Unreal Engine Issues and Bug Tracker (UE-353450)

Description

[Link Removed] was fixed by CL 46990575, successfully avoiding an ensure condition inside FIntervalStructCustomization::SetValue() when its Property Node is no longer valid. However, the same problem also exists with FRangeStructCustomization::OnValueCommitted().

The issue can be reproduced easily by having a BP/C++ Actor or DataAsset that contains both an FRuntimeFloatCurve and an FFloatRange. If the FFloatRange value is committed by pressing Enter in the Details Panel while the FRuntimeFloatCurve editor is visible, the ensure is very likely to trigger (see provided call stack).

This happens because the SCurveEditor widget used by FRuntimeFloatCurve requests a full refresh of the Details Panel when there is a change to any property of its owning asset, according to the following simplified call chains:

FCurveStructCustomization::CustomizeHeader()
SCurveEditor::RegisterToPropertyChangedEvent(OnRootPropertyChanged)

SCurveEditor::OnRootPropertyChanged()
SCurveEditor::RefreshDetailsView()
SWidget::RegisterActiveTimer(<lambda>)

[SCurveEditor]SWidget::Paint()
[SCurveEditor]SWidget::ExecuteActiveTimers()
SCurveEditor::RefreshDetailsView()::lambda
SDetailsView::ForceRefresh()

During the refresh performed above, the Property Editor Row used by FFloatRange/FFloatInterval gets destroyed and recreated. Upon destruction, the editable text field being edited loses focus, triggering an extra commit of its value. This extra commit attempts to set the value to a now-destroyed property, causing the ensure to fire. Simplified call chain:

STreeView::ReGenerateItems()
FWidgetGenerator::OnEndGenerationPass()
FWidgetGenerator::ProcessItemCleanUp()
SDetailsViewBase::OnRowReleasedForDetailTree(DetailSingleItemRow(FloatInterval))
SDetailsViewBase::ClearKeyboardFocusIfWithin(DetailSingleItemRow(FloatInterval))
FSlateApplication::ClearKeyboardFocus(SetDirectly)
FSlateApplication::SetUserFocus({}, SetDirectly)
FSlateEditableTextLayout::HandleFocusLost(SetDirectly)
SEditableText::OnTextCommitted(Default)
OnTextCommittedCallback.ExecuteIfBound(Default)
SSpinBox<NumericType>::TextField_OnTextCommitted(Default)
SSpinBox<NumericType>::CommitValue(CommittedViaTypeIn, Default)
OnValueCommitted.ExecuteIfBound()
FRangeStructCustomization<NumericType>::OnValueCommitted()

The full call stack of the ensure() is also provided.

Ticket was generated from 3rd party UDN Vendor report via Slack-bot and is pending pre-processing.

Steps to Reproduce

1. Create a BP Actor containing both a "FloatRange" and a "RuntimeFloatCurve" variable. (it can also be a C++ Actor or DataAsset)
2. In the BP editor window, select the "Class Defaults" tab
3. In the Details Panel:
3.1. Make sure that the curve editor is visible
3.2. Edit one of the fields of the FloatRange structure
3.3. Commit the change by pressing Enter --> ensure() !
