Hi all,
I am using a from: transformed: at some point, and I just got the transformation block being called with a nil value when the from pane gets a selection of nothing. my showOn: block does not state allowNil, so I did not expect this to happen. Is it expected that transformation blocks always check for nil-ness of their arguments?
