Re: [T5.1] How do you advise ClassNameLocator?
Hi Steve, that is not true. Of course you can override ClasspathURLConverter as any service in Tapestry. On Wed, May 6, 2009 at 6:49 PM, Steve Eynon steve.ey...@alienfactory.co.ukwrote: Arr, yes, thanks Igor. The JavaDocs for ClasspathURLConverter even states it exists for OSGi (Eclipse) apps: This is a hook for supporting OSGi, allowing bundleresource and bundleentry protocols to be converted to jar: or file:. The default implementation currently returns the URLs unchanged. But alas, this service again is defined in the TapestryIOCModule meaning it too can't be overridden or advised. I'll override it in my current classpath fudgey way... To overcome overriding issues, maybe rather than providing one class to convert all urls we could contribute UrlConverters to handle different protocols?

Re: t5: usual practice for page test
Mostly our pages are kept quite clean and simple, so we write unit tests for business logic mostly, I use JUnit and sometimes Easymock for that. using test driven development for pages? No, (although thinking of looking at PageTester at some point) but we do some black box testing using Selenium currently just write the code, write a test after it is done for SVN commit? Nobody likes to admit this, but I confess to have done it on occasion :) just write the code, manually test the page? We see development with manual testing as a normal part of the development process (we don't even call it testing). I guess how much testing you can afford to do lends itself to how much time you have to meet your deadline, what has really helped though IMHO is developing and following best practices for Java and Tapestry, which generally improves the reliability of pages, readability (predictability) of the code, and is easier to maintain as you know what to expect. Some might argue that its not deal to work this way but if you re-factor your code a lot, the quality also dramatically improves. regards, Peter - Original Message - From: Angelo Chen angelochen...@yahoo.com.hk To: users@tapestry.apache.org Sent: Friday, 8 May, 2009 02:02:40 GMT +02:00 Athens, Beirut, Bucharest, Istanbul Subject: t5: usual practice for page test Hi, I'd like to know how others do the test for page? what I'm doing now is, write the code, manually test it until it works, that's the end. how you guys do this task: 1) using test driven development for pages? 2) just write the code, write a test after it is done for SVN commit? 3) just write the code, manually test the page? thoughts? -- View this message in context: http://www.nabble.com/t5%3A-usual-practice-for-page-test-tp23437084p23437084.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: Pause after successfull authentication
Ok let me try to explain my scenario in detail:
I have custom filter extending AuthenticationProcessingFilter. So as user
tries to logon i call attemptAuthentication method of custome class. After
user is authenticated SUCCESSFULLY i have to:
1- made extra checks based upon roles assigned to user. and have to send
user back to login page.
2- Need to set lots of extra info in session and logg events i DB
So as soon as user was authenticated successfully control transfers to
targetUrl defined without extra checks i need. This is main problem.
Now i override the onSuccessfullAuthentication method and put all extra role
checking and other stuff in it. It works. Howeever if if find some problem
in role i have to send user back to login page now with custom error
messages.

Re: Pause after successfull authentication
This is not an uncommon scenario, but surely this is a question for the Spring
- Aecgi forums. you will get a better answer there.
Now i override the onSuccessfullAuthentication method and put all extra role
checking and other stuff in it
I don't use Aecgi, but I don't think thats the correct approach, there is a big
message in the API that says (Do not use this class directly), you are also
overriding an event method as well, which may explain why you are having
trouble controlling redirection, instead you should probably look at using the
appropriate service i.e.: Use / provide a custom AuthenticationProvider, or at
least use an AthenticationManager implementation that is suited.

Try using lazy loading on getPage(), avoing calling

public BasePage getPage() {
if (page == null) {
page = (BasePage) resources.getPage();
}
return this.page;

T5: Passing named/structured-type params in URLs?
Hi, I've been using T5 to develop a scientific database Web frontend, and a requirement is that Web visitors need to be able to bookmark pages, i.e. the parameters of what paper, dataset, etc. have to be in the URL. Having looked at the Web documentation and the Packt book, it seemed that PageLinks are the way to do this... and that works very well for passing a single parameter of simple type (I tried Integer and String) via the URL. But it's passed in an unnamed way, i.e. PageLink'ing a parameter of value 1234 makes a URL like .../linkedpage/1234. I need to be able to pass a) one of several roughly equivalent single parameters (because the name of the parameter determines which of the bibliographic key schemes to use when looking up the paper in the database) b) optional extra parameters, to allow specifying only one particular dataset or even data axis in the paper to be viewed c) it would be good to be able to specify multiple datasets, e.g. to construct a bookmarkable URL which displays datasets 1, 2 and 4 of a given paper. I'd naively expect to be able to do this by passing a Collection of the values to PageLink, but haven't even tested if this works as I wanted to get your collective advice first! I can do these things by hand, and in fact am doing so at the moment, but it's by using normal URL query strings which is not really the Tapestry way. It also means that life is rather awkward as I have to manually do the URL encoding and getting the query params and context path by accessing the Request. Yuck. In short, I'd like to employ the Tapestry way of having a single page where various ways of slicing the data are accessed via a sort of URL API scheme semantically similar to this: .../view?p=1234 .../view?irn=12349876 (these first two are two ways to access all the data in the same paper) .../view?p=1234d=1 (view one dataset only) .../view?p=1234d=1y=2 (view one axis of one axis of one dataset only) .../view?p=1234d=1,2,4y=1,3 (view specific axes of specific datasets only... I wouldn't provide links like this, but users who want specific data might construct them themselves --- hence why I called the URL scheme an API) So, is there a Tapestry meachnism for doing something like this? I can do it right now, but I'd rather not have to fight the system. I would expect Tapestry to do it a bit prettier than what I've shown, maybe *something* like .../view/irn/12349876/d/1,2,4 (yes, there are issues with telling what's a param name and what's a value... I just mean this schematically) But right now I don't even know where to start looking! Help, please!? ;) Thanks in advance...

Just use a List as the activation context value. For each named parameter
one want, add the name first, the value second.
The above URL would be constructed by Tapestry if you returned a List
populated like this:
List list = new ArrayList();
list.add(irn);
list.add(1245569);
list.add(d);
list.add(1,2,4);
Then, declare a onActivate(EventContext context) method and reconstruct
the pairs:
for (int i = 0; i context.getCount() / 2; i++) {
String name = context.get(String.class, i * 2);
String value = context.get(String.class, i * 2 + 1) // instead of String,
you could use any type here
}
I have not tested this code, but I guess you get the idea. ;)

Re: T5: Passing named/structured-type params in URLs?
That should work.
I think it could be interesting, though, if tapestry provided an
additional persistence mechanism, ala:
@Persist(PersistenceConstants.QUERY_PARAMETER)
private String p;
@Persist(PersistenceConstants.QUERY_PARAMETR)
private Integer irn;
which would then take the values in p and irn and stash them in the
url, like:
p=valueEncodedValueirn=valueEncodedValue
Obviously this wouldn't be appropriate to use everywhere; if you're
concerned about users tampering with URLs, you'd want to avoid it.
But in cases like that presented below, where you expressly want users
to be able to muck about with parameters, it would be useful.
Note that this is similar to the current client-side persistence
mechanism, except that mechanism a) rolls all persisted values into a
single parameter and b) base64 encodes the parameter.
As long as you've got the basic mechanism for doing the above, you
could translate it into a pretty url via url rewriting without too
much trouble.
Thoughts?

Just use a List as the activation context value. For each named
parameter one want, add the name first, the value second.
The above URL would be constructed by Tapestry if you returned a
List populated like this:
List list = new ArrayList();
list.add(irn);
list.add(1245569);
list.add(d);
list.add(1,2,4);
Then, declare a onActivate(EventContext context) method and
reconstruct the pairs:
for (int i = 0; i context.getCount() / 2; i++) {
String name = context.get(String.class, i * 2);
String value = context.get(String.class, i * 2 + 1) // instead of
String, you could use any type here
}
I have not tested this code, but I guess you get the idea. ;)

Clarification on discardPersistentFieldChanges
Hi, I have a question about ComponentResources discardPersistentFieldChanges. The page in question is a configuration page and contains a large number of components that each have some persisted state and I'm currently calling discardPersistentFieldChanges on the page onSubmit.. I want to make sure that all persisted state is discarded for the page as well as for all components used in that page. The documentation for this function says: Discards all persistent field changes for the page containing the component. My reading of this is that I can call discardPersistentFieldChanges on any component on the page and it will discard all persistent field changes on the page and on all components used in the page. Is this true or do I need to explicitly call discardPersistentFieldChanges on each component? Thanks.

Have you tried Request Parameters. They do the job well. See:

Re: T5: Passing named/structured-type params in URLs?
Right.
You can certainly use request parameters, and the poster, in fact, /
is/ using request parameters currently.
But that's painful. You have to manage the parameters and wrangle
type coercion manually. If you're doing this a lot, that's a lot of
repetitive boiler-plate code.
Which sounds exactly like something tapestry should be able to take
care of for you. Sort of like how the @PageActivationContext makes
life a lot easier for the pages out there with a single activation
context.
