Right-clicking Schema Output History Debug followed by clicking Views > Spy Local or Spy Remote opens a schemaOutputHistoryDebug tab. This tab displays the recent history of output from the schema. This information is useful when the output updates rapidly, such as when a link calls a generate JSON in quick succession, or, in a relative schema, when output quickly changes once per base item.

In addition to the standard property (Enabled), this property supports the Schema Output History Debug component.

Property Value Description
History Max Size number (defaults to 10 records) Sets how many debug records to store in the station.
