Hi,
That is on our list of known bugs currently. Unfortunately this is a bug in the tools BusinessObjects provides to us to build Logicity so we are kinda in a holding pattern until it gets fixed upstream. We are hoping to have a build for Crystal 2008 done later this month and will see if it might be fixed in that version.
Basically what it comes down to is we set the action on the report along with various other settings and hand it off to Crystal. Crystal is supposed to look and see if the parameters are filled in or not and prompt if they are not. It is not doing that in the current build of the API and it only prompts the user if they select the View option. A workaround would be to view the report and choose the action you want from the viewer window.
Stay tuned,
Brian
