CPTextField's becomeFirstResponder

#29

There's a slight problem with CPTextField's becomeFirstResponder. For example, in the attached code, when the page first loads and you type something and press enter, there's no data in the Javascript alert. When you click on the text field with your mouse, the field mysteriously deletes the text and then what ever you type in appears in the Javascript alert.

Also, when setEditable is not explicitly set to YES and you use becomeFirstResponder, the field becomes semi-editable in the sense that you can edit the text field but you can't submit the data.

    Alright, the problem here is that you're not supposed to manually call becomeFirstResponder. In order to make a view the first responder, you're supposed to do something like

    [myWindow makeFirstResponder:someView];

    So, becomeFirstResponder wasn't expecting to be called directly. The reason it doesn't work is that it shouldn't be allowed to be first responder if it isn't editable, and you hadn't made it editable yet.

    So, if you make it editable, add it to the window, and after that call:

    
	[[textField window] makeFirstResponder:textField];

    Then, it should work as expected.
