RE: Making ExternalLink invisible: test for what?
It's an anonymous class and I don't create an identifier for it but I
suppose I can still use:
add(new ExternalLink(..,..,..).setVisible(condition));
"Back in my day we didn't need Tapestry, or Wicket or WebObjects, or
even Servlets, or for that matter Java! We just coded in plain assembly
language. And before that we had to just type in 1's and 0's. Sometimes
we didn't even have 1's. I once had to code for an entire month,
barefoot, in the dead of winter, using just 0's... but you didn't hear
me complaining."

Re: Making ExternalLink invisible: test for what?
why not use the setVisible method?
link.setVisible(StringUtils.isNotBlank(url) && StringUtils.isNotBlank(...));

Re: Making ExternalLink invisible: test for what?
please look at the code, they are called gethref() and getlabel() and return
exactly what you put into the constructor

Thanks Igor, but what are they called? getUrl(), getDisplay()?
Actually the display text is more valuable because it doesn't have the
http:// prefix so I can do a simple null or blank text whereas the URL
will always have a http:// in front of it making a trivial test not
possible.
