Schema Output History Debug (Schema History Debug)
The report this view provides lists the recent history of output from a JSON schema.
Figure 35. Schema Output History Debug properties
Right-clicking Schema Output History Debug followed by clicking 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.
