I am using Spring Webflow 1.0. There is only one root flow without any subflows. There are 5 pages in the flow so, 5 controllers are being used in the whole flow. When i terminate the flow with an end state, and go back to the flow again, I can see the variables set by a controller during previous flow, which are not even in any scope but they were variables of a controller which still exist even after end of the flow. What is the reason? is it a bug?
