Thanks Thiago.

Although that begs the question as to why there is a getFilePath().

It isn't a bug. For security reasons, browsers usually don't report the  
path.

T5: UploadedFile problem

[Newham, Cameron]

Hi,

 

I notice that:

 

getFileName()

 

and

 

getFilePath()

 

of UploadedFile return the same thing (the name of the file) on Windows.
This seems to be a bug. I'd like to get the path - is there any way to
do this?

 

 

Thanks,

RE: Dynamic combo box - Tapestry 5.2.2

[Newham, Cameron]

The biggest problem I have with using Zones for dynamic combo boxes is
that the browser back button causes the whole thing to fail from a user
perspective.

Tapestry doesn't solve this out of the box - which is rather
disappointing.* Especially when it is advertised how easy AJAX is to use
with Tapestry.

I found it all to frustrating and gave up and returned to using some
Javascript to submit a form on combobox select to do the dynamics. Slow
- but at least it works.

c.


* of course, I'm always happy to have any error in my thinking pointed
out, but from an earlier question I asked on this list it appears that
this is a known issue with AJAX and the only way around it is to use
third-party hacks.

RE: Noticed another stackoverflow question on Tapestry 5, go vote

Bit of an odd statement!

I'm using Hibernate with Spring and Tapestry and you can use multiple
data sources with that solution. No hacking involved.

I never have used Tapestry-Hibernate.

True,

But they have forgotten to ask if the original poster wants to use
multiple
databases, if so i wouldn't encourage using Tapestry (sigh).

For me this is one of the biggest letdown's , i have written 2 apps in
Tap
5.2 who both require access to multiple datasources, but the inability
to
use multiple databases (through tap-hibernate) has required me to do
some
hacking around to get this working.

If i knew this beforehand i dont think i had choosen Tapestry.. 

On the other hand i think the framework is great and provides me with
enough
flexibilty to do what i want to do.

RE: Discussion

[Newham, Cameron]

Some people just have an enormous chip on their shoulder and love to
shout about it.

There are some pretty serious projects out there using Tapestry, if I'm
not mistaken. I don't see why someone wouldn't have it on their
short-list of choices if starting a project.

I think the only serious point these denouncers have is the lack of
documentation - but even that has been addressed.

Wow. Thank you very much.

Indeed, as I upgraded to 5.2 a couple of days ago I'm pleased to see
I've been running your final stable release.

I see the Wikipedia page has had a clean sweep - perhaps controversially
removing references to earlier versions.  Mmmm - they must have been

I dont like this way of refering to nodes (  document.entryForm.oosComment )
i'm not sure how many browsers fully support this but it looks like
this can work
when nodes have the name attribute set.

If i remember correctly, T5.1 used to include a name in each form but
this was removed
in 5.2 - see https://issues.apache.org/jira/browse/TAP5-796

So, anyway, see if your nodes have id, and just reference them in that

document.getElementById or prototype's $$

Hi,

The reason that it did not work is because you have to handle the event
onUpdate in your page otherwise it throws a NPE. I have modified that
and
indicated that in bold.

The alert that you saw was a debug alert...(Oops!!).

Further to this.

The part I think I am not understanding that is critical to the operation of 
this is:

resources.triggerEvent("update", new Object[]{value}, callback);
value = callback.getResult();

getResult() is always null. So I'm failing to understand how you are getting 
value set (it triggers an event - but...?)  Sorry if this seems obvious, but it 
unfortunately isn't to me.

LOL. When people say this it usually isn't! And I'm afraid my knowledge of AJAX 
and Javascript make your code fairly impenetrable to me. When I use your code I 
just get a dialogue box tell me that the page says {} was returned and the 
value on the page is printed as undefined.

I've read your follow-up below and looked at the code and understand the gist

Hi

It is very simple. In ProgressBar#afterRender an event "timer" is created
which is passed on to javascript. Javascript is a periodicExecuter
with period passed as a parameter. For each period it calls the event url
with the previous value of percentage as a parameter.

When the event is called onTimer() method is invoked in ProgressBar which
triggers an update event and expects a percentage value.
It then returns this percentage as a JSON object to the javascript ajax
call.

Finally javascript calls the method passed as clientFunc parameter of the
ProgressBar. In case the percentage has reached 100, it stops the
PeriodicExecuter

The AJAX part itself is completely Tapestry-unrelated and there are many  
examples in the Internet, maybe even in this mailing list archives. I  
answered something similar yesterday. The AJAX Prototype documentation is  
here: http://api.prototypejs.org/ajax/Ajax/Request/.

No, as long as you write your own JavaScript code to do and handle an AJAX  
request and then update the page DOM.

> Also, would the % value updated by my process just be held in a @Persist
> field?

Absolutely no. Just get the % value when handling the request. You don't  
even need a field for that.

T5: Progress indicator and AJAX example?

[Newham, Cameron]

Hi,

 

Can anyone point me to an example of a progress indicator or, more
simply, how one would go about having a page with a % complete field? I
have a process that ingests a file and takes quite a long time and I
would like to indicate to the user how much of it has been done.

 

I recall from research I did a few months ago that there is a progress
bar in one of the T5 component archives but there are no examples as to
how to use it and I'm not even sure if it works.

 

I imagine that if I wanted just a simple field on a page that updated
with a % then I would have Javascript make an AJAX get and obtain a
value from the server. However, as I'm a complete newbie to AJAX, an
example of how to do this would be extremely helpful. Example silly
questions: does my field have to be in a Zone? Or aren't Zones relevant
seeing as I would be making the AJAX get in my own Javascript. Also,
would the % value updated by my process just be held in a @Persist
field?

 

Anyway - some pointers or hints would be greatly appreciated.

 

Regards,

c.

Tapestry Mailing List vs Forum

[Newham, Cameron]

An interesting discussion.

However, while I do see that a forum would, perhaps, be initially more user 
friendly for new people to join, in the end the creation of such a thing would 
either divide the community into those on the ML and those on the forum, or at 
worst the forum would end up with new users joining and no answers because all 
of the old hands are on this ML. It wouldn't look good either way.

Personally I prefer the ML for Tapestry - mainly because the signal to noise 
ratio is high, there aren't huge numbers of posts, and the things drop into my 
mailbox where I can easily see them. People on here are (for the most part) 
friendly and very helpful. I'd rather that wasn't damaged by changing things 
just for the sake of change.

I'd rather that the effort going into this discussion was instead directed to 
providing better documentation. It's one thing I find most frustrating in the 
computer industry. I'm afraid I'm not as geeky as some who reside on here and 
elsewhere; I like instructions to have all the parts filled in, rather than 
instructions where large parts are missing and only the "juicy details" given 
because the author assumes you understand and can fill in background yourself. 
Some of the HOW-TOs are unfortunately like that. I have a job to do and I don't 
spend my weekends building my own server or bed time reading of IPv6 (anything 
but computers! You know what I mean) so better documentation (along the lines 
of the new Tutorial and docs) is better for me, better for my employer, and 
better for those coming to Tapestry for the first time.

Paul, if the user base increased to such an extent that there were scores of 
emails per day then I think we should look again at a forum. Until then I think 
it's not worth exploring.

"I don't see why those questions can't be asked and answered on the

you are missing the point. they probably haven't been asked on the ml 
because the user doesn't want to register/subscribe/manage the ml. some 
people have a general aversion to ml's.

 that's not to say a forum wouldn't work if setup and supported by

Easy:

Create a mixin that:

the
button
- hooks a javascript handler to the button that cancels future submits.
- on AJAX return, revert 2 previous actions from a javascript listener.

RE: Tapestry Web Site Updated

[Newham, Cameron]

I think the new site is an excellent start. I agree with Javier's comments and 
would like to add that the red stop signs in the tutorial are a worry. For 
instance, the first one:

"This chapter may look long, but almost all of it is one-time setup for Maven 
and Eclipse. The actual Tapestry part is really small and simple. Enjoy!"

It looks like there is a problem with the page, along the lines of Wikipedia's 
article warnings made by those editing the text, and with a cursory glance 
looks more like: "This article is too long and needs cleaning up". i.e.: an 
instruction aimed at the authors rather than the reader. It's also rather 
disconcerting, in this example, that the word "enjoy" appears in a big scary 
warning!

There is also a problem with verbosity. I think it's great to have lengthy 
discussions, but possibly place some of the non-directly-related material and 
asides in separate boxes titled something like "Additional Information".

Subject: Re: Tapestry Web Site Updated

I haven't explored the site thoroughly, but here are some comments:

- in general, the new site looks prettier

- it doesn't look good to have a "Tapestry 5.2.3 -- canceled" post on 
the front page. It's scary and you have to read the rest to know that 
it's just a release that didn't pass the vote. I know there's now a post 
above that saying 5.2.4 beta release, I'm commenting about the concept 
of "fear-about-the-future-of-tapestry" content with such visibility. Do 
we want things like that to see what potential new users get on their 
first visit?

- news feed titles have too large a font

- there's too much text in the left column. I know there are a lot of 
benefits and features to tapestry, but it looks intimidating.

- in the "create your first tapestry project" tutorial, don't make the 
user choose an archetype or a tapestry version. Write the instructions 
for the latest stable version. It's better to have that be out of date 
when a new version comes out (because it still will work) than have the 
user decide at this stage. Same for the groupId, artifactId, version and 
package. It's a test project the user is creating, those values are not 
going to matter. Give the defaults so people can copy and paste the 
command and have the project created, built and run.

- the big red scary warning about the project layout changing across 
different versions has no reason to be. By the time the user has this 
problem he will know how to solve it.

- after the test project has been created, give the user some pointers 
on where to find things (pages go in src/main/java/com/example/pages, 
page templates go in webapp). I know there is a link to the tutorial but 
if this first experience is too frustrating, people might not even 
bother to go there.

- add something to the archetype with commented out code that the user 
can uncomment and see something cool happen. It has to be a few lines 
only, to be easily understandable, and clearly link components in the 
template with their methods in the page class.

- the tapestry tutorial starts unnecessarily verbose about topics not 
really related to me getting code running and out the door. Strip it to 
the essentials. If you want to mention Struts and the Servlet API 
compared to the tapestry way, mention them in a separate chapter so they 
are easy to find / skip as needed.

- there is no table of contents for the tutorial and no indication of 
how long it takes to complete.

- there are too many callouts, warnings and decorations in the tutorial. 
It is very distracting visually and that makes it hard to follow. It's 
impossible to scan the pages to get a feel for what you've got ahead of you.

Basically, what most of the above boils down to is: make the barrier to 
entry as absolutely low as possible. All the magic tapestry does for you 
and how great a framework it is will not matter if people don't get past 
the initial experience.

Lots of Tapestry problems - quickstart and tutorial

[Newham, Cameron]

Hi,

 

I've been away from Tapestry for quite a while and haven't done any
serious Tapestry stuff for at least 9 months. I have come back to find
everything broken and I feel like a complete newbie . Could
someone set me straight.

 

Problem 1 (which I have solved) is that I found Maven refused, when
using the "Quickstart Archetype", to download
http://tapestry.formos.com/maven-snapshot-repository/archetype-catalog.x
ml  giving "connection refused" even though it had no trouble
downloading everything else and I could access this file via my browser.
I am behind a corporate firewall, so there seems to be an issue here
with this Tapestry repository location (I had no problems when I
attempted this at home). I spent two days on this and eventually got the
Maven source and modified LightweightWagon and hardcoded our proxy
server. Probably not the right thing to do but it worked - perhaps
someone can suggest what should be done (I tried everything including
various things in my settings.xml, the global settings.xml and even went
as far as using cntlm, although that was not necessary and didn't solve
it anyway).

 

Problem 2 - http://tapestry.apache.org/tapestry5.1/tutorial1/first.html
is out of date and doesn't work. As I'm sure you are aware "create" is
deprecated. When it's changed to "generate" it does d/l a lot of stuff
but the build fails (it throws an exception inside Maven).

 

Problem 3 - Having failed on (2) I tried the "Quickstart Archtype"
http://tapestry.apache.org/tapestry5.1/quickstart/  .  Great - it does
work and mvn jetty:run works. However, when I create a new Project and
place the code into Eclipse it does not work. I can't import it as it's
not an Eclipse Project. Jetty runs when the project is run in Eclipse
but the Index page in the browser just has "[[missing key: greeting]]"
and nothing else.

 

 

To add to this tale of woe, my last big Tapestry project no longer
works. I fire it up and now get Jetty giving me a 503 code, yet it was
working fine a year ago.

 

Anyway, I would just like a nice clean simple example that works in
Eclipse so I can begin coding a new webapp.

 

I am at my wits end... :-(

 

 

RE: About T5 integration modules

[Newham, Cameron]

Interesting.

I'd hardly call myself even an advanced-intermediate Tapestry user (some
of the stuff you guys talk about is way over my head!) but really, is it
that difficult to create a Dispatcher and custom page annotations?!

I included simple security with roles very early on in my webapp by
going the page annotation route because it was a) understandable  and b)
simple to implement by following the examples I'd seen. I had even less
of an understanding of Tapestry than I do now.

I found it very easy to understand and code, and it works so well. I
shudder to think how long it would have taken ploughing through
documents on security solutions, like Spring Security, when all I wanted
was half a dozen roles and some way to mark my pages as general viewing
or requiring login under a certain role.

As I've said all along, I think the only thing lacking big time for
Tapestry is clear, easy to understand documentation with good simple
examples of each feature. That said - I had no troubles with the above
security stuff (and I didn't even have to look at Tapestry source code
;-)

Rather than providing large cumbersome bolt-ons for features that may
not even solve all problems, I'd rather see well-defined methods and
example solutions for particular problems which allows scope for people
to customise if they so wish. Isn't that an example of "convention over
configuration"? ;-) It would also be far quicker than developing modules
that try to be all things to all people - and perhaps lessen the
perceived gap between tech. like Wicket and Tapestry in a much shorter
time period.

Howard, I think people are looking for these kind of integrations
because there is no tapestry module allowing them to secure there
pages. Of course you may argument that it is easy to build a
Dispatcher and define some custom annotations. That's true if you
managed to understand how these things work. But if you've just
started with tapestry, in my experience this is not that easy. Then
you remember about Spring Security or any other solution you are used
to and try to make use of it in your new tapestry-world.

Subject: [ADV] Upcoming Tapestry Training: London, Paris

I'll be doing two trainings with SkillsMatter
(http://skillsmatter.com) in London (Feb 10 2010) and in Paris (Feb 15
2010).  This is my standard three day Tapestry course, as described on
my web page (http://howardlewisship.com/training.html) delivered at a
much better price than I can normally offer ... especially if you act
fast enough to get the 2-for-1 training in London!
http://skillsmatter.com/course-details/java-jee/tapestry-web-development

I teach Tapestry as a hands-on workshop, oriented towards Tapestry
(and Java web development) newbies. The class has a proven track
record for getting people up-to speed in Tapestry 5 quickly.

This represents one of my many long-term goals for Tapestry: to offer
public enrollment training and grow the size of the T5 community. If
you are in the London or Paris areas, this is a great chance to learn
Tapestry from the source.

RE: Discussion

[Newham, Cameron]

I don't agree with the OP that the ServerSide discussion shows Tapestry "has 
lost the battle" - two posters state they don't want to see Tapestry mentioned. 
That's all there is.

However, I can't agree with you Thiago. The old saying is "if you say it enough 
times then people will believe it is true".

If you are just going to stand by and let "trolls" post bad things about 
Tapestry unchallenged then they have won the argument - regardless of how bad 
their argument may be and how incorrect their views may be.

After all, someone pitching up and wanting a framework will read what they've 
written and believe it. Who is to say these anti-Tapestry people are wrong?  
Not you - because you won't counter their arguments! :-)

Sure - don't feed the trolls. But all that is necessary is to say something 
positive; not engage them in an argument.

Merry Xmas everyone.

Subject: [Tapestry Central] Next Steps for Tapestry

I've been consciously letting Tapestry 5.1 sit and stabilize for a
while ... a time that's stretched a few months longer than I initially
intended.
This is due to a number of factors: my return to independent
consulting, my desire to write a definitive Tapestry 5 book, and
preparations for many trips and speaking engagements.
All of these factors have worked on each other: I've been improving and
extending my Tapestry Workshop training materials which can be quite
time consuming. I've also (over the last several months) been on the
road several times, talking about Tapestry or doing Tapestry training.
I do want to write a book on Tapestry but if I start writing 5.2 code,
I know I'll be sucked right in ... lots of code (that darn Spring Web
Flow integration for sure this time) and bug fixes.
In addition, I've had an embarassment of riches: two main clients, one
regular part time, and the other requesting (but not always getting)
all my remaining time. I also have additional clients and training
engagements waiting in the wings. I simply have a lot of draws on my
time.
As usual, working on real-world projects lets me experience the "rough
edges" of Tapestry and fills me with ideas on how to address those in
the next release ... often by splitting up Tapestry services into
smaller, more easily overridden chunks and carefully moving internal
services out into the public APIs.
Finally, I've been very pleased by the fact that as I've stepped back
temporarily from my normal stream of commits, the other Tapestry
developers have stepped in and filled the gap. There's been quite a bit
of activity especially from Igor that I've barely had a chance to keep
up on.
So the question is: do I wait and see if time opens up in Q1 to
actually start on a T5 book ... or do I jump into 5.2 coding and leave
books to others? It's much, much easier to write code than to write a
book ... a book is a large amount of concentrated effort. It's very
hard to accomplish anything on a book using an hour here or an evening
there ... whereas Tapestry's code base lends itself to that kind of
effort quite nicely.

Something I've never done because it's not logical to have errors in "success".

BTW, I believe you mean onValidateForm().  onValidate() is called before values 
are set and they can't be tested correctly.

T5: query about onValidateForm()

[Newham, Cameron]

Apologies if this is obvious, but I'm getting confused over how and
where onValidateForm() should be used. I have a page with search fields
in a form and also a grid for the results.

 

Currently I have:

 

  public void onValidateForm()

  {

if (title == null && issn == null)

{

  searchHoldingsForm.recordError("Please provide a value
for Title or ISSN");

}

  }

 

  public void onSubmitFromSearchHoldingsForm()

  {

// perform database access using the form fields...

...

 

 

However, the onSubmit...() will be called even if there is an error. Ok,
I could use a Boolean and set it in onValidate() and then bail out in
onSubmit...() if there is an error. Or I suppose I could dispense with
onValidateForm() altogether and set the error messages directly in
onSubmit...()  Or perhaps I should keep onValidateForm() and do the DB
stuff in onSuccess()?

 

What is the correct way to proceed and why?

When I had trouble with javassist a few months ago it was because there

Also make 100% sure that there aren't multiple javassists (different

right
one. Check this from the produced war, do NOT trust what the ide is

Sometimes we have had problems like this, but those were because maven
dependencies affected to the included javassist version.

We use java 6, and our compile targets are 1.6 in about ten projects, we
have multiple developers compiling with different versions of java and
haven't had any problems besides those javaassist version related.

The version of javassist that gets included for us is 3.9.0.GA

Hello

Have a look at http://tapestry.apache.org/tapestry5.1/guide/pagenav.html

If you want to use 'activate' you have also to define the pending
'passivate' method.

Using a validator would be ok, but unfortunately that assumes that the
component being validated exists in isolation. In my case I only want to
do the validation depending on parameters that have been set by other
components on the page, viz:

public void onValidateForm()

if ((tagSelectionId == -1) && (nsTagSelectionId == -1)

{
if (keywordVisual.getKeyword().getValue() ==
null)
{
tagForm.recordError(keywordField,
"Please provide a value");
}
}
}

As far as I can see page properties are not available in a validator and
there is no way to pass these to a validator.

Is there any way I can access the components on a page indirectly?
(i.e.: so I don't have to specify them with @Component). Then I could
iterate over the textfields in my grid and provide tagForm.recordError()
with the correct components to mark.

It seems odd to me that the facility onValidateForm() is provided for
doing validation of the entire form and yet access to the components in
that form, which may have been dynamically created in a Grid, does not
seem possible unless they have been statically created. Maybe I'm not

That's why using the TextField's validate parameter is recommended. It  
will put the error markers in the right places. If your needed
validation  
doesn't use other properties than the one edited by the TextField,  
implement your own Validator and use it. You also get an improved  
reusability. :)

RE: Validation on textfields in a grid?

[Newham, Cameron]

Thanks again Thiago.

Yes, my fault for not saying exactly what I wanted to achieve.

I agree that one can iterate over the values in the source and check
them, but I need to mark the field/fields which fail validation on the
form with:

tagForm.recordError(keywordField, "Please provide a value");

So how do I get the correct keywordField object as any number of them
are created in the Grid, depending on how many rows there are, and the
names are generated by Tapestry, as is the connection from the field in
the form to the TextField Component object in my code.

An easy way out would be just to have a single error line, but from a UI
perspective it would be much nicer to have the big red X next to the
actual field that fails, not to mention being consistent with the rest
of the application and how errors in forms are displayed.

I just remembered that Grids inside Forms typically only work when you
use  
the row parameter.

Well, this information changes the solution. :)
In the validateForm event, you need to validate all the objects in the  
Grid, not just one, so you need to iterate over the collection used as
the  
Grid source. The event is not repeated for every element, being fired
just  
once.

RE: Validation on textfields in a grid?

[Newham, Cameron]

Hi Thiago,

Thank you, but I'm not quite clear on what you mean.

The row parameter is only accessing my data from the source parameter,
not the components themselves.

Also, I am not clear about validation through the validate parameter -
is there an example of this I can look at? However, I have to do the
validation myself; I simplified the code posted and actually need to do
some other things besides checking for null from the text field.

Try accessing the Grid elements using the row parameter and use the  
validation done by the validate parameter instead of doing it yourself.

Validation on textfields in a grid?

[Newham, Cameron]

I could have sworn I had this working at one point, but now it doesn't.

 

Tml:

 



 

...

 







 

...

 

 

The Java:

 

...

 

@Component

private TextField keywordField;

 

...

 

 

public void onValidateForm()

{

if (keywordVisual.getKeyword().getValue() == null)

{

tagForm.recordError(keywordField, "Please
provide a value");

}

}

 

...

 

 

 

The validation is only occurring on the last field in the table - I
presume that is because keywordField is being set to the last value,
which is fair enough. In that case, how can I perform validation and
give error messages on the other keywordFields? I can't find an example
of this on JumpStart or in the docs (or maybe the example is there but I
just haven't seen it).

The order of events seems to be now:

onValidate()

onValidateForm()
onSuccess()/onFailure()
onSubmit

I didn't find a summary in the docs on the exact order, and on the
default 
event method names (that incorporate the form id).
Also, I don't know what happens if there is, for example, a onSubmit(), 
onSubmitFromXXX() and a method annotated with @OnEvent(value="submit", 
component="XXX")
in the page.

So, in short, try using onValidateForm() instead of onValidate().

It does use the latest Javassist version:

Thanks Peter.

I do use ChenilleKit but haven't run into this problem (I presume that's
because Maven always uses the later version if there is a conflict? And
as I've explicitly brought in the later version of Javassist then that
overrides any earlier versions being included on the classpath)

I do notice that ChenilleKit wants to use Tapestry 5.0.18 and is causing
a conflict there. Is this likely to be updated soon?

T5.1.0.5: StackMapTable format error

[Newham, Cameron]

Hi,

 

I'm still trying to move to 5.1.0.5 but have had to fight quite a few
fires. I've finally wrestled it into getting my app up, but have now hit
a brick wall.

 

My Index page comes up fine when running my app from Jetty in Eclipse.
However, as soon as I attempt to log in and Tapestry tries to go to the
app "home" page I get a StackMapTable format error.

 

Can anyone tell me what this is or what might cause it. The only example
I can find on searching the list archive was someone who had their page
incorrectly named - that isn't the case here as my app was working fine
under 5.0.18.

 

I should point out that I've done a clean and a new build for my
project.

RE: t5: moving to 5.1.0.5 and can't find @Inject

[Newham, Cameron]

Thanks Kris, it would be nice if it did!

I already have tapestry-hibernate-5.1.0.5.  No tapestry-hibernate-core
though.

Maven is such a heap of ***


Again, it would be nice if the classes and their whereabouts were
actually documented. It seems to be such a lapse not to do so - not to
mention a lot of pain having to ask on here!

Thanks Kristian. I had to manually add it to my POM - that did the
trick.

However, sorry to be a pest everyone, but I cannot now find:

org.apache.tapestry5.hibernate.annotations.CommitAfter

This is in the 5.0.18 version of the tapestry-hibernate jar but not in
the 5.1.0.5 version.

Is there anywhere I can find out exactly what things have been moved
between jars and what re-ordering has taken place? I can't find anything
on the Tapestry 5 website that is relevant. Surely this should be
documented in release notes?

Also, is there anywhere I can find a list of classes and what jars they
are in. There doesn't appear to be any way to find this out on-line.

This looks like some other package you're using depends on Tapestry-IoC

5.0.18. If you're using Eclipse, install the Sonatype's m2eclipse
plugin. 
In its Maven pom.xml editor, it has a very nice feature that shows what

dependencies are being included and by which dependency (transitive 
dependency).

[Newham, Cameron]

Thanks Otho, but I'm still having no luck.

Ok, I haven't been keeping up with events and didn't know 5 was the
latest, so now I have 5.1.0.5, but...

If I don't include:


org.apache.tapestry
tapestry-ioc
${tapestry-release-version}


In the POM I get 5.1.0.5 for all jars *except* tapestry-ioc which always
downloads the 5.0.18 version  /:-(

(I don't understand why the dependency does that)

And if I add the above lines I get 5.1.0.5 but tapestry-ioc-5.1.0.5.jar
does not contain @Inject.

I'm even more confused now than when I started...

Why don't you update to the official final version 5.1.0.5?

@Inject is in org.apache.tapestry5.ioc.annotations definitely but in the
maven artifact tapestry5-annotations which should be automatically
included
from tapestry5-core

RE: Multiple submit button and client validations

[Newham, Cameron]

I had a dropdown box that in turn changed another field but this
wouldn't work if the user left a text field blank. As I only needed the
validation to occur when they did the final submit for the page, I used
Javascript to perform the submit from the drop-down which gets around
the client-side validation.

Perhaps the solution to your problem lies in that direction?

Hi all.
I have a form with two grid components inside.

i fill every grid with data input from several textfields, using its own

submit button.


Name Surname 
[ GRID ]

CarPlate CarName 
[ GRID ]


Every field has required validation constraints, and this is the
problem.

When i hit whichever 'addXX' button, i insert those fields inside the 
grid, BUT the client validation for the other textfields do not allow me

to insert it.

Is there another solution than to split this page into 2 pages ?

t5: moving to 5.1.0.4 and can't find @Inject

[Newham, Cameron]

I think I'm going mad...

 

I'm moving from 5.0.18 to 5.1.0.4 and after doing a dependency update
with Maven, Eclipse gives me errors saying it can't find

 

org.apache.tapestry5.ioc.annotations.Inject

 

Looking in tapestry-ioc-5.1.0.4.jar it isn't there, but looking in the
5.0.18 jar I can't see it there either - so which jar does it normally
live in?

 

Maven seems to have correctly downloaded all the 5.1.0.4 jars and I
don't have any old Tapestry jars on the build path.

RE: [Tapestry Central] Why chose Tapestry?

[Newham, Cameron]

I have found Maven is great for starting a T5 project, but if you aren't
careful later on then it can become a nightmarish hell.

Having to remove and rebuild the repository a tool has created because
it has gone and messed it up doth not a good tool make.

RE: best book for T5

I wonder how many people would be interested in the German version
compared to an English version.

Are there many German Tapestry developers? Perhaps it would be
interesting to know the geographic spread of developers using this
framework.

I assume the publishers have done their homework and know there will be
a big enough audience for the book to make money.

That's the way I've written the access control on our system.

Subject: Re: Authentification in Tapestry

We are using a custom dispatcher called "AccessControlDispatcher".
It is like the AccessDispatcher described in the howto-wiki, but in
addition
it checks for certain roles.

This works through a SessionState object that implements an interface
used
by the dispatcher to determine if the SessionState object has the 
required role(s)
or not.

All you have to do is to annotate the desired page with 
"@Secured(Role.ADMIN)"
for example. the dispatcher checks if the current user has the required 
role for this page,
if not the dispatcher calls an AccessDeniedCallback, where you can 
redirect to the login page
or something like that. The Callback and the Class of the SessionState 
object that implements
the interface needed by the dispatcher are contributable over a mapped 
configuration.

It is very simple and i think there is a lot potential to improve this,
but
until now it works for us.

Maybe this idea helps you ^.^

RE: T5: What is NOT beautiful about Tapestry?

[Newham, Cameron]

3) Documentation - Good solid reference examples of how to do do simple
apps, explained in detail. Most developers want a framework to be like
lego
building blocks. I do A, B, C and D and I get E. I assemble a dozen
different pieces and I have my app. Really how complicated are most web
apps? They are forms and workflow and validation.  To get developers to
use
your framework you need good examples of how to do each, laid out and
described in simple guaranteed to work steps. There need to be examples
of
these  in both Netbeans and Eclipse; preferably several examples of
each.

---

All good points, but this above all others I think. Developers never
seem to fully appreciate this - or if they do, they make it a lesser
priority.

Documentation is critical. It doesn't matter how good something is (and
that those "in the know" know it), it's rendered useless if the
documentation doesn't exist or is not up to scratch. Tapestry 5
documentation is not up to scratch. I'll repeat that: Tapestry 5
documentation is not up to scratch.

Why?

Unfortunately there are a plethora of places to look in if you want to
find how to do something. It's not only annoying for people who are
developing in Tapestry, it is off-putting to new developers who are
looking at this as a possible solution to a development problem.

We've now reached a stage in web development where things should be easy
to put together (Lego building blocks). I used to hate web development
and Tapestry 3 was the first thing I found which helped me dislike it a
lot less. Tapestry 5 even more so. However, having no good set of
central documentation, how-tos, cookbook solutions, etc makes the
development process that much harder and not like Lego blocks. I really
only want to have to think about business logic and know only the basics
of how Tapestry works. Turning to the source code should be a last
resort and I've had to do that once so far with Tapestry 5 because the
documentation I required was inadequate (can't remember what it was now,
but it wasn't even anything exotic I was trying to do!)

That said, I think this mailing list is fantastic and has certainly
ridden to my rescue on numerous occasions. The only off-putting thing is
the fear of asking the "dumb question". Sure, no questions are dumb, but
I always feel a lot better if I know I've made an effort to find out how
to do something before asking on here. Again, lack of good docs makes
that effort so much harder and also increases the traffic on here by the
same questions being asked multiple times.

I think we are all in agreement that the documentation needs a radical overhaul

The next question is, who is going to do it?

A while ago someone proposed a book on T5. A small group from here organised a

Hi,

also a guide/recipes/good practices/tips/chapter for converting JSP
applications to Tapestry 5 would be very welcome. At least a paragraph
clarifying questions like: "Can I have JSPs in my Tapestry 5 application or
do I have to have two web applications talking somehow to each other?", "How
to post a form from JSP to a Tapestry page or vice versa?", ...

A guide on clustering. I know this info can be found in many locations on
the net, but writing it in Tapestry documentation would imho greatly improve
the credibility of the framework for "serious" web applications. I feel
tapestry is missing the scope in the market. It is not advertised in any
way, nor as a framework which one can use to quickly make a simple news
site, as other frameworks (non java) are better at that (so I hear), nor as
a framework which is best for large teams and large applications. Just look
at the web page for Zend PHP framework (http://www.zend.com). Which page do
you think management like more, zend's or tapestry's? Unfortunately
sometimes (too often) the arguments of power outweight the power of
arguments and the consequence is, well, "We will use the framework which has
more flashy homepage!".

The community, us, must prove that a simple web application (some forms,
administration pages, publishing news, social "crap", etc) can be done
without having a PhD in Computer Science. Tapestry relies much on convention
over configuration paradigm, that is why the documentation must be excelent.
Say, for example
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Form.html.
This page is clearly frightening - look at the first paragraph. So many
events and none/few of them has a decent explanation/usage scenario/example.
IMO all of them should be properly documented or not mentioned at all.

The authorization should have a chapter! Tapestry is a very powerful
framework and as such the same thing can be done differently, BUT...why
should one have to spend days/weeks to implement a decent
authentication/authorization system? There should be a guide for common
scenarios like form based authentication. Of course one can hunt for example
projects and study the guts of them, which in the end is very rewarding, but
time consuming. Newcomers should have clear goals on how to implement such
things, without jumping to the wiki and other places and fighting the
dependency incompatibilities.

I second this.

I much prefer the "cookbook" approach as opposed to having to wade through a 
complete application to find how to do something.

Jumpstart is excellent and has helped me many times. All it needs is perhaps a 
bit more explanation of what's going on, more cases covering solutions to 
common problems, and a bit more filling out.

**documentation** !!!

I see very little information on the Chenille Kit site - some parts,
like the Scripting page, are just blank.

I'm currently using the t5 Components library and would move to this new
version but without documentation there doesn't seem to be much point.

Subject: [ANN] ChenilleKit Release 1.0.0

Hi all,
  the ChenilleKit team is pleased to announce the availability of the
first release of the ChenilleKit Project.

The 1.0.0 release includes all the features present in the former
project T5Components from which the ChenilleKit is born plus more
features not present there.

Here is a comprehensive list of features available.

 * Core   core utilities we need for some of the following
modules
 * Access   library which provide access restriction constraints
to Tapestry 5 web application
 * Google   Google based services like geocoding, distance, etc
 * Hibernate  some utility classes and services to simplify the life
with Hibernate
 * Hivemind   a bridge from/to Apache's HiveMind to Apache's Tapestry5
 * Imagea simple image scaling service
 * LDAP simple search service against a LDAP server
 * Lucene  indexer and searcher service based on Apache's Lucene's
full text engine.
 * Mail   simple mail service based on Apache's Commons Email
 * Quartz  Quartz based scheduler services
 * Reports  Jasperreports based reporting services
 * Scripting   scripting service based on Apache's Bean Scripting
Framework
 * Tapestrycollection of components and services for your Apache's
Tapestry5 Framework based applications
 * Template   Apache's Velocity and FreeMarker based template services

Every feature is available as a separate module (Tapestry5 library).

If you use maven as a build project system you can access these
libraries using our repository.
In your pom.xml file specify the ChenilleKit repository:


chenillekit
http://www.chenillekit.org/mvnrepo/release

false



Then you are able to set dependency on ChenilleKit libraries the usual
way:


org.chenillekit
chenillekit-quartz
1.0.0


If you're not using maven you can download the libraries from the
project page:

http://code.google.com/p/chenillekit/

Project and documentation site is available at:

http://www.chenillekit.org

This 1.0.0 release is considered beta and the ChenilleKit is following
the Apache convention (the same as Tapestry5 project is doing) for
software release so following releases will be voted to gain final/GA
status release for 1.0 branch.

The current trunk (HEAD) will follow Tapestry 5.1 while we have
created branches/1.0 to succeeding 1.0.x releases which will be based
on Tapestry 5.0 branch releases.

Feedback is always welcome.

The ChenilleKit team would like to thank Sven Homburg for providing
the box and Internet connectivity fro ChenilleKit.org domain and last
but not least the original code of T5Components.

Happy new year to everyone!

RE: T5: The other misleading term is "encoder"?

[Newham, Cameron]

I agree - I found it confusing when I first read about it. It isn't an
"encoder" as it also "decodes".

Much prefer your term "mapper".

Subject: T5: The other misleading term is "encoder"?

Has anyone else found the "encoder" concept in Loop misleading?  I'd  
suggest renaming it to "mapper".

I see a "mapper" as being something that maps between one thing and  
another, eg. between a key and an object.
An "encoder" is something that converts data between formats without  
loss - all the data is there and only its format has changed (eg. from  
chars to binhex).

In fact, the Loop component actually uses both - it asks our "mapper"  
to give it the key of the data, then it uses its own internal  
"encoder" to encode the keys into a hidden field. On submit, its  
internal "encoder" decodes the hidden field, then gives the keys to  
our "mapper" which has to return the corresponding object, possibly by  
going to the database.

I raise this thought because I found the name "encoder" blurred my  
understanding of what I really had to provide and how it would affect  
what went to the client.  I'd suggest "encoder" becomes "mapper", and  
(even more controversial?) PrimaryKeyEncoder becomes PrimaryKeyMapper.

Has anyone else found confusion in this?

I really would love to see a walkthrough on making blog application in
tapestry5+spring+hibernate. Not only the integration, but how to implement
simple blog with it, design DAOs, where to put them etc. Tapestry alone is
no use if you do not have DB. In advanced topics I would like to see ex.
acegi integration, more ajax complex examples, own components etc. I find
examples very useful and most of people learn by examples very well.
That is my suggestion.

Typo on my part. I meant Run Jetty Run:

http://code.google.com/p/run-jetty-run/

which is an Eclipse plugin.

I had seen that one too but I'm afraid that, while I understand the
underlying problem, the wiki entry solution doesn't mean a great deal to
me as I am have not been using Maven for very long and don't know much
about POMs or artifacts.

I don't see why I should have to have a "run class". Surely it should

as I initially tried).

Hi,
I asked about this a few weeks back and Ben Gidley pointed me at the
wiki with these words

" What is happening is Jetty hides 'server' classes from the web
application unless they are also in WEB-INF/lib. When you run in the IDE
you don't have a WEB-INF/lib so it can't find the slf4j classes as they
are loaded by Jetty as server classes.

You are starting Tapestry inside your IDE using a Run class - you need
to add a line into your startup class saying

 // Remove slf4j from list of classes not exposed to webapp
webapp.setServerClasses(new String[]
{"-org.mortbay.jetty.plus.jaas.", "org.mortbay.jetty."});
