Missing entity : display an error instead of masking it.

[jeremypsl]

Hello,

I am wondering if it is possible to display a missing entity instead of masking it ?
I mean if i put 3 entities in a line and one of them is not available anymore, it is just hided..
I would like to have an error icon or something.
Don't know if it is technically possible.

Thanks !

Define “not available”. An entity can be “unavailable” or not existing. If 1st case you will see the “unavailable” state, otherwise the entity will be not shown. You can use a “default” option to set a replacement label, but not a special icon.
