VisCCG error?

[sracioppa]

Using VisCCG, I just can edit a ccg file, nothing else.
Every other action (e.g. validate, visualize Lexicon, Words or Rules) causes an exception, e.g. validating:

Exception in Tkinter callback

Can you give me a hint? Thanks!

It looks like this may be the same issue reported in an earlier post (https://sourceforge.net/projects/openccg/forums/forum/255819/topic/3727899); can you see if this fixes the issue? If so, we should update the code in the github repo.

Hi,
The problem is in the lex.py package. You have to change the following
comparision.

if not isinstance(s,types.StringType):
raise ValueError, "Expected a string"

==>

if not isinstance(s,types.StringTypes):
raise ValueError, "Expected a string"

Note that types.StringType ==> types.StringType[b]s[/b]

Thank you a lot! :-)
