java.lang.Object
- org.apache.tapestry5.corelib.internal.FormSupportAdapter

All Implemented Interfaces:

ClientElement, FormSupport
```
public class FormSupportAdapter
extends Object
implements FormSupport
```
An implementation of FormSupport that delegates all behavior to another instance of FormSupport. This allows some of the behavior to be overridden easily.

Methods
Modifier and Type	Method and Description
`void`	`addValidation(Field field, String validationName, String message, Object constraint)` Collects field validation information.
`String`	`allocateControlName(String id)` Allocates a unique (within the form) control name for some enclosed component, based on the component's id.
`void`	`defer(Runnable command)` Defers a command until the end of the form submission.
`String`	`getClientId()` Returns a unique id for the element.
`String`	`getFormComponentId()` Returns the complete id of the underlying Form component.
`String`	`getFormValidationId()` Id used as a prefix when searching `Messages` for validation messages and constraints.
`boolean`	`isClientValidationEnabled()` Return true if client validation is enabled for this form, false otherwise.
`void`	`setEncodingType(String encodingType)` Sets the encoding type for the Form.
`<T> void`	`store(T component, ComponentAction<T> action)` Stores an action for execution during a later request.
`<T> void`	`storeAndExecute(T component, ComponentAction<T> action)` As with `FormSupport.store(Object, org.apache.tapestry5.ComponentAction)`}, but the action is also invoked immediately.
`<T> void`	`storeCancel(T component, ComponentAction<T> action)` Stores an action for execution in a later request when the containing form is canceled.

public FormSupportAdapter(FormSupport delegate)
```
- Method Detail
  - allocateControlName
```
public String allocateControlName(String id)
```
    Description copied from interface: FormSupport
    
    Allocates a unique (within the form) control name for some enclosed component, based on the component's id.
    
    Specified by:
    
    allocateControlName in interface FormSupport
    
    Parameters:
    id - the component's id
    
    Returns:
    a unique string, usually the component's id, but sometime extended with a unique number or string
  - store
```
public <T> void store(T component,
             ComponentAction<T> action)
```
    Description copied from interface: FormSupport
    
    Stores an action for execution during a later request. If the action contains any mutable state, it should be in its final state before invoking this method and its internal state should not be changed subsequently.
    
    Specified by:
    
    store in interface FormSupport
  - storeAndExecute
```
public <T> void storeAndExecute(T component,
                       ComponentAction<T> action)
```
    Description copied from interface: FormSupport
    
    As with FormSupport.store(Object, org.apache.tapestry5.ComponentAction)}, but the action is also invoked immediately. This is useful for defining an action that should occur symmetrically in both the render request and the form submission's action request.
    
    Specified by:
    
    storeAndExecute in interface FormSupport
    
    Parameters:
    component - component against which to trigger the action
    action - the action that will be triggered (and passed the component)
  - defer
```
public void defer(Runnable command)
```
    Description copied from interface: FormSupport
    
    Defers a command until the end of the form submission. The command will be executed before the Form's validate notification, but after all other submit actions for the form have been processed. This is used, primarily, to coordinate validations or other operations that involve multiple components, when the order of the components can not be determined. During a form render, runnables are executed after the body of the form has rendered.
    
    Specified by:
    
    defer in interface FormSupport
    
    Parameters:
    command - to be executed
  - setEncodingType
```
public void setEncodingType(String encodingType)
```
    Description copied from interface: FormSupport
    
    Sets the encoding type for the Form. This should only be set once, and if
    
    Specified by:
    
    setEncodingType in interface FormSupport
    
    Parameters:
    encodingType - MIME type indicating type of encoding for the form
  - addValidation
```
public void addValidation(Field field,
                 String validationName,
                 String message,
                 Object constraint)
```
    Description copied from interface: FormSupport
    
    Collects field validation information. A Form may turn off client-side validation, in which case these calls will be ignored.
    
    Specified by:
    
    addValidation in interface FormSupport
    
    Parameters:
    field - for which validation is being generated
    validationName - name of validation method (see Tapestry.Validation in tapestry.js)
    message - the error message to display if the field is invalid
    constraint - additional constraint value, or null for validations that don't require a constraint
  - getClientId
```
public String getClientId()
```
    Description copied from interface: ClientElement
    
    Returns a unique id for the element. This value will be unique for any given rendering of a page. This value is intended for use as the id attribute of the client-side element, and will be used with any DHTML/Ajax related JavaScript.
    
    Specified by:
    
    getClientId in interface ClientElement
  - isClientValidationEnabled
```
public boolean isClientValidationEnabled()
```
    Description copied from interface: FormSupport
    
    Return true if client validation is enabled for this form, false otherwise.
    
    Specified by:
    
    isClientValidationEnabled in interface FormSupport
  - getFormComponentId
```
public String getFormComponentId()
```
    Description copied from interface: FormSupport
    
    Returns the complete id of the underlying Form component.
    
    Specified by:
    
    getFormComponentId in interface FormSupport
  - getFormValidationId
```
public String getFormValidationId()
```
    Description copied from interface: FormSupport
    
    Id used as a prefix when searching Messages for validation messages and constraints. This is normally the simple id of the form.
    
    Specified by:
    
    getFormValidationId in interface FormSupport
    
    Returns:
    validation id string

  - storeCancel
```
public <T> void storeCancel(T component,
                   ComponentAction<T> action)
```
    Description copied from interface: FormSupport
    
    Stores an action for execution in a later request when the containing form is canceled. Cancel actions are triggered before the form fires its EventConstants.CANCELED event.
    
    Specified by:
    
    storeCancel in interface FormSupport
