setUserData takes two parameters: a key and a value. It's used ONLY by your
code, which can later retrieve the value with getUserData(key). So in your
function that tries to save the data at the server but the server says,
"sorry, can't do it" you could call
this.table.setUserData("currentCellEditing", event.value);
this.table.startEditing();
The act of calling startEditing() causes the cell editor factory to be
invoked. Look at qx.ui.table.celleditor.TextField as a simple one to extend.
Your cell editor factory can then call:
var valueToEdit = table.getUserData("currentCellEditing") ||
cellEditor.originalValue;
table.setUserData("currentCellEditing", null);
In other words, if there's user data available from a failed save attempt,
it'll put that into the cell editor; otherwise the value from the data
model.
