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
