    How to set a Field Error without reverting user's change

    Hi all,
    I'm trying to set an error to a specific field when that field is > than another field in that row. However, for some reason it reverts the value chosen to the older one.
    For example:
    I have a field myFirstFieldItem with choices of 2, 4, 6 for the user and another field myOtherItem with choices of 2, 4, 6 for the user
    If teh user chooses 6 for myFirstFieldItem and 2 for myOtherItem I want an error on myFirstFieldItem to show. I don't, however, want it to revert the change.

    Here is my code:

    myFirstFieldItem .addChangedHandler(new {
    public void onChanged( event) {

    int row = event.getRowNum();
    Record record = myGrid.getRecord(row);

    int myFirstFieldItemIdx =event.getValue();

    int myOtherItemValIdx= record.getAttribute("myOtherItem");

    if (myFirstFieldItemIdx > myOtherItemValIdx) {
    String message = "myFirstFieldItem is greater than myOtherItemValIdx";
    myGrid.setFieldError(row, "myFirstFieldItem ", message);
    } else {
    myGrid.clearFieldError(row, "myFirstFieldItem ");

    I also tried it with .addChangeHandler but still got the same thing.

    Hi deedee,

    did you already see FormItem.setValidators() and perhaps setValidateOnExit()? This is the more declarative solution to your problem. I don't know about the "change back", though.

    Best regards
