Grid inside tab panel not working properly

[Celso67]

I am using GPL ExtJS 6.2.0.981

I hava a grid inside a tab panel (plese see picture). When I click to add row, the grid add rows in the same position 0.

The modelo is correct, because when i put the grid in a form works fine..

I have found it:

Wrong:

var rec = new Orbe.model.sistema.pagar.PagarConta({
codigo: 0
, conta: ''
, valor: ''
, percentual: ''
});

Correct

var rec = new Orbe.model.sistema.pagar.PagarConta({
codigo: ''
, conta: ''
, valor: ''
, percentual: ''
});
