Re: Highlight current row - Facelets Bug?

[Jeff Bischoff <jb...@klkurz.com>]

Hey Guys,

Can anyone confirm this for me? This highlight row trick works fine in 
JSP, but when I converted my application to Facelets, I get behaviour 
like opick is describing. I'm guessing that is his problem too, though 
he didn't say if he is using facelets or not.

Is this a bug in t:dataTable or facelets?

I was using this trick to highlight selected rows in my app for several 
months, and I really like it. Would love to get it working again, in 
facelets. :)

Regards,
