This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
This appears to be the realm of either the ScopeInterceptor or the SpringWebflow plugin, but I'm having difficulty in finding tutorials or example code other than that cwiki.apache.org/S2PLUGINS (and the car insurance example mentioned by the SpringWebflow plugin, is not shipped with the download.) to help me decide which of these, if either, I should use. I'd be grateful for any pointers or suggestions.
In addition, since research suggests that it is practically impossible to prevent, I need to be able to handle the situation where, after establishing the session, the user opens multiple browser tabs into my app and runs multiple functions at the same time, for example, starts editing orders for two different customers in two seperate tabs. How do I keep "session data" seperate for the two tabs and stop these actions from walking all over each other.
And my final use case, is that I have one other "activity" that *absolutely must* be a session singleton. That is, it cannot start if the user is running another action, and while it's active, the user cannot start another action. What techniques/patterns is everyone using to handle this?
