StrutsApi

One lesson I've learned is that, in the struts-config.xml, make sure that the form name and the attribute name for that form are the same. Otherwise things can get messed up and multiple instances of the form will get created if you use the incorrect case somewhere. It'll happen without any visible errors, but it'll result in form fields being set or not set in strange ways.

Error handling:

• A good alternative to using html:errors. Use logic:messagesPresent.
