Abstract:                  ISSUES WITH BAL RULE ENGINE - UPDATING ARRAYS VALUE

Description/symptom of problem:

Having a set of rules that modify the state of a complex 
variable. This complex variable happens to have two array 
variables as instance variable. Even though these rules do not 
change, update, or even reference any of these array variables, 
the BAL rules are changing the values of these arrays if the 
arrays are null just before invoking the rules. 
If the arrays are null before invoking the rules, then the 
arrays must be null after the rules are excuted. 
Unfortunately, for some very odd reason, executing the BAL 
rules, modifies the value of these arrays: it creates the 
array and then adds a NULL element to it. 

Directions to apply fix:


1) Shutdown WebSphere. It is important that you perform a controlled and complete shutdown of the server to ensure
   that all transactions have completed, before installing the fix.

2) Extract the .zip file to a directory. For example, extract to C:\temp.

3) Add the fix pack repository location in IBM Installation Manager:
   a. Start IBM Installation Manager.
   b. In Installation Manager, click File > Preferences > Repositories.
   c. Click Add Repository.
   d. Browse to or enter the file path to the repository.config file. The repository.config file is located in the directory where
      you extracted the compressed files. For example, enter C:\temp\repository.config, and then click OK.

4) On the main page of the Installation Manager, click Update.

5) Restart WebSphere


Directions to remove fix:
NOTE:  FIXES MUST BE REMOVED IN THE ORDER THEY WERE APPLIED.  DO NOT REMOVE A FIX UNLESS
       ALL FIXES APPLIED AFTER IT HAVE FIRST BEEN REMOVED.  YOU MAY REAPPLY ANY REMOVED FIX.

Example:  If your system has fix1, fix2, and fix3 applied in that order and fix2 is to be
          removed, fix3 must be removed first, then fix2 may be removed

1) Shutdown WebSphere. It is important that you perform a controlled and complete shutdown of the server to ensure
