NSPredicateEditorRowTemplate

I have a custom view in a NSPredicateEditorRowTemplate. It seems like the NSPredicateEditor isn't aware when I change the state of the custom view, because when I ask it for the predicate it just returns the old one without even calling predicateWithSubPredicates on my template. I'm guess

Crash after saving document

Hi, In my garbage collected app I'm seeing a crash after saving a document to disk (or any of the other export metods that bring up the save panel). The crash doesn't happen always, but still with some frequency (I can usually get it to reproduce between every 10-20 saves/exports). I _thi

If you've already parsed the text, just use NSNumber's class method +numberWithDouble (or whichever other method is appropriate for your needs). If you don't want to use your own parser, you can use NSScanner on your text, but make sure you've set the locale to correctly interpret the comma.
