Re: Tapestry 5.0.12
Hi Howard! Don't forget to release Tapestry 5.0.12 together with a useful demo application once the time is ripe. The more demos, the bettermaybe even a Petshop 2.0 with Ajax widgets? So long Tobias Original-Nachricht Datum: Tue, 22 Apr 2008 20:20:49 -0700 Von: Howard Lewis Ship [EMAIL PROTECTED] An: Tapestry users users@tapestry.apache.org Betreff: Tapestry 5.0.12 People have been leaving messages on my blog that they want Tapestry 5.0.12. I don't think it's time yet. I'm using T5 for a client project with a fair amount of DHTML (fancy hiding and revealing menus) and a chunk of Ajax. This is giving me a chance to nail down some limitations and omissions, and tackle some nasty InternetExplorer-is-brain-dead issues. Given how easy it is to get a nightly build, or build locally, I don't think there's that much advantage to cranking out an official release -- a process that requires several days to vote, and an hour or two of my time to perform the builds and uploads. A new feature about to roll out is a client-side JavaScript console which will make debugging (especially on IE) a lot easier. I've also been developing for my app an AjaxFormLoop, a way of combining Loop, FormInjector and a few other bits and pieces to allow dynamic addition and removal of items from a list; basically, the kind of thing you do for master/detail relationships. Anyway, please be patient or use the nightlies. Tapestry 5 is getting very close to a next release (which I think may even be a release candidate), but that's no reason to ship it early.

Is it possible to prevent the render method in parent component from being invoked?
Hi, First I know it is a feature that parent method is prior to child's. I need to extend GridPager component because the action link in GridPager doesn't have a context parameter, so the context info of the link is very limited(only the page No.). And I don't like to persist context in session. The case is that in a user list page with search function and Grid component, user input keyword username, role and so on, and then click 'search' button, the relevant result will be shown in a Grid's page 1, but when user clicks page 2, the search keyword is missing, then the result is wrong which is not expected. So I extend GridPager to provide context to actionlink, but because it (as parent) implements a method beginRender() which is always invoked by Tapestry5 ahead of my GridPager's beginRender(), so now there would be two pager generated in list page. So is there a way to prevent the render method in parent from being invoked? And how? And what's the best practice here dealing with search funcion with Grid? Anyone please share your experience.

[T5]: javax.mail from Tapestry
Hello, In my dev environment (running jetty6 from inside Eclipse), I'm able to use javax.mail classes and successfully connect to my mail server to send a message. But when I migrate the code to my production server (jetty6 also), everything seems to work correctly except that the app doesn't connect to the outbound mail server. I've watched the packets (tcpdump), so I know that the webserver isn't even trying to connect to the mail server. There are no errors mentioned in the log. In fact, I can only get startup/shutdown messages and Hibernate messages written to the log, for some reason I can't seem to control what's being logged in production (although I can in dev). The logging is not my major issue...I don't care about that as long as I get mail working (I'll go back and fix logging later). Can someone help me with javax.mail? Here is the relevant line from my pom.xml: dependency groupIdjavax.mail/groupId artifactIdmail/artifactId version1.4.1/version /dependency Help?

Re: [T5]: javax.mail from Tapestry
Sounds like an issue with the server configuration, I suggest you get the logs to work first, then you might get a better idea of why the mail isn't working... if it works in development then chances are you are missing a host entry or something small like that, which will pop up in the logs.

RE: T5: Forms - Best Practice
Jim,
I have a T4 application that uses domain-object level security implemented
using the Acegi framework. I have used custom authorization code more
appropriate for my task, rather than the built-in Acegi method.
It works beautifully, and I've certainly seen people attempting to access
things they shouldn't.

Subject: Re: T5: Forms - Best Practice
Hi Christoph,
I know you're mostly asking about best-practice of process rather than
security, but I think it's nonetheless important to bring up the issues
that can arise when embedding primary keys of your entities client-side.
I'm still a T4 user, but when you say a PageLink on a PersonSearch
page, which has the Person's primary id as context, I assume that's
analogous to the parameters attribute on a DirectLink in T4, in that
the parameter is embedded in the page. Even if that's not the case,
I'll continue anyway :P
Building on your example, let's say that the logged-in user should only
be able to search/edit people within his/her department. If we're only
passing the PersonID to the PersonEdit page, and that ID is embedded in
each rendered link on the PersonSearch page output, then the user could
hack the form/link from the PersonSearch page to pass an arbitrary
PersonID to PersonEdit, potentially giving the user the ability to
perform unauthorized edits.
I've started taking the approach of embedding not the ID, but a piece of
information that's unique within the security-context (by
security-context, in this case I mean department). In this case,
assuming that a person's full name is unique within a department, we
could embed the person's full name into the PageLink, and the PersonEdit
page would search not on the primary key of the person, but instead on
the combination of the DepartmentID (retrieved from the session if we're
keeping a User object in the session) and the full name we passed in.
Since we're using the DepartmentID from the session, then the user can
hack the form/link all he/she wants, and the best they'll do is bring up
the editing form for someone that wasn't in the search results but is
still in their department, so it'd still be an authorized action.
This sort of approach is annoying, because we'd love to be cleanly using
solid efficient primary keys, but it probably pays to be paranoid.
Anyone have a better approach on this issue? Particularly with regard
to search pages?

Hi,
Sorry for this long post. I spent quite some time now to try to figure
out how to use forms to edit/update objects the right way (you know,
simple, stable, elegant, easy to read, easy add things, ...). I use
Tapestry 5.0.11. I am almost satisfied with what I came up with now,
but some improvements need to be done. Maybe someone on this list can
help with some ideas.
As an example, lets have a PersonEdit page, with a PersonDao injected.
You can create new Person entries or edit existing ones. To edit an
existing person, there is a PageLink on a PersonSearch page, which has
the Person's primary id as context. To create a new Person, a PageLink
with 0 as context is used. To make this work, we have onActivate() and
onPassivate() methods in PersonEdit:
void onActivate(int id)
{
_id = id;
if (id == 0)
{
_person = new Person();
}
else
{
_person=personDao.get(id);
}
}
int onPassivate()
{
return _id;
}
This way we can avoid using @Persist on the Person property (because,
for instance, we want a user to be able to open two browser windows,
viewing two different Person entries side by side and edit and save
both of them. I think this would be problematic if we use @Persist,
but please correct me if I am wrong).
Now, editing an existing user works like this:
- click the edit user XYZ PageLink on the PersonSearch page
- in onActivate(), the personDao is used to query the Person from the
database
- an HTML form is rendered to let the user edit the values
Up to here everything looks perfect.
- the user edits the Person's data and hits the save button
- onActivate() is called, a fresh Person is loaded from the database
- for each field in the HTML form, validation is done (if defined),
and a property in the fresh Person instance is set if the validation
was successful
- onValidateForm() is called if existing to allow for cross-field
validation
- if all validations were successful, onSuccess() is called. Here we
call _person=personDao.save(_person). This save method returns a new
Person instance, exactly as it was written to the database (primary id
may be generated by the database, time stamps or version numbers
updated, ...). We use this new Person's id : _id=_person.getId() to
make sure we have the correct if
Problems with Javascript in Tapestry 4.1.5
Hi all,
We moved from tapestry 4.0.2 to 4.1.5
we were using a script file and in had used the
initialization/initialization tag to initialize the values used in
script functions.
The variables defined in this tag were working as global variable and we
used to get the value of these variables in any script function.
After shifting to 4.1.5 the initialization is treated as a different
function and so the variables defined there are local to it, these variables
loose there values as we try to access them in different script functions.
the code is as follows
initialization
var thArray = new Array();
foreach key=th expression=ths
thArray[t++] = new Th(${th.thId}, ${th.position});
/foreach
swapThArray();
/initialization
function swapThArray() {
var tswap = thArray.length;
for (var k = t; k t + (thArray.length - t - 1)/2; k++) {
var tempth = thArray[--tswap];
thArray[tswap] = thArray[k];
thArray[k] = tempth;
}
}
getting a javascript error in swapThArray that thArray has no properties

My breadcrumb component from T4 to T5
Hi,
Need some advice. In T4 I had a breadcrumb component that got its
information from a breadcrumb model structure. Each page that needed to go
onto the crumb path would implement some base page class. This page class
implemented PageRenderListener and IExternalPage. The former to add info
to the model and the latter to remove info from the model (btw the
breadcrumb model was an ASO).
Basically the model consisted of some key, name/title and (constructed)
link tuple. The link basically pointed to an IExternalPage implemented
page class - so to be precise the whole breadcrumb path consisted of
bookmarkable pages.
I'm trying to mimic this behavior with T5, using the BeginRender
annotation on a basepage class method called initPage() and also on the
basepage class a onActivate() method. I have some questions about it.
Below the specific base page code:
protected String getBreadCrumbTitle() {
return resources.getMessages().get(title- +
resources.getPageName().toLowerCase());
}
protected Object[] getLinkParameters() {
return null;
}
@BeginRender
public void initPage() {
String pageName = resources.getPageName();
Link link = resources.createPageLink(resources.getPageName(),
true, getLinkParameters());
breadCrumbHolder.checkBreadCrumbForAdd(pageName,
getBreadCrumbTitle(), link.toRedirectURI());
}
public void onActivate() {
String pageName = resources.getPageName();
breadCrumbHolder.checkBreadCrumbForRemove(pageName);
}
Q1: the initPage() method is there to create a 'bookmarkable' link -
amongst others - and store that information in the breadcrumb model. The
getLinkParameters() is there for a subclass to provide its specific
activation parameters to be used. Should I use another way to create
bookmarable links?
Q2: the onActivate() method is there to remove one (or more) crumbs from
the crumbpath. Since other pages will also need activation - potentially
with additional arguments - is this onActivate() the best way/place to
manipulate the model? I'm getting the idea that onActivate() is not the
designated alternative for T4's activateExternalPage(Object[] parameters,
IRequestCycle cycle) in IExternalPage interface.
Currently all of this works - although haven't tested activation with
activation context parameters yet.
Thx.

Re: Dynamic list of strings in a form
Thank you very much, that was exactly what I was looking for. I am new
to tapestry and it was not clear for me how loops are working, but now I
understand it. :-)
Also many thanks to the other guys that replied.
@Marcus: Grid didn’t work for me, because I didn't have any Bean that I
could pass.
@Francois: Looks like a nice component and a generic solution for that
kind of problem. But I think it was bit overkill for me.
@Igor: FormInjector may work, if I always start with one input field.
But I also have to provide an edit form where already can be a set of
values. I am not sure how I could implement this using the FormInjector.
Regards,
Michael
Josh Canfield schrieb:
Hey Michael,
I know a couple of guys have replied, but I think there is a much
simpler answer to your problem.
drop the item property from your page and add getter/setters that
update the your items list based on the index in the loop:
@Property
private int _index;
public String getItem() {
if ( items.size() = _index ) {
// what to do when the index is out of bounds?
}
return items.get(_index);
}
public void setItem(String s) {
if ( items.size() = _index ) {
// what to do when the index is out of bounds?
}
items.set(_index, s);
}
and update the loop div in your template to bind the index property:
div t:type=loop t:source=items t:value=item t:index=index
The way your page was written you were telling tapestry to update the
item property for each value in the list, which it dutifully did. But,
what you really wanted was it to put the items into your list.
Hope that helps,
Josh

I have a list of values, the user has to enter. The number of values, that
have to be typed in, is dynamic, so the user has to extend the form.
The add button works, but the values are not saved. Can someone tell me,
that I am doing wrong?

Re: Form with a Zone - ComponentEventException
Maybe because IE
you need edit tapestry.js about linkZone:function...
element.onsubmit = handler; replace to: Event.observe(element, 'submit',
handler);
and element.onclick = handler; replace to:Event.observe(element, 'click',
handler);
and need add line :Event.stop(event);
after new Ajax.Request(element.href, { onSuccess : successHandler });

beginRender will
: create a bookmarkable link
: store (if necessary) in the model of breadcrumbs.
onActivate gets called whenever a breadcrumb - rendered as link is clicked
and will
: remove a crumbs that are listed after the clicked link, cleaning up
the trail
I think the workflow is okay - as it is proven in T4. I'm just looking for
the correct points to hook it into T5.

Re: My breadcrumb component from T4 to T5
Ah, by workflow I meant to ask when you expected the events to get
fired, which you answered for the onactivate handler.
So, why not do this all in one event handler, perhaps setupRender?

I used T4 for a short period a long time ago, so I'm not understanding
the parallels that you are making. Can you describe the workflow that
you are shooting for? I'm not clear why you'd remove the breadcrumb in

beginRender will
: create a bookmarkable link
: store (if necessary) in the model of breadcrumbs.
onActivate gets called whenever a breadcrumb - rendered as link is clicked
and will
: remove a crumbs that are listed after the clicked link, cleaning up
the trail
I think the workflow is okay - as it is proven in T4. I'm just looking for
the correct points to hook it into T5.

Hi,
Need some advice. In T4 I had a breadcrumb component that got its
information from a breadcrumb model structure. Each page that needed to
go
onto the crumb path would implement some base page class. This page
class
implemented PageRenderListener and IExternalPage. The former to add info
to the model and the latter to remove info from the model (btw the
breadcrumb model was an ASO).
Basically the model consisted of some key, name/title and (constructed)
link tuple. The link basically pointed to an IExternalPage implemented
page class - so to be precise the whole breadcrumb path consisted of
bookmarkable pages.
I'm trying to mimic this behavior with T5, using the BeginRender
annotation on a basepage class method called initPage() and also on the
basepage class a onActivate() method. I have some questions about it.
Below the specific base page code:
protected String getBreadCrumbTitle() {
return resources.getMessages().get(title- +
resources.getPageName().toLowerCase());
}
protected Object[] getLinkParameters() {
return null;
}
@BeginRender
public void initPage() {
String pageName = resources.getPageName();
Link link = resources.createPageLink(resources.getPageName(),
true, getLinkParameters());
breadCrumbHolder.checkBreadCrumbForAdd(pageName,
getBreadCrumbTitle(), link.toRedirectURI());
}
public void onActivate() {
String pageName = resources.getPageName();
breadCrumbHolder.checkBreadCrumbForRemove(pageName);
}
Q1: the initPage() method is there to create a 'bookmarkable' link -
amongst others - and store that information in the breadcrumb model. The
getLinkParameters() is there for a subclass to provide its specific
activation parameters to be used. Should I use another way to create
bookmarable links?
Q2: the onActivate() method is there to remove one (or more) crumbs from
the crumbpath. Since other pages will also need activation - potentially
with additional arguments - is this onActivate() the best way/place to
manipulate the model? I'm getting the idea that onActivate() is not the
designated alternative for T4's activateExternalPage(Object[]
parameters,
IRequestCycle cycle) in IExternalPage interface.
Currently all of this works - although haven't tested activation with
activation context parameters yet.
Thx.

Re: T5: Forms - Best Practice
Hi Jim, I like to use the primary key, because it is short and by definition unique, and usually the quickest way to retrieve an object from the database. For the problem you describe, users are only allowed to view people in their own department, three different solutions come to my mind: 1. in onActivate(), where the personDao is queried for the Person with the given id, check if the logged in user may view the requested Person information 2. in the PersonDao itself check for permissions 3. as Jonathan Barker wrote in an email in this thread, use domain- object level security 1 is the quick and dirty way, easy to leave some holes open, but it should work in any environment. 2 only works if personDao (wherever it is executed, might be a remote call on some different server than your web-app) knows about the logged in user, and for 3 you probably have to use some framework like Acegi or some container managed authentication and authorization. But there is a different scenario, where we have to find a different solution: imagine some web-frontend to a database of companies. Everyone can search for companies, but you want to limit the search to show only the top 10 results, so no one can harvest your whole database. Using the primary key here proves to be easily exploitable, just try the result page with ids from 1 to 1 (it is quite easy to use wget and some lines of perl code to extract the whole database this way). You can try to limit the rate of requests from a single IP address and stuff like this, but this only slows down things. And you can not use security settings here, because everyone is meant to be able to view each entry (only not all of them). I did not yet have to solve a problem like this (only discussed it). You could probably use some alternate keys, created as hash values from your primary key and some secret string, or use UUIDs like Cesar Lesc mentioned in his post on this thread. Best Regards, Christoph On Apr 23, 2008, at 04:08 , Jim wrote: Hi Christoph, I know you're mostly asking about best-practice of process rather than security, but I think it's nonetheless important to bring up the issues that can arise when embedding primary keys of your entities client-side. I'm still a T4 user, but when you say a PageLink on a PersonSearch page, which has the Person's primary id as context, I assume that's analogous to the parameters attribute on a DirectLink in T4, in that the parameter is embedded in the page. Even if that's not the case, I'll continue anyway :P Building on your example, let's say that the logged-in user should only be able to search/edit people within his/her department. If we're only passing the PersonID to the PersonEdit page, and that ID is embedded in each rendered link on the PersonSearch page output, then the user could hack the form/link from the PersonSearch page to pass an arbitrary PersonID to PersonEdit, potentially giving the user the ability to perform unauthorized edits. I've started taking the approach of embedding not the ID, but a piece of information that's unique within the security-context (by security-context, in this case I mean department). In this case, assuming that a person's full name is unique within a department, we could embed the person's full name into the PageLink, and the PersonEdit page would search not on the primary key of the person, but instead on the combination of the DepartmentID (retrieved from the session if we're keeping a User object in the session) and the full name we passed in. Since we're using the DepartmentID from the session, then the user can hack the form/link all he/she wants, and the best they'll do is bring up the editing form for someone that wasn't in the search results but is still in their department, so it'd still be an authorized action. This sort of approach is annoying, because we'd love to be cleanly using solid efficient primary keys, but it probably pays to be paranoid. Anyone have a better approach on this issue?

Re: T5: Forms - Best Practice
Hi Geoff,
it seems your JIRA describes just what I would like to have. I
especially like the idea with the conversation id, because my next
thought would have been: what happens if the user edits two different
persons in two different windows of his web browser at the same time
(over a slow network, it might actually be not too difficult to have
the two requests for each page interleaved).
Unfortunately, there does not seem to be a lot of interest in your
issue, no fix version, no assignee :(. I just voted for it, maybe this
helps (I know, the best thing would be to fix it myself, but this
seems to be a bit big for a first contribution).
The conversation id would be a nice tool anyhow, this way you could
persist things in the session without having to worry about different
requests to the same page mix things up. Is there something like a
conversation id in Tapestry right now?
Best Regards,
Christoph

Maybe someone on this list can help with some ideas.
As an example, lets have a PersonEdit page, with a PersonDao
injected. You can create new Person entries or edit existing ones.
To edit an existing person, there is a PageLink on a PersonSearch
page, which has the Person's primary id as context. To create a new
Person, a PageLink with 0 as context is used. To make this work, we
have onActivate() and onPassivate() methods in PersonEdit:
void onActivate(int id)
{
_id = id;
if (id == 0)
{
_person = new Person();
}
else
{
_person=personDao.get(id);
}
}
int onPassivate()
{
return _id;
}
This way we can avoid using @Persist on the Person property
(because, for instance, we want a user to be able to open two
browser windows, viewing two different Person entries side by side
and edit and save both of them. I think this would be problematic
if we use @Persist, but please correct me if I am wrong).
Now, editing an existing user works like this:
- click the edit user XYZ PageLink on the PersonSearch page
- in onActivate(), the personDao is used to query the Person from
the database
- an HTML form is rendered to let the user edit the values
Up to here everything looks perfect.
- the user edits the Person's data and hits the save button
- onActivate() is called, a fresh Person is loaded from the database
- for each field in the HTML form, validation is done (if defined),
and a property in the fresh Person instance is set if the
validation was successful
- onValidateForm() is called if existing to allow for cross-field
validation
- if all validations were successful, onSuccess() is called. Here
we call _person=personDao.save(_person). This save method returns a
new Person instance, exactly as it was written to the database
(primary id may be generated by the database, time stamps or
version numbers updated, ...). We use this new Person's id :
_id=_person.getId() to make sure we have the correct if for the
next onPassivate()
- onPassivate() is called
- result sent to browser, redirect
- onActivate() loads Person again
- new form is rendered
This is good, but I think it could be improved.
1. The Person is loaded from the database twice (using
personDao.get()), and saved once. The save() method of personDao
already gives us a new, fresh instance of Person, it seems like a
waste to load it again after the redirect.
2. During validation, we check if there is already a Person with
the same userid (in onValidateForm(), or in onValidateFromUserId())
and warn the user if this is the case. But what happens if a new
Person with this userId is added just after onValidateForm() is
called, but before onSuccess() is called, where we want to save? To
make our program solid, we have to take this into account. In case
save() does not work, we do not want to see some exception page,
but the form, as it was filled, with a hint what might have gone
wrong, so the user can try again. To make this possible, we have to
move the save() to onValidateForm(), because there we can still
record form errors (I think there is a JIRA for an improvement to
this situation).
3. We want to give the user feedback of what happened. After
clicking the save button, we want to show a message like
Successfully saved new person information above the form (at the
same place you would see error

Re: My breadcrumb component from T4 to T5
Hi,
I'm not sure if I understand...
Do you mean to say that manipulating the breadcrumb path (adding or
removing crumbs) should/could all go into one event handler?
-J.
Ah, by workflow I meant to ask when you expected the events to get
fired, which you answered for the onactivate handler.
So, why not do this all in one event handler, perhaps setupRender?

beginRender will
: create a bookmarkable link
: store (if necessary) in the model of breadcrumbs.
onActivate gets called whenever a breadcrumb - rendered as link is
clicked
and will
: remove a crumbs that are listed after the clicked link, cleaning up
the trail
I think the workflow is okay - as it is proven in T4. I'm just looking
for
the correct points to hook it into T5.

Hi,
Need some advice. In T4 I had a breadcrumb component that got its
information from a breadcrumb model structure. Each page that needed
to
go
onto the crumb path would implement some base page class. This page
class
implemented PageRenderListener and IExternalPage. The former to add
info
to the model and the latter to remove info from the model (btw the
breadcrumb model was an ASO).
Basically the model consisted of some key, name/title and
(constructed)
link tuple. The link basically pointed to an IExternalPage
implemented
page class - so to be precise the whole breadcrumb path consisted of
bookmarkable pages.
I'm trying to mimic this behavior with T5, using the BeginRender
annotation on a basepage class method called initPage() and also on
the
basepage class a onActivate() method. I have some questions about it.
Below the specific base page code:
protected String getBreadCrumbTitle() {
return resources.getMessages().get(title- +
resources.getPageName().toLowerCase());
}
protected Object[] getLinkParameters() {
return null;
}
@BeginRender
public void initPage() {
String pageName = resources.getPageName();
Link link = resources.createPageLink(resources.getPageName(),
true, getLinkParameters());
breadCrumbHolder.checkBreadCrumbForAdd(pageName,
getBreadCrumbTitle(), link.toRedirectURI());
}
public void onActivate() {
String pageName = resources.getPageName();
breadCrumbHolder.checkBreadCrumbForRemove(pageName);
}
Q1: the initPage() method is there to create a 'bookmarkable' link -
amongst others - and store that information in the breadcrumb model.
The
getLinkParameters() is there for a subclass to provide its specific
activation parameters to be used. Should I use another way to create
bookmarable links?
Q2: the onActivate() method is there to remove one (or more) crumbs
from
the crumbpath. Since other pages will also need activation -
potentially
with additional arguments - is this onActivate() the best way/place
to
manipulate the model? I'm getting the idea that onActivate() is not
the
designated alternative for T4's activateExternalPage(Object[]
parameters,
IRequestCycle cycle) in IExternalPage interface.
Currently all of this works - although haven't tested activation with
activation context parameters yet.
Thx.

Sure, couldn't they? I'm not sure why they are split up into the two
different event handlers. Except in the case of action links and form
submission both the onAction and beginRender events are going to fire
in a request. You haven't mentioned a need to do anything different
with the information between when the two events fire, so why not
handle it in one place?
Or am I missing something?

Is it possible to receive uploaded files from non-tapestry pages?
Hi.
I wrote simple HTML like below
start.html:
form action=/myapp/upload
method=post enctype=multipart/form-data
input type=file/
input type=submit/
/form
and very very simple tapestry codes.
Upload.java:
public class Upload {}
When I press submit button in the HTML file,
following error is occurred.
What I should to do?
Thanks for advice.
