Sometimes, there are elements used on an input form that the application does not need to capture. For example, buttons create input values, but you might be attaching Actions to the buttons, rather than utilizing the button press as input.

When devMode is on, the framework reports when there is an attribute in the request that is not being havested by an Action property. (In case you just forgot to create the property.)

• To eliminate the warning message, edit or create the struts.properties file and set devMode to false (off).
