Well, I found a better fix, but it requires an update of Dove.
Basically, what is needed that Dove passes additional information on the binary field (I went for 'size').
The wizard can then test whether a binary field had data by checking the 'size' attribute.
What do people think? Would this be a bugfix or a hack? And should I add this to 1.8, to 1.7.2 ?
