[T5.2] Principle 1, Static Structure Dynamic Behaviour
Hi forum,
I have a question,
since T5.2 does't use a pages pool, what happend with Tapestry principle 1?
Now, can we have a more flexible component framework? :)

You are not violating the principle. The static structure we're talking
about is the page and component instances, not the result of their
rendering.

No problem at all. :)

Re: Injecting Tapestry Services into Spring beans
Posted by Jeshurun Daniel <sj...@yahoo.ca>.
Hi Kai,
Actually it was working all the time. I was injecting @Session instead of @Request to get a session and was getting the exception no Service implemented it. I was able to inject a (not null) request object, but the session in it was still null, probably because this was too early in the pipeline or something (this was in the authentication service). I did find a couple of workarounds for my requirements and maybe they will help you too.
I wanted to inject Tapestry services into spring beans for two reasons:
1. I wanted access to Tapestry's Messages service to inject some properties I had defined in app.properties. Instead of injecting messages I just did this
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>/WEB-INF/app.properties</value>
<value>/WEB-INF/security.properties</value>
<value>/WEB-INF/hibernate.properties</value>
</list>
</property>
</bean>
and then just using ${property.name} to inject the properties into my Spring beans.
2. I was using Spring's LDAP authentication provider and I wanted to store a User object in session once a user was successfully authenticated (and was hence trying to inject @Request). I got around this by extending Spring's LdapAuthenticationProvider and override its authenticate method. I was then able to store a user object in session like this.
@Override
public Authentication authenticate(Authentication authentication)
throws AuthenticationException {
authentication = super.authenticate(authentication);
if(null != authentication && authentication.isAuthenticated()){
HttpServletRequest httpRequest = globals.getHTTPServletRequest();
HttpSession session = httpRequest.getSession(false);
User user = new User();
user.setUsername(authentication.getName());
User daoUser = userDao.getUser(authentication.getName());
if(null != user){
// fill some user details from the database such as name and email
}else{
// I just send an email to myself here saying this user doesn't have a profile, even though they logged in successfully from the ldap.
}
}
session.setAttribute("sso:my.app.path.to.your.user.object.User", user);
}
return authentication;
}
You can just inject the user object anywhere in your page classes by using@SessionStateprivate User user;private boolean userExists;
There are two downsides to this.1. If something goes wrong at this point, the user gets a full blown container error page, instead of your pretty error page defined in tapestry.2. If you restart your servlet container when the user is logged in (not that you would do that in production), the session object disappears even though Spring security still says the user is logged in. I haven't found a way around this yet.
I hope this helps.
Thanks,Jeshurun

My Tapx library includes a component that reads an external template
file (as XML) and can render it as part of a Tapestry page, including
delegating parts of it to blocks, and processing expansions.
Documentation coming (but lower priority than T5.2 docs, so be patient).

Yes. I can think of two approaches:
1) Override or advise the Tapestry template loading service, so users can
edit templates.
2) (Strongly preferred) Use some templating engine like Freemarker to let
the users edit content and Tapestry for anything else. Tapestry templates
were always meant to be used by developers only, not end users, while
Freemarker and similar tools are way more suited for this task. Search the
mailing list for CMS for more discussions about this.

Hi
Actually, there is no problem if you do that since you generate a
valid action URL of your form and use request service to read
parameter values.
But this is not how Tapestry has been designed, Tapestry is a
component oriented framework, not an action oriented framework. Static
structure simply means that you cannot create *new* instances of
component at runtime. That does not mean that you as a developer can't
go beyond this principle and use Request.getParameter() method or even
generate plain HTML in dom tree
But if you use Tapestry components, you must be aware that even if you
put a component inside a loop, the inner component will be 'rendered'
n-times but ultimately there is only ONE instance of this component.

It stays the same. The difference is that there's only one instance for
every page.

We have a very flexible component framework. :) You only need to think
some scenarios in a little different way.

The documentation is in flux, but I actually just re-wrote that

Static structure referred to page pooling a lot, but it's really more than that.
