--- Comment #3 from Andreas Beeker <kiwiwi...@apache.org> --- We have unit test to check if successive changes are saved to disc - just look for the many invocations of "writeOutAndReadBack" in the test classes. So there was someone who did a detailed analysis for such cases. Therefore you need to put more detail in your bug report before we can analyze it. Something like adding ... * an attachment of your first save * modifications from first to second save - preferably as junit test * an attachment of your second save * describe what content you still expect to be there - i.e. what has been lost? Be aware that POI is not keeping track of the content of the file. Once it's read into memory - especially if you modified those parts - those parts will be cached and not read again. So if you would like to react on external modifications, you'll need to verify the file timestamps yourself and reload the workbook. -- 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
