I expirienced the behaviour that the first item in the Application Path Member from a Application Path List will be deleted as far as the first item in the Application Path Member List will be selected in anather Application Path List without saving. This is according to severals peripherals as well.
Configuration Manager > Application Path List
In the Application Path List "McalMediaRouting" the following Application Path Members are configured.
For this example, the first Media Routing Domain for the Peripheral is Chat.
Now, adding a new Application Path Member for the Application Path List "SiebelMediaRouting" with a new Media Routing Domain, which is not yet assigned to a Application Path List.
Select the same Peripheral PG1A_CCM and choose the new MediaRouting from the list. At this point the Application Path Memeber with the Media Routing Domain "Chat" will be deleted in the Application Path List "McalMediaRouting". This will be deleted even without saving it.
UCCE Version 9.0.2 used.
Is this per design or is this a defect?
