Unidac uniQuery component does not return keygenerator value

I'm having trouble inserting into Firebird using Devart's uniQuery component (Delphi 7 with Unidac). The field that is the primary key is in the fieds of the query and the configuration of the component is like this:

CAMPO_ID : 
ProviderFlags > pfKey > True
Required > False

Query:
Options > RequiredFields > False
UniQuery Editor > Options > Provider Interbase > GeneratorMode > gmInsert
UniQuery Editor > Options > Provider Interbase > KeyGenerator > Meu_sequence 

Even with this setting, an error occurs while trying to record.

  

Error: Violates foreign key constraint

With uniTable sure, but I need it to be with a uniQuery.
