Getting all values in save method and getting exception as System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out

Possible Suggestion/Solution #1

sendEmail is declared as a void return method - i.e. returns nothing.

Morever its a @future call, so it isnt in the same execution context, you can't expect a return value from a future method anyways, as it starts a new thread of execution.

If you wish to check what its doing, I'd suggest setting up Debug Logs (Setup > Monitoring > Debug Logs) and trace the flow there.
