Hello,

sorry … but I still having trouble with the usage of multiple groups in jqgrid. I hope you can help me.

Well, let me explain the situation.

I have to implement a simple booking system. In the backend of this system I use jqGrid to display all reservations, bookings and cancellations in a table. It is possible to cancel a reservation, but not a booking.

The backend user should be able to use 3 filter options stand-alone or in combination:

– Reservations – displays all records, where booking and cancellation is an empty string: (booking = “” AND cancellation = “”)

– Bookings – displays all records, where booking is set by timestamp: (booking != “”)

– Cancellations – displays all records, where cancellation is set by timestamp: (cancellation != “”)

Each of these 3 filter options – seperately performed – works in the expected manner.

But if I try to use the Reservations filter option in an (OR-)relation with the Bookings-filter option
