Hello Jean,

thank you for the update.

We have one issue, which appeared in the customer application. There was an unexpected exception IllegalArgumentException caused by the Keikai's formatting logic. Unfortunately I can't replicate the issue and the only evidence I have is an error message and the related call stack from the time the error happened:

Although the log output above would suggest that the format " [RED] -##,###,##0.00" is invalid, in a simple test case it works OK. By simple test case I mean I can assign this exact format string to a cell using the Keikai API.

Perhaps you have seen this kind of error previously? The Keikai version is 5.7.0.

Thanks,
Hynek

The Keikai ticket for this issue is https://potix.freshdesk.com/support/tickets/12479. They suggest to trim the white spaces from the format string, which should work for us OK.

I checked in the suggested workaround in 3821c revision 12399.
