Disabling AutoOff Collection Tracking
</title>
<para>
The default behavior of openJPA in tracking collections is that if the number of
modifications to the collection exceeds the current number of elements in
collection then openJPA will disable tracking the collections.
Added a Compatibility property to disable turning off the collection tracking.
</para>
<para>
The behavior of Auto disabling of collection tracking can be avoided by setting
the value of the <literal>openjpa.Compatibility</literal>
property <literal>autoOff</literal> to <literal>false</literal>.
The default behavior of auto disabling the collection tracking
is not changed. But when the above property is set then the collection tracking
will not be disabled automatically.
