During usage of Fiji components you may get the js error that AC_FL_RunContent is not found. It is caused by RichFaces configuration of your application. Check if your web.xml contains the following code: <context-param> <param-name>org.richfaces.LoadScriptStrategy</param-name> <param-value>ALL</param-value> </context-param> Solutions: 1. Comment this param in web.xml (it can reduce perfomance) 2. Or add '<a4j:loadScript src="resource:///com/exadel/fiji/renderkit/html/AC_OETags.js"/>' on your page.
