Description
Renders HTML an input form.
The remote form allows the form to be submitted without the page being refreshed. The results from the form can be inserted into any HTML element on the page.
NOTE:
The order / logic in determining the posting url of the generated HTML form is as follows:-
- If the action attribute is not specified, then the current request will be used to determine the posting url
- If the action is given, Struts will try to obtain an ActionConfig. This will be successfull if the action attribute is a valid action alias defined struts.xml.
- If the action is given and is not an action alias defined in struts.xml, Struts will used the action attribute as if it is the posting url, separting the namespace from it and using UrlHelper to generate the final url.

Validation
There are two flavours Client Side Validation, depening on the theme you are using (xhtml, ajax, etc). If you are using the xhtml theme or css_xhtml theme, pure client side validation will be used. If you are using the ajax theme, a special AJAX-based validation will take place. Read the Client Side Validation docs for more information.
