When using the "callback" action, optparse requires that you STILL specify a "dest" parameter, though it is not required or used by the option parser. In fact, if you do not include the "dest" parameter, your options will still work properly, but optparse will generate an exception when calling the "--help" option. Not specifying a "dest" parameter will result in the following Exception when using the default "--help" or "- h" option: File "c:\Python23\lib\optparse.py", line 229, in format_option_strings metavar = option.metavar or option.dest.upper() AttributeError: 'NoneType' object has no attribute 'upper' by simply adding a bogus bug, the --help / -h option works properly even though the dest isn't actually used.

Logged In: YES user_id=14422 I'm pretty sure I fixed this in Optik 1.5 / Python 2.4. Can you 1) verify if the bug is still there in Python 2.4 and 2) if so, supply a small script demonstrating the problem?

Logged In: YES user_id=14422 ahmado -- please check if this bug is still present in Python 2.4 / Optik 1.5. If you do not respond in a week or two, I will assume that the bug is fixed and close this report.

Logged In: YES user_id=14422 No response from original poster after almost a year, so I'm assuming that I did indeed fix this bug in Optik 1.5 / Python 2.4.
