    Does id exist as a config option for Ext.Component anymore?

    * The reason I ask is that unless I'm blind it doesn't seem to be documented.

    Thanks

    A Component's id is determined during instantiation and it can't be changed afterwards (immutable), hence a setId() method doesn't make sense, and that's why 'id' is a not a general config.

    There's two common ways a Component gets its custom id: either via the given 'id' class property of your custom view, or via the 'id' config property (only) during instantiation, e.g:

    Code:
    new Ext.Button({
   id: 'myButton',
   text: 'Foo'
});
