Well, I was using this tag earlier in the week. (We've been trying to stay away from any Struts specific tags until recently too - we're locked in now anyway, so we might as well).
It seemed when I was setting errors, the jsp I forwarded to would not show them. I tried adding a message, and then both were shown. I came to the conclusion (maybe I little rashly) that 'messagesPresent' solely checked for messages; upon reading that snippet of the docs, it appears i'm wrong. I did actually attempt to use the tag with <logic: messagesPresent messages="false|true"> in the hope that I could modify the behaviour, but to no avail. I think i'll grab the logic tag source and work out what is *actually* happening here ;) Cheers, James. -----Original Message----- From: Riyad Kalla [mailto:[EMAIL PROTECTED] Sent: Wed 6/9/2004 7:18 AM To: Struts Users Mailing List Cc: Subject: Re: how to check if html:errors will display anything James, I can relate completely to the desire to not have scriplets.. However today is your lucky day, because logic:messagesPresent's defintiion is to actually check for ActionMessages, ActionErrors and a few other things, def: "Evaluates the nested body content of this tag if an ActionMessages object, ActionErrors object, a String, or a String array is in request scope. If such a bean is not found, nothing will be rendered." from here: http://jakarta.apache.org/struts/userGuide/struts-logic.html#messagesPresent so it seems that does what you need it to?
