Many may already have realized this, but for anyone who hasn't, I just came
across this elegant way to handle optional emails.
The user/admin stuff is just an example use-case, simplified to fit here.
// User's Statement page lists some items and who bought them...
AbstractLink myLink;
if (isAdminUser()) {
// admins can view the buyer's full info
myLink = new BookmarkablePageLink<MemberPage>("buyer.link",
MemberPage.class, params)
} else {
// normal users get email links to each other instead
myLink = new ExternalLink("buyer.link", email);
// or if they don't have email, just show their name
myLink.setRenderBodyOnly(email.isBlank()); // if they don't have
an email
}
myLink.add(new Label("buyer.name"));
Before I found this, I had two separate elements - the a link with it's span
name inside, and then another span name with only one or the other visible -
that was ugly.
Maybe this helps someone else
Cheers,
Jim
