Table Of Contents Component Leaks

If 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.
