I don't see the "Sticky: API Documentation Content Bugs" thread which is present in "Ext 4: Bugs", so I'll report this as a regular bug.

The childmove event has a new name in 5.1, but the prevIndex and newIndex parameters are still described as components, but these are numbers.



Code:



Ext.define('Ext.container.Container', {
    ...
    /**
     * @event childmove
     * Fires after any {@link Ext.Component} has changed its ordinal position within the container.
     * @param {Ext.container.Container} this
     * @param {Ext.Component} component The component that was moved
     * @param {Ext.Component} prevIndex The previous ordinal position of the Component
     * @param {Ext.Component} newIndex The new ordinal position of the Component
     */
     ...
