Wrong SessionKey name in session

When using this component and try to validate the Captcha sessionkeyname against an input String (using the example approach), I found that the SessionKeyName value is null. But what is really happening is that the SessionKeyName varname is wrong. For example, insted of been "captchaSessionKeyName", when I list my session vars, it shows "captchaSessionKeyName_mySessionKeyName" (name appended twice or more).

A work around for this while get patched, in order to get the session key name could be:

public final static String SESSION_KEY_NAME = "mySessionKeyName";

HttpSession httpsession = (HttpSession) FacesContext.getCurrentInstance().getExternalContext().getSession(true);
Enumeration<String> keys = httpsession.getAttributeNames();

String captchaValue = null;
while (keys.hasMoreElements())
{
String key = (String)keys.nextElement();
if(key.contains(SESSION_KEY_NAME))
captchaValue = (String) httpsession.getAttribute(key);
}

if (captchaValue.equalsIgnoreCase(value)) {
//... your validations here...
}
