update checkbox after asking the server


I have a CellTable. One of the columns is build like this 
Column<MyProxy, Boolean> colIsReference =
new Column<MyProxy, Boolean>(new CheckboxCell()) {
public Boolean getValue(MyProxy rdm) {
return Boolean.valueOf(rdm.isReference());
colIsReference.setFieldUpdater(new FieldUpdater<MyProxy, Boolean>() {
public void update(final int index, final MyProxy rmd, Boolean value) {
false, // don't override current reference (opens dialog if there is another reference)
new Runnable() {
// called if canceled
public void run() {
      // --->  Do something that unchecks the checkbox  <---

When the user clicks the checkbox of an entry, the server checks if the value may be changed easily at the moment. If yes, I don't have a problem.
If not (some other things have to be changed too) - I ask the user if he wants to change all necessary stuff. The user can click ok or cancel. If he clicks ok, I have no problem. But if the user cancels I want to uncheck the checkbox again.

Whats the best way to do that? I tried to update the table with setRowData (because in my proxy in rmd the flag is still false!) and I have tried with the updateRowData of the asyncDataProvider that I use.

Is there a way to bind the gui closer to my proxy? Because at the moment run() is called the proxy flag is false but the checkbox is true.

Thanks in advance!!
