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." > -----Original Message----- > From: Martijn Dashorst [mailto:[EMAIL PROTECTED] > Sent: Wednesday, 3 October 2007 4:36 PM > To: [email protected] > Subject: Re: Making ExternalLink invisible: test for what? > > why not use the setVisible method? > > link.setVisible(StringUtils.isNotBlank(url) && > StringUtils.isNotBlank(...)); > > Martijn > > On 10/3/07, Chris Colman <[EMAIL PROTECTED]> wrote: > > I have content that I render that may or may not have a URL associated > > with it.
