Studio Developer Manual / Version 2101
Table Of ContentsIf a component is destroyed, it is removed from the Ext component manager registry. If the component is a container, all its items are removed as well. But there are cases when components fail to be destroyed:
If two items of the same container use the same itemId, Ext does not complain, but one of them is kept even if the container is destroyed.
Components that are created manually via ComponentMgr.create() have to be destroyed manually unless they are added to the items of a container.
