Hi,
I come across and issue with the latest Trinidad release and would like to ask
for expert advice.
Below please find a snippet of the code that came with the Trinidad 2 beta
demo. It works well in a jsp JSF page:

However, when I put the same code into a facelet, it doesn't work. And when I
remove the "tr:panelGroupLayout" it would work but I have to click twice on
"Next / Previous" button and on the drop down. On first click it would simply
re-load the page:

What am I doing wrong? Your help is greatly appreciated.
Best regards,
