Issue Summary
Sometimes a Page Properties Report macro throws an exception while sorting. There is a Comparator that is violating its general contract which most likely means it isn't upholding transitivity when sorting the page properties.
Steps to Reproduce
The exact values needed to reproduce are still unknown, and will likely need to be reverse-engineered by looking at the Comparator class. The best method as of now is as follows:
- Create many pages with page properties with at least one column that has primarily datetime objects. Label all the pages.
- Use the page properties report macro and report on the pages, be sure to use the macro configuration options and set to sort by your column that contains mostly dates.
Expected Results
No issue with sorting.
Actual Results
Error on page:
