Hi all,
how can one specify something like the following, to fetch datasets where
the value is not set:
myWODisplayGroup.queryMatch ().takeValueForKeyPath ( null,
"myEntity.myAttribute" );
I have queryMin and queryMax in addition.
There is a problem with a fetch spec, that drives me to do this!
Any pointers?
Thanks
Wolfram
