PersistenceItemException using property schema

I am using a property schema (with MessageContextProperyBase as property schema base)and inside ochestration, after setting some values to the context properties of property schema message needs to be saved into message box database.. which will be picked up by another orchesration having filters in receive port for the context properties..But I am geting following error.

Exception type: PersistenceItemException

Additional error information:

Failed to publish (send) a message in the batch. This is usually because there is no one expecting to receive this message. The error was The published message could not be routed because no subscribers were found. with status -1061151998.

Orchestration subscribed to this message is in running state. When i checked context properties of suspnded messages, none of my custom properties are promoted.. Is this error because of that..? Do i need to write code to promote these properties..? I was expecting biztalk to promote these properties since I am using a property schema.. Thanks in advance for all your valuable inputs

In order to have the context properties promoted from an Orchestration - you need to define a CorrelationType and have the Send shape initialize an instance of that CorrelationType (called a CorrelationSet)
