I am trying to write a GMAIL contextual gadget. I am ready with all the building blocks (services , gadgets, manifest.repositories...) basic hello world is working fine.
To simplify lets say, " I have a Mark as favorite " functionality in my widget
I would be needing to store (in my SQL database) some object against some marked as favorite mails.
And as the mails would open, my widget would load and now i want to make an ajax call to my database and check if "this particular mail" is a favorite mail or not.
ques : I just require a Unique message id in my java-script so that whenever any user marks an email as favorite. I would store that unique message id in the favorite list in my database.
