1. go to Picking Tray Clearing (Prototype)
   => see filter: scan picking slot OK
2. use Scan picking slot filter
   => it looks like a barcode filter, you write smth like 105.0 and press enter. Filter works fine
3. press on filter again
   => the value is still there. If you want to remove it delete and press enter OK
4. remove what you wrote, press enter
   => all slots are shown OK
5. use the filter again on a picking slot that doesn't exist
   => Error: Zum Geschäftspartner <-1>, Standort...
   Server error
   Zum Geschäftspartner <-1>, Standort <-1> konnte kein Picking Slot gefunden werden.
   and the last slot you had filtered is still there OK?
