propertyFilter doesn't work

Hi,
rookie question!?
I added propertyFilter, but when I hit ENTER, nothing happens.
The cursor just stays inside the propertyFilter textfield with no refresh of the data.
autoApply is true, dataLoader, etc. seem to be set ok…

Maybe any collision with the ENTER-shortcut? that omits the refresh?
Thanks in advance…

PS, JMIX 1.5
PS2, found, that simple entities work, but not those with joined tables…

PS3, seems to be solved: if there’s additional filter on same dataloader, there’s no refresh…
