Harriet, Yep a lot of people are using this widget in 2.4 as well as my live preview site that is in 2.4. If you are using the compiled version than per the instructions all you would have to do is copy the eSearch folder to the widgets folder in your flex viewer deployment and add this xml to your main config.xml:<widget label="Enhanced Search" left="60" top="400"
icon="assets/images/i_search.png"
config="widgets/eSearch/SearchWidget.xml"
url="widgets/eSearch/SearchWidget.swf"/>
A mistake that many people make is that Flex is a case sensitive language so you have to copy the folder exactly as in the instructions (i.e. eSearch).
