+\title Duplicated Name
+\brief Multiple signals or properties share the same name in the same Component.
+
+This warning category has multiple warnings:
+\list
+    \li \l{Duplicated Property Name}
+    \li \l{Duplicated Signal Name}
+\endlist
+
+\section1 Duplicated Property Name
+
+\section2 What happened?
+Multiple properties in the same QML component scope have the same name.
+
+\section2 Why is this bad?
+Components with duplicate property names will not be created at runtime: they will be null instead.
+
+\section2 Example
+\qml
+import QtQuick
+
+Item {
+    property int helloWorld
+    property int helloWorld
+}
+\endqml
+You can fix this warning by removing the duplicate property or renaming it:
+\qml
+import QtQuick
+
+Item {
+    property int helloWorld
+}
+\endqml
+
+\section1 Duplicated Signal Name
+
+\section2 What happened?

+
+\section2 Why is this bad?

+\qml
+import QtQuick

+Rectangle {

+    signal helloWorld
+}
+\endqml

+\qml
+import QtQuick

+Rectangle {
