Exporting files as a compressed archive may throw an exception if done from a subdirectory

Here is the stacktrace:

org.hibernate.LazyInitializationException: could not initialize proxy - no Session

This happens because the path up to the root directory has not been loaded. It may work sometimes if all info happens to be in the cache. Simpe solution is to reload the directory with the current session.
