Bug ID: 65289 Summary: XSSFWorkbook.cloneSheet leading to save prompt by Excel without any changes done Product: POI Version: 4.1.2-FINAL Hardware: PC Status: NEW Severity: normal Priority: P2 Component: XSSF Assignee: dev@poi.apache.org Reporter: majorconce...@t-online.de Target Milestone: --- Created attachment 37848 --> https://bz.apache.org/bugzilla/attachment.cgi?id=37848&action=edit Code to reproduce the issue Hi, I have the following scenario: I am opening an excel file using POI, perform a cloneSheet operation on the first sheet and save the file under a new name. When opening the newly created file using Excel 365, a save prompt occurs on closing the file, although no changes have been done. The save prompt asks me to save changes that have occurred. This is quite annoying for everyone who just wants to look into the file. Also it doesn't make sense and seems to be some kind of bug by POI or Excel. But even if this whould be an Excel bug, it would be great if POI would find a way to prevent it. This has been tested using a newly created empty file. If you would like to reproduce the observation, you could use the attached class "Test.java". After having let it run you would open the newly created file by Excel - see below - and immediately close it. You would be prompted to save changes. Prerequisites are an existent folder "c:/temp" and an empty excel file named "test.xlsx" in there. The newly created file will be named "test_copy.xlsx". You may change path and file names according to your suits. You also need at least Java 1.8 and Excel 365. -- 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
