   Priority:  medium        |   Milestone:  Maestro-4.0
  Component:  Maestro       |     Version:

----------------------------+-----------------------------------------------
 A change in the Maestro API sometime in the last few weeks now results in
 an exception being thrown when creating a runtime map.

 I rolled back some Maestro API DLLs that I had built and my app runs again
 - hopefully there is enough in the stack trace to see what the issue is.

 It looks to be layer-dependent as on my test data in the office it does
 not occur, only on a complex site with many data connection types (SHP,
 SDF, ODBC) including joins and base layers.

 The build that caused the err below was from Friday 3 December.


 Exception Details: System.NullReferenceException: Object reference not set
 to an instance of an object.

 Source Error:


 Line 248:
 Line 249:               RuntimeMap rtMap = mpSvc.CreateMap(md);
