It looks like a problem with your taglib.tld file. Could you paste it in for us? Cheers Simon

What this means is that the PagerTagExtraInfo class is validating the attributes and returning false.
Check the values that you are using against those expected by the tag itself, and also that they are positive integers (as tested by the validInt method). Hope that helps Simon [This message has been edited by Simon Brown (edited September 03, 2001).]
