Abstract:  Temporary variables of type String are incorrectly initialized to a value of 'null'.

Description/symptom of problem:  
JR31816 resolves the following problem:

ERROR DESCRIPTION:?                                             
Custom transformation inside BO Map. When using a variable it is
always initialized to "null" string value rather than null.     
                                                                
We have an interface map which in turn calls a BO map. Inside   
the BO map, we define a local variable of type string. Then we  
tried to print the value stored in the variable, and also the   
length of it.                                                   
                                                                
It turned out that the variable has value "null" and length 4   

LOCAL FIX:?                                                     
Programmatically set the String variable to null.               

PROBLEM SUMMARY:?

USERS AFFECTED:
Webpshere Process Server v6.1.2 BO Mapper
users who make use of the temporary
variables in their maps,

PROBLEM DESCRIPTION:
Temporary variables of type String
are incorrectly initialized to a
value of 'null'.

RECOMMENDATION:
None

The code in BO Mapper code generator incorrectly assigns the
value to the temporary variable of type String.

PROBLEM CONCLUSION:?                                            
Applying this interim fix will resolve the issue.
