Here is the autocompleter tag and the JSON returned...

<s:label name="text" value="Search for Question Text:" />
<s:url id="search" namespace="/search"
value="/search/searchByText.action"/> 
<s:autocompleter theme="ajax" href="%{search}" 
		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
gov.hhs.fda.datacall.model.QuestionType"},"text":"Is your Java
Application a ME, SE or EE
application?"},{"id":440,"questionType":{"declaringClass":"class
gov.hhs.fda.datacall.model.QuestionType"},"text":"If your Java
Application is an SE application does it use Java Web
Start?"},{"id":450,"questionType":{"declaringClass":"class
gov.hhs.fda.datacall.model.QuestionType"},"text":"If your Java
Application is a Java Web Application, list the application server used
for production"},{"id":490,"questionType":{"declaringClass":"class
gov.hhs.fda.datacall.model.QuestionType"},"text":"List any Java Web
Services Technologies
Used"},{"id":500,"questionType":{"declaringClass":"class
gov.hhs.fda.datacall.model.QuestionType"},"text":"List any Java Web

funny thing is that now I remember the code(duh!), it is in the struts
widget. It seems like the json is empty. Paste the section of your jsp
with the autocompleter and the json that your action is returning.
