The onsubmit is adding a friend to XCP. An Ajax call decorator is then
displaying a message on the client side... so the page doesnt change. Here
is the link:
AjaxLink addFriend = new AjaxLink("addFriend")
{
@Override
protected boolean getStatelessHint()
{
return true;
}
private static final long serialVersionUID = 1L;
public void onClick(AjaxRequestTarget request)
{
makeFriends(sessionUserName, profileUserName);
}
protected IAjaxCallDecorator getAjaxCallDecorator()
{
return new AjaxCallDecorator()
{
private static final long
serialVersionUID = 1L;
@Override
public CharSequence
decorateScript(CharSequence script)
{
return
super.decorateScript(script);
}
@Override
public CharSequence
decorateOnSuccessScript(CharSequence script)
{
script = getSuccess() + script;
return
super.decorateScript(script);
}
@Override
public CharSequence
decorateOnFailureScript(CharSequence script)
{
script = getFailure() + script;
return
super.decorateScript(script);
}
private String getSuccess()
{
return "friended('addFriend','A
friendship request was sent.');";
}
private String getFailure()
{
return "friendingFailed('Sorry,
we were unable to send your friendship
request. Please try again later.');";
}
};
};
};
