Hi, I had the same problem once. After a lot of investigation, turned out this was due to the <html:base> tag and the way I used tiles.
In any case, check the value of the <html:base> tag in the final HTML code. It might point to one of your actions. Some browser send a request to it to check if the base URL actually exists (such as Firefox and co.), causing the action to be called more than once. It might have nothing to do with your problem at all, but checking won't take long. -----Message d'origine----- De : Owen Berry [mailto:[EMAIL PROTECTED] Envoyé : lundi 15 novembre 2004 23:18 À : Struts Users Mailing List Objet : Re: Actions being executed twice Good suggestion. I didn't think this was happening as there are different thread descriptors in my logs, but I thought I would try something to test this theory, just in case. Printing something out on System.out should verify that this is not a logging problem, right? Well, it still looks like the action is being called twice - printed the date and time and a message out twice for each execution. Something interesting that I did note is that about 1 in 20 times the action is only called once. Almost looks like a race condition. Thanks for the suggestion. Will post more details of the configuration files tomorrow morning (have to dash now), but it really is not much more than what I detailed in my original email - the action is currently a stub for future use.
