Question: Successive use of a taglib by the container (i.e.: tagpool), what function reset the tag between usage????

[David Gagnon]

Hi all,

 I'm upgrading my old struts right now and several years ago I ran into 
the problem that since Tomcat has a TagPool and reuse tags, the state of 
the tag wasn't reseted beetween usage.  I looked into the new version of 
struts and I cannot find how the tag is resetted between usage. 

I looked into tomcat in the TagHandlerPool.reuse() and the release() 
function is not called at the end of each utilization but only when the 
tag is not used anymore (to be garbage collected).  So how Struts reset 
is tag between utilisation to avoid using the properties setted in the 
previous utilisation.

Thanks for your help on this!
Best Regards

   public void reuse(Tag handler) {
       synchronized( this ) {
           if (current < (handlers.length - 1)) {
               handlers[++current] = handler;
               return;
           }
       }
       // There is no need for other threads to wait for us to release
       handler.release();
   }
