[MacRuby-devel] My class's initialize not called

[steve ross]

So, this class doesn't reopen a Cocoa class, it subclasses it. Same anyhow? The real problem is that the class is instantiated as a side effect of nib loading, and the only place I've been able to successfully set initial state is awakeFromNib. I either can't, or don't know how to make the nib load process call a DuplicateCounterTextField.initWithSomeCoolState method. My impression is that awakeFromNib is a poor place for setting initial state because the order in which awakeFromNib's are called is undefined (or is it?). Not to overcomplicate things, but the controller needs to be able to tweak the state of the control -- for example, to change the splitter regex.

Thanks for helping out here.
