LastErrorMessage Shell Properties

LastErrorMessage shell property accessors provide a central, single text value to help identify "what went wrong" in certain functions. This is a mechanism to get an error message back to the script for complex actions like running transitions or REST calls.

Shell.SetLastErrorMessage("Some error message");

var errMsg = Shell.GetLastErrorMessage();
if ( !myRec.StartTransition( 7 ) ) { 
  Ext.WriteStream( "Error occurred starting transition: " &&& 
  Shell.GetLastErrorMessage() ); 
}

Shell.ClearLastErrorMessage();
