I solved how to set cell editor readOlny = false, now i get another problem.
What i need to do is:
I have a column Id which is not editable on load data, but it is editable when i add a new row. So i need to set the cell id editable only when i add a new row.
the problem with this code is that all the rows are with column id editable.
newRecord = store.insert(0, newRecord);
So this is my problem...
