Error description

• When trying to retrieve the contents of a HATS global variable
  using the getGlobalVariable function, with the
  bidiImplicit parameter, you can receive an
  java.lang.IndexOutOfBoundsException if the global variable does
  not exist.
  This problem happens when the code attempts to retrieve the
  contents of the GV at a specific index.
  
  For example:
  <%= ((TransformInfo)request.getAttribute(CommonConstants.
  REQ_TRANSFORMINFO)).getGlobalVariable("testGV", true,true).
  getString(0) %>
  

Local fix

• The workaround is to make sure the global variable has been
  created before trying to retrieve a specific index of the global
  variable.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Developers using the getGlobalVariable       *
  *                 method with the bidiImplicit parameter.      *
  ****************************************************************
  * PROBLEM DESCRIPTION: Using the getGlobalVariable method      *
  *                      with the bidiImplicit parameter fails   *
  *                      with a                                  *
  *                      java.lang.IndexOutOfBoundsException     *
  *                      if the global variable was not          *
  *                      created prior to retrieving it.         *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When using the getGlobalVariable(String name, boolean
  createIfNotExist, boolean bidiImplicit) method, if the GV did
  not exist prior to this call the GV was created with an
  initial value of null.  When the variable was accessed by
  index it would cause a java.lang.IndexOutOfBoundsException.
  

Problem conclusion

• The getGlobalVariable(String name, boolean createIfNotExist,
  boolean bidiImplicit) method in BaseInfo was changed to set
  the initial value of the newly created GV to an empty string,
  "", instead of null.
  

Temporary fix
