Stop new item from inserting

[RPHAELLA]

For insertItem(item): Promise|insertedItem,
If no item is returned, inserting item will be used as inserted item.

In my case, validation is added to insertItem(item) function, thus, if the validation fail, no ajax was send to insert data into the database. Yet, new row is still added to the table without fail, how do i disable the new insertion?

Please, check out this ticket #54
For the insert you should redefine finishInsertmethod.

The build-in ability is planned, it will be possible to do with onItemDeleting callback.
