a4j:jsFunction Help--Newbie

[gwzoller]

Hello,

I'm trying to find an example of a4j:jsFunction that passes AND returns a value between javascript and Seam/Java. I've found examples that do one or the other, but not both at the same time.

For example:

I have a Java api in a Seam component 'foo':

@Name("foo")
public class Foo {
 public String sayHi(String msg) {
 return "Hi, "+msg;
 }
}

What should the a4j:jsFunction code look like to call sayHi(), passing in a message and reading the returned value? I've tried several variations and haven't been able to get both passing and returning working.

Thanks for any help!
