[Pyobjc-dev] NSNumber.alloc().initWithFloat_ crashes

[Martina O. <Ma...@Oe...>]

Hi,

Apparently the bridge now tries to translate NSNumber to native python 
types:

Python 2.2 (#1, 07/14/02, 23:25:09)
[GCC Apple cpp-precomp 6.14] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>> from Foundation import *
 >>> n = NSNumber.numberWithFloat_(1.0)
 >>> n
1.0

That's nice, now I can get rid of a lot of stupid floatValue() calls. 
Actually I must remove them, because they no longer work:
 >>> n.floatValue()
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
AttributeError: 'float' object has no attribute 'floatValue'

Even worse, the following snippet crashes python, perhaps because it 
tries to translate an uninitialized NSNumber:

 >>> m = NSNumber.alloc().initWithFloat_(1.0)
