Method Detail

attributeAdded

public void attributeAdded(javax.servlet.ServletRequestAttributeEvent servletRequestAttributeEvent)

This method is called after an attribute is added to the ServletRequest. Note that this should only get called for remote WSRP portlets. For more info, see: http://issues.liferay.com/browse/FACES-146

Specified by:

attributeAdded in interface javax.servlet.ServletRequestAttributeListener

attributeRemoved

public void attributeRemoved(javax.servlet.ServletRequestAttributeEvent servletRequestAttributeEvent)

This method is called after an attribute is removed from the ServletRequest. One might expect that this is a good time to call any managed bean methods annotated with @BridgePreDestroy, but that actually takes place in the Bridge's RequestAttributeMap.remove(Object) method. Note that this should only get called for remote WSRP portlets. For more info, see: http://issues.liferay.com/browse/FACES-146

Specified by:

attributeRemoved in interface javax.servlet.ServletRequestAttributeListener

attributeReplaced

public void attributeReplaced(javax.servlet.ServletRequestAttributeEvent servletRequestAttributeEvent)

This method is called after an attribute is replaced in the ServletRequest. One might expect that this is a good time to call any managed bean methods annotated with @BridgePreDestroy, but that actually takes place in the Bridge's RequestAttributeMap.remove(Object) method. Note that this should only get called for remote WSRP portlets. For more info, see: http://issues.liferay.com/browse/FACES-146
