servers when it is changed/removed. Removes RemoveByJson as we only actually require RefreshByJson since we can put any sort of parameters
in a custom json string including whether it is a remove operation (if required)
Updating doc type create dialog to verify alias before saving.
Updating ContentTypeRepository to Mandate that the alias is not empty.
Fixes the cause for U4-1976
cleared when media was deleted. Created base classes for cache refreshers, we now have a new event - CacheUpdated
which can now be used by code to execute on each individual server when any cache refresher is updated. Listening to events
normally only fire on the individual server so if people are wanting to refresh their own cache there was previously no way
to do that.
Refactoring ImportDocumentType dialog to import through the PackagingService.
Making a few corrections to the ProppertyGroup and PropertyType classes to support bulk saving.
updates especially when deleting one since we require all sorts of Ids from the object but the object will be deleted by the time
the request reaches other servers so instead we create a json payload to send to other servers which contains all information necessary
to refresh/clear the cache on the other servers. This will probably be the preferred way going forward to handle cache refreshing.
With this in place, when removing a conent type cache is removed based on events.
This also adds a 'class' generic argument constraint to the repository base classes to guarantee we can do null checks and then we also
fix a null check on RepositoryBase. Updates the Entity class to properly support tracking properties - this now allows us to determine if
an entity was new, which is now used to ensure we don't re-update all of the content cache when a new content type is created.
Have also changed the deletion and creation of document types to use the new API, this allows for a lot less processing and streamlining how
all cache is invalidated. Fixes the construction of a new Template and Content Type in the v6 api and ensures that default values are set - #U4-1972, #U4-1971
media types, also ensures that the route cache is cleared (#U4-1969). Changes the deletion of media and
doc types to use the new Api - this ensures that cache is refreshed properly.
