Yes it is possible but you need some JavaScript
You can create a js include file or put this in your wrapper template
file. The idea is to put a event listener on the onbeforeunload
function. I have tested this in a few more common browsers and it
works.
window.onbeforeunload = warnOfUnsavedChanges;
function warnOfUnsavedChanges(){
//You can add a boolean to be set using externalInterface IF
the form/data is dirty in Flex
return 'You have unsaved changes on this page, which will be
discarded if you leave now. Click Cancel in order to save them
first.';
}
Simple string return from the onbeforeunload method does the trick.
I would also like to get this working from inside Flex to use the
externalInterface to inject the needed JS but I did not have luck yet
with this.
