Disable converters for request parameters in the URL
How can I disable auto convertion for request parameters that are of type Integer? I'm not sure but it looks like that Seam perform the conversion during the render response phase. In my component I have this:
@RequestParameter("pn")
@Out(value="pn", required=false)
private Integer pageNumber = -1;

If that is not possible then I will have to change it to String, parse to int and catch any number format exception.
