Not able to reset arraydataprovider variable

Content

I have a table  with data populating from arraydataprovider.  

I have dragged and dropped a select-one element in one of the column and set the value for the select-one as

arraydataproviedername.[$currrent.index].adpcolumnname 

Once I select the value from the options and click save button the value gets updated  in the adp without hinderance(save process: for each of adp->call update restendpoint)

But I am not able to use the reset for the adp variable. It throws an error as cannot read adpcolumnname
