CellEditing - Grid EXTJS4 : row validation

[performancetest]

Hi,

I have a grid using CellEditing plugin, I created a button to add new row. I want to validate that the last row added was populated before adding a new row.

I did this with Extjs3 by using

GridStoreName.getAt(0).data['FIELDNAME'] to get the value of the required field in the grid and make sure it is populated.

How can I do this in EXTJS4 ?

Please help

Perhaps this?


store.first().get('FIELDNAME');
