Description renau.couture-legare 2016-11-21 15:46:22 UTC
With 3.14, I didn't get this problem, but since I upgraded to 3.15, I've got it.

The documentation about the name we can set to a cell say that we can have a 'period' character as long that it isn't the first character of the string.
When I see the code, there's no validation about that character and it's now throw me an IllegalArgumentException

Either is the documentation on "Name" isn't right or the code has a bug.

Do you have a piece of code that shows the changed behavior? A unit-test would be best so we can more easily reproduce this.

Please see bug 56781 and bug 60246, which were fixed in 3.16 beta 1.

These [1] are the rules that we have attempted to implement. If these rules have not been implemented correctly, then we need to fix it.

I interpreted the following rule to mean that a named range with the name of "." is not allowed. Is this named range allowed in Excel? If so, what versions (file format and application)? If this is the case, either I have misinterpreted this sentence or Microsoft's documentation is incorrect.

No update for quite some time, therefore setting this to WORKSFORME for now, please reopen if you think the current logic in the latest release is still broken.
