The renderer for this component is responsible for obtaining the messages from the FacesContext and displaying them to the user.

This component supports the Messages renderer-type.

By default, the rendererType property must be set to "javax.faces.Messages". This value can be changed by calling the setRendererType() method.

Method Detail

getFamily

public String getFamily()
Description copied from class: UIComponent

public String getFor()

Return the client identifier of the component for which this component represents associated message(s) (if any).


setFor

public void setFor(String newFor)

Set the client identifier of the component for which this component represents associated message(s) (if any). This property must be set before the message is displayed.

Parameters:
newFor - The new client id

isGlobalOnly

public boolean isGlobalOnly()

Return the flag indicating whether only global messages (that is, messages with no associated client identifier) should be rendered. Mutually exclusive with the "for" property which takes precedence. Defaults to false.


setGlobalOnly

public void setGlobalOnly(boolean globalOnly)

Set the flag indicating whether only global messages (that is, messages with no associated client identifier) should be rendered.

Parameters:
globalOnly - The new flag value
