@andymc12 Thanks a lot for addressing this very edgy case. I was looking how
the current implementation works and basically I was trying to understand if we
could defer the evaluation of the HTTP parameters (like `@FormParam`) to a
later phase. In general, I think it would be feasible but would significantly
impact the existing design.
However, I think I found a simple trick to make it work: reordering parameters
initialization. Here is an interesting exercise:
- `Response processForm(@FormParam("value") String value, Form form)` -> does
not work
- `Response processForm(Form form, @FormParam("value") String value)` -> works
just fine
So the idea in the nutshell is to a modify `JAXRSUtils::processParameters` to
initialize parameters in a different order. In this case, the `Form` should be
initialized before any `@FormParam`, it triggers the reader interceptors and
the right values are propagated in `Form` and `@FromParam` arguments. It should
also work in case of constructors or class members.
What do you think?
Thanks!
