Does anyone have any experience applying watch bindings to items that
are paged and throw IPEs?

I have a managed object that has relationships to other managed
objects. I want to perform operations on the related items when they
are pulled client side (from DGs or other view controls) and any time
they change (from this client or another); so in the constructor I have:

ChangeWatcher.watch(this, ["auxUserData", "techMinInc"],
onTechMinIncChange);

Where *this is a managed object and techMinInc is a property on the
related auxUserData managed object.

This throws an IPE from ConcreteDataService and it's not catchable here.

Must I first finger auxUserData, catch and handle the IPE before
applying the watch? Or does anyone have a best practice approach to
this type of problem.
