This is the recommended procedure for the projectdoc Toolbox version 2.0 and up. The procedure for earlier versions is not very different, but recursion detection for references is a feature for display property macros added to 2.0. Users usually do not define recursions, but may do so very rarely unintentionally. Recursions in references are no problem as long as the cache is in place. If the cache is removed, recursions are detected by Confluence on a stack overflow. This may drain on resources until all recursions are resolved. Version 2.0 will detect recursions based on display property macros more quickly and render an error box as a value to the properties instead. |
