--- Comment #3 from Greg Woolsey <greg.wool...@gmail.com> --- I'll take a look, as this will likely affect me too. Extension elements are typically for features added to Excel after the initial spec. POI generally doesn't do much if anything directly with them, so handling these may involve new API methods to avoid changing behavior for current ones. I have at least one project which expects the method you point out to only return validations defined for the current sheet, we try to avoid API changes that break the contract of previous versions, when possible. -- 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
