With an eCore that looks as follows:

  <eClassifiers xsi:type="ecore:EClass" name="Case1">
    <eAnnotations source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData">
      <details key="name" value="Case1"/>
      <details key="kind" value="elementOnly"/>
    </eAnnotations>
    <eAnnotations source="bds">
      <details key="isCase" value="true"/>
    </eAnnotations>
    <eAnnotations source="teneo.jpa">
      <details key="value" value="@Table(name=&quot;ROBTEST_CASE1&quot;)&#xA;@DiscriminatorValue(&quot;com.example.robtest.Case1&quot;)"/>
    </eAnnotations>
    <eStructuralFeatures xsi:type="ecore:EAttribute" name="stringLob" unique="false" upperBound="-1">
      <eAnnotations source="http:///org/eclipse/emf/ecore/util/ExtendedMetaData">
        <details key="kind" value="element"/>
        <details key="name" value="stringLob"/>
      </eAnnotations>
      <eAnnotations source="teneo.jpa">
        <details key="value" value="@Lob&#xA;@Column(name=&quot;STRINGLOB&quot;, length=&quot;1048576&quot;)"/>
      </eAnnotations>
      <eType xsi:type="ecore:EDataType" href="http://www.eclipse.org/emf/2003/XMLType#//String"/>
    </eStructuralFeatures>
    <eStructuralFeatures xsi:type="ecore:EAttribute" name="bdsId">
      <eAnnotations source="teneo.jpa">
        <details key="value" value="@GeneratedValue(strategy=&quot;AUTO&quot;)&#xA;@Id&#xA;@Column(name=&quot;BDS_ID&quot;)"/>
      </eAnnotations>
      <eAnnotations source="bds">
        <details key="isId" value="true"/>
      </eAnnotations>
      <eType xsi:type="ecore:EDataType" href="http://www.eclipse.org/emf/2002/Ecore#//ELongObject"/>
    </eStructuralFeatures>
    <eStructuralFeatures xsi:type="ecore:EAttribute" name="bdsVersion">
      <eAnnotations source="teneo.jpa">
        <details key="value" value="@Version&#xA;@Column(name=&quot;BDS_VERSION&quot;)"/>
      </eAnnotations>
      <eAnnotations source="bds">
        <details key="isVersion" value="true"/>
      </eAnnotations>
      <eType xsi:type="ecore:EDataType" href="http://www.eclipse.org/emf/2002/Ecore#//ELongObject"/>
    </eStructuralFeatures>
  </eClassifiers>


So the "stringLob" has the following annotation:

Quote:

@Lob
@Column(name="STRINGLOB", length="1048576")


If this is used to generate a hibernate mapping it gives:

<hibernate-mapping auto-import="false">
	<class entity-name="robtest.Case1" abstract="false" lazy="false" discriminator-value="com.example.robtest.Case1" table="`BDS_1_ROBTEST_CASE1`">
		<meta attribute="eclassName">Case1</meta>
		<meta attribute="epackage">http://example.com/robtest</meta>
		<id name="bdsId" type="java.lang.Long">
			<column not-null="false" unique="false" name="`BDS_ID`"/>
			<generator class="native"/>
		</id>
		<discriminator column="`DTYPE`" type="string"/>
		<version name="bdsVersion" type="java.lang.Long">
			<column not-null="false" unique="false" name="`BDS_VERSION`"/>
		</version>
		<property name="stringLob" lazy="false" insert="true" update="true" not-null="false" unique="false" type="text">
			<column not-null="false" unique="false" name="`STRINGLOB`" length="1048576"/>
		</property>
	</class>
</hibernate-mapping>


But because the upperBound="-1" is specified, I would have expected it to generate a list for stringLob:

<hibernate-mapping auto-import="false">
	<class entity-name="robtest.Case1" abstract="false" lazy="false" discriminator-value="com.example.robtest.Case1" table="`BDS_1_ROBTEST_CASE1`">
		<meta attribute="eclassName">Case1</meta>
		<meta attribute="epackage">http://example.com/robtest</meta>
		<id name="bdsId" type="java.lang.Long">
			<column not-null="false" unique="false" name="`BDS_ID`"/>
			<generator class="native"/>
		</id>
		<discriminator column="`DTYPE`" type="string"/>
		<version name="bdsVersion" type="java.lang.Long">
			<column not-null="false" unique="false" name="`BDS_VERSION`"/>
		</version>
		<list name="stringLob" table="`BDS_1_ROBTEST_CASE1STRINGLOB`" lazy="true" cascade="all,delete-orphan">
			<key update="true">
				<column name="`CASE1_STRINGLOB_BDSID`" not-null="true" unique="false"/>
			</key>
			<list-index column="`CASE1_STRINGLOB_IDX`"/>
			<element type="java.lang.String" not-null="false" unique="false" type="text">
				<column not-null="false" unique="false" name="`STRINGLOB`" length="1048576"/>
			</element>
		</list>
		<property name="stringLob" lazy="false" insert="true" update="true" not-null="false" unique="false" type="text">
			<column not-null="false" unique="false" name="`STRINGLOB`" length="1048576"/>
		</property>
	</class>
</hibernate-mapping>


Is anyone able to assist me with this, is it a know problem, or am I doing something wrong?

Thanks

Rob

Hi Rob,
This is an omission in Teneo, I am solving it and will do a new build sometime today.

Hi Rob,
I published a new build which should solve this.

Thanks Martin!

That was a super quick fix.

Please would you be able to point me at the fix that you made - I'd be very interested to see what you needed to change - we are using an older version, and I'd like to see it I can find a way of incorperating your change.

Thanks

Rob

Hi Rob,
It is this changeset:
http://git.eclipse.org/c/teneo/org.eclipse.emf.teneo.git/commit/?id=c2589b7076d2e1cabd099fd2883bdb5416d22f01

But more specifically this change:

Hi Martin,

Thanks for the information. I have managed to port the change in EFeatureAnnotator into some test code, and it now does indeed generate the expected mapping.

Sorry to ask a stupid question, but are all the "Audit" changes also required?

The reason I ask is that I'm having trouble in my test code persisting an EObject into the newley generated tables from the new hibernate mapping and didn't know if it was because I have only taken this one change.

Thanks

Rob

Hi Rob,
No the auditing changes are not related to this... Should have pushed that part in a separate commit.. The auditing
changes are for this new feature:
http://wiki.eclipse.org/Teneo/Hibernate/Auditing

Thanks for your help Martin.

I've now got it all working like a charm!
