Method Detail

initContext

public void initContext(LifecycleContext context)

Description copied from class: Phases

During this phase the listener is able to initialize the LifecycleContext with additional information that will be persisted during the Lifecycle.

Specified by:

initContext in class Phases

prepareModel

public void prepareModel(LifecycleContext context)

Description copied from class: Phases

Give the opportunity for the data model to prepare and initialize.

Specified by:

prepareModel in class Phases

applyInputValues

public void applyInputValues(LifecycleContext context)

Description copied from class: Phases

Builds the list of events with their possible associated action binding from the request parameters.

Specified by:

applyInputValues in class Phases

validateInputValues

public void validateInputValues(LifecycleContext context)

Description copied from class: Phases

Validate input values.

Specified by:

validateInputValues in class Phases

processUpdateModel

public void processUpdateModel(LifecycleContext context)

Description copied from class: Phases

Update the data model with new and validated input values.

Specified by:

processUpdateModel in class Phases

validateModelUpdates

public void validateModelUpdates(LifecycleContext context)

Description copied from class: Phases

Forces model-level validation to occur.

Specified by:

validateModelUpdates in class Phases

processComponentEvents

public void processComponentEvents(LifecycleContext context)

Description copied from class: Phases

Process each event accumulated during the previous phases.

Specified by:

processComponentEvents in class Phases

metadataCommit

public void metadataCommit(LifecycleContext context)

Description copied from class: Phases

Used to commit Runtime changes to the metadata. This phase is always called before prepareRender even in case of navigation.

Specified by:

metadataCommit in class Phases

prepareRender

public void prepareRender(LifecycleContext context)

Description copied from class: Phases

Last phase before rendering a page. This can be used to notify a binding that rendering is about to happen and allow them to optimize data preparation or processing before the rendering begins.

During this phase the model is refreshed.

Specified by:

prepareRender in class Phases
