Uppps ... sorry.
Problem:
The exception, java.lang.IllegalStateException:
Transaction org.exolab.castor.jdo.engine.TransactionContextImpl@493102
does not hold the read lock: A/3/32 -/-!
is throwed.
Remember that the mapping was:
<class name="A" identity="id">
<map-to table="table_a" />
<cache-type type="none" />
<field name="id" type="long">
<sql name="id_a" type="bigint" />
</field>
</class>
<class name="view" identity="id">
<map-to table="table_a" />
<cache-type type="none" />
<field name="id" type="long">
<sql name="id_a" type="bigint" />
</field>
<field name="fieldA" type="long">
<sql name="field_a" type="bigint" />
</field>
</class>
Finally, I must comment that I create a 'view' class instance, and then
(at this point the exception is throwed) I create a 'A' class instance. Two
instances are created in different transactions.
Thanks,
Quique
