The Alloy UI form tags have changed for Liferay 6.2, so I have to use new HTML tags for this version. Consequently, there are some styles that need readjustments.
The code for 6.2 is in https://svn.rivetlogic.com/repos/rivets/logicstacks/hrportal/branches/6.2%20CE%20GA%201/liferay-plugins-sdk-6.2.0/portlets/calculator-portlet/
