Comment 1 for bug 142590

Calling manage_edit on a DTMLDocument sometimes barfs with

Traceback (innermost last):

AttributeError: read

For instance, from a python script

  bodyStr = string.replace( bodyStr, '\015\012\015\012', '<br>\015\012<br>\015\012' )
  context['body_contents'].manage_edit( data=bodyStr, title='Body Contents' )

For plain text, the call is fine - if the text contains markup, it fails

Relevant line (77) in DTMLDocumemt.py is

  if type(data) is not type(''): data=data.read()

For data containing markup, type(data) is resolving as <type instance> which presumably has no attribute read.

Workaround is to coerce the variable to a string with

  context['body_contents'].manage_edit( data=str(bodyStr), title='Body Contents' )
