Stack trace in bb manager

aashideacon · July 12, 2015, 4:55am

Someone posted the song Iron Man, and it won’t play because of an “Accent” error. You can see in the screenshot it says it is “Undefined”. When I clicked the X to delete it I got the following trace:

(I uploaded the erroneous song, and the screenshot of the bb manager song)

What version of the BB Manager are you using? I suspect the iron man song was created using an older version, if that is the case then it makes sharing songs on the forum a nightmare as every time the manager software is updated there will be various issues with older content on the forum.

Wow, this seems to be a cool and nice error Huge thanks for a correct dump!
I’ll investigate this in a moment!

@Psalm40 We’re working on sharing songs to no longer be a nightmare for anyone involved!

[Edit] Yes, this is easy to reproduce. Error handling is obviously the weak side of adding the Undo/Redo functionality…

Daef · July 12, 2015, 11:01am

Damn, this was a really nasty bug!!!
While investigating this, I couldn’t even understand WTF is going on (note, usually I do have a clue!), but I’ve found what seemed to be a totally unrelated bug.

It was a complete surprise to see this issue was fixed as well!
I will update this post as soon as a new download is ready.

…And someone still laughs at the Windows BSOD? At least it is much more stylish and informative than this.

P.s.: All four versions of upcoming BBManager 1.5.0 (it’s 1.5.0.1 now) are uploaded.

aashideacon · July 12, 2015, 4:08pm

I’m using the current version.

Hi where is 1.5.0.1 for Mac so I can download it? Thanx!

Daef · July 12, 2015, 10:34pm
