Thank you SergeySmirnov,
My enviroment is:
Browser Firefox 22.214.171.124
- In Internet Explorer 7.0.6 and Opera 9.26 is perfect
so, does this mean that it is about http://livedemo.exadel.com/richfaces-demo/richfaces/dropDownMenu.jsf?c=dropDownMenu, but about the richfaces-demo jar deployed to the JBoss, right? Otherwise, there is no reason to speak about the server type.
Are you not able to get it to work when you point your browser to the RichFaces demo site (on exadel.com) as well as your local server?
I'm having no problems with rich:comboBox (RichFaces 3.2.0GA) on both JBoss and Sun Java Application Server, but I am using Firefox 3 beta 4.
Could this be a locale issue? What happens when you set your browser to the en-US locale and try to use the control?
