Hi Michael,
When you publish a report initially you have to link inputs controls and set how you want them to display. In Jasper Report Server right mouse click on the report and select edit, then select Controls and Resources, then scroll to the bottom of the page until you see
then Change Pop Up Window to In Page
Regarding the input controls itself you need to link them in Jasper Server after publishing.
In the same area as the Input Control options you will see a link that says add input control.
For your 2 keys follow the path that is highlighted in yellow above. Note you will need to remove the existing Input Control and New for each parameter you have.
I think this is documented somewhere (probably much more clearly then my documentation skills) but I am not able to find it at the moment.
Hopefully I have led you in the right direction.
Regards,
Steve
