We get the error message when we retract the object.The piece of code is given below
if( c instanceof TransactionBulkBean ) {
retract(c);
}
if( t instanceof TransactionBulkBean ) {
retract(t);
}
// Retract Old Events
for( TransactionEvent ev : MATCHER.retractUnMatchedEvents(c, t) ) {
ev.setMessage(null) ; retract (ev);
}
We dont have support contract at this point of time,But we dont mind going in one by
future.We would like to get your help to get this issue addressed ASAP.
We would like to call and speak to you on urgent basis.Give us a call on 203 719 4625 or
give us the no we can reach you at.
Thanks
Prakash
