bean:define calls PageContext.setAttribute(), which does return an error if the attribute already exists.
http://java.sun.com/j2ee/j2sdkee/techdocs/api/javax/servlet/jsp/PageContext.html#setAttribute(java.lang.String, java.lang.Object, int) The options seem to be A) Extend bean:define so that it can remove a bean first. B) Create a new tag to remove a bean if it exists (e.g. bean:undefine) C) Use a scriptlet D) Change the ItemList template so that you can pass the name of the item list as a Tiles attribute I'd go with D :) -- Ted Husted, Husted dot Com, Fairport NY USA. -- Building Java web applications with Struts. -- Tel +1 585 737-3463. -- Web http://www.husted.com/struts/ Joćo Guilherme Del Valle wrote: > > Hi, > > I want to replace a bean.
