more() needs to be called in order to go forward. You can do something like #set($garbage = $wrapper.more()) to not print the result. But maybe a wantMore() will be a good RFE. ;) > Also I am wondering how a "continue" might be handled.

I would think having > not just a #stop (aka break) would be useful, but a #continue. Actually, #stop stops Velocity, not just #foreach. Using #if is the only solution for a "continue" that I can think of right now. http://jakarta.apache.org/velocity/user-guide.html#Stop Best regards, -- Shinobu -- Shinobu Kawai <[EMAIL PROTECTED]> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
