oh sorry. the code snippet is wrong. I was using @Persist("session") and it
didn't reflect in the StateObjectManager.
But once i switched to @InjectState , everything worked as expected. I think
the difference is that
@Persist pushes the object to session. But that object is not being managed
by hivemind unlike the ones you explicitly declare in hivemodule.xml -
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="user" scope="session">
<create-instance class="com.xyz.web.common.User"/>
</state-object>
</contribution>
Hence the StateObjectManager is probably not aware of the objects pushed
into session through @Persist("session")
That is my understanding..but i may be wrong :)
Btw, thank you all for guiding me through tapestry workers
