\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
