FilterDispatcher accepts ".action" in the action name, but the AJAX validation
code doesn't

When we use WW HTML form tag, the correct way to do it is write the action name
without the ".action" extension, which will be added automatically by the JSP
tag in the generated HTML tag:
<#-- Using freemarker --#>
<@ww.form action="myaction" method="post" validate="true" theme="ajax">
However, if you do write the ".action" extension:
<@ww.form action="myaction.action" method="post" validate="true" theme="ajax">
The FilterDispatcher works anyway, dispatching the request to the correct
action. However, the validation framework generates a JavaScript code WITH the
".action" extension:
var containingForm = document.getElementById("myaction.action");
Which doesn't work, since it's server counterpart is listening only for calls
to "myaction", with no extension.
This is not a bug, but I think technologies (programming languages, frameworks,
etc.) should strive to maintain orthogonality: if something works in a certain
manner in one part, the user expects it to work in the same manner in all other
parts.
This can confuse begginners, since when you write a HTML form (without JSP
tags), you have to put the .action extension. Some people are used to it and
they keep using it since the FilterDispatcher doesn't mind, but when the
validation doesn't work, the last thing they suspect on is the action property
of the ww:form tag.
This is just a suggestion. I leave the decision to the development team. Thanks!
