Qt 5.3 QML Application crashes with associative array

are you sure that worked before? I could never get it to work to assign objects to properties directly. I thought that is a feature of QML and the {} are parsed as a function like you do with slots (onClicked: {} is a slot and not an JS object as far as I know). So with Qt 5.2 and 5.2.1 it is a QMl syntax error to do something like property var foo: {} or do you have to use variant in that case? I thought you should always use “var” instead of variant in newer version of Qt? anyway my solution is to use a helper function that always works: property var foo: getFoo() function getFoo() {   return { ... } }
