Description
Hi,
I want to report a crash issue for ListModel with dynamicRoles enabled. The following code has demonstrated the problem. All the test is passed, but the program crashes on termination. It has been tested on Mac (5.2.1) and Linux (5.3.0 RC. Released on 2rd May). Both of the platform show the same problem.
The purpose of this code is just to show different way to call the method of item in ListModel. Although it is not production code , I think Qt should not crashes by pure Javascript code.
The program will not crash if you turn off the dynamicRoles property . The result will be all green.
Thank you.
import QtQuick 2.0
import QtTest 1.0
TestCase {
name : "QML"
Item {
id : testItem
property string name : "testObject"
property var object : this
function testMethod() {
return -1;
}
}
ListModel {
id : listModel
dynamicRoles : true
}
function test_ListModel() {
listModel.append(testItem);
compare(listModel.count , 1);
var data = listModel.get(0);
compare(data !== testItem, true);
compare(data.name , "testObject");
compare(typeof data.testMethod !== "function",
true);
compare(typeof data.object.testMethod , "function");
compare(data.object.testMethod() , -1);
listModel.clear();
listModel.append({ item : testItem });
data = listModel.get(0);
compare(data.item === testItem, true);
compare(data.item.name , "testObject");
compare(typeof data.item.testMethod , "function");
}
}
