> Hi all,
> I'm running with struts 1.1 and I tried to migrate to 1.2.9 this morning.
> My biggest problem is that I needed to change the code base of my 1.1 to put
> new feature I needeed. One of them is that I introduced new scope like:
> window scope So I have
> ApplicationScope
> SessionScope
> WindowScope
> RequestScope
> PageScope.
> This allow me to have multiple browser windows on the same application and
> they not interfering. To do so I needed to patch the RequestUtil.lookup and
> now the TagUtils.lookup method. My problem is that there is no way in. The
> TagUtils defines an instance but it's a private final variable. So no way to
> plug in a new TagUtils classe in there?! For sure that would be a good
> feature for me :-)
> If the instance variable is at least protected and not final. It would be
> possible to create my new WindowScopeEnabledTagUtils class that inherit from
> tagUtils and change the instance for my new instance. That would have been
> great! Is that can be done ? Is there a reason why thing are like that?
> Have been away from the lastest version of struts and I have some catchup to
> do :-)
> Thanks for your help
> Best Regards
> /David
> public class TagUtils {
