Application crashes with assert failure when closing the window with TableView scrolled to the bottom
When the application window is closed, it crashes with the following assertion failure:
ASSERT: "m_qmlContext && m_qmlContext->isValid()" in file C:\Users\qt\work\qt\qtdeclarative\src\qmlmodels\qqmltableinstancemodel.cpp, line 125
This issue is observed specifically when there is a header present on the Page, and the TableView is scrolled to the bottom, either using contentY: Math.max(0, contentHeight - height) or manually by the user.
Notes:
- The issue does not occur if the header is removed or its height is changed to 38, for example.
- The issue also does not occur if the TableView is not scrolled to the bottom.
- The issue could only be reproduced on Windows. It does not reproduce on macOS.
Code to Reproduce:
import QtQuick import QtQuick.Controls ApplicationWindow { width: 720 height: 480 visible: true Page { anchors.fill: parent header: Rectangle { height: 40 color: "red" } TableView { anchors.fill: parent model: 15 contentY: Math.max(0, contentHeight - height) contentHeight: 40 * rows rowHeightProvider: () => 40 columnWidthProvider: () => 200 delegate : Rectangle { width: 40; height: 40; color: "green" Text { anchors.fill: parent text: index } } } } }
