public class ERXWOForm
extends com.webobjects.appserver._private.WOHTMLDynamicElement

Transparent replacement for WOForm. You don't really need to do anything to use it, because it will get used instead of WOForm elements automagically. In addition, it has a few new features:

• it adds the FORM's name to the ERXWOContext's mutableUserInfo as as "formName" key, which makes writing JavaScript elements a bit easier.
• it warns you when you have one FORM embedded inside another and omits the tags for the nested FORM.
• it pushes the enctype into the userInfo, so that ERXWOFileUpload can check if it is set correctly. ERXFileUpload will throw an exception if the enctype is not set.
• it has a "fragmentIdentifier" binding, which appends "#" + the value of the binding to the action. The obvious case comes when you have a form at the bottom of the page and want to jump to the error messages if there are any.
• it adds the secure boolean binding that rewrites the URL to use https.
• it adds the disabled boolean binding allows you to omit the form tag.
• it adds a default submit button at the start of the form, so that your user can simply press return without any javascript gimmicks.
• the id binding can override the name binding.

This subclass is installed when the frameworks loads.

Bindings

Name	Description
action	Action method to invoke when this element is activated.
actionClass	The name of the class in which the method designated in directActionName can be found. Defaults to DirectAction.
addDefaultSubmitButton	Injects a submit button at the beginning of the form since some browsers will submit the form using the first nested button when the return key is pressed. Default is false unless it is set to true in the properties file.
directActionName	The name of the direct action method (minus the "Action" suffix) to invoke when this element is activated. Defaults to default.
disabled	Disabling a form omits the form element's tags from the generated html. ERXWOForm will automatically disable any nested forms and post a warning to the console if this value is not set.
enctype	The encoding type of the form. If a form has a file upload and this is not set to multipart/form-data then an exception is thrown.
fragmentIdentifier	appends "#" + the value of the binding to the action.
href	The HTML href attribute
id	The HTML id attribute
method	The HTTP method used by the form. It can be get or post
multipleSubmit	If multipleSubmit evaluates to true , the form can have more than one submit button, each with its own action. By default, the value is false unless it is set to true in the properties file.
name	The HTML name attribute
queryDictionary	Takes a dictionary of values that will be submitted with the form.
secure	Determines if the form is secured with SSL. Default is false.
embedded	when true, a form inside of a form will still render. this is to support forms inside of ajax modal containers that are structurally nested forms, but appears as independent to the end-user

Properties

Name	Description
er.extensions.ERXWOForm.multipleSubmitDefault	the default value of multipleSubmit for all forms, defaults to false
er.extensions.ERXWOForm.addDefaultSubmitButtonDefault	whether or not a default submit button should be add to the form, defaults to false
er.extensions.ERXWOForm.useIdInsteadOfNameTag	whether or not to use id instead of name in the form element, defaults to false
