Simple cascade update not working

[Cobo]

Hello all,

I've done this tons of times, so I don't understand what's happening... The title says it all: when I update the ID of one record of the main table, the referenced records on related tables won't update even though they have a relationship between them with the option "Cascade update" clicked.

In the attached database, the main table "Expedientes" is related to table "Actuaciones".

Any idea why this may be happening? I'm truly desperated.

Thanks a lot in advance!

It seems to be working now... without doing anything, that's weird.

Although when I update the ID the form doesn't autoload the related registers, so I have to exit the form and enter again to see them there.

Is there any solution to this?

Thanks a lot!
