Description PJ Fanning 2023-06-20 22:46:36 UTC
See https://lists.apache.org/thread/92vvvvwn25sjkbqo0rp8hlnkpb66lb84

reproduction code is in https://github.com/ManiacTwister/poi-table-bisect

A formula like `SUBTOTAL(109,Table1[Heading2])` can get overwritten by POI and become `SUBTOTAL(109,Sheet0!B2:B6)`.

One way to avoid this is to call this API on XSSFWorkbook.

Setting it to false will stop POI rerendering your formulas.

It is suspected that https://github.com/apache/poi/pull/269 may be making this cell formula rerendering worse for this scenario.

Thanks for your effort.

I can confirm using the workaround `setCellFormulaValidation(false)` fixes the problem for my testcase as well as for my real use case.

Let me know if i can help/test anything to fix the issue.

Thanks ManiacTwister. We do need to make POI changes. PR 269 has got some problems.
