plone - 'LocationError' on custom field after using a custom importer to import some dexterity based content types -

i've created importer custom dexterity content type. imports types fine, 'locationerror' when try view newly imported content following traceback:

interestingly visiting url of content type followed /edit works , after saving changes view works.

the "output" portion of locationerror message suggests having trouble rendering richtext field. possible initialized richtext field other richtextvalue?

you cannot assign string richtext field. requires richtextvalue:

from plone.app.textfield.value import richtextvalue context.body = richtextvalue(u"your text here, in html") 

see dexterity developer's manual section on richtextvalue details. allows set input , output mime types text.
