Symptom: executing MDL that describes an empty change-object activity could create a model that fails Studio Pro validation with CE0032 because the action had no items and did not commit the object. Root cause: the MDL syntax represents an empty change action as `change $Object;`, but the builder always wrote RefreshInClient=false for change-object actions. For an empty non-committing change, Studio Pro requires the refresh flag to make the activity valid. Fix: set RefreshInClient=true when building a change-object action with no member changes. Change actions with explicit member assignments keep their previous refresh behavior. Tests: add a builder regression test that constructs an empty change statement and asserts that the resulting ChangeObjectAction refreshes in client.
Symptom: the empty change-object fix relies on RefreshInClient=true even though the CE0032 text mentions only missing items and commit state. Root cause: the Studio Pro validator accepts refresh-only empty changes, but that behavior is not obvious from public docs or the CE0032 wording. Fix: add an executable bug-test fixture for issue mendixlabs#339 and document the mx check behavior directly beside the builder inference. Tests: `./bin/mxcli check mdl-examples/bug-tests/339-empty-change-refresh-in-client.mdl` and `go test ./mdl/executor -run TestEmptyChangeObjectRefreshesInClient`.

Summary

An empty, non-committing
ChangeObjectActionwithout refresh is invalid in Studio Pro and reports CE0032. Existing models can use empty change activities as refresh-only actions, and the MDL form currently has no explicitrefreshmodifier forchangestatements, so the builder needs to preserve validity by inferring refresh for empty changes.Validation
