Re: T5 which button did you hit?
There are some docs about this here:
http://tapestry.apache.org/tapestry5/tapestry-core/guide/event.html
To get the "success" event from the component named Form, use:
onSuccessFromForm()
To get the "submit" event from the component named Submit, so use:
onSuccessFromSubmit()
It's good practice to add a t:id="ComponentName" to your components.
(Otherwise the default name is the component type.) Then you can use:
onEventFromComponentName()
Cheers,
Nick.

T5: How can I inject a different resource type?
Basically, I want to be able to store my component .tml files in a database. I've been looking at the code, stepping through the debugger, and it seems that I need to implement org.apache.tapestry.ioc.Resource or perhaps extend AbstractResource. ClasspathResouce and ContextResource are classes that already extend AbstractResource. I assume these are what load the .tml files either from classpath or from a file on the context. I'm having trouble navigating the code to the point where I could tell a component to choose a resource( content of .tml) from an alternate storage. Can someone point me in the right direction? I'm not afraid of editing tapesty base code if I have to, although I'd rather not (perhaps I can inject a custom implementation?) I'm scared I might be limited to providing the .tml content via URL..is that so? Thanks Michael Lake

Re: Help with forgetPage method
lalap, Using the back/forward button on the browser invokes the browser's internal caching mechanism and is largely beyond the scope of the server (tapestry) to control. It is when the browser is *redirected* back to that page or when the contents of that page are streamed back to the browser from some listener method that the session data for that page and that particular user will be "forgotten."

Re: T5: Will there be OGNLsupport
It's possible, but there are probably a couple things that need to be addressed properly first.

I plan on doing this at some point but am still trying to keep up with bug reports first. Of course, it is an open source project - so anyone can try and help with that if they want.

Re: Simple servlet with xml output - to tapestry
Yes you can output XML directly from the template with some caveats.
1) By default the contentType is "text/html", if you want to change that
you can override it by using this annotation on your page class file:
@Meta("tapestry.response-content-type=text/xml")
2) namespaces are totally ignored and stripped out.
3) if you use any of the special html elements, then it uses the old
html method of not actually closing the tags ( , , etc ). So
essentially it outputs invalid xml. You might have to do some post

Re: Mixing T5 and Guice --- best practices
You may run in to issues wrt hot class reloading, but maybe not. Only one way for you to find out. ;) FYI - I was witness to at least a couple tiny email exchanges between Howard and Bob discussing their implementations and what kind of options there might be. The T5 IoC feature set is just too rich to be handled by Guice right now without a lot of work being done on the Guice side. Just didn't want people thinking that Howard just blindly does his own thing without collaborating with anyone. They both understand the issues involved and seem to sort of agree that things really do work a little differently in many areas. Maybe someday Guice will support all of the features T5 needs, but in the meantime it doesn't - so there's not really anything that can be done about it without a lot of re-write work being done in Guice.

I think the T5 IoC is great, fast, simple and covers 80% of the things you need an IoC container for. Plug, allows you to override a great many parts of tapestry which, to me, is a great value. Contributions, I wont even mention (myself a long time RCP developer, I consider them a must). Furthermore, if you need a more powerful container (like spring or something) you can always plug it in via an ObjectProvider. The only things that might be missed at the moment is: a) You can't use decorators on pages and components (you could us the request processing chain of command, but that might not be so expressive) b) decoration of multiple services might not be as expressive as one would like it to be if one would like use declarative transaction management.

That page says:
"Note: Another idea will be other ways of matching services: base on
inheritance of the service interface and/or based on the presence of
particular class annotations on the service interface. None of this has
been implemented yet, and can readily be accompllished inside the
decorator method (which will return null if it decides the service doesn't
need decoration)."
Well, it's not entirely true. If you write a @Match("*"), Tapestry-IoC
throws an exception telling that you cannot decorate internal Tapestry-IoC
services. I'll file a JIRA about this.

Re: T5: Persist or not? help me understand this
Angelo, We had a situation using T4.1 where some non-persistent properties where reused in listeners after the page was rendered. It used to work relatively fine but as the page got more properties it begun to fail. Sometimes it got the right value, other times an old value (?!?!) and - what happened more often - it switched from null to the right value as I clicked again and again in the link for the listener. Setting it to persistent seems to have fixed the problem. -- Marcelo C.

I think the T5 IoC is great, fast, simple and covers 80% of the things you need an IoC container for. Plug, allows you to override a great many parts of tapestry which, to me, is a great value.

Re: T5: Multiple onActivate?
In some ways I'd agree, in others I wouldn't. I'm finding cases where T5 really made some simple well-defined aspects from previous generations much more difficult than they need be. These will be getting added to JIRA though. All in all though, I do like a lot of the improvements. I'll have to check out Alexander's book I suppose as well, since the documentation is a bit lacking at the moment. -- Kevin On 10/30/07 9:05 PM, in article [EMAIL PROTECTED], "Marcus" <[EMAIL PROTECTED]> wrote: > Kevin, > > On this process, T3 ->T4 ->T5, just keep in mind that Tapestry 5 is much > more simple. > > Marcus - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Simple servlet with xml output - to tapestry
Hi all, I am currently testing tapestry and trying to convert a simple servlet. I have a typical servlet that gets parameters and returns xml for example http://localhost:8080/myapp/method=login&user=test result: ok after that, return results for user stored in session http://localhost:8080/myapp/method=info test so basically I want something similar in tapestry that: - will accept parameters - will use xml as templates and will generate xml results - will persist the user credentials into the session My biggest concern is '2' (xml output). Its not clear to me how should I configured it. Should it be a service or I can just edit the template (can't make it return xml). I am still trying to become familiar with tapestry so I can't completely understand some forum results regarding outputs. I am using version 5.0.5 Any advice would be very much appreciated.

My first Seems obvious that a transaction should be wrapped around the form validation (or around the whole request) which would rollback in case of valdation errors. The question is - how to do it? Better yet, how to do it without boilerplate code all around? tapestry-ioc allows you to write interceptors on service method calls. I don't think it allows you to write such interceptors around components and pages. I remember that one of the good things you'd get when you'd combine struts 1 and spring was that allowing spring to create your actions you had full control over when and where transactions started and ended. I think that it might be a drawback that tapestry 5 does not allow you to use the IoC containers AOP facilities on components and pages. Ognen P.S. In my Eclipse-RCP project I also use JSF's approach: values are kept in the controls (field components) until the form is submitted (ok pressed). -- Ognen Ivanovski | [EMAIL PROTECTED] phone +389 -2- 30 64 532 | fax +389 -2- 30 79 495 Netcetera | 1000 Skopje | Macedonia | http://netcetera.com.mk - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5: Persist or not? help me understand this
Hi,
looks like I have to make it @Persist if Long usrID is private, if just the
default it might be persisted even without a @Persist but a warning during
run time, am I right?

T5 : Localization of input validation
Hi, I can't find the way to localize the default messages provided by Tapestry for input validation like : "You must correct the following errors before you may continue" or "You must provide a value for ..." Any help is welcome. Stephane
