Michael,
As Steven said, I would recommend doing this declaratively.
Do you have a model action on your ‘account’ model that runs when the ‘meeting lookup’ field is populated? I’d guess that your action is doing a query to get your meeting record data. Since you populated the lookup with Skuid generated id (and not a ‘real’ meeting Id), I think that your model de-activates the Id condition and attempts to load to whatever limit you have on your model (presumably no limit).
Try moving the action to update the ‘account’ model to the save button on your new meeting popup. This way you will get a ‘real’ Id set on the ‘account’ record. Make sure you save your new meeting, then update the ‘account’ model.
Thanks,
Bill
