JTable and Postgres cross-reference problem

[rafacarvalhido]

Hello, I´ve created a JForm (GUI) and added a JTable to it. Then right clicked the table and 'bind' -> 'elements'. So I imported the table I want from my database and the communication worked because the column names are now displayed on the table header.

But when I run the program, it gives the following error:

Internal Exception: org.postgresql.util.PSQLException: ERROR: cross-database references are not implemented: "cambio.publico.teste"

I believe the problem is because the jtable can be edited and said editions are automaticaly recorded on the database table which it is not allowing.

Is there a way to explicitly tell my postgres table to allow cross-reference?

Also I may be way off and the root cause be something else entirely. Thanks for the help.
