title: How to open directory dialog in the client, in OpenERP7?
body: <p>I have to generate files containing some data I retrieve from database. User must have the option to select where to save the generated files, but how to show the directory dialog in the client? I used Tkinter, but dialog apperared in the server (not in the client). Then I changed to python-wx library, and the result was the same.</p>
  
  <p>I know OpenERP has a binary field, and you can select  a file from the client view, but I need to select a directory, not a file.</p>
  
  <p>Please, how can I resolve this problem?</p>
  
  <p>Cheers.</p>
