examples of ASYNCH with ref Attributes

hi,

can anyone direct me to any ref or examples where,

you have an ASYNCH message but reference to <<BO.attribute>> inside of the Instant Message?

we have tried '+BO.attribute+'
also
<<BO.attribute>> but neither seem to work?

i guess i should describe the usecase better,

we are creating an instant message as want to pass some attributes into a message to inform someone when a task was completed.

"12 Tasks have been completed" should be the message

so we pick the recipient in the process but cannot seem to solve how to get the object info also.

solved;

If you create a process which creates the Message,
and refer to BO's or Attributes please be sure to add that BO as a Process Input.
