    
    title = TextLine(
        title = _(u"Blog entry title"),
        description = _(u"Blog entry title."),
        default = u"",
        required = True)

    content = Text(
        title = _(u"Blog entry content"),
        description = _(u"Blog entry content."),
        default = u"",
        required = True) 

    inputType = Choice(
        title = _(u"Type of input"),
        description = _(u"Specify the input type"),
        required = True,
        default = u"reStructeredText",
        values = [u"reStructeredText", u"HTML"] )
