Thanks for your response Clark.
Actually, I have a list of customers which I have to filter based on their
sales... but for that I have to build a qualifier to filter the data.
So, I will get customer Object reference from sales's objects, and finally I
have to extract all the customers having sales...
occasionally I have to build qualifiers for the non-class properties :)
Thank You,
Shravan Kumar. M
------------------------------
Am I correct in assuming that sales.toCust() is a related EO? If so, you should
be passing the name of the relationship as the key for the qualifier instead of
the name of the foreign key, for example:
EOKeyValueQualifier custQual = new EOKeyValueQualifier("cust",
EOQualifier.QualifierOperatorNotEqual, sales.toCust());
