serviceBuilder convert-null not working, empty string becomes null

Hello everyone,

I got a problem in service builder with saving objects with empty strings '' that becomes null when saved to postgres database v9.6.
According to DTD, convert-null is true by default, and I have not modified this in service.xml.
Using Liferay CE 7.1 GA3.
No problem with this in Liferay v6.2, which always saved as empty string ''.

This may become problematic if the column is used in a unique index. since null is not considered equal, and therefore opens up for duplicates.

I could not found any other threads about this problem.
What can possible be causing this?

Thanks,
Erik

So change convert null to false?

I tried setting it to both false and true, but it makes no difference.
I think maybe that this functionality is done by Hibernate, but don't know how this parameter/flag is sent from serviceBuilder code to Hibernate?

Thanks,
Erik
