RE: [Q] Accessing struts-tiles attribute in a bean?
Ted (Husted) has created a 'tiles for Velocity'.

(Great minds and all that.) You defined a second file to administer the template. This works well enough but it tends to generate a lot of meta-templates that are just used to call other templates.

Instead of forwarding to the glockenspiel.vm template, you can foward to make a reference to say /vm/Glockenspiel and Struts will automatically look for a vmGlockenspiel element, do whatever sets you need, and the forward to the layout. A very neat aspect of Tiles, that we need to adopt for the other Struts configurations, is that one element can extend another. So if you just needed to replace the title on a page, you can extend one element and just override that one set. This makes a *huge* difference in maintenance when you pass the thirty page mark. Until one of us gets around to writing a Tiles tool, I've prototyped what you can do in the Struts config. I've a ViewAction that does the setting. You create the variables to set as Struts ActionForwards and pass their names to ViewAction as ActionMapping parameter. So I have something like this to describe a page: action path=/vm/main/permit/View type=us_ok_deq_wqdata.http.ViewAction validate=false name=permit_select_id parameter=vmTitle,vmChoice,vmMenu,vmBody,vmAction,vmButtonBar forward name=vmTitle path=Permit Detail / forward name=vmChoice path=View / forward name=vmMenu path=/cpu/menu/main.vm / forward name=vmBody path=/cpu/permit/view.vm / forward name=vmAction redirect=false path=/Main / forward name=vmButtonBar path=/cpu/permit/viewMain.vm / /action To render the same page but with a different button bar, I'd just change that forward to include some other template instead. Besides URI's for parse statements, you can also pass any variable you need to create. For example, vmChoice tells the menu which item we are on, so it can dim that one (and leave the rest linked). While we can't extend struts-config elements (yet), the ActionForwards do have a local and global scope. So you can do things like create a global default forward and let that pass through when it doesn't need to be changed. This is done for the Layout. There's a default vmLayout forward which can be overridden by an element if you need to use a different layout. This works fine inside of Struts and will work even better when we get the Struts config to support extended elements like the Tiles config. But, it seems to me that it's something that could also be done outside of Struts and made available to anyone using Velocity. For programmers, this sort of thing makes the templates feel object-orientated. You can define a base element and then extend it to say what changes. For designers, they can use Velocity templates seem more like fill-in-the-blank Dreamweaver templates. A GUI, like Struts Console, can even save you from mucking about with XML. -Ted. = For more see, http://www.mail-archive.com/[EMAIL PROTECTED]/msg09304.html There's a copy of my ViewAction at http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/wqdata/src/java/shared/org_apache_struts_scaffold/ViewAction.java -- Ted Husted, Struts in Action http://husted.com/struts/book.html - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: [Q] Accessing struts-tiles attribute in a bean?
Great links, Thanks Ted. I suppose the ultimate objective (imho) would be to extend tiles so it could utilise other views rather than just jsp. This could then leverage the great work Cedric has done on tiles wrt XML definitions and 'extends' definitions. Sorry if this seems like a really dumb/lazy q but how does the .vm get passed to velocity for processing - is this just via a servlet-mapping in web.xml. If so, could tiles not be extended to also pass the appropriate extension to a servlet mapping for processing? (Has anyone run any ideas past Cedric?). I'm not advocating even stronger dependence between the components - as I know you have strong and I think perfectly justifiable views on this - but tiles allowing a different processing engine for a resource could be very powerful. Ok, it could be tiles already does this - and I'm just rambling. I'll have a look again at the tiles code and try some examples before posting again.

Re: [Q] Accessing struts-tiles attribute in a bean?
Not sure of 'best' way to this but I think this may work:
tiles:useAttribute name=booboo classname=java.lang.String /
...
bean:message key=%=booboo% /
...or with bean-el you can do
bean:message key=${booboo}/
I do this as well as tiles does not support localization just yet.
However, it looks like it will be implemented in the future as there
are several bugzilla reports on it. Conception would of course be
to set key attribute in tiles.
