I have created a custom xtype named MaterialSelector and used in one of my ext views.
I need to refer parent views from the initComponent function of my custom xtype.
When I console.log this.xtypesChain from initComponent method it returns following array of xtypes
["component", "box", "container", "fieldset", "MaterialSelector"]
When I try to access parent views by xtype like: this.findParentByType('fieldset') script always returns undefined. Whether I am doing something wrong here?
