Does this method updates a ListDataProvider ?

Hi,

I have multiple ListDataProviders which i store them in a table to access them later. The problem is what is the efficient way to access and update each ListDataProvider in order to see the changes? Here is what i do:

// 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();

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

Is this a good way to do it? Thanks.
