In an Opportunity's "beforeSubmit" I am setting the shippingaddress to a custom address by retrieving the shippingaddress subrecord and setting values on it. Everything works fine, except when the Opportunity is redisplayed after the update, the shipping address still shows the wrong address. But if you edit the record, and click the little pop-out square, the correct address is there. So just the "read only summary label" shows the wrong (old) address. If you do all this manually in the UI, it "triggers" the right update. Anyone know how to trigger NetSuite to update its own summary text field?

Not sure, but is it a sublist value you can set?
