Why does the statement:
ArrayList<ProjectBean> projectList = (ArrayList<ProjectBean>)(session.getAttribute("currentProjectList"));
generate the following warning message:
"Type safety: Unchecked cast from Object to ArrayList<ProjectBean>"

The code runs correctly.
I have imported ProjectBean.
I am not sure why I am getting the warning. Confused

This is really more of a Java question, isn't it Andy?

Good forums for Java questions include JavaRanch and JGuru.
