The "Tapestry5OutputLocaleNumber" page has been changed by MarcusVeloso. The comment on this change is: google code project myt5lib is updated.. http://wiki.apache.org/tapestry/Tapestry5OutputLocaleNumber?action=diff&rev1=4&rev2=5 -------------------------------------------------- - A component to display formatted numbers and dates according to locale, using literals (integer, decimal, currency, date e date(MM/yyyy)). It's based on Tapestry Output component. + This content was moved to the myt5lib project.
