Type is instantiated recursively

This warning category is spelled [type-instantiated-recursively] by qmllint.

Type can't be instantiated recursively

What happened?

A component instantiated itself.

Why is this bad?

The component needs itself to instantiate itself, creating an infinite loop. The QML runtime will error out on this component.

Example

// MyComponent.qml
import QtQuick

Item {
    MyComponent {}
}

To fix this warning,

• Replace the problematic component with another one if it was a mistake.
• Postpone the instantiation to later, with Dynamic QML Object Creation from JavaScript for example.

// MyComponent.qml
import QtQuick

Item {
    // solution 1: MyComponent was not needed here, use another type
    Item {}

    // solution 2: add a MyComponent property and set it later
    property MyComponent myChild
}
