How to identify if any values in screen is changed by user

[Rajin Das]

Hi,

I want to alert the user to save the form, if he has changed any
value
in the form and not saved that, in this case when the user leave the
page with out saving i want to show him an alert message asking him
to
save the data.

it can be done with the help of onUnload method, but how we can
identify if the user has changed any value in the screen or not,
please is any one have found a solution for this or got any idea it
will be of great help

thanks in advance

This can done through Editor Framework.

Activities and Places has a method to do this in the presenter too. Link the presenter up with the Editors.
