Re: Design Decision RPC with AsyncDataProvider

You can set a string identifier to your columns by using Column.setDataStoreName(). The easiest identifier would be the raw database column name. Then you can go through the ColumnSortList of your CellTable, read the database column name and sort order of each sorted column and pass this information to the server. This information can then be used to build your ORDER BY clause.

Then you only need to detect if sort order has been changed so you can switch back to page one in your CellTable. To do so you can add a ColumnSortHandler to each column, which gets notified as soon as sort order changes.
