I have a one-to-one mapping based on a foreign key
Code:
CONTENT {
ID NUMBER(16),
XML_CONTENT BLOB
}
ARTICLE {
ID NUMBER(16)
NAME VARCHAR2,
ID_CONTENT,
FOREIGN KEY(ID_CONTENT) REFERENCES CONTENT
}
My mappings are:
In Content:
Code:
<one-to-one name="article" class="de.ems.cms.beans.Article"
property-ref="content" constrained="true"/>
In Article:
Code:
<many-to-one name="content" class="de.ems.cms.beans.Content"
column="ID_CONTENT" unique="true" cascade="all"/>
I create an Article (a) and a Content(c), I use
Code:
a.setContent(c);
and when I try to save I get the following error.
Shouldn't the Content be save automatically because of cascade="all"?
