[Pyobjc-dev] signal 11 when trying to access an NSComboBox's data source

[Steven D. A. <st...@ne...>]

Hi,

I am writing a program which has a controller object with an awakeFromNib
function that begins like this:

    def awakeFromNib( self ):
        self.word_type.setDataSource_( WordTypeManager.alloc().init( self.db
) )
        print "will this fail?"
        print "value = %s" % self.word_type.dataSource()
        print "no, it worked"

The program dies on a signal 11 on the line where it attempts to print the
data source.  We never see the "value =" text or the "no, it worked" string.

WordTypeManager is a class that is declared like this:

class WordTypeManager( Foundation.NSObject, AppKit.NSComboBoxDataSource,
ListManager ):

    def init( self, db ):

    def numberOfItemsInComboBox_( self, comboBox ):
        
    def comboBox_objectValueForItemAtIndex_( self, comboBox, index ):
        
    def comboBox_indexOfItemWithStringValue_( self, comboBox, str_value ):

I can provide more detail about the code if needed.

I have verified that self.word_type is an NSComboBox and that the class's
outlet is connected to the right object in Interface Builder.

I am using Python 2.3 (final) and PyObjC 1.0b1 (not CVS).  Note that I
recently upgraded both Python and PyObjC, and the program worked fine before
this upgrade, although I last used the program a couple months ago.  I am on
Mac OS X 10.2.6, on a dual-processor 1 GHz machine.

Any ideas what might be causing this problem?
