java - Having a null foreign key in torque 4 -

-

is there way torque translate value of 0 null, foreign key?

i have following schema:

<table name="juser" idmethod="native">  <column name="id" primarykey="true" required="true" type="integer"/>  <column name="name" required="true" size="2147483647" type="varchar"/> </table>  <table name="juserdepend" idmethod="native">  <column name="id" primarykey="true" required="true" type="integer"/>  <column name="juserref" required="false" type="integer"/>  <foreign-key foreigntable="juser">   <reference foreign="id" local="juserref"/>  </foreign-key> </table>

and table created sql: 

create table juserdepend(id serial not null primary key,  juserref int,  name text not null,  foreign key(juserref) references juser(id) on delete cascade );

as can seen, in juserdepend there optional foreign key(juserref) juser table, can't seem torque understand that. right have no way save juserdepend object null value in juserref, because torque uses integer value 0 database complain because it's not valid foreign key.

my preferred solution torque simple translated 0 null, foreign keys null allowed value. possible?

newer mind, found answer. added javatype="object" foreign key, , can set null.
