Can you dynamically select which page template to return?
Not sure if that makes any sense but here goes... For each page in Tapestry, I know that I need to specify a page class, and a corresponding TML templage file for that page. I was wondering if I can have more than one possible TML file for a page... and programatically decide which one to use? Hope makes sense.

Re: Can you dynamically select which page template to return?
The localization happens automatically according to the user's locale (although I suppose you could hijack that override it to suite your purposes). However, in trunk (5.3.0/5.3.1-SNAPSHOT), the concept is currently being generalized to support skinning, etc. Robert On Jun 20, 2011, at 6/204:32 AM , dkeenan wrote: Ah.

Re: Can you dynamically select which page template to return?
Thanks Lewis. I can see what you mean. It does sound like I'm trying to do something action-oriented/Struts-like. I'm a big fan of the way Tapestry doesn't force you to think in this way and is more intuitive. The reason I ask actually, is more to do with wanting to re-skin pages based on a user. Ie. want the same content (so just need one page class), but Id like to use a different TML file altogether based on the user. This way, I am hoping to work on 2 separate TML files in design mode, and the can be served based on which type of user is logged in. For example... a funky design versus a more mature design based on the age of the user. Sounds weird :-), but just wondering if there's an easy way to select the TML file at run time, that Tapestry uses with a single page class. I think the localization functionality would actually do just the trick if I just assign the funky styled tml file to one (eg. HomePage_fr.tml) and the refined one (HomePage_en.tml). Then I can programatically set the local based on the logged in user. Does that sound like a completely deranged way of going about it? :-) Thanks, Dave.

I guess most of what you want to do is implementable using CSS alone and a single template. Check csszengarden.com for that.

Re: Can you dynamically select which page template to return?
Thanks Thiago. Yeah I see what you mean also. Ideally the HTML should be the content, and be completely separate from styling (that's CSS's job). This is exactly how it should be done as you say, but I'm also keen to reuse existing HTML templates without having to re-factor too much (some changes would def be needed of course, but I'd rather avoid having do a major re-write of existing designs I have). I'm more looking to resuse my existing designs, but plug them into the same backend page class as they will be using the same data (just doing slightly different things with the data). I do like the idea of using the localisation functionality that Tapesty has. Just feels a little weird as I know that's not it's purpose. Thanks.

Re: Can you dynamically select which page template to return?
Hi. I just gave that a go, using localization to serve a different TML
template. Started by adding following lines to AppModule:
public static void contributeApplicationDefaults(
MappedConfigurationlt;String, Stringgt; configuration) {
configuration.add(tapestry.supported-locales, en,fr);
}
Then set locale programatically:
@Inject
private PersistentLocale localeService;
.
.
.
localeService.set(new Locale(fr)); (did this in Activate method of a super
Page class that all my page classes extend.
I have a page called Home.tml (Backed by Home.java which extends Page.java)
I renamed Home.tml to Home_fr.tml.
When I try to access this page however the broser navigates to /fr/Home. I
was thinking that it should just display /Home in the URL as before, but
serve the html from the new template file (Home_fr.tml)?
Thanks again!!
