I'm looking for documentation on implementing functions that can be used in EL in jsf pages. Maybe I'm missing something, but the best info I can find is that the a FunctionMapper object is used to resolve functions that show up in EL. But how can I define my own FunctionMapper? how do I set it? Can the default FunctionMapper be configured through an config file? I can't seem to find any info on this. Any reference will be much appreciated.
