Comment 5 for bug 1789982

This is because of a combination of things, beginning with the fact that the type attribute for these fields is number rather than text. Deposit and acq cost can cause the same issues, even though cost initially appears blank. (If you enter anything into the cost field and then empty it the save will fail for the same reason.) The real fix for this is to just stop using number and make all of these fields text with a validator to only allow entries that look like prices. Branch on the way. Something else that needs to be addressed sometime: there's obviously a part of the save process that assumes nothing can ever fail and blindly charges ahead with closing the window and losing your work.
