Re: string-binding problem

could somebody confirm that the issue described below is a bug? Should I 
enter it into the bug tracker?

As it turns out, the only way to get around this is to change the 
application design to be like the workbench demo, where after changing 
the locale the user is directed to another page. If instead you want to 
redisplay the same page, it will not show the new localization.

regards
