Hi.
The JSF expression language does not accept parameters for functions, you are right. The new specification for the JSP and JSF common expression language might have a possibility to do that, though.There are workarounds for this: implement the map interface. Provide as a key the parameter you want to provide to the function. use it something like the following: "#{mapname['functionParameter']}". In the getter of your map, call the function with the key as the parameter, that's it.
The map trick is well-known, but it's a VERY cumbersome workaround. I can't imagine a worse solution.
Bye. /lexi
