Does BuildManifest have a reset() method. What is the stack trace when setQtyForSynthManifestTransaction is called with a null value?

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!
