[ZW.pl 2]

Hello community! I've one problem... I have some system.. In my client all works, but in my friend's client syserr give us:

kolorDialog.LoadDialog - <type 'exceptions.KeyError'>:'window'

this fragment in gui looks:

 def LoadDialog(self):
  try:
   pyScrLoader = ui.PythonScriptLoader()
   pyScrLoader.LoadScriptFile(self, "ulepki.py")
  except Exception, msg:
   (type, msg, tb)=sys.exc_info()
   dbg.TraceError("kolorDialog.LoadDialog - %s:%s" % (type, msg))
   app.Abort()
   return 0

Some propositions?

Check your ulepky.py syntax.

Check if the files exits in root

Check if the file string exists in root.xml

If you are not using XML, try to switch to a pack witch use XML because non-xml packer can pack only specific files

syntax?
