How can I display only devices belonging the intersection of two device group when configuring a service?

[AlaeddineJebnoun90723]

Hello,

Is it possible to display the devices that belgons to two device-group in the same time. For exemple I have a device-group that contains [ dev-1 dev-2 dev-3  dev-4 dev-7] and another device-group that contains [ dev-1 dev-3 dev-4 dev-5 ]. When I configure my service I want to see only [ dev-1 dev-3 dev-4 ].

I tried to use tailf:non-strict-leafref extension but it always displays all the devices that belongs to the second device-group.

I would try a must expression and say that it must be in member of both lists. It will definitely do the validation but I am not certain it will give you tab-completion.

Thank you for your reply vleijon.

Could you please give an exemple of how I can use must statement to check if a device belongs to a device-group.
