I'm doing something simple:
return catalog.searchResults(sort_on='dateofpublication')
...and getting something horrible:
Error Type: TypeError Error Value: unsubscriptable object
Further scoping out this problem has expanded it: - this bug isn't limited to 2.4.0bx, it's also manifests at least in 2.3.2 and probably in 2.3.1+. ...and narrowed it: - the bug occurs when you sort on an index where more than one indexed item has the same value. For example, if: x=SimpleItem() y=SimpleItem() z=Simpleitem() x.fred=1 y.fred=1 z.fred=2 ...now if you have a FieldIndex called 'fred' and catalog this lot, you'll get the error when you do a search along the lines of: r = Catalog(sort_on='fred') However, if you changed it so y.fred=2 and z.fred=3, you wouldn't get any unexpected behaviour :-S It appears that IITreeSet objects don't like being subscripted. That sounds kindof weird, but then it doesn't look like IITreeSets should be appearing in that context anyhow... Help! Chris
