Description

We need an easy way to pass parameters from JavaScript to Java via a function that takes parameters. For example, of JQuery UI event callbacks, the function takes two parameters: event and ui. But, these aren't the parameters you want to pass to Java. A conversion is needed.

I was thinking about the following: let getCallbackFunction take a CallbackParameter vararg, with 4 implementations for CallbackParameter: ContextParameter, ExplicitParameter, ResolvedParameter and ConvertedParameter. A context parmater, only provides context to the function, it is not added to the Ajax call. Both event and ui are context parameter. Explicit parameters are context parameters that are also passed to the Ajax call. Resolved parameters are resolved using some javascript code. The last adds a context parameter and a conversion script to add it to the Ajax call.
