Hi everyone,
I'm trying to make a widget for users to subscribe to a newsletter.
Here's the code:

<?php 
/**
 * Widget form the NETForms Newsletter 
 * the user only need to input his email adress
 */
class NewsletterWidget extends Widget {
	
	static $db = array(
		"TitleNLW" => "Text",
		"TextNLW" => "Text",
		"PlaceHolderTextNLW" => "Text",
		"SubmitButtonTextNLW" => "Text",
		"UserKeyNLW" => "Text",
		"MailingListKey" => "Text"
		);
		
	static $cmsTitle = "Widget NewsletterWidget";
	static $description = "Widget for a user to subscribe to the NETForms newsletter";
	
	function getCMSFields() {
		return new FieldSet(
			new TextField("TitleNLW", "Title on top of widget"),
			new TextField("TextNLW", "Text description under the title"),	
			new TextField("PlaceHolderTextNLW", "Text inside the submit field that will disapear when the user put something else"),
			new TextField("SubmitButtonTextNLW", "Text for the submit button"),
			new TextField("UserKeyNLW", "NETForms user key"),
			new TextField("MailingListKey", "NETForms mailing list key")
			);
	}
	
}

class NewsletterWidget_Controller extends Widget_Controller {
	
	public static $allowed_actions = array(
			"NewsletterForm"
		);
		
	function NewsletterForm() {		
		$header = '';
		$textButton = '';
		
		$fields = new FieldSet(
			new HeaderField($header, $header, 4),
			new EmailField('Email')
			);		
		$actions = new FieldSet(
			new FormAction('SendNewsletterForm', $textButton)
			);		
		$validator = new RequiredFields('Email');
		
		return new Form($this, 'NewsletterForm', $fields, $actions, $validator);
	}
	
	function SendNewsletterForm($data, $form) {
		
		$userKeyTest = 'a1434f';
		$mailListKeyTest = '98550b77-4e';

		// get email from user entry
		// $email = $data['Email'];
		
		$url = 'https://api.netscoop.ca/service.asmx/saveContact?userkey='.$userKeyTest.'&greeting=&firstname=&lastname=&email='.$email.'&externalkey=&mailinglistkey='.$mailListKeyTest;

		// create a new cURL resource
		$curl = curl_init();

		// set URL and other appropriate options
		curl_setopt($curl, CURLOPT_URL, $url);
		curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($curl, CURLOPT_HEADER, false);
		curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
		curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 1);
		curl_setopt($curl, CURLOPT_CAINFO, getcwd() . "/somesite/somecertificate.crt");
		// grab URL and pass it to the browser
		curl_exec($curl);
		curl_close($curl);
		
		// go back to home page
		Director::redirectBack();
	}
	
}

When I try to submit an email, I get this (in dev mode)

[User Error] No widget found
POST /widget/58/NewsletterForm

Line 247 in C:\web\sitename\sapphire\core\control\ContentController.php

239 		// find widget

243 			$widget = $this->dataRecord->$widgetAreaRelation()->Widgets(
244 				sprintf('"Widget"."ID" = %d', $SQL_id)
245 			)->First();
246 		}
247 		if(!$widget) user_error('No widget found', E_USER_ERROR);

249 		// find controller
250 		$controllerClass = '';
251 		foreach(array_reverse(ClassInfo::ancestry($widget->class)) as $widgetClass) {
252 			$controllerClass = "{$widgetClass}_Controller";
253 			if(class_exists($controllerClass)) break;

I've seen a lot of people struggling with form inside a widget ... anyone have any idea?

for whom ever struggle with that kind of problem, simply add at the end of your Widget_Controller

function Link() {
	    return $this->class;
    }

and it'll do the tricks.
