Dear Support,

I have some forms that is bind to MVVM and I am binding the VM's change event to check for any pending changes on the form.  The issue I am having is for textarea that is bind to null value, if I tab/click on the textarea and leave without making any changes, it will still trigger the VM's change event.

What is the solution for this?
