Tong, You can change the form's submit action using almost any form field type (except hidden) using the onClick or onChange methods.
If you have a submit button button, you can do this: <input type="submit" name="Save" value="save" onClick="this.form.action='/save.do';return true;" /> To save the button name into a hidden parameter such as a hidden field ActionName, you can do this: <input type="hidden" name="ActionName" /> <input type="submit name="Save" value="save" onClick="this.form.ActionName.value='save';return true;" /> <input type="submit name="Delete" value="delete" onClick="this.form.ActionName.value=delete';" /> Or even: <input type="submit name="Save" value="save" onClick="this.form.ActionName.value=this.value;" /> (I might be slightly off on the ActionName.value setting property). If you choose to make the onClick invoke a function (for performing even more steps than that) and the input was a submit button, remember to NOT do a form.submit() within that JS function - it would cause a double submit when invoked from a submit button. If it isn't a submit button but some other type of button, you can probably do a form.submit() if it doesn't do it automatically. As for preventing automatic validation in an Action, Erik was spot on with validate="false" as an attribute and value in your <action .../> mapping. Just invoke the validate method with the appropriate arguments for the Action class you're extending. And finally, on your topic of making one select change another select, the only way I know (and did this once, long ago) was to set a javascript function to be called by the first one's onClick or onChange method. That function can be passed the this.form object, then get to the second pulldown by name or id, delete every select item, then add each new item. Creative use of the iterate tag plus javascript can do it, or you could find good examples if you google - that's how I learned how to do it.
