Re: [webbeans-dev] contextual action methods

On one of my first reads of the Web Beans spec, I had this vision of being able to bind a method with arguments to a UI interface component and then have Web Beans inject the parameters at invocation time. This would give dependency injection that is isolated to the method call (and contextual). <h:commandButton action="#{hotelSearch.find}" value="Search"/> public void find(@Current SearchCriteria searchCriteria) {    ... } However, once again we get stumped by the EL. The EL is going to look for a method with no arguments or, as of EL 1.2, an argument count matching the parameterized EL expression. What I would like is for the EL to locate a method with the same name with 0 or more arguments where every argument can be satisfied by Web Beans. Naturally, overloading would not be allowed since it would introduce ambiguity. So you could have exactly one method like this to be used as an alternative to a no-args method (the restriction would be per method name of course). The downside of doing #{hotelSearch.find(searchCriteria)} is that you have to name (i.e., @Named) all possible arguments and you can't leverage binding annotations (everything is name based). We could do something like this in Seam 3, taking over the torch from Seam 2 that made Faces event arguments optional.
