Error with a custom floating point column.

ERROR MESSAGE
calibre, version 0.8.4
ERROR: Unhandled exception: <b>TypeError</b>:QDoubleSpinBox.setValue(float): argument 1 has unexpected type 'NoneType'

Traceback (most recent call last):

TypeError: QDoubleSpinBox.setValue(float): argument 1 has unexpected type 'NoneType'

I'm running Windows Vista Home Premium 64-bit. Calibre version 0.8.4.

I just updated about an hour ago and when I went to add a rating to a few books (in the custom column), I received the above error message. After I close out of the message, it lets me add the rating like normal. If I try to change an existing rating, I have no error messages or problems.

This isn't a big deal for me because I'm still able to save the ratings and whatnot, I just figured I would let you know. Thank you for such an amazing program!! :-)

Workaround: use edit metadata (single) to set a value. Once it has a value, it can be edited from the library view.

I'm sorry, I might not have been clear when I posted it because I was in a rush. It can be edited from the library view without a pre-existing value, you just have to close out of the error message first.

[Charles Haley (cbhaley)]

You are correct, but that is an accident. I can imagine some situations where you would not be able to continue editing.

Fixed in branch lp:calibre. The fix will be in the next release. calibre is usually released every Friday.
