I have a ZClass NetShowLogFile. It has baseclasses of CatalogAware and File. When I try to add a NetShowLogFile, my python script adds the file(between 200KB and 3MB), parses the file, executes many SQL methods(two per line in the file -- average 1000 lines), and context.REQUEST.RESPONSE.redirect()s to a different page. The problem is this: After it finishes parsing the file and inserting it's contents into the database, I get a Transaction error: Error Type: AttributeError Error Value: commit_sub <!-- Traceback (innermost last): File /home/zope/Zope-2.3.1b1-src/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /home/zope/Zope-2.3.1b1-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/zope/Zope-2.3.1b1-src/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: CatalogAware) File /home/zope/Zope-2.3.1b1-src/lib/python/ZPublisher/Publish.py, line 175, in publish File /home/zope/Zope-2.3.1b1-src/lib/python/Zope/__init__.py, line 235, in commit File /home/zope/Zope-2.3.1b1-src/lib/python/ZODB/Transaction.py, line 276, in commit AttributeError: (see above) --> Any ideas? It looks similar to http://classic.zope.org:8080/Collector/1895/view and to http://classic.zope.org:8080/Collector/629/view It also looks like I may have to move my files to LocalFS objects and rebuild my ZClasses :( Thanks for the second time today, Troy
