Programmatically setting UI Hints for runtime named where clause params

Question

Hi,
At runtime, I've added some named where clause parameters to my view object instance, set the where clause and then executed the query. Then, when navigating to the target page, where a af:query panel is shown and a af:table shows the filtered results, I see the bind variables I've just created appearing in the search area as mandatory fields.
My question is: how can I hide those runtime bind variables?
Thanks

I do want where clauses to be created at runtime instead of design time to improve DB performance
whereClause += "AND DEPARTMENT_ID = " + departmentId;Marge -
What you are doing is a recipe for POOR performance, not good performance. String concatenation in a where clause with no bind variables... ugh! Poor performance + poor security (you are now susceptible to SQL injection attacks).
I suggest that you do this at design time (where possible) and have a read of the documentation about view criteria.
And please, no matter what approach you use, PLEASE PLEASE PLEASE start using bind variables and not just jamming strings together to make your where clause, otherwise you are heading straight for disaster. I cannot stress this enough.
