Description Ian Springer 2012-04-06 11:17:39 EDT
Currently if existing ResourceTypes are updated as part of a plugin update, the updates do not get picked up by the GUI, because the GUI's cache contains the old types. This is fine, except the only way for the user to get the types updated in the GUI except is to do a hard browser refresh. This is not very intuitive and causes the user to have to wait several seconds for the page to load. Logging out should also clear the type cache. Then we can say in the documentation, "if you update any Agent plugins, to pick up the changes in the GUI, log out and then log back in.

Not sure I agree that the cache should be cleared on log out, since changes to 
ResourceTypes should in general be pretty rare in production deployments, e.g. 
upgrading to new JON versions, patches, new customer developed plugins. It 
seems a waste to have people download that extra data (presumably is a lot?) on 
every login. I agree its not great that it requires a hard refresh right now, 
this is less good because not every user is going to know that they need to do 

I would say we need a way to invalidate the ResourceType cache in the browser 
when it needs to be updated, rather than a blanket cache eviction policy.

Closing this.  If and when we get server2gui notification we'll take care of this as part of that work.
