Description

This is applicable to the current master branch, not a released version - specifically pull request #648

See the attached file. Both cells have a conditional formatting rule (red with red text) if the value is > 5. With the latest build using POI 3.17, changing A1 to 6 causes only A1 to be highlighted red, even though B1 ("=A1") is also 6. Subsequently changing A1 back to 5 causes B1 to be highlighted red, even though it's value is 5 again.

Seems to me that the conditional formatting is being evaluated before the formula is - so it's using the old value of the cell.

Tagging @alexberazouski and @WoozyG as I'm not sure if this is a Vaadin Spreadsheet issue or a POI issue.

Research direction

Reproduce the issue with the attached workbook on the current master branch, then inspect pull request #648 and the POI 3.17 integration. Trace the order of formula recalculation and conditional-format evaluation; done means changing A1 between 5 and 6 updates both A1 and B1 highlighting according to their current values.
