Can't dynamically bind Request var to ViewObjectLink SQL (for BIBean Graph)

Question

Can anybody pleaaaase help? I'm trying to get a graph done with JSP and a BI Bean. I have got the graph working just fine, based on an unfiltered query of the ViewObjectLink. However, have not been able to figure out how to dynamically add and alter the criteria of the underlying ViewObjectLink query.
My research has found numerous references to the setWhereClause() and setWhereClauseParam() functions. I've placed setWhereClause() and setWhereClauseParam() calls in the constructor of the ViewObjectLink. But I always get exceptions :
JBO-30003: The application pool (test_16.AppModuleLocal) failed to checkout an application module due to the following exception:
oracle.jbo.JboException: JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=
JBO-29000: Unexpected exception caught:
oracle.jbo.InvalidObjAccessException, msg=
JBO-25036: An invalid object operation was invoked on type View Object with name FaVGetDueDatePcCtab2ViewImpl_120
Any and all help appreciated.
Thanks in advance,
John.

Thanks Keith.
It's a question of how one sets and accesses the query datasource of the ViewObject which underlies and populates a BIBeans graph.
I don't see how one binds criteria value(s) to the parameter placeholder(s) in the ViewObject object.
For example, the Query property of my ViewObject is:
SELECT FaVGetDueDatePcCtab2.PC0,
FaVGetDueDatePcCtab2.PC1,
FaVGetDueDatePcCtab2.PC2
FROM FA$V$GET$DUE$DATE$PC$CTAB2 FaVGetDueDatePcCtab2
The Where Clause propery is:
WHERE FaVGetDueDatePcCtab2.PC2 IN (?, ?, ?)
What wizard or method or means is used to bind the '?' placeholders with actual values?
Or do you think this is more a question for the Forms/Reports forum?
