Lightbox addon doesn't work any more :(

Hi! I am using Pier 1.2 and lightbox doesn't seems to work. I created a simple search widget and embed it into a page like this: ++/seach++ The ligthbox is displayed. Then I type a word and give an enter. At that moment, I get the following walkback: Seaside WalkbackWAComponentsNotFoundError: Components not found while processing callbacks: an Array(a PRSearchWidget) Debug <http://localhost:5555/seaside/pier?_s=BOXmeDNxcV8T5o3T&_k=N3RtmbmB&1> Full Stack<http://localhost:5555/seaside/pier?_s=BOXmeDNxcV8T5o3T&_k=N3RtmbmB&2> Possible Causes - you do not implement #children correctly - you do not backtrack #children correctly - you do not implement #states correctly I am sorry my seaside skill is not yet to good so I don't know what the problem can be. I checked PRSearchWidget but I think they don't need a children or states method. I attach complete SqueakDebug.log Any help? Thanks in advance, Mariano
