Hi there ..
Setup a panel that covers both, a facebook-login button and a user state
sensitive link.
The link should be disabled unless we find a user in the session.
The Ajax FB link looks like:
AjaxLink fbLink = new AjaxLink("fb") {
public void onClick(AjaxRequestTarget target) {
getPage().getRequestCycle().scheduleRequestHandlerAfterCurrent(new
RedirectRequestHandler("http://www.facebook.com/login.php?api_key="; +
pcs.getFbApiKey() + "&v=1.0"));
}
};
add(fbLink).setEnabled(session.getAttribute("user") == null);
It works like a charm.
The link looks like:
adminPageLink = new Link("adminLink",model) {
public void onClick() {
setResponsePage(new HomeAdminPage());
}
protected void onConfigure() {
LOG.debug("onConfigure");
setVisible(session.getAttribute("user") != null);
}
};
add(adminPageLink);
This link is properly rendered as long as the FB login page has not been
called and returned.
Once the user is properly logged into FB, the adminLink is not clickable (no
tag is rendered)
Im still quite new to Wicket and any help your be appreciated.
Best regards
Thorsten
