[seam-dev] How to store data in contexts
Dan and Shane raised the issue of how to store data directly in a
context. 299 includes that facility:
@Current Manager manager;
public void go(final String something) {
// Store the String something in the session context
Contextual<String> somethingContextual = new
Contextual<String>() {
public String create(CreationalContext<String> arg0) {
System.out.println("Storing " + something + " in a
context");
return something;
}
public void destroy(String arg0) {
System.out.println("Removing " + something + " from a
context");
}
};
manager.getContext(ApplicationScoped.class).get(somethingContextual,
new CreationalContext<String>() {
public void push(String arg0) {
// No-op, we don't need to deal with partially
circularities here
}
});
}
But often, if you are controlling the data object, it's better to use
a bean to manage the data.
