Hi there,
lately, my application started to crash on “Referenced column -
p_objectCountAttribute - not found”. It happens in a rather legacy environment,
Wonder 5.0 (as determined by finding CFBundleShortVersionString of Info.plist
in ERExtensions) / Java 1.6.0_65 / Mac OS X 10.6.8.
There's no such column nor my code tries to access it anywhere. I understand
Wonder adds this attribute programmatically to get the count of items; and
indeed, my code which triggers the exception looks like this:
===
int numberOfMasterRowsWithoutOwner() {
EOQualifier
mymasterrow=EOQualifier.qualifierWithQualifierFormat("importObject.dataBlock =
%@ AND recordOwner = NULL",new NSArray(this))
return ERXEOControlUtilities.objectCountWithQualifier(this.editingContext(),
'DBRecord', mymasterrow)
}
===
It used to work properly for quite a long time. Lately though it began to cause
exceptions like this:
===
Exception in thread "MainPageMasterRowsCountThread_M?sto Ústí nad Labem"
Semantic error 226. Referenced column - p_objectCountAttribute - not found.

Any idea what might be the culprit and how to fix the problem?
Thanks a lot,
