WebServiceForm makes ProxyRediector crush when passing an url containing unecoded specials characters.

If you define a WebServiceForm lniked to a Model with getMethod line 61 of WebServiceForm.js is executed

WebserviceForm.js line 57
if (httpPayload.method.toLowerCase() == "get") {
httpPayload.url = this.webServiceForm.action + "?";
for (var i=0; i<this.webServiceForm.elements.length; ++i)

'element.value' is the parameter value element value from a web form, but what happen when this value contains (i.e. whiteSpace tabs ),?If those are not escaped would generate an erronous HTTP URL (http:\\locahost:8080\myApp\param1=Hello World) and ProxyRedirector Crush getting 505 error from webServer.

So to fix this bug I have modified line 61 with this.

line 61 --> httpPayload.url += element.name + "=" + escape(element.value) + "&";

Done that the ServerURL param passing to ProxyRedirector is http:\\locahost:8080\myApp\param1=Hello%20World

Notice that the error is independent from the browser because the error is raised to ProxyRedirector before the OutputStream of the browser is being writed.So I believe this patch would work properly in all browser .
