Not sure if i am answering your question, but i see a couple things:
- your jquery selector should be "#fl_ouvDataCriacaoFim" -- you need the '#' to target an ID
- yout jquery tag is inside the inputText tag -- put it outside the inputText tag. i'm not sure if it is legal inside like that, but it is its own thing.. not part of the inputText
hope that helps.
Thanks for the tips was missing the # before the id put the script
/* <![CDATA[ */
var $jq = jQuery.noConflict();
/* ]]> */
td in the head and ran.
