[jboss-user] [JBoss Seam] - Re: Newbei question: Page navigation

[zwu_ca]

 First I am so thankful you are so patient and so willing to help -- very rarely.

  I don't see 'a' anywhere in the original code posting. I forgot to use the 'code' html tag in the original code. There might be some confusion there (you might have different views from mine?). I will try to post the code again here (hopefully this time it can be resolved ).
