Sorry if I didn't do enough research and make my first question clear the first
It was MiscUtils/DataTable.py that was trying to load xxx.mkmodel/Classes.csv
that gave me the problem. DataTable.py at line 293 does an open for the
relative filename 'xxx.mkmodel/Classes.csv'. My script did not modify the CWD
and it was pointing to /python/webware at the point of failure.
(When I did modify the CWD to fix the above problem, something else broke - I
won't do that again.)
So I think my answer is the directory xxx.mkmodel/ must be placed in or copied
to the directory
/python/webware and the CWD must not be changed by any script (before
connecting to the MySQL database by calling MySQLObjectStore and
.readModelFileNamed). If that were documented in Quick Start, I would be
happy. Else DataTable.py must figure out the absolute address of the
Classes.csv file used by the generate process.
Your answer confused me. I downloaded and installed Webware/WebKit as a
(stable, yes I realize it is beta) Python application so I have the structure
/Python/Webware/WebKit. My code is not on the Python directory branch.
I think your answer said you are developing WebKit along with another
application, and have WebKit installed off the Python directory branch in an
application directory. Your different directory structure may be yielding
