Re: Problems with requestAttributeSelector

[Antonio Gallardo <ag...@agssa.net>]

Hi Salvatore,

I've not used xsp for long time now, Hoeweve, IIRC, the selector is 
triggered *before* the pipeline is set, hence when the selector checks 
for the request attribute it does not exist yet. A solution is to write 
a sitemap action.

Best Regards,

Antonio Gallardo.
