Hi Kris,
maybe my understanding is wrong. To be clear:
what I've tried is to implement this class:
public class ErpTapestryFilter extends TapestryFilter {
protected void init(Registry registry) {
// .. do some initialization
}
}
and replaced the "TapestryFilter" with my "ErpTapestryFilter" in the web.xml.
The result should be that the following method from TapestryFiler should be
overriden:
/**
* Invoked from [EMAIL PROTECTED] #init(FilterConfig)} after the Registry
has been created, to allow any additional
* initialization to occur. This implementation does nothing, and my be
overriden in subclasses.
*
* @param registry from which services may be extracted
* @throws ServletException
*/
protected void init(Registry registry) throws ServletException
{
}
What's wrong with that? Does "...maybe overriden in subclasses" mean: "...in
tapestry-internal subclasses" ?
Thanks,
Udo.
