Hi David,
Hibernate walks through the associations therefore the call-stack is pretty long. I am surprised
that it works fine eventhough you get this exception.

Hi Martin,
I'm working with David, trying to do the Hibernate searches for the code
his model generates and the problem above is not just encountered on
generation. We can't actually store objects any more.
The stack trace on a JUnit test setup() looks like this:

I think David is going to send you the xsd directly as it is far too larg
to paste here!

Hi,
I finally narrowed this issue down. It is the addition of the
<xsd:element minOccurs="0" maxOccurs="1"
ref="gensec:instrumentDomain" ecore:opposite="issueData">
<xsd:annotation>
<xsd:appinfo source="teneo.jpa">
@PrimaryKeyJoinColumn
</xsd:appinfo>
</xsd:annotation>
</xsd:element>
That appears to cause the exception. I checked out the version of my xsd
that was prior to adding these new annotations to control which end of a
0..1 relationship the FK was placed. Just the addition of a single one
of these annotations causes the StackOverflowException.
Thx.

Hi,
I had a close look at the generated hibernate.hbm.xml and it is
generated with identical treatments for debtIssueData and issueData.
Which suggests that the in memory model that Teneo generates and uses is
different to that that would be generated by the hibernate.hbm.xml.
Unfortunately when I tried to get it to use that hibernate.hbm.xml using
both the PersistanceOptions.MAPPING_FILE_PATH with either relative or
full pathnames it got a HbStoreException and could not find the file. I
also tried the USE_MAPPING_FILE = true and it ran at least but produced
no schema.
I am on Windows XP using 1.0.1 Teneo.

Hi,
I cannot find a way forward with this problem.
In the end I decided to try to force the FK in the entities related 0..1
to instrumentDomain by adding these
<xsd:element ecore:opposite="instrumentDomain" minOccurs="0"
maxOccurs="2" ref="gensec:lastCAE" />
<xsd:element ecore:opposite="instrumentDomain" minOccurs="0"
maxOccurs="2" ref="gensec:debtIssueData" />
<xsd:element ecore:opposite="instrumentDomain" minOccurs="0"
maxOccurs="2" ref="gensec:issueData" />
i.e. forcing the FK in a 0..2 relationship. The hibernate.hbm.xml
generated does not make sense. Here are the 3 0..2 I show above as
inside the
<class name="com.stpenable.gensec.impl.InstrumentDomainImpl"
entity-name="InstrumentDomain" abstract="false" lazy="false"
table="`instrumentdomain`">
<one-to-one name="lastCAE" entity-name="LastCAE"
foreign-key="instrumentdomain_lastcae" cascade="all" lazy="false"
property-ref="instrumentDomain"/>
the other 2 do not appear!!!!!!
They appear as
<one-to-one name="instrumentDomain" entity-name="InstrumentDomain"
foreign-key="issuedata_instrumentdomain" cascade="all" lazy="false"
constrained="true"/>
inside the
<class name="com.stpenable.gensec.impl.IssueDataImpl"
entity-name="IssueData" abstract="false" lazy="false" table="`issuedata`">
and as
<one-to-one name="instrumentDomain" entity-name="InstrumentDomain"
foreign-key="debtissuedata_instrumentdomain" cascade="all" lazy="false"
property-ref="debtIssueData"/>
inside the
<class name="com.stpenable.gensec.impl.DebtIssueDataImpl"
entity-name="DebtIssueData" abstract="false" lazy="false"
table="`debtissuedata`">
How can it treat the same annotation (0..2) completely differently?? Is
this a bug?

Hi David,
What do you see generated on the java side? I would expect that the maxOccurs="2" will generate a
list in java. This should then generate a one-to-many in hibernate.
Btw, would it be possible for me to send me your complete model (by email)? This would help me to
look in more detail at the issues you encounter.
