Does this method update a ListDataProvider ?

I have multiple ListDataProviders, in which I store in a table to access them later. The problem is finding what is the efficient way to access and update each ListDataProvider and update it in order to see the changes? Here is what I am currently doing:

// a Guava table to store the data providers  // i get the data provider by Row and Column  Table<Row, Column, ListDataProvider> REGISTER = createTable();    // I create a copy of the data provider that i want to update  ListDataProvider<T> prevDataProvider = getDataProvider(Row,Column);  ListDataProvider<T> newDataProvider = getDataProvider(ROW_1, Colummn_1);    // I make changes on the copies  newDataProvider.getList().remove(e_1);  prevDataProvider.getList().add(e_1);    // Then i refresh the copies  newDataProvider.refresh();  prevDataProvider.refresh();

I can see the changes, but sometimes the element is added to the new data provider but still exists in the previous one, so it not remove or the previous data provider didn't have a chance to remove the element.

Is this a good way to do it? Thanks.
