name="text"
dataFieldName="text"
loadOnTextChange="true"
indicator="indicator"
dropdownHeight="300"
cssStyle="width: 200px;"
searchType="substring"
autoComplete="false"
showDownArrow="false"
loadMinimumCount="3"/>
<img id="indicator"
src="${pageContext.request.contextPath}/images/indicator.gif"
alt="Loading..." style="display:none"/>
[JSON][{"id":420,"questionType":{"declaringClass":"class

funny thing is that now I remember the code(duh!), it is in the struts

with the autocompleter and the json that your action is returning.
