Problem with ShoppingCart.tpl refresh

texte = I'm using a modified version of the Tea Room ShoppingCart.tpl page to display a shopping cart both as an item is added, and as they are removed from a cart (here the Remove command calls ShoppingCart.tpl recursively, as in the example).However, the page doesn't always display the correct information, and requires a refresh or a call to a ShowCart link to show the proper contents of the cart. For example, when I add an item, it calls ShoppingCart.tpl but doesn't display the recent addition unless I click on a View your cart link---then the new item displays. Ditto for Remove this item; it doesn't update to show the item gone.I tried adding the [setmimeheader] items someone posted yesterday on an unrelated matter to keep the user's browser from caching, but this hasn't made a difference. > [SETMIMEHEADER name=Pragma&value=no-cache] > [SETMIMEHEADER name=Expires&value=Thu, 01 Dec 1994 16:00:00 GMT] > [SETMIMEHEADER name=Cache-Control&value=max-age=0]I also tried adding xxx=[random][random][random]...Feel free to try this at: http://www.copernicusbooks.comAdd an item; the ShoppingCart page will show nothing is available; click on VIEW CART in the left toolbar and the showcart command will display the proper info.Now, my there is nothing in your cart is based on this test: [orderfile cart=[cart]] [showif [numlineitems]>0] Is this what's screwing me up? If so, why? And is there an easier way to test for an empty cart?Thanks in advance!Kevin Lippert ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
