Why won't this work!?

Hi!

  Sometimes I really think I should change business!

  I have this binding:

ShowDowndloadsConditional: WOConditional {
	condition = downloads.isEmpty;
	negate = true;
}

  "downloads" is an NSArray.

  When running, I get this:

Reason: <my.top.secret.package.name.ExportDownloadItem 0xb95569> valueForKey (): lookup of unknown key: 'isEmpty'. This class does not have an instance variable of the name isEmpty or _isEmpty, nor a method of the name isEmpty, _isEmpty, getIsEmpty, or _getIsEmpty

  The ExportDownloadItem is an object in the array.

  My question is... why!?!?!? :)

If I do this the dull way (write a method that returns downloads.isEmpty() ) and bind to it, this works.

  Yours

Miguel Arroz
