why: org.hibernate.LazyInitializationException: on rollback?

[allforjava.allforjava.aol.in]

Dear Team,

On using Transaction.instance().rollback(); OR @ApplicationException(rollback=true) the rollback is working.

However, when I navigate to another view it throws:
org.hibernate.LazyInitializationException: could not initialize proxy - no Session

And, when tried to invoke persist() (click on ViewEdit.xhtml 'Save' button) under same cid, it throws:

'detached entity passed to persist' hibernate exception.

Kindly assist as what else m'I missing?

I'm begining and ending conversations as:

<begin-conversation join="true"/>

...
   <navigation from-action="#{workLogHome.persist}">
       <end-conversation/>
    </navigation>
Note: Using SMPC

Thank you in advance!
