Re: TilesAction and Controller

[Cedric Dumoulin]

Hi,

If you don't need the struts properties, use a Controller class and controllerClass.
If you need the struts preprocessing or the struts properties in your controller, use a TilesAction and controllerUrl.
A TilesAction is a regular Struts action which can be called through the servlet mechanism, and so can be catch and preprocessed by Struts. In addition, a TilesAction should be declare in the struts config file, and called throw its URL.

For Struts 1.1b3 and the soon to be released Struts 1.1 RC1, do you
recommend using TilesAction over the Controller interface
(http://tinyurl.com/62px) for tiles-specific controllers? I just wrote
about using the Controller interface for a Wrox Chapter last night, and I'd
hate to be out of date ;-)

Thanks,

Matt

I found the following in tilesAdvancedFeatures:

If you use a class name as controller, it should extend one of the

following

base classes or interfaces:
org.apache.struts.action.Action (wrapper
org.apache.struts.action.StrutsActionControllerWrapper is

used) If you

provide a Struts Action subclass, it will be wrapped with

the appropriate

class, and
Struts' perform method will be called, but the "mapping" and "form"
attributes will be null.

Does this means that to pass the error via mapping I must use

controlerUrl

in <tiles:insert> tag ? Where is
org.apache.struts.action.StrutsActionControllerWrapper? I

cannot find it
in

src of struts 1.1-b3.

It appears that StrutsActionControllerWrapper is now called
ActionController.

If you use a Struts action as Tiles controller CLASS, the struts
parameters aren't initialized, so you can't use it. I think

you can't

pass error via mapping in this way.
But, if you use a struts action URL as controller, the action is
called throw the struts mechanism, and properly initialized. You can
extends the o.a.s.tiles.actions.TilesAction class and

overload execute(

ComponentContext ...) to get the context.

Question: Just check to make sure that the controllerClass (NOT
controllerUrl) used in <tiles:insert> tag can extends

TilesAction (and
NOT

implements Controller)?

Using TilesAction as a controller, I can pass the

generated error to
the

input page via standard Struts process:
if (!errors.empty()) {
saveErrors(request, errors);
return (new ActionForward(mapping.getInput();
}

Question: How can I achieve the same thing with Tiles Controller?

(assuming

that I can have currentURL and RequestURL as Tiles

attributes in the

request

scope).

Cedric and/or someone may save me time to navigate from

ServletContext

passed into the Controller perform(...) method.

Thanks
