Erro com canceledit ao inserir novo item

[KLEBER]

Hi.
I am implementing a DataForm, and insert a new item, when you cancel displays the following error.
"CancelEdit is not allowed during a transaction begun by addnew"

This is my code.

Hi,

 May you please let me know how do you cancel the insert? Do you cancel it when the "dtForm_EditEnded" event is raised?

Hi.
I do not call the event manually, i just click on insert button from dataform without add information, then when click on cancel button, get error.

Hi,

 I have tried to get such an error on cancelling the insert, but I was not able to. How do you submit the changes for the DomainDataSource? Do you get the same behaviour if you use the RadDomainDataSource?
