Hmm, sounds like that might be a bit of a bug on the FME side

@philippeb not quite sure understanding this.   Domains are an independent object in the GDBs so can have as many as wish, well up to whatever the limit is of the maximum count of Domains that are allowed to be created in a GDB anyway!

Are you instead saying that the “Coded Domain” editing window in FME2024 has become Modeless?  Ie. You can continue opening more and more Coded Domain windows for the same Attribute without first closing the first Coded Domain window?

Well….in theory, FME “could” support multiple Domain creation, although the Writer does need to choose only 0 or 1 of those Domains to associate with the field.

The Writer in FME2021 was certainly a little clunky in this respect.  It did not allow the user to easily create extra Domains, and any Domains created must be associated with a Field in order to be created.  Those are actually not limitations of the GDB needing to be followed since can create or destroy Domains independently of the GDB fields, so the FME2021 Writer in this respect is artificially constrained.

In don’t know then if in FME2024 if there was attempt to update the Writer to give more freedom for creating extra domains, although the GUI would in this case have to give the option for the user to pick which of those Domains, if any, to associate to the Feature Class / Table field.
 

@bwn I interpreted this as you could create a domain in a domain

@hkingsbury ….can see that now! Missed that when looked over original screenshots

Yeah, that will be a UI bug.
