Unsolved QtCreator crashing when a particular file is saved
-
I have a fairly big QtQuick project, and I'm trying to work on in with QtCreator (Qt Creator 4.4.1 based on Qt 5.9.2, on Ubuntu 16.04)
On saving one of the files in the project (or sometimes just editing it...) QtCreator crashes completely, and this is fairly consistent.
Running from the command line, I get to see an error dumped to the console as it crashes: here it is in all it's unfathomable glory:Exception: "InvalidModelNodeException" Function: "selectedNodes" File: "/work/build/qt-creator/src/plugins/qmldesigner/designercore/model/model.cpp" Line: 1452 "file: /work/build/qt-creator/src/plugins/qmldesigner/designercore/model/model.cpp, function: selectedNodes, line: 1452" " /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugin/libQmlDesigner.so(_ZN11QmlDesigner9ExceptionC2EiRK10QByteArrayS3_+0xc8) [0x7f613f9c0698] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(_ZN11QmlDesigner25InvalidModelNodeExceptionC1EiRK10QByteArrayS3_+0xe) [0x7f613f9c13ae] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(+0x16089b) [0x7f613f9a589b] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(_ZNK11QmlDesigner12AbstractView26hasSingleSelectedModelNodeEv+0x17) [0x7f613f971827] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(+0x2bddc4) [0x7f613fb02dc4] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(_ZN11QmlDesigner14AbstractAction13updateContextEv+0x3c) [0x7f613fa351bc] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(+0x1efc69) [0x7f613fa34c69] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(+0x15ea58) [0x7f613f9a3a58] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(+0x165c34) [0x7f613f9aac34] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(_ZN11QmlDesigner15VariantProperty26setDynamicTypeNameAndValueERK10QByteArrayRK8QVariant+0x26d) [0x7f613f9c417d] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(+0x1911fe) [0x7f613f9d61fe] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(+0x1940f3) [0x7f613f9d90f3] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(+0x19ad48) [0x7f613f9dfd48] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(+0x19d7c8) [0x7f613f9e27c8] /home/pete/Qt/Tools/QtCreator/lib/qtcreator/plugins/libQmlDesigner.so(_ZN11QmlDesigner12RewriterView12amendQmlTextEv+0x4e) [0x7f613f974a7e] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Core.so.5(_ZN11QMetaObject8activateEP7QObjectiiPPv+0x986) [0x7f615dbbbb96] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Core.so.5(_ZN6QTimer7timeoutENS_14QPrivateSignalE+0x27) [0x7f615dbc8057] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Core.so.5(_ZN6QTimer10timerEventEP11QTimerEvent+0x28) [0x7f615dbc8328] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Core.so.5(_ZN7QObject5eventEP6QEvent+0x7b) [0x7f615dbbc77b] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Widgets.so.5(_ZN19QApplicationPrivate13notify_helperEP7QObjectP6QEvent+0x9c) [0x7f615eeed5ec] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Widgets.so.5(_ZN12QApplication6notifyEP7QObjectP6QEvent+0x227) [0x7f615eef4a17] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Core.so.5(_ZN16QCoreApplication15notifyInternal2EP7QObjectP6QEvent+0x108) [0x7f615db912b8] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Core.so.5(_ZN14QTimerInfoList14activateTimersEv+0x46e) [0x7f615dbe308e] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Core.so.5(+0x2cb8a9) [0x7f615dbe38a9] /lib/x86_64-linux-gnu/libglib-2.0.so.0(g_main_context_dispatch+0x2a7) [0x7f6159709197] /lib/x86_64-linux-gnu/libglib-2.0.so.0(+0x4a3f0) [0x7f61597093f0] /lib/x86_64-linux-gnu/libglib-2.0.so.0(g_main_context_iteration+0x2c) [0x7f615970949c] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Core.so.5(_ZN20QEventDispatcherGlib13processEventsE6QFlagsIN10QEventLoop17ProcessEventsFlagEE+0x5f) [0x7f615dbe3baf] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Core.so.5(_ZN10QEventLoop4execE6QFlagsINS_17ProcessEventsFlagEE+0xea) [0x7f615db8f8aa] /home/pete/Qt/Tools/QtCreator/bin/../lib/Qt/lib/libQt5Core.so.5(_ZN16QCoreApplication4execEv+0x84) [0x7f615db98134] /home/pete/Qt/Tools/QtCreator/bin/qtcreator() [0x409aa7] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf0) [0x7f615c83e830] /home/pete/Qt/Tools/QtCreator/bin/qtcreator() [0x40a401] " terminate called after throwing an instance of 'QmlDesigner::InvalidModelNodeException*' Aborted
The file in question is pretty small - it's meant to be displaying dynamic components with a title bar and a Flickable holding a ColumnLayout to which the dynamic stuff will be added
import QtQuick 2.7 import QtQuick.Layouts 1.3 import QtQuick.Controls 2.2 ColumnLayout { property variant data property alias clData: clData Text { text: qsTr("Public Data") anchors.fill: parent verticalAlignment: Text.AlignVCenter horizontalAlignment: Text.AlignHCenter font.pixelSize: 32 font.bold: true } Flickable { id: flickable Layout.fillHeight: true Layout.fillWidth: true clip: true contentHeight: clData.height ColumnLayout { id: clData property int leftWidth: parent.width * 0.25 anchors.right: parent.right anchors.rightMargin: 0 anchors.left: parent.left anchors.leftMargin: 0 anchors.top: parent.top anchors.topMargin: 0 StartupPublicDataRow { title: qsTr("Project Start") value: "today" lhsplit: 25 anchors.fill: parent } } } }
and the referenced StartupPublicDataRow.qml is like this:
import QtQuick 2.7 import QtQuick.Layouts 1.3 RowLayout { property string title: 'Title' property string value: 'Value' property double lhsplit: 25 Layout.fillWidth: true Text { text: title font.bold: true font.pointSize: 10 wrapMode: Text.WordWrap Layout.maximumWidth: parent.width * lhsplit / 100 } Text { text: value Layout.fillWidth: true font.pointSize: 10 wrapMode: Text.WordWrap } }

@peteispo: Please file a bug report on bugreports.qt.io
Even if you had done something wrong, QtCreator should not crash.

@aha_1980 I thought so too, but I wanted to check that it wasn't an obvious mistake...
