Object generating expression fields cause cyclical evaluations

[Skaiir]

Describe the Bug

When we define an expression that results in an object, it causes an infinite loop of evaluation.

Steps to Reproduce

1. build a form with at least two onChange expression components where the expressions evaluate to objects
2. put a breakpoint in the onChange event listener in the expression component
3. the event listener executes forever

Expected Behavior

3. the event listener should not execute multiple times
