Hi @kiruba04 ,  
No there is no way to get rid of the index shift. Removing that would also lead to other problems such as empty/null objects in the place where an element was deleted.

The default renderer does not add any unique ids to array elements. However, you could just implement a custom renderer that generates a unique id for each created array element.

Best regards,
