Rebuild Cache

Whenever a structural change to a station is made, by adding or removing a Component or History, we must invoke invokes an action on the NHaystackService called rebuildCache. By invoking rebuildCache, it causes the NHaystack Server to traverse through the entire station and rebuild all of its internal data structures, so it can keep track of how everything in the station is interrelated. Its best to just get in the habit of running it any time you change a tag or alter the structure of a station.

This can be executed in either FIN Stack or Niagara. Look below.
