Please see the changelog entry for this method and getObject() implementation :)

Ok, I see. I did not know the fact that getObject() creates object if field is missing. The sad fact is that it sort of counters the effect of remove upon the first check of this property. Looks like we might be better off with replacing a call to remove() with setting the field to an empty object.

I'd suggest the following refactoring that would make things even better: structure state so that instead of holding all agents' states in a single flat m_properties map, it would have an object property per agent. The resetting the state of a particular agent would be as simple as resetting its state object (or replacing it with new blank object). Such refactoring would require InspectorController to shard state object and pass individual InspectorState into each of the agents.

This should be OwnPtr<InspectorState> or you can inline this.

InspectorCompositeStateCookie -> inspectorCompositeStateCookie

The main part of this change is about introduction of a composite state that allows to avoid name collisions, we should probably rename the bug.

[Alexander Pavlov (apavlov)]

The change in its current variation allows to get rid of agent-specific prefix hacks for state property names.
