Browser caches user authorities when using Waffle security

When using Waffle security (with Spring security, in my case) I discovered that both Internet Explorer (9) and Firefox (5) caches authorities bounded to user. I discovered this when I’ve chagned required user group to access my application and then I added current user to required group but no change. I couldn’t gain access. After some debugging it appeared that Waffle returns unchanged set of authorities for current user.
Reloading browser, tomcat and clearing all caches and data didn’t work. I’m sure that Chrome would work neither.
Firefox has convenient way to clear active logins. Click Tools-> Clear recent history -> [check]active logins

Finally I got the solution – user should logout and login again into windows box…

Context menu or Action buttons ?

Recently I was drawn into one of those UI "religious" disputes that has no easy answers and usually both sides are right. One of our web developers was trying out new web tech (with pretty rich widget library) and started to question himself about some basic usability decisions. The low level problem in this case is usually brought to "which widget should I use ?". I'm not fond of bringing the usability problems to questions: Should I use Tabs over Menu ? Or should I use Context menu instead of buttons panel ? But sometimes if time is crucial factor and other usability levels are by default not addressed at all - better developer that asks those basic questions than developer that do not question himself at all.
