Write the UIComponent Class

Hint:
Why write custom components
Icefaces doesn’t always play nice with other component libraries. ie. ajax4jf, it does work with the apache tomahawk but some components have limited functionality. The icefaces developers quide has a chart of compatibility. The icefaces developers guide has a wealth of information and should be one of the first places to look for info.
