RE: T5: Preparing a pristine object for re-use
the default scope of a service is singleton.
i you want a new DAO on every request you
can annotate you method with :
@Scope(IOCConstants.PERTHREAD_SCOPE)
if you are using tapestry-hibernate you can have
your session injected into a singleton scoped
service and tapestry will take care of it.
please see the documentation and search the
mailinglist. there was a very good thread a week
ago
e.g.

T5: Preparing a pristine object for re-use
Hello,
I have a DAO that I want to re-initialize every time it is injected
(that is, the DAO has state that I want to reset to make it pristine).
I thought I could do it in the constructor for the DAO, since I am
defining the service as follows in my AppModule:
public static AccountDAO buildAccountDAO( Session prmSn )
{
return new AccountDAOImpl( prmSn );
}
But it appears the constructor is only being executed the first time the
DAO is injected, it is not being executed on subsequent injections. Am
I missing something?
Thanks,
Andy

Re: Simple servlet with xml output - to tapestry
Turns out the patch is too big to apply. Fernando, is it possible to share a build with the patch applied? I am sure other people will have the save need and would surely appreciated it thanks Thanos Fernando Padilla wrote: 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 ( br, , etc ). So essentially it outputs invalid xml. You might have to do some post processing to clean it up.. possible work around: If you need namespaces, or if you need to avoid the special html tag handling, you need to look at JIRA issue TAPESTRY-1600. Go there and vote on the bug, it also has a patch if you're stuck and feeling adventurous. I have been using the patch for over a month on production, and have gotten response from another person that they are pretty happy with it. Go vote for it, for some reason we have gotten zero response from the T5 developers on reviewing the patch.

RE: T5 how to control login state
Chris, Thanks for your insightful wiki on this subject. This seems a much lighter weight solution to the Acegi Authentication. ( the latter requires many more jar file downloads related to Spring) I do have a question that's been on my mind for some time now. Is it standard practice in Tapestry for page redirects to throw exceptions? Is there another method that preserves the current state after a redirection? Say for instance, a user bookmarks a page and returns to it two days later. How does one determine the resultant page after a successful login? Using the current code, the user's session would be invalid and forced to the login page when trying to access the bookmark via an exception. How would you save the destination url for the user after he/she logs in successfully? Rather is there a standard way that Tapestry does this? Would you have to put it into the ASM and then access the ASM during login to determine the users destination? Is there another mechanism?

Tapestry and the session manager won't recognize that you've made
changes to your locales Set unless you explicitly call
setSelectedLocales again.
I tried once to add a proxy mechanism to common classes like
collections and such so that Tapestry could automatically detect these
changes as well but it proved to be too error prone and cause problems
with hibernate / other persistence libraries.

Re: T4.1.4-SNAPSHOT issue migrating from 4.0.2 with PopupLinkSubmit
I think you need to pass in this to your script execute call, the
current method you are executing is deprecated.
For the javascript calls you can refer to
http://tapestry.apache.org/tapestry4.1/javascript/index.html
and
http://tapestry.apache.org/tapestry4.1/jsdoc/index.html
where you should find the new function tapestry.form.submit(form)

Which comes out as:

The Javascript we're rendering in PopupLinkSubmit.java comes out as:
function submitPopupLink(form, elementId, url)
{
var windowName = 'RDQGraphPopup';
var randomNumber = Math.floor(Math.random()*1000);
windowName = windowName+randomNumber;
aWindow = window.open(url, windowName, 'width=840, height=800,
scrollbars=yes,resizable=yes', false);
aWindow.focus();
var form = document.getElementById(form);
form.target=windowName;
form.events.submit(elementId);
form.target='';
}
I can supply the rest of the source if required but it's basically following
the example I mentioned at the top.
The rendered versions of the link and the Javascript are the same as under
4.0.2 but we get the above error in the back end and the link does not work.
We get a Javascript error stating that 'events' is null or not an object.
This is referring to this line:
Re: T4.1.4-SNAPSHOT issue migrating from 4.0.2 with PopupLinkSubmit
OK we updated the generated Javascript with the new version of the Javascript
function
function submitPopupLink(form, elementId, url)
{
var windowName = 'RDQGraphPopup';
var randomNumber = Math.floor(Math.random()*1000);
windowName = windowName+randomNumber;
aWindow = window.open(url, windowName, 'width=840, height=550,
scrollbars=yes,resizable=yes', false);
aWindow.focus();
var form = document.getElementById(form);
form.target=windowName;
tapestry.form.submit(form, elementId);
form.target='';
}
this seems to allow the popup link to work but we're still getting the errors
in the back end.
They don't seem to have any ill effect but they are generated each time the
page serves.
For script generation we are using the version of the call passing this:
getScript().execute(this, cycle, pageRenderSupport, symbols);
(If this is the call Jessie meant)
Any ideas as to what is causing the error? Even though it does not seem to be
causing any problems I've a feeling it's gonna bite us in the ass at some
point...

RE: T5 how to control login state
Thiago, I know that on pages or components navigation is controlled by the return type. ( page class, String, etc) My question has to do with how to deal with navigation before any page or component renders. In other frameworks you can have a workflows specified outside the application in XML, a database, etc. These workflows determine page flow. In tapestry, however this is not the case that I've seen. I've partially implemented what Chris just posted about the Dispatcher but using the RequestFilter like Massimo suggested. What I don't know how to do is to cleanly specify where to go after logging the user in without having to manually stuff something into the HttpSession about where to return in the page flow.

Re: T4.1.4-SNAPSHOT issue migrating from 4.0.2 with PopupLinkSubmit
No ideas are coming to mind right away, other than it looks like it's trying to do Map related functions without casting to map first. It is not a critical bug but it could potentially cause problems for you. Or at least be annoying to see during development and not as fast as it could be in production. I'll play around with this popuplinksubmit component later (maybe add it to contrib) and see what I can find.

Re: Moving on from 4.0.*
I can't speak to whether or not you should upgrade to T5 or how stable it is relative to your requirements, but can mention some things about Dojo versions. The packaged version of Dojo is sort of Dojo 0.4.3 but contains many local fixes not available in the official distribution - most being smallish bugs we've found in widgets / other things in various places. I'm not saying you are guaranteed to have your problems fixed in this version, but it may be worth looking at if you have the time / energy to do a quick glance. You can also attempt to replace the provided tapestry version with one of your own by overriding the AjaxShellDelegate renderer used in either the Shell or ScriptIncludes components: http://tapestry.apache.org/tapestry4.1/apidocs/org/apache/tapestry/dojo/AjaxShellDelegate.html I think Andy has something up his sleeve for 4.1.4 (4.1.5?) support for using different javascript libraries - which could possibly mean you can use Dojo 0.9 or similar. . It's really not ~that~ much work to make switching javascript libraries possible - it's just been low on my priority list and I've heard Andy mentioning doing something about it so I've ignored it The core supports using prototype dojo already, it's just a question of those few places that have library specific knowledge - such as the form related javascript. ...which I can see Andy has already been making generic for this purpose. I don't know, we can try and squeeze that feature in to the 4.1.4 release depending on what Andy has to say about it. It's really not as much work as people seem to think..

RE: T5 how to control login state
Chris/Thiago: Thanks for the responses. What I'm getting at is trying to see if it is at all possible to allow page flow control reside outside of code. The reason for this is that I don't want to have to make code changes if I want a different flow. Externalizing the workflow makes this possible. It also defines a clear path of execution for a given request. We currently have our workflows defined in XML, which is read in on applcation start. At any point in time during the execution of the workflow, I can print out it's expected route of execution. I'll know the entire decision tree up front before anything executes. Being that it is outside of code, I can view the workflow while the application is offline as well. Having a workflow engine can help differentiate code from business logic. Our current implementation resembles the State pattern I believe. Imagine this, there are a given set of instructions ( externally defined workflow); each represent an action a user can take within the application. ( ie search, open a document, etc). Each workflow can be composed of many steps or instructions. The application acts as the interpreter of the workflow. It makes no decision of its own. All it knows about is the current state of the workflow. The actions the application takes depends on the current state of the workflow. Each step ( state) defines a set of possible actions to take based upon the result of the last action which it passes to the application and which the application passes back to the workflow. By doing it this way, you can easily add new workflows without having to touch any code. For instance, you could combine a series of searches in one workflow. There are many open source workflow engines around. You can find a few at this link here: http://java-source.net/open-source/workflow-engines We currently have our own engine we implemented with our current architecture. I am trying to figure out a way to integrate it into Tapestry. As for my initial question, it seems that using the ASO mechanism you describe is the way to go for now. I agree with you that currently an answer probably lies in services. However, I'm not too familiar with Tapestry to the extent to understand how to hook up the AccessDispatcher/RequestHandler to some service that handles the redirection. I guess I need more detailed information of the request handling. From the docs, the service() methods return true or false. A true tells it processor the request has finished and false tells it to go on. After the dispatcher/requestHandler code executes what is the next dispatcher/filter in line? How can I find that out? Thanks again guys! --Michael -Original Message- From: Chris Lewis [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 07, 2007 2:31 PM To: Tapestry users Subject: Re: T5 how to control login state Michael, I'm pretty sure tapestry has no such mechanism. The short answer to your question is that you'd have to store these things (page names of failed/unauthorized access attempts) as an ASO, and then pull it out after logging in. I've not worked with a system like you're talking about, but am glad that T5 is lacking in XML. However something like this could probably useful, and may be doable in the form of some service. First of all I should point out the link to how you can implement a redirect exception: http://wiki.apache.org/tapestry/Tapestry5RedirectException This is a bit of a hack, but demonstrates how you can get the exception back, as well as use decoration. I think what you want is attainable through services, and probably as a dispatcher. I'll need someone with a more thorough understanding of T5 to chime in on this, especially someone that has used what you are looking for. If a dispatcher handles the request, it is responsible for sending the response (HTTP and content) to the client. With that you should have the basics for what you want. You may also have this option with RequestFilters, but I'm not sure. Anyway, someone with more knowledge on the workings would be good to hear. I'd like to know how you fare as I'm always in the market for a better way to do things. Sincerely, chris Nguyen, Michael wrote: Thiago, I know that on pages or components navigation is controlled by the return type. ( page class, String, etc) My question has to do with how to deal with navigation before any page or component renders.

I've partially implemented what Chris just posted about the Dispatcher but using the RequestFilter like Massimo suggested. What I don't know how to do is to cleanly specify where to go after logging the user in without having to manually stuff something

T5: Preparing a pristine object for re-use
Hello,
I have a DAO that I want to re-initialize every time it is injected
(that is, the DAO has state that I want to reset to make it pristine).
I thought I could do it in the constructor for the DAO, since I am
defining the service as follows in my AppModule:
public static AccountDAO buildAccountDAO( Session prmSn )
{
return new AccountDAOImpl( prmSn );
}
But it appears the constructor is only being executed the first time the
DAO is injected, it is not being executed on subsequent injections. Am
I missing something?
Thanks,
Andy

RE: T5 how to control login state
Hi, Though I'm still in the design phase of my work flow mechanism I would like to share it here as it seems you are looking for something similar. I store a Workflow Object in ASO containing a ListClass containing the pages to walk though, and a child WorkFlow containing a potential sub WorkFlow. I will initially populate these objects hardcoded when needed, but these could obviously come from any DataSource created at startup or page action. I have a GenericPage which all my pages extend and catches all action and form requests. It will redirect to the next page in the workflow object and remove it from the List. If there is a child WorFlow, the redirect page will be obtained from there until there are no more. This approach currently relies on using submits or action links, but can easily be altered to also work on pagelinks. I'm using a GenericPage because I already have one, but this could obviously also be achieved with a RequestFilter (or Dispatcher?? haven't looked into those yet ;-) Next to that I also will build a component to print out the workflow state giving me a generic navigation tool for all my wizards/workflows. I played with apache Shale-Dialog (with apache myfaces) for a while and liked the possibilities but found the configuration somewhat hard to get my head around. If you already have a code base that reads out your work flow config I don't think it will be hard to make this work with T5.
