Dear Wiki user, You have subscribed to a wiki page or wiki category on "Struts Wiki" for change notification.
The following page has been changed by MichaelJouravlev: http://wiki.apache.org/struts/StrutsManualActionWebComponentSync ------------------------------------------------------------------------------ In Struts 1.2.9 - 1.3.x Action class does not implement dispatching functionality, you need to extend a dispatching action. Use !EventDispatchAction as the simplest and the most flexible choice. Another difference is that you need to specify an {{{ActionForward}}} object that points to a component view. You must do it in {{{unspecified}}} method or whatever method you selected as default in event definition. - Using !EventDispatchAction to handle incoming events gets you only halfway, because the code that automatically distinguishes the address of a composite page and then redirects to it is not present in older Struts versions. You need an add-on library that contains this code. Then you need to call it from {{{execute}}} method of your action.
