Re: Congratulations for Apache Click and some questions from a novice

Hi André,

I can shed some light on second question.

The request parameter are bound after the constructor was called, so 
you cannot
use these fields within the constructor.

If you move your code into onInit it should work.

If you need it inside the constructor you could read the paramter from the
request using getContext().getRequest().getParameter("enderecoIP");


AFAIK there is nothing like a ProgressBar (yet).
You might want to take a look at the clickclick project [1], there is 
an example
called "Lazy Load Demo" [2] (also it looks like the example is currently
broken), you could use this to show a message, that you're doing your analyzis
and show the result whens it's finished.
I'm currenty trying to implement this myself, so maybe I can help you if you
want to give it a try.
