Business Components: Use ? style parameters

Question

Hi,
I am trying to use a ViewObject that needs to have a parameter passed to it for its selection criteria. I created the view object and checked Expert Mode to create my own query. Now here is the problem... inside my where clause I set up one condition as follow
where VgrApp.APP_ID = VgrUserApp.APP_ID
AND VgrUserApp.USR_ID = ?
It says the query is valid, but when I try to test the ViewObject from the Module, it says varibles not bound...likewise when I try to access the ViewObject from a JSP usebean. If anyone has any information on this matter I would appreciate it.
Thanks in advance,
Joe

There is no direct way to bind the Form Fields to the query.
You need to do the following:
Use the pageContext.getParameter("param_name") to get the value for the form field.
Use the am.invokeMethod to bind the variable as below in your view method:
setWhereClauseParams(null); // Always reset
setWhereClause(null);
setWhereClauseParam(0,qotHdrId);
executeQuery();
This should work. Hope this helps.
