How to insert record in the end of the grid

Hello everyone!
I want to share with you some useful information.
I need to insert new records in the end of the grid. The DAX standatd behaviour's don't let this.
So I have found solution, how to do this.
Here's code, you just need to override create method on needed datasource:

public void create(boolean _append = true)
{
    this.last();
    super(_append);
}

The mose important in this code -  _append property.
By default it has false value, but we need to change it on "true"  otherwise our code won't work.

Please, if you have any questions - comment or send me e-mail!
Thanks!
