--- Comment #2 from sfis...@gmail.com --- PJF: to be fair, there are use cases where the spreadsheet being processed by POI is treated as a System of Record, requiring POI to exercise calculations after inputs are modified. DR: part of what PJF is alluding to still holds though. i ran across the same issue sometime ago, and submitted a PR with the added functionality added. what you have come across is the generic "not yet implemented" error that occurs when POI exercises a function that has not been implemented yet. there are two ways to attack this: 1) there is a mechanism to "patch" the functional dictionary at runtime. you can do this but depending on the function in question, it can require a fair bit of baggage code (some of the functions rely on package protected/private semantics which i found infuriating, but that is a discussion for another day with a beer in hand) 2) you can submit a PR and have someone (more than likely PJF) review and merge. caveat emptor YMMV void where prohibited by law past gains are no guarantee of future returns -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
