Connection between two tabs for AEM forms

[PranavJoshi]

If I am opening my form in two tabs and changing/saving data in one tab, how can I make it reflect in another one.

Maybe by refreshing/without refreshing the page OR something like Broadcast Channel API.

If you have done the data binding in the fields, then using the somExpression of the fields you can set data of any field across the form.
