> I have had this happen to me before, but I don't recall why.  Logging out a stack trace (or setting a breakpoint if you are feeling modern) when setQtyForSynthManifestTransaction is called with a null value is the quickest way to solve this.

It's the exact same stack trace:

Now, if I submit the form, setQtyForSynthManifestTransaction is called with the value that I submitted, that's fine, but the setter is called a second time, and it sets the value to null, so when createSyntheticTransactionFromSpec or createSyntheticTransactionFromPart are finally called, the quantity is set to null!

After the first awake, setQtyForSynthManifestTransaction is called to the correct value, after than awake() is called a couple of times and boum! setQtyForSynthManifestTransaction is called with a null value!
