Re: T5 5.0.10: ComponentResources.createActionLink broke after upgrade from 5.0.6 to 5.0.10
Right. The javadoc of createActionLink doesn't tell anything when it should be used. To my opinion, it makes sense to allow it be used in event handler methods.

T5 5.0.10: ComponentResources.createActionLink broke after upgrade from 5.0.6 to 5.0.10
Hi All,
I am experiencing a error of using ComponentResources.createActionLink
after upgrade from 5.0.6 to 5.0.10. The code used to work now broke.
The Stack Trace is :
==
Caused by: java.lang.NullPointerException
at
org.apache.tapestry.internal.services.LinkFactoryImpl.collectActivationContextForPage(LinkFactoryImpl.java:217)
at
org.apache.tapestry.internal.services.LinkFactoryImpl.createActionLink(LinkFactoryImpl.java:129)

at
net.memberdirect.mdsb.pages.trial.DemoActionLink.onActionFromLink1(DemoActionLink.java:18)
==
The code snippet is:
===
public class DemoActionLink
{
@Inject
private ComponentResources componentResources;
@SuppressWarnings(unused)
private Object onActionFromLink1()
{
// Some Business logic
// Navigation logic
return this.componentResources.createActionLink( Link2, false
);
}
@SuppressWarnings(unused)
private Object onLink2()
{
// Some Business logic
// Navigation logic
}
}
==
What I noticed in 5.0.10 source code is that
ComponentResources.createActionLink is either called from beginRender or
afterRender method only. Does that imply that we cannot use it in event
handlers?
Cheers,
Jeffrey Ai

Re: T5: A web flow idea on T5
Be careful that the problem might not just be having 2 flows at a time for the same session but also managing interrupted flows. I think allowing one flow interrupted by another will introduce lots of complexity and consume more resources. I don't think our users need it, so I don't want to overkill. If a new flow starts, we will just simply clear the existing flow. I don't know much of T5 internals: is the persistence strategy system so different from T4? I start to use Tapestry since T5, so I don't know the difference. But I guess it's similar. Basically you could choose the session strategy, flash strategy or client strategy. Also fields annotated as ApplicationState are shared by all pages. You could find more information in the T5 guide.

Re: T5: A web flow idea on T5
Thanks for you comments! in the step 3 if the specific page would to render the next link, what is the purpose of the WEBFLOW? The next link in that page is populated by the WEBFLOW, so it's still the WEBFLOW controlling the navigation. isn't the WEBFLOW'S responsibility to take care of the page navigation?? well i guess the purpose of having such a concept of WEBFLOW is to decouple the Page presentation from the page navigation Exactly! so upon the action, say delete from MyCRUD, MyCRUD::onDelete() was first invoked , then the return value (business specific, could be an Object to be deleted) will be pass to DeleteConfirmationPage, and invoke the @EntryPoint confirmationEntry The point is: in some case, the next page needs to by dynamically decided by the WEBFLOW based on the data user inputed so far. Therefore, the next page might not be DeleteConfirmationPage, but some other page. Spring framework webflow supports this by configuring conditions in XML. But I think using Java is much simpler and testable to developers.

Hi Jeffrey,
What you do is change the submits and the links to look the same,
which is not quite the same as the browser-generated button, but on
the plus-side they'll look the same in any browser. This approach is
used in many commercial sites eg. banking sites. One place that
describes button-styling is
http://particletree.com/features/rediscovering-the-button-element/
.
eg. Here are 3 buttons on a UserEdit page:
div class=buttons
input type=submit value=Save/
Refresh
Cancel
/div
and here's some css to style them to look the same:
.buttons a, .buttons input { margin:0 7px 0 0; background-

padding:5px 10px 6px 7px; /* Links and submits */ }
.buttons input { width:auto; overflow:visible; padding:4px 10px 3px
7px; /* IE6 */ }
.buttons input[type] { padding:5px 10px 5px 7px; /* Firefox */ line-
height:17px; /* Safari */ }
*:first-child+html input[type] { padding:4px 10px 3px 7px; /* IE7 */ }
.buttons input img, .buttons a img { margin:0 3px -3px 0 !important;
padding:0; border:none; width:16px; height:16px; }

T5: A web flow idea on T5
Hi All,
As you may know or not, T5 doesn't have a web flow framework like the Spring
one yet. Howard mentioned he may add it in the next release. However, our
project cannot wait for that, therefore I have created a simple one on T5.
Here is the general idea, your comments are **GREATLY APPRECIATED**.
* A WEBFLOW, which is a normal T5 page, injects and contains PAGEs that
will used in this web flow.
* A PAGE can be used in multiple web flows. A PAGE doesn't have any
knowledge of where to go for next page, previous page or cancel link. All
these knowledge are dynamically populated from a WEBFLOW.
* A WEBFLOW has some data objects, which are annotated as @ApplicationState.
PAGEs can pick up whatever data they are interested, display them or
populate them.
* A typical request flow is like below:
= An action request is post back to a PAGE
= A PAGE will do some validation and populate the data
= In onSuccess() method in PAGE, it returns the next page link, which is
populated by WEBFLOW and pointing to an action in WEBFLOW
= A redirection action request is sent to WEBFLOW
= Some onPage() method in WEBFLOW is triggered. It could review the data ,
decide the next page and return it.
= A page render request is sent to the next page
Here are some code snippets :
public class WebFlow
{
@InjectPage
private WebFlowPage1 page1;
@InjectPage
private WebFlowPage2 page2;
@InjectPage
private WebFlowPage3 page3;
@SuppressWarnings(unused)
@ApplicationState
private SomeObject data;
...
private Object onStartPage()
{
page1.setNextPage( componentResources.createActionLink(
page1, false )
);
page1.setCancelLink( componentResources.createActionLink(
cancel, false
) );
return page1;
}
@SuppressWarnings(unused)
private Object onPage1()
{
page2.setNextPage( componentResources.createActionLink(
page2, false )
);
page2.setPreviousPage( componentResources.createActionLink(
startPage,
false ) );
page2.setCancelLink( componentResources.createActionLink(
cancel, false
) );
return this.page2;
}
@SuppressWarnings(unused)
private Object onCancel()
{
this.clean();
return this;
}
}
public class WebFlowPage1 {
@Persist
private Link nextPage;
@Persist
private Link previousPage;
@Persist
private Link cancelLink;
@ApplicationState
private SomeObject data;
@SuppressWarnings(unused)
private Link onSuccess()
{
return nextPage;
}
@SuppressWarnings(unused)
private Object onActionFromPreviousPage()
{
...
return previousPage;
}
@SuppressWarnings(unused)
private Object onActionFromCancel()
{
return cancelLink;
}
...
}

Jeffrey Ai

Re: [T5] injecting services into Domain Objects
as pointed out by jeffrey i could also pass in the services as needed but i think this approach will bloat the methods of my domain objects. have you used this approach on a big codebase? doesn't it have some negative effects on the expressiveness of the Domain Objects? When some domain logic need to use some service, I think there are 3 ways to get that service : * passed as parameter * injected into domain object * pulled the service out from some registry in a method To my humble opinion, passed as parameter is the most clean way to make domain object reusable. For example, if you have an Order domain object, needs a TaxCaculator service in some method. You could pass either a USATaxCaculator or CanadaTaxCaculator in. The other ways don't provide this flexibility. Only if you are sure that a service will only have one implementation in your system for domain object use, you might choose the 2nd or the 3rd way. In this case, I am favoring the 3rd way. P.S. We have used the combination of 1st and 3rd way in a medium-scale e-commerce software.

Re: T5: Edit page best practice - Mk III
Geoff, I think your code is great for **ONE** edit-page.
Our project is looking for a web flow from T5, like the Spring one.
Do you have any idea about it?
Howard mentioned he may add this feature in the next release.
Might be a little late to us, but I am expecting to see it.
Cheers,
Jeffrey Ai

Hi,
In search of best practice for an edit page, here's my 3rd attempt.
It's looking pretty clean-cut to me, but I'm looking for suggestions
on how to improve it further.
private Long _personId;
@Persist(client)
// Persistence is needed here because this is a detached Entity
Bean. When we call the service to
// accept our changes, it will need its id and version fields intact
to be able to do optimistic
// locking check and a successful merge. client is used so that
even if you use the Back button
// to get to this page, we will have the right Person object.
private Person _person;
void onActivate(Long id) throws Exception { _personId = id; }
Long onPassivate() { return _person.getId(); }
void setupRender() throws Exception {
if (!_form.getHasErrors()) {
_person = getPersonService().findPerson(_personId);
}
}
void onValidate() throws Exception {
if (...a bit of validation logic detects an error...) {
_form.recordError(...);
}
}
Object onSuccess() {
try {
getPersonService().changePerson(_person);
_nextPage.onActivate(_personId);
return _nextPage;
}
catch (Exception e) {
_form.recordError(ExceptionUtil.getRootCause(e));
return null;
}
}
void cleanupRender() {
_form.clearErrors();
}
Some notes:
1. Detached object - Person is a detached entity. I am deliberately
avoiding refreshing it every time in setupRender() because a) it would
overwrite the user's changes, and b) it would defeat optimistic
locking: if someone else has changed the object then I DO want
getPersonService().changePerson(_person) to reject the transaction
when Save is pressed.
2. Thread-safety - I'm using client persistence to avoid the whole
thread-safety issue caused by the user opening a new window or tabs in
same browser (T5 can't tell them apart so they share the same
HttpSession).
3. onPrepareFromForm() - I'm avoiding it because it gets called too
often (something to do with rewind?). setupRender() seems better
for the job. Any downside t this?
4. cleanupRender() - if/when 5.0.7 uses flash persistence on the
form's ValidationTracker then I'll ditch this method.
Suggestions please!
Thanks,
Geoff

Re: [T5] injecting services into Domain Objects
is it possible to use tapestry-ioc to inject services into domain objects?
First, I don't think it's good practice to inject services into domain
objects. If some operation of domain object really needs to use a service,
you could pass a service instance to that specific method instead of
injecting it.
To my understanding, Tapestry dependency injection is mainly for services.
You could inject a dependency as a parameter of the service builder method,
or as a parameter of the service implementation's constructor(for autobuilt
services), or as a parameter of the module builder's constructor.
when using (build-time) AOP i need a reference to the registry, but how do
i get it?
The default Tapestry application registry is created in TapestryFilter, and
I don't see it's published out.
You could of course create your own registry using RegistryBuilder and
publish it somehow, but I don't think that's a good practice to have a
registry in your class and retrieve services from it.
Cheers,
Jeffrey Ai

Re: T5: Possible Literal Binding bug
It's hardly to say it's a bug.
I guess T5 will assume you meant to use literal binding when you use a value
with expansions, like ... ${val1} ... ${val2}.
So literal prefix is only necessary for a simple value, like abc.
Cheers,
Jeffrey Ai

Hi there,
I'm new to T5 so the I hope this isn't just a user misunderstanding but

having troubles with the prefix literal:
Page class:

A Template that uses MyComponent as follows:
t:myComponent t:title=literal:Page ${pageNo} of ${pageCount} /
The resulting output is:
literal: Page 1 of 3
If I change the parameter to use literal as the default binding the
output
correctly omits the literal: prefix.

Does anyone else have any need to use 'java.text.MessageFormat' style

Re: Nightly docs fixed - and some general notes
It's great to know that you are 100% on T5. Also I would like to put one vote for the web flow feature. I had a demo of T5 last week to other developers in my company. We are all exited about its clean code and extendability. The only feature we need but it's not in T5 is the web flow. Besides that, performance is a minor concern of mine. I did see some code are commented as naive implementation when I went through some source code. Cheers, Jeffrey Ai Howard Lewis Ship wrote: The nightly docs are now fixed. My hatred of Maven is growing quickly. You may not be aware of this, but Jesse fixed the Surefire plugin for Maven almost two years ago and that STILL isn't the default version (i.e., the non-snapshot version). In order to get some new tests working, I had to upgrade to TestNG 5.7, and for that to work, I had to enable Maven plugin snapshots to get the fixed Surefire plugin. That's been breaking other stuff, for example, the surefire-report plugin doesn't seem to be compatible with the fixed surefire plugin. I'm investigating Buildr, which is a Ruby based build system that understands Maven dependencies. It looks very promising. There's something of a Goedel issue in using Java to build Java, so I eagerly embrace using another language (Ruby) to build Java instead. Anyway, I had to strip out the surefire reports (like anyone reads them --- code coverage reports are more useful) in order to fix the build. People have been asking a lot about when T5 will be finished. I'm doing some work on it right now, while I'm on vacation. I have new clients lined up, so I'll be working in T5 as I finish T5. I'm no longer with Feature50, which means that 100% of my time is now devoted to Tapestry. I'm happier than I've been in months ... and there's more and more interesting news coming soon about the future of Tapestry. When will it be finished? There's a four page bug list, plus a lot of Ajax features to go. I'd still like to put in some Spring Web Flow support (but that may wait for a follow-on release), and beef up the Hibernate support. I haven't even looked at performance and optimization yet (pretty hard to tell, considering how fast the framework runs). I wish I could snap my fingers and just declare it done, but to be clear, I want it to be completely useable first ... and I'm trying to get to that stage as fast as possible. -- Howard M.

T5: Why value of CheckBox get lost at validation result page
Hi Folks,
I have a form with some TextField and CheckBox.
I add the onValidate() method into the page to do my own page page
validation like below:
===
void onValidate()
{
if ( )
_tracker.recordError( validation error... );
}
===
The data in the action request get correctly validated, and the validation
error message shows up in the result page.
However, all values of CheckBox get lost, at the mean time, all values of
TextField are still there.
The way I found to get around this problem is make all CheckBox fields
Persist(flash).
The same problem applies to Select component too.
Is this a problem? Why it's happening? Is my walk-around of this problem
good?

Re: T5 - validation of composite components
I havn't tried this, but I think it will work. If your composite component inherits AbstractField, you could override processSubmission() method to do your own validation. Actually, this is how TextField component do the validation. Cheers, Jeffrey Ai Markus Fischer wrote: I have a problem implementing proper validation of composite components. Assume I have a component consisting of two text fields. For validation, I need to consider the contents of both. The way I understand validation, it works thusly: 1. All fields within a form are asked by the form to pull their values out of the incoming request and validate these values (each validating its own value) 2. Form emits a validate() event which is propagate UPWARDS in the component hierarchy. Therefore, my composite component gets notified to pull its values out of the incoming request (which it can't, but its text fields will do), but never sees the validate() event, as it is within the form and thus below it in the component hierarchy. So, in effect, each text field can validate its own value, and anything above the form can validate the component, but the component cannot validate itself. Is that correct? What am I missing? Is there a way to get a validate event trigger in a component once the child components have restored their values and have validated themselves?

but that doesn't seem to solve the problem.
Thanks in advance,

Re: How to initialize a session variable in a page render request?
Thanks Lasitha. I did a search later of all guide. It's only mentioned in the page navigation guide. I still think it should be mentioned in the life cycle guide. I think that's the first place for developers to look for that information.

Re: [T5] tapestry-spring and WebApplicationContext
But my injection of the WebApplicationContext is not in a page but in
another class. Is it a problem ?
I think it will be a problem.
I believe Tapestry will only handle those classes in the package you defined
in tapestry.app-package in web.xml.
You could try to move it to see how things going.

In this page in Limitations chapter it is writte that we can't inject

and use it.
But I don't know howto retreive this so famous WebApplicationContext
when I'm in a tapestry code page or component.

Re: How to initialize a session variable in a page render request?
Well, in the life cycle guide, it is said it could be used for
initializations or caching.
Actually, I have confirmed it could do that, but just it doesn't work to
retrieve and mutate persistent variables.

Re: T5 persisting select component selection after form submission
Hi Ritesh,
I am not quite clear of your problem.
When I don't use any render phase or event it persists the value
And you say if you use any render phase the value is not persisted.
Persists to where? Do you just mean, in the action request, the value is
correctly set to a variable in your page?

Hello everybody,
I am newbie to Tapestry. I am using Tapestry 5 for developing
an application and I encountered following problem if anyone
suggest a solution it will be very helpful for me. :)
I have a select component with GenericSelectModel which shows
values well on first display. When I select some option from this
select component and submit the form I have to persist the selected
option, but it does not. :
I am fetching values for this model from database
on @SetupRender phase (tried onActivate(), pageLoaded() also - same
problem occurred).
When I don't use any render phase or event it persists the value but
when some options are added in database from other page it does not
fetch the current saved options in drop down list (since no render phase
or event).
This the source code I am using -
@SetupRender
void setValues(){
ListSomeBean bean= new ArrayListSomeBean();
bean.addAll(myDao.getBeanList());
someBeans = new
GenericSelectModelSomeList(dev,SomeList.class,name,id,access);
}
public GenericSelectModelSomeList getSomeModel() {
return someBeans;
}
Does anyone faced this problem and have solution please let me know.
Thanks in advance. :)

Re: T5.0.6: Table with input fields inside a form?
I wouldn't suggest you to use Grid component. The easiest way is to use
table directly with some tapestry components. Your template will be like
below:
==
table
colgroup
...
/colgroup
tr class=header
...
/tr
t:loop source=your_value_list value=your_value t:volatile=true
tr
td class=required
input t:type=checkbox value=your_value.boolean_value/
/td
td class=string${your_value.label}/td
td class=required
input t:type=textfield value=your_value.text_value/
/td
/tr
/t:loop
/table
The posted data in your action request will be automatically populated to
your_value_list.
cheers,

Re: How to initialize a session variable in a page render request?
Thanks, Josh.
onActivate() solve the problem. I thought this method only get called for an
action request, not for a page render request.
Apparently, I am wrong. I think it should be documented at the following
Page Lifecycle guide.

I can't tell you why pageAttached doesn't work (haven't tried it) but you
can use onActivate, or if it's for a form onPrepare.

Re: Tapestry 5: running tutoriel
Eli, Your mvn command should run without any manual download or settings. I have seen the similar error message before. My problem is caused by a broken maven plugin in my local repository, which is gotten from our incorrectly-configured repository server. I would suggest you to try the following things: * Remove your $HOME/.m2/repository/org/apache/maven/plugins/maven-archetype-plugin or move it somewhere else * If you have $HOME/.m2/settings.xml setup, move it somewhere else * Try to run the command again. This will make you redownload the plugin from maven central repository, which should work. Good luck!

Re: url-rewriting in Tapestry 5
You could use urlrewritefilter to rewrite both inbound and outbound URLs. But for outbound URLs rewriting, urlrewritefilter could only rewrite URLs encoded by HttpServletResponse.encodeURL() method. I believe most URLs generated by Tapestry components(so far only confirmed BeanEditForm) are using this method. Cheers, Jeffrey Ai Britske wrote: Thanks these all seem valid approaches. What i'm looking for is a stretching the possibilities i guess but here it goes anyway: I want a way in which I can plug a 'rewrite strategy'. This means that not only I have to translate urls from 'nice' to 'tapestry5' -internal but also the other way around, so that tapestry-pages reference other pages automatically by their 'nice' -url. I would like to keep the code in 1 place for making this bidirectional-translation. Doing this with mode_rewrite does't give me control in code I think.
