I have an odd view that contains the code:

LEFT OUTER JOIN delimgr!master ;
        ON CustomerProducts.iid = master.fk_product ;
       AND Master.route == ?vp_route 

The problem I'm running into is when this view is opened (even with NODATA), I'm getting prompted for the view parameter. Where would I be able to put a dummy definition for the vp_route parameter that would remain in scope when the framework tries to open the view? PostInitHook() of the DE seems to be too late. Once the view is opened, it works just fine for me.
