#623 Unexpected error in v1.4.4

Frank Edwards

Got a crash. Was playing up to this point (PGN: 1.d4 d5 2.Nc3 Nf6 3.Bf4 a6 4.f3 h6 5.e4 dxe4 6.fxe4 Nc6 7.Nf3 e6 8.a3 Nh5 9.Be3 Be7 10.d5 Na5 11.b4 exd5 12.exd5 Nc6 13.dxc6 bxc6 14.Nd4 Bd7 15.Qxh5 Bf6 16.Bc4 O-O 17.Rd1 Qe8 18.Kf2 Qc8 19.h3 Qd8 20.Bxh6 Bxd4+) and hit the MoveNow button and got an "unexpected" error.

I had been playing around with José as this is my first use. I was making moves by graphically dragging pieces, then undoing them and trying other moves. Sometimes I was using MoveNow and other times I would drag pieces into place.

I don't know if it's related, but I would sometimes be unable to drag a piece after making a move: I hit MoveNow and it moves, but I can't drag a piece of the opposite color. However, if I hit MoveNow again (so the opposite color moves) I can then Undo the move and now I can choose which piece to move myself. (Seems like a boolean flag that allows/disallows the mouse from dragging is not being reset properly. The mouse cursor wasn't changing either, although it flickered to the 'drag' state at the edge of the piece. t didn't try typing in moves in the PGN/Game window to see if that would have worked.)

    Added error.log as an attachment. I see now that it's a NPE. Given the stack trace I'd say it's unrelated to the inability to move a piece (see last paragraph of original report).
