Button tap isn't fire an event
I have the project below and it events don't work well. Specially the action onClientesListNovoCliente.
Somebody can help me?
When using an itemId you will need to prefix the component with its xtype.
If you use an id you don't have to do that (but you won't be able to create multiple instances of it).
I'd recommend adding an xtype/alias to Listagem, maybe 'listagem'. Then in your controlQuery change it to 'listagem#clientesList'.
Alternatively you could change 'clientesList' from an itemId to an id and this would begin working.
