Trying to figure out session properties mechanism for the following example scenario (as was demonstrated on the business dashboarding webinar). Assume you have an ecommerce website and you wish to use the user session query to display how much revenue is at stake per APDEX category.
The basket amount can be either retrieved from the server side return value of a function or from the web ui by using a css selector on the field displaying the basket amount (it is displayed at all times and not only on checkout).
My question is how does session properties being evaluated and updated ? are they only set the first time it sees a value or is it continuous ?
How would you implement such usage ?
Only the last orderID will be shown? Is it possible to be appended to the already captured OrderIDs?
