Edit load </dtml-comment>
<tr><td><b>Load from File?</b></td></tr>
<tr><td><form name="form" action="<dtml-var "URL1">/manage_load_file"
method="POST" ENCTYPE="multipart/form-data">
<tr><td><INPUT TYPE="file" NAME="fid" SIZE="50"               /><br>
        &nbsp;<input type="radio" name="ft" value='txt' checked  /> as txt (
repr )<sup><b>*</b></sup>
        &nbsp;<input type="radio" name="ft" value='tbs'          /> as tbs
(pickle)
        &nbsp;<input type="submit"          value=" Load "       />
    </td></tr>
<tr><td></form>&nbsp;</td></tr>

and

 def manage_load_file(self, ft, fid, REQUEST=None):
  """load tabstree from client file, ftype/format: 'tbs'=unpickle,
'txt'=eval"""
  f_type = ft # dunno how to detect filetype, made radio buttons
  file = REQUEST[ 'fid' ]

  if file == None: # code copied, dont understand it myself
   f_head = ''
   f_data = ''
  else:
   f_head = hasattr( file, "headers" ) and file.headers or None
   f_data = (f_head is None) and file or file.read()

  if   f_type == 'tbs':  # a) unpickle/pickle 3 lines
   tmpFile = StringIO(f_data)
   tmpPick = pickle.Unpickler(tmpFile)
   self.tabstree = [] # just to be safe
   self.tabstree = tmpPick.load()

worked fine for me
