    Default Answered: Custom Component only instantiates once

    I have written a new component and it works fine if it is only created once (lazy instantiation).
    But as soon as I create it a second time it won't run the applyItemsContainer.

    What do I have to do to create a component twice and always run the applyItemsContainer?

    Code:
    Ext.define('Ext.mgd.DropDown', {
        extend: 'Ext.Component',
        xtype: 'buttondropdown',
    
    
        config: {
            text: '',
            itemsArray: []
        },
        cachedConfig: {
    
    
            itemsContainer: {
                xtype: 'container',
                cls: 'x-dropdown-container',
                items: []
            }
        },
    
    
        template: [
            {
                reference: 'buttonEl'
            },
            {
                reference: 'dropdownEl',
                children: [
                    {
                        reference: 'itemsEl'
                    }
                ]
            }
        ],
    
    
        initialize: function () {
            var me = this;
            me.dropdownAnimation();
            me.getItemsContainer().setItems(me.getItemsArray());
            me.callParent(arguments);
        },
    
    
        applyItemsContainer: function (config) {
            return Ext.factory(config, Ext.Container, this.getItemsContainer());
        },
    
    
        updateItemsContainer: function (newContainer, oldContainer) {
            if (newContainer) {
                newContainer.add(this.getItemsArray());
                newContainer.renderTo(this.itemsEl);
            } else if (oldContainer) {
                oldContainer.destroy();
            }
        }
    }

  2. Move it to config not cachedConfig as it's then cached
