public class UIMessage
extends UIComponentBase

This component is responsible for displaying messages for a specific UIComponent, identified by a clientId or component id relative to the closest ancestor NamingContainer. The component obtains the messages from the FacesContext.

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

Constructor Detail

UIMessage

public UIMessage()

Create a new UIMessage instance with default property values.

Method Detail

getFamily

public java.lang.String getFamily()
Description copied from class: UIComponent

Return the identifier of the component family to which this component belongs. This identifier, in conjunction with the value of the rendererType property, may be used to select the appropriate Renderer for this component instance.

Specified by:
getFamily in class UIComponent

getFor

public java.lang.String getFor()

Return the Identifier of the component for which to render error messages. If this component is within the same NamingContainer as the target component, this must be the component identifier. Otherwise, it must be an absolute component identifier (starting with ":"). See the UIComponent#findComponent for more information.


setFor

public void setFor(java.lang.String newFor)

Set the 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

isShowDetail

public boolean isShowDetail()

Return the flag indicating whether the detail property of the associated message(s) should be displayed. Defaults to true.


setShowDetail

public void setShowDetail(boolean showDetail)

Set the flag indicating whether the detail property of the associated message(s) should be displayed.

Parameters:
showDetail - The new flag

isShowSummary

public boolean isShowSummary()

Return the flag indicating whether the summary property of the associated message(s) should be displayed. Defaults to false.


setShowSummary

public void setShowSummary(boolean showSummary)

Set the flag indicating whether the summary property of the associated message(s) should be displayed.

Parameters:
showSummary - The new flag value

isRedisplay

public boolean isRedisplay()
Returns:
true if this UIMessage instance should redisplay FacesMessages that have already been handled, otherwise returns false. By default this method will always return true if setRedisplay(boolean) has not been called.
Since:
2.0

setRedisplay

public void setRedisplay(boolean redisplay)

Set the flag indicating whether the detail property of the associated message(s) should be displayed.

Parameters:
redisplay - flag indicating whether previously handled messages are redisplayed or not
Since:
2.0
