How to file taxes when married in 2010?

My wife and I got married in 2010. I lived in Illinois the entire time and she moved from Wisconsin to Illinois in May 2010 after we got married. Even though we are filing jointly now, the only income taxable in Wisconsin is her income at the job she worked in Wisconsin, right? When she moved to Illinois with me, she quit her job and got a new job in Illinois. Are we correct to only claim her applicable income for Wisconsin?
