When you migrate an application to VA Smalltalk that has been around since either VisualAge Smalltalk V1.0 or V2.0, you may get a packager warning saying there are 'No implementors of fixupNlsPool' when trying to package. If you are packaging as an IC, this will result in a runtime error when an attempt is made to run the packaged application.

To stop the error, browse implementers of initializeAfterLoad in your image. If there are implementers of this method, which is generated by VA Smalltalk, in any of your view classes you can delete them. This is obsolete code that was generated in previous VisualAge releases and is no longer needed. Deleting the implementers should clear up this particular packager warning and your application should run if packaged properly.
