Seems to me that when grid was in the class definition, it had to be instantiated earlier, i.e. before any of the events on the form; when it was on the form, it was treated as an object which could be data bound, so it was instantiated after setting up the DE, so when it's init fired in the first place, it fired before the DE, and found no tables at all. Just guessing. What would Sherlock say to this?
