Datatable sync with bData.length = 0

Hello,

When I try to sync datatable with dataset (Backbone.Collection) without records webix does not update datatable, line 27758:

if (bData.length){
	datareset(wData, bData);
}

And I see in Datatable old data from other dataset. Is it normal?

No it is normal. Fix will be included in next update
For now you can change the above like like next

if (bData.length || wData.count()){
    datareset(wData, bData);
}

Thanks
