Can you give us a little more context? Does the rendered state of the shopping cart correspond to its actual contents?

In vanilla seaside, this should be true. The conponent should be re- rendered when you press the back button. What you are seeing might be "desired" behavior. Back in 2005, we all went nuts about continuations and the fact that the back button finally works right in seaside ;-) our definition of consistency was somewhat different from the rest of the world's...

So I suggest to try the following:

1. Put a halt or breakpoint into the component's rendercontentOn: to see if it re-renders

2, render an inspect link into the component to see if what the component shows is what the cart contains. All you need is an anchor with a callback like this: callback: [myCart inspect]

The basic question IMO is what your definition of "consistent" is and whether you expect the right thing to happen.

The chrome differences In behavior should be addressed right next after that.

So chrome requests are probably
