[Yanel-dev] Assigning new group to a user at runtime

[Michael Wechner]

also please note that I have cleaned the code quite a bit by =

centralizing the usage of IdentityMap:

grep -rl IdentityMap src/*
src/contributions/resources/sessionmanager/src/java/org/wyona/yanel/impl/re=
sources/sessionmanager/SessionManagerResource.java
src/webapp/src/java/org/wyona/yanel/servlet/IdentityMap.java
src/webapp/src/java/org/wyona/yanel/servlet/YanelServlet.java

whereas I need to check on SessionManagerResource.java and if this can =

also be improved.

Cheers

Michael
