Bug Description

This actually applies to any screen where you are Editing a record that has a Binary field on it.

To replicate:

1. FIRSTLY - if you are running the web client from source, DELETE the following two folders:



On my system, these folders had some .pyc files left in them, which python was prioritising over the '' file which was present in the same folder. This lead to much confusion trying to isolate the problem!!

2. In the web client, click the Knowledge button

3. Under 'Documents' on the left hand menu, select 'Documents'

4. If you do not have any 'Binary' documents, create one.

5. Click Edit on the document, do not change anything, then click 'Save'. You should get the following stack trace, generated on the server:

Traceback (most recent call last):
  File "/usr/local/bin/openerp6/server/bin/osv/", line 122, in wrapper
    return f(self, dbname, *args, **kwargs)
  File "/usr/local/bin/openerp6/server/bin/osv/", line 176, in execute
    res = self.execute_cr(cr, uid, obj, method, *args, **kw)
  File "/usr/local/bin/openerp6/server/bin/osv/", line 167, in execute_cr
    return getattr(object, method)(cr, uid, *args, **kw)
  File "/usr/local/bin/openerp6/server/bin/addons/crm_simple/", line 42, in write
    return super(ir_attachment, self).write(cr, uid, ids, vals, context)
  File "/usr/local/bin/openerp6/server/bin/addons/document/", line 230, in write
    result = super(document_file,self).write(cr, uid, ids, vals, context=context)
  File "/usr/local/bin/openerp6/server/bin/addons/base/ir/", line 83, in write
    return super(ir_attachment, self).write(cr, uid, ids, vals, context)
  File "/usr/local/bin/openerp6/server/bin/osv/", line 3395, in write
    result += self._columns[field].set(cr, self, id, field, vals[field], user, context=rel_context) or []
  File "/usr/local/bin/openerp6/server/bin/osv/", line 830, in set
    self._fnct_inv(obj, cr, user, id, name, value, self._fnct_inv_arg, context)
  File "/usr/local/bin/openerp6/server/bin/addons/document/", line 101, in _data_set
    res = fnode.set_data(cr, base64.decodestring(value), fbro)
  File "/usr/lib/python2.6/", line 321, in decodestring
    return binascii.a2b_base64(s)

The cause is that the web client is sending back the value in the File Content textbox (in my case, the string "190.81 Kb"), instead of the newly submitted file data.

This issue was introduced in web client 6.0 revision 3369.

I attach a patch which resolves the issue
