How do you set Session variables? I attempted to do the following.

Session.set('order_id', this.order_id);

But when I went to the cart and attempted to retrieve them with the following code they weren't set.

Session.get('order_id');

Unfortunately the Session module data doesn’t persist between shopping, myaccount, and checkout ssp’s

What would you use to store data between myaccount and checkout? I am implementing edit order functionality. So in my Account they use an Edit Order button within Purchase History. This dumps the items from the order back into the cart. I need to be able to query whether

order_id

is set in checkout to know whether to update an existing order or let checkout proceed normally.

I probably would just contain the edit order functionality to be within myaccount. Mimic the order details page with an editable version, and not use the native cart at all

Yeah the client saw a version like that and was very unsatisfied. I will probably just have to store browser side then. They want the shopper to be able to add new items in. It's a Food Bank and there are a ton of restrictions of what food can go to which agency based on the funding source. I don't want to have to rebuild all that.
