DHTMLX Grid in suite 7.0

I have found a problem with initialize grid using suite 7.
If I initialize a normal grid, for example:

<div id="grid"></div>

<script type="text/javascript">
     var grid = new dhx.Grid("grid");

return this error:
dhtmlx Uncaught TypeError: Cannot read property ‘autoEmptyRow’ of undefined

So I have set autoEmptyRow:false in object configuration properties and now works great… but it is normal setting this parameter when I would initialize empty grid, before attach columns and dataset?

Unfortunately it is not avialable to initialize the grid without the columns.
columns property is a mandatory for the initiali grid configuration.
