While debugging I noticed that a custom object's set method is being
invoked twice. I have theViewController that is the files owner of my
Nib. theViewController has a myObject property. myObject is bound in
the Nib using an NSObjectController to the file's owner's myObject
property. Automatically prepares content is unchecked in IB. In
theViewController I override setMyObject to do some prep work, I also
call [super setMyObject:sender] first as that is where the myObject
property is defined.
When I load the window and thus the view everything works fine but all
of the methods I perform in setMyObject show up twice when I log them.
I have been trying to track down where I might be sending setMyObject
twice, but am baffled. Here is the log output
2009-05-12 08:50:23.229 myApp[21135:10b] SVController BEFORE adding
DetailController view to SV
2009-05-12 08:50:23.281 myApp[21135:10b] SENDER = <TKProductGroup:
0x12d7a50>
2009-05-12 08:50:23.283 myApp[21135:10b] myIDAttributeSet = (null) ::
(null)
2009-05-12 08:50:23.322 myApp[21135:10b] SVController AFTER adding
DetailController view to SV
2009-05-12 08:50:23.324 myApp[21135:10b] SENDER = <TKProductGroup:
0x10afed0>
2009-05-12 08:50:23.324 myApp[21135:10b] myIDAttributeSet = (null) ::
(null)
I know this question is pretty difficult to answer without seeing all
of the code, but wanted to ask in case this is a normal bindings issue
and nothing to worry about OR if it is a sign of something serious
screwed up in my code and thus needing further attention.
Thanks
Chris
