This is odd. This certainly works for me. Here is an example from one of my
map.xml files (created by the Modeler) :
This part is a listener within <obj-enntity> tags:
<entity-listener class="com.foo.listener.MyListener">
<post-persist method-name="objectPostPersistCallback"/>
</entity-listener>
This part is callbacks on persistent objects themselves:
<post-add method-name="onPostAdd"/>
<pre-update method-name="onPreUpdate"/>
These are per-entity callbacks/listeners. Are you setting a listener per
DataMap? (I personally haven't used "global" listeners, but those should work
too). Could you confirm - we'll re-test this case then.

Personally I am moving to setting everything programmatically, as it allows me
to have different listeners for the same shared entities in different Java
projects. So my preferred method is the latest 3.1M2 API based on annotations:
runtime.getChannel().getEntityResolver().getCallbackRegistry().addListener(listener)
But again - this is for per-entity listeners. Not per-DataMap. (Which reminds
me - we need to support this flavor in per-DataMap case).
