Batch-Selection of records in datamanager doesn't work

When I click the checkbox to select all records of a page in the datamanager the checkbox in the dataggrid headline is checked and all records are checked, too. In the background an AjaxCall is started which deselects all records. The checkbox in the headline is still checked.

When clicking on the "Delete selected" button below the datagrid some action is performed in the background but Preside comes up with the error message: `No action was performed because no records were selected`.

None of the selected records are deleted.
So, the only way to delete records is to do it manually records by record
