Chris, I tested this puzzle in SE 6.30.294 at 2024-03-23 11:15 (GMT+10) and "not valid" is not repeatable there. I'm sorry. I can't say that it's fixed, because I cannot repeat the problem to identify the root cause, but it does appear to be fixed in the latest release. Ergo, whatever I got wrong I now have right, apparently, by happy accident. I'll take it, but please repeat the test in the latest version. It is possible that the root cause is environmental. SE relies heavily on bitwise operations,...
DiufSudoku_V6_30.111 NullPointerException
Fixed in the previous release, I just couldn't work-out how to close the ticket. Good programmer. Bad user. sigh.
HoDoKu.2.4.2 Exception
Fixed. Yep, when you rename a Swing control in Nutbeans it renames the control, and renames the call to the property, but doesn't rename the property in the properties file, so one should NEVER rename any bloody thing in Nutbeans.
I've just released. I think I must have sideswiped this with a global search and replace because "shark" is my work for the Sudoku communities concept of cannibalistic, which is way too long, and I can't spell it. Sorry!
Yep. My bad. Press F5 instead. That works. I never use the GUI because (having re/written it all) I know all the shortcut keys. Sorry. Next release. Give it a couple of weeks.
Thanks for raising it. I'll dig out my HoDoKu code and fix it. To be honest I never used or tested any of HoDoKu's GUI features. I just presumed they all worked and left them alone. So next SE release I expect I'll drop a new HoDoKu as well... usually every couple of weeks. I don't have an internet connection. Cheers. Keith.
