Biztalk 2006 R2 - fatal error X1001: unknown system exception

One of those weird errors that Biztalk SDK and Visual studio 2005 has thrown up.The error occurs when trying to create an orchestration with a receive port that has multiple operations in the orchestration.

Each receive shape property Activate is set as true. This lets the orchestration receive different message types in any given order using correlation.The error occurs when you have not set one of the receive shapes Initializing Correlation Sets.

Visual Studio should have shown an activation correlation is required error instead of unknown system exception.
