ZK8 - how is FormDirty determined

We have just upgraded to ZK8.

We have a lot of forms as follows:

<fromcomponent form="@id('formData') @load(vm.dataModel) @save(vm.dataModel, before='doSaveDataModel')"  formDataModified="@load(formDataStatus.dirty)">

    ........

The formComponent setFormDataModified method makes the submit button visible if dirty is true.

In ZK8 I notice if I change a text field on the form then the formDataStatus.dirty returns true and the submit button is displayed. However if I change the text field value back to the previous value then the formDataStatus.dirty still returns true.

This behaviour wis different to ZK7 where the formDataStatus.dirty would return false if the text field value was changed back to the original.

Is there anything else I need to implement to make it work the way it used to in ZK7 ?
