Return:

Object

hasDirtyData

public boolean hasDirtyData(AdfUIComponent=|Node ancestor)

Check if the component is dirty or if there are dirty components or form elements below a given component.

Parameters:

ancestor

-

optional client component or DOM node to use to check below. If not given the function checks the entire page, otherwise it will check if any form elements or client components are dirty that are descendents of the given component.

Return:

boolean - true if the component is dirty or any descendent of the component.

Init

protected Object Init(Object page)

Initializes the instance. Subclasses of AdfObject must call their superclass' Init

Parameters:

Object

Overrides:

AdfObject.Init()

InitClass

protected static Object InitClass()

Return:

Object

_initPotentiallyDirtyFlags

Return:

Object

isDirty

public boolean isDirty(AdfUIEditableValue|string inputComponent)

Check if a client component has data that has not been updated on the server.

Parameters:

inputComponent

-

the input component to check if it contains dirty data. The client ID of a component is also an accepted argument.

Return:

boolean - true if the input component has dirty data

_isImmediateEditableValueComponent

Parameters:

clientId

Return:

Object

_isInputComponentElement

private boolean _isInputComponentElement(AdfUICoponent component,
                                         Element formElement)

Check if a form element belongs to an input component element.

Parameters:

component	-	the closest ancestor component
formElement	-	the node to check

                            Object inputElement)

Parameters:

page
component
inputElement

Return:

Object

isNamingContainerDirty

public Object isNamingContainerDirty(string clientId)

Performs an optimized search compared to hasDirtyData to search for dirty data underneath a naming container component using its client ID.

Parameters:

clientId

-

the client ID of the naming container component

Return:

Object

Return:

Object

_needsSpuriousDirtyValueTracking

private Object _needsSpuriousDirtyValueTracking(Object page)

Tests whether the dirty state service should enable "spurious" dirty value tracking. Normally, the dirty state service relies on DOM events (eg. focus, blur) and ADF component events (eg. AdfValueChangeEvents) to determine whether an input component is dirty. This event-driven approach assumes that these events will actually be delivered when the user modifies each editable value. Unfortunately, this assumption does not hold up when running under Selenium RC. Selenium RC has a bad habit of dropping DOM events (eg. focus, blur, change). This can lead to a failure to deliver AdfValueChangeEvents as well as a failure to detect dirtied components. When dirty postbacks are enabled, these missing events can lead to a the omission of dirty values from the postback payload, which can easily result in test failures. To help work around these Selenium RC-specific failures, the dirty state service facilitates another mechanism for detecting dirty values. Rather than rely entirely on proper DOM/component event delivery, the dirty state service can also ask the peer whether it considers itself to be dirty. This check is done by calling __isSpuriousDirtyValue() on the peer. In some cases, peer implementations of __isSpuriousDirtyValue() may require access to some stored state (eg. the peer's initial value). In order to allow for clean up of this state, the dirty state service also calls __resetSpuriousDirtyValue() on the peer to let it know that a previously reported "spurious" dirty value has been processed by the server. Since this spurious dirty value tracking mecahnism does add some overhead, rather than always enabling this feature, it is only enabled when we detect that a) dirty postbacks are enabled and b) we are running inside of Selenium RC.

Parameters:

page

Return:

Object

__registerDirtyDataComponent

Object __registerDirtyDataComponent(Object component,
                                     Object level)

Parameters:

component
level

Return:

Object

AdfDhtmlPage.registerDirtyDataComponent(AdfUIComponent, Object)

_resetSpuriousDirtyValue

private Object _resetSpuriousDirtyValue(Object clientId)

Resets a single spurious dirty value. Note that unlike _resetSpuriousDirtyValues(), this method assumes that the caller has already verified that _needsSpuriousDirtyValueTracking() is true.

Parameters:

clientId

Return:

Object

_resetSpuriousDirtyValues

private Object _resetSpuriousDirtyValues(Object page,
                                         Object dirtyComponentIds)

Resets spurious dirty values for all components specified in the dirtyComponentIds collection, if _needsSpuriousDirtyValueTracking() is true.

Parameters:

page
dirtyComponentIds

Return:

Object

__resetState

Object __resetState()

Clears all the data for tracking dirty state. Resets everything to be "clean".

Return:

Object

setDirty

public Object setDirty(string clientId,
                       boolean dirty)

Marks the specified client id as dirty for the purposes of uncomitted data warning and dirty postback payload tracking. Note that we are temporarily exposing this package-private method for one reason only - to work around a Selenium bug where Selenium:

1. Fails to deliver a blur event. And...
2. Instead delivers a bonus focus event.

When this happens, AdfDhtmlInputBasePeer's last value tracking is hosed, and we lose track of the fact that the input value has been modified. For the moment, we work around this by allowing AdfDhtmlInputBasePeer to notify us when it detects this scenario.

Parameters:

clientId	-	the ID of the client component to be marked as dirty.
dirty	-	if true, will mark the component as dirty, false to mark the component as not being dirty

Return:

Object
