Is this the case?Yes, that's probably right. But you could do something to get around this problem ... such as:1- write another file to disk *after* the cart change. 2- use a [waitforfile] context to wait for that extra file to be written.This should make webcat wait until the extra file is created *before* it tries to render the page. Then when the page is finally rendered, it's a pretty good bet that the cart changes have been made, which means those changes should be reflected in the resulting page sent to the browser.Personally I do not use shopping cart files on the webdna sites I create, so I never have this problem -- that's why I didn't think about it when suggesting it to you, sorry. Unless a client absolutely requires it, I generally use my own external eCommerce code, which perform the same tasks faster and more flexibly than webcat's internal code -- and it avoids these and other related issues having to do with cart and order 'files' not being databases, not being searchable, etc.That means I can avoid use cart files, and order files, and all the tags associated with them, such as Add, Clear, Remove, Purchase, ShowCart, OrderFile, SetHeader, LineItems, AddLineItem, ClearLineItems, RemoveLineItem, SetLineItem, NewCart and NewCartSearch. Instead I use standard webdna database calls and all the other NON-eCommerce tags the webdna language offers ... :)Sincerely, Kenneth Grome WebDNA Consultant
