Re: Parameter has already been declared

try changing string[] to Collection and see if this changes
anything, tapestry is probably able to coerce these values, isn't it?

Re: "Library 'contrib' not found in application namespace" when use Tree component

try to write some nonsence the application xml so it won't render (an

Re: making links :visited across components

:) yes, I am busy.

I will try to demonstrate it:

===
INSTEAD of implementing the pager like this:


  




and using it like:




THE NEW WAY is:


  
  
  
  


and using it:


  


...


  





to make this work I added to the pager:

@Parameter public abstract String getLinkText();
@Parameter public abstract int getLinkPageNumber();
@Parameter public abstract boolean isLinkSelected();

and

public void updateOutParameters(String text, int pageNum ) {
  setLinkText( text );
  setLinkPageNumber( pageNum );
  setLinkSelected( pageNum == getPageNumber();
}

Note that the pager does not only generate 1 2 3 links but also << and
>> links to move forward and back, so i need the linkText and can not
just use the page number as link text.

Further, an If was required inside the linkBlock because if the pageNum
is 0, I need to generate another link which will be the default link to
the page instead of a direct link, since page number 0 is probably
visited once the page is first accessed...

so it is:


  
... generate a link to the page, which will be "visited" anywayz

 I have a nice usability problem with direct links nested inside

 I have a pager component, which takes an in-out "page" parameter.

 The pager component generates direct links, which invoke a listener in
 the component with the page number as parameter.

 The listener calls the set method of the "page" parameter, thus
 changing the page number.

 Now if I drop two instances of the pager component in a page, they
 both generate different links, so visited pages can not be traced:

 if the user clicks "2" on the one pager, the url is:

 http://localhost:8080/bardtke/reg/Forum,$Pager.$DirectLink_1.sdirect?sp=1


 on the other pager, the url is:

 http://localhost:8080/bardtke/reg/Forum,$Pager_0.$DirectLink_1.sdirect?sp=1





 so if on pager 1 page 2 is marked as visited, on pager 1 it isn't :(

 Now thats a fine problem...

 Any idees ?

Re: reading a file in web root in a Tapestry fashion

[Ron Piterman]

for example, you can not expect hivemind to inject IEngineService
automatically since there are many services implementing this interface
(PageService, ExternalService, DirectService and so on)


Otherwise it works fine.

Ron

Re: reading a file in web root in a Tapestry fashion

[Ron Piterman]

yes, thats it - BTW, you don't need an explicit set-service.
just exposte a setter in your implementation class, and hivemind will
autowire it:

public void setServletContext( ServletContext ctx) {...}

Re: Tap4 documentation: the For component example is not complete

[Ron Piterman]

Hallo cyrille,

Its under project information (bottom of navigation) /Issue tracking

http://tapestry.apache.org/issue-tracking.html


You are in a very good situation to help improve the docu, becuase you
are learning tapestry from ground up, and doing it very thoroughly- so
its really important you add jira issues if you find something is
missing/wrong - also if its just a typo -

later you just oversee such things, because you use the docu as
reference only... keep up the good work :)

Cheers,
Ron

Re: hook into T4's page creation process

[Ron Piterman]

yes, there is a configurable annotation workers, so you can
create/extend/override page methods when tapestry is preparing the
page/component class.

You can create your own class worker which will add the needed logic to
the mentioned attach event.

Take a look at the annotations module code and hivemind configuration.

Cheers,
Ron

Re: Standalone plugins

[Ron Piterman]

again, the trick is adding references to a library without coding it.
Tapestry defines in the hivemind registry the service point :

tapestry.parse.SpecificationSource

which is responsible for reading the specification from files - I would
think that to make dynamic libraries load, you need to implement this
service a new:

create a single library which is "dynamic", all other libraries will
delegate to the tapestry implementation.

for your dynamic library, create a specification which is dynamically
generated according to a hivemind configuration point.

Never done this, but was often thinking about it...

Cheers,
Ron

Re: Standalone plugins

[Ron Piterman]

It could be done, but above all needs restarting of the servlet
container for every change-

Since hivemind lets you peekup configuration from every jar on the
classpath, configuration isn't an issue.

However, adding a library without making an explicit reference to it
should be quite difficult - You may need to create a custom Library spec
source.

Cheers,
Ron

AFAIK, "client" uses cookies.

T41: RedirectException and async?

[Ron Piterman]

I have a small security workflow which is heavily based on 
RedirectExceptions - and was wandering how the tapestry javascript would 
accept this -


When a page is accessed with unsufficient permitions, a 
RedirectException is thrown.


Now, what if the request is async ?

Ron

And, the coolest thing is that this sort of thing *can* be inherited
without using annotations (by putting it in a common superclass).
Otherwise, you have to use XML in your spec files to inject stuff into
all of your subclasses.

What version of Tapestry are you using?  4.1?  If so, then it can
autowire stuff for you out of the HiveMind registry.  Just declare an
abstract getter that returns an ApplicationStateManager.  If you're on
4.0, you can download the tapestry-autowire source and build it (via
SVN http://svn.javaforge.com/svn/tapestry/tapestry-autowire/trunk/,
username/password anonymous/anon).  Just drop it into your classpath
and it will do the same thing as 4.1.

Greg,

You can do what you described before, but pull your visit object in your
SomePage.java classes where you need it.  As Ron pointed out, ASM uses
other service where WebRequest is required.  When you're using it, it's
still null.

Jim Steinberger wrote:

Just wanted to give a heads up on a gotcha I ran into.

 


The "index" value of the "foreach" tag is stored as a String, not an
integer, so be careful when using it to, say, index into an array.

 


e.g. If you have a two-dimensional array stored in the input-symbol
"matrix", the following will work fine:

  ${matrix[0].length}

 


But the following, where "matrixIndex" is the symbol used for a
surrounding "foreach"-tag's "index" value, will throw an error:

  ${matrix[matrixIndex].length}

 


The error will tell you that "matrix" does not have the property: 0.
i.e. since matrixIndex is a String, it's looking for a property of the
array-object named "0".

 


This issue hadn't hit me before because OGNL casts it automatically when
used in expressions like: "${matrixIndex > 0}".  But since a
String-input is valid as a [] parameter in OGNL, it doesn't know to cast
it.

 

 


I used the workaround:

  [EMAIL PROTECTED]@parseInt(matrixIndex)].length}

[ANN] tapestry revisor: syntax checker for tapestry

[Ron Piterman]

Hi All,

I just uploaded a very early release of tapestry revisor to

http://www.piterman.net/tapestry-revisor-0.1.zip


Tapestry revisor is a syntax checker for tapestry 4.0 and 4.1.

It currently runs as a standalone application, easily launched from an IDE.

Integration with IDE is in plan.

Some issues are still present, especially with injected objects such as 
EJBs - but I use it in an JBoss project, and it works fine as long as 
JBoss is running.


In the Zip file is a jar and a readme.txt which explains how to run.

Cheers,
Ron

getPage().getRequestCycle().getInfrastructure().getApplicationStateManager()

take the getPage() out when the class is a page class.

So your are also in europe?

Currently, a list of objects is returned from the model, for each one 
getPK and getLabel is called.

It doesn't really mutter if the objects are the same as the value or not.

The same getLabel and getPK are also called with the Value of the

(entity) or an Object[]...


Better?

you can change your model to extract object[0] as key, object[1] as

Sorry for the late reaction but I think the previous version was 
better. I explain why.

In my application I use Autocompleter to list Hibernate objects.
Until this modification my query was:

   SELECT o.id,o.text FROM ... WHERE filter condition

but now I have to write

   SELECT o FROM ... WHERE filter condition

so the query must return full objects, it may require much more DB 
bandwidth.

I see that Autocompleter's implementation is now very clean

   key = model.getPrimaryKey(value);
   label = model.getLabelFor(value);

but it may have negative performance impact in case of more complex 
applications.


Sorry if I misunderstood something...

Re: IAutocompleteModel change

[Ron Piterman]

BTW - I am the initiator of this change - sorry if I made you any 
trouble, but I hope you can also see the benefit...


If you follow my prev. posting, I you should also add a class check in 
the getPK and getLabel - because the value object is also passed to 
these objects. - I agree, its not s clean...


I hope soon one (jesse :) ) would add a translator to the property 
selection / Autocompleter - so it might help solve such problems...

Re: IAutocompleteModel change

[Ron Piterman]

I think you get a List from hibernate?
you can change your model to extract object[0] as key, object[1] as 
value, and return the whole object for getForPrimaryKey( key ) - ( I 
think its another method signature- but the same meaning)...

Re: For loop Rewind problem

[Ron Piterman]

Tapestry traces the rendered components and uses this info on rewind - 
its better not to temper with that.
If you need JS magic, try using T41 - using Ajax this should be 
possible, though only straight-forward for jesse and other enlightend 
developers :)

Re: Moving Components inside a Border Component...

[Ron Piterman]

well, it should work - check if tapestry is actually using your border's 
class, it might be you have a configuration error somewhere...


This should be quite clear if you examine the exception page tapestry 
generates: NoSuchPropertyException - look on which class there is no 
such property...

Hi!

Let's suppose one component named  XPTO, that takes one parameter PARM.

So in my "normal" Home page I use it like this:



This is ok, I think.

Now I move that line to inside the HTML new component named Border.

So my Home page becomes:



And Inside the new Border HTML, I put the same line above:



What happens now is that I get an exception saying that can't parse the OGNL

I've moved the property accessors to the Border.java, but still it doesn't
work.

The exception is:

# ognl.OgnlRuntime.getProperty(OgnlRuntime.java:1616)
# ognl.ASTProperty.getValueBody(ASTProperty.java:96)

T41: how to render the ID attribute in an abstract component

[Ron Piterman]

Hi all,
I have an custom component which is inheriting from AbstractComponent - 
it is a custom image, which renders  - now what would be 
the right way to render the ID attribute into it ( the clientId which is 
auto generated... or an informal id parameter) ?

Re: Some Redirect after Post issues

Did you try to use
@Persist("client:page") ?

this will encode your property in a hidden form field (and in links 
URLs, so the become quite ugly) - but you don't need the hidden fields...

Yes, this is my actual workaraound for the problem. But this means that

This, (though I dislike it) could also work:

Maybe I'll try that one :-)
I could make an empty page which is used only for redirect-after-post 
and which has no page validation listener or begin render listener. 
However, this is also quite confusing since the listeners are in a 
separate class...

Re: 4.1 Stability (Hi Jesse! :P)

[Ron Piterman]

If you need ajax, you can't go around 4.1 - if you don't, 4.0 has some
advantages (as far as I can see) - such as much smaller javascript
footprint for form validation, and stability -

However, Jesse does a great work in fixing bugs in 4.1 very fast, I go
to sleep in Europe and Jesse fixes the bugs at day time in the states,
so the next morning a new version is out - thats amazing !

It is not so easy to recommend anything in active development for
production - I can just say - I am working on a project which should go
in production on Jan 1st and am using 4.1 ---

Hijacking threads is an antipattern ;)

The formatter is the standard Java formatter - so I don't escape
anything - I count on tapestry to do that.

The wrapper format object does not do anything with formatting, it just
manipulates the passed object before this is formatted by the java
currency format - it takes the long and passes a float which is the
original long divided by 100.

If I would, i would have used the tapestry configuration to change the
encoding - but actually I don't change the encoding at all, tapestry is
using utf-8 by default.

The line showing the meta in my postings was not taken from my template,
but from the html tapestry's shell component renders.

Tapestry is set to use utf-8 by default - and I suspect it gets a string
"€ 1000" - and should encode it the right way.

I will look again at this problem at friday, and will debug into it to
learn more - this is somewhat heavier because using jboss, so debugging
isn't fun at all :(

Just a guess. You are using a number format without specifying
the locale. Hence, the default locale for your platform is
used which propably includes the encoding latin9. The code
which denotes the euro symbol in latin9 denotes the currency
symbol in latin1 and (IIRC) in UTF-8. Thus, you see the currency
symbol, not the expected euro symbol.

One thing has changed: I've started using UTF-8 encoding for my webapp. I
have a filter that enforces characterEncoding UTF-8, and my html and
.application file are also configured to use UTF-8. I'm suspecting the

to do. I've tried rolling back to ISO-8859-1 like before, but nothing
happens. Don't know if I managed to remove all UTF-8 references completely

Has anyone experienced something similar? Is this an encoding issue or

something else?

Re: Multiple browser windows causing session issue

[Ron Piterman]

It depends on the setup of your wizard, if it a single page iterating 
over components or a series of tapestry pages following each other - but 
either way you prevent such problems by persisting flow information in 
the client, not as cookies but on a page - based in URLs.


You should always keep in mind the information flow and know what is 
stored where, this will keep you out of such troubles.


For example, you may persist some information as hidden fields in your 
form. However, you can not do this if you use Autocompleter or other 
json requests, since they don't submit the form.


In such cases you can use the excelent @Persist("client:page") which 
will store everything inside URLs, but will not persist across pages: 
component X with a persistant property on page A and component X - the 
same component - on page B will not share the data, you will have to 
activley "transfer" it either in your listener code (submit or direct 
link) or via an external link.

Ron

Re: @Asset problem

[Ron Piterman]

You are mixing between creating assets and defining them.

The annotation is defining an asset, and what you probably want is 
create a new one on the fly.-


To do so, you need to inject one of the AssetFactory services from here, 
and use it to create one on the fly...

Hi,

I am now a big fan of tapestry annotations since everything stays neatly in
one place, except in one area which still bothers me. I want to specify
assets like stylesheets and such in a Border component that can be used by
the rest of the pages and the whole app looks uniform and so on and so
forth.

But I also want to be able to change the stylesheet name at deploy time,
without having to recompile and redistribute the war file, in other words
bother the developers whenever I want to change it. So I thought may be I
can declare it as a key (stylesheet = css/mycss.css) in the
app.propertiesfile and pick it up in Border component.

@Asset("message:stylesheet") - This isnt working. I dont know whether its
supposed to.

I went ahead and tried this -
public IAsset getStylesheet() {
   return getAsset(getMessages().getMessage("stylesheet"));
}

However this code always returns null. I guess the asset needs to be
registered much ahead, (there is some code I see in AbstractComponent which
uses a map to store references of assets). So how am I supposed to setup
dynamic assets? Is there a way of creating assets when required? I remember
having read something about this but I am unable to find it. I would be
grateful if you could point me in the right direction.

Thanks,
Srini.

Re: Dynamic Working with Tapestry...

[Ron Piterman]

Tapestry uses for validation the ValidationDelegate - I would recomment 
you stick to it, it will make your life much easier, and it is one of 
tapestry's most powerfull features:


You can use validators on each of your fields, and that doesn't mean 
they have to be preconfigured - you can use a dynamic list of Validator 
objects, depending on the current iteration (maybe not all a required).


So all you have to do is

@Bean
public abstract ValidationDelegate getDelegate();

and



and in your submit listener:

if ( getDeleagte().getHasErrors() )
  return;

Take a look at Form validation in the users guide.

Cheers,
Ron

Ron Piterman-2 wrote:

If I get this right, there is some kind of iteration over objects inside

When the form is submitted, the iteration will be performed again, this 
one updating the values.
then you add an "action" binding to the submit, and persist the whole 
list of obejcts which were updated:



 
  
 
 


the currentValue property will point to the current iteration value, and 
the input will update each object in the iteration.


Did I get it right this time?

Ron Piterman-2 wrote:


There are some approaches to that problem, one approach would be to use 
the parameter binding for that:


The component gets a paraemter from its container, and is responsible to 
update the parameter.


Say you have a property on your page/container component:

public Data getData() {...}
public void setData( Data data ) { // now perform the save }

you pass "data" as a paraemter binding to your component which includes 
the form, and on your submit listener, after verifying everything is 
fine, you call setData:


@Parameter public abstract Data getData();
public abstract void setData( Data data );

public void doSubmit() {
 // validata...
 // check that everything is ok...
 if (getDelegate().getHasErrors() )
   return;
 setData( getData() );
}


Another approach would be to use an IActionListener as paramter and 
invoke it - this is the approach I take usually.


Hope that helps,

Re: 2nd try: ajax updating components inside a For

[Ron Piterman]

Thanx jesse, thats great !

I guess I miss some basic understanding of how for works in ajax 
context, but I still didn't manager to update a single iteration -


Currently it only works if you update the container of the for, and 
still there are some issues with multiple posts (I added a jira issue).


Would you/? explain what would be the preferred way to solve this prob 
(updating a form inside a single iteration)?


Cheers,
Ron

Hi all,
I have a simple For loop which iterates over some object.
the objects are all rendered to DirectLinks.
When a DirectLink-listener is called, the clicked Item should change to
"edit view" and render a Form instead of the Link.
When the form is submitted, the item should render again to the Link (
"view mode").

Now the question is, how to change the code below, to do the trick with
ajax.

When using normal http requests the page looks like this:


  
try ajax with list 
 
  


  

  
  
  

 
 
  

  
 

 

  


and the class:

public abstract class Home extends BasePage
{
 public Object getObjects() {
 // return the list of obejcts
 }

 /** the value of the current iteration */
 public abstract Value getCurrentObject();

 @Persist
 public abstract Value getEditObject();
 public abstract void setEditObject( Value v );

 public boolean isEditMode() {
 return getEditObject() != null &&
 getEditObject().equals( getCurrentObject() );
 }

 public void edit( Long id ) {
 setEditObject( getObject( id ) );
 }

 public void doSubmit() {
 // ... save ... and then
 this.setEditObject ( null );
 }

 public void doCancel() {
 this.setEditObject( null );
 }

 private Value getObject( Long id ) {
   // ... return the value for the given id
 }

}

Actually, as i understand it, if you contribute to

the original provided by tapestry.
e.g.: I want to override Home service so it uses my own

In my hivemodule.xml i would put:

You can replace an implementation of a service by providing another

But it sounds more what you need is to intercept the services - take a

Re: Dynamic Working with Tapestry...

[Ron Piterman]

If I get this right, there is some kind of iteration over objects inside 
the form component.
When the form is submitted, the iteration will be performed again, this 
one updating the values.
then you add an "action" binding to the submit, and persist the whole 
list of obejcts which were updated:



 
  
 
 


the currentValue property will point to the current iteration value, and 
the input will update each object in the iteration.


Did I get it right this time?

Cheers,
Ron

Say you have a property on your page/container component:

public void setData( Data data ) { // now perform the save }

you pass "data" as a paraemter binding to your component which includes 
the form, and on your submit listener, after verifying everything is 
fine, you call setData:


@Parameter public abstract Data getData();
public abstract void setData( Data data );

public void doSubmit() {
  // validata...
  // check that everything is ok...
  if (getDelegate().getHasErrors() )
return;
  setData( getData() );

Another approach would be to use an IActionListener as paramter and

2nd try: ajax updating components inside a For

[Ron Piterman]

Hi all,
I have a simple For loop which iterates over some object.
the objects are all rendered to DirectLinks.
When a DirectLink-listener is called, the clicked Item should change to 
"edit view" and render a Form instead of the Link.
When the form is submitted, the item should render again to the Link ( 
"view mode").


Now the question is, how to change the code below, to do the trick with 
ajax.


When using normal http requests the page looks like this:


 
   try ajax with list 

 

   
 
   
 
 
 
   


 
   
 

   

   
 


and the class:

public abstract class Home extends BasePage
{
public Object getObjects() {
// return the list of obejcts
}

/** the value of the current iteration */
public abstract Value getCurrentObject();

@Persist
public abstract Value getEditObject();
public abstract void setEditObject( Value v );

public boolean isEditMode() {
return getEditObject() != null &&
getEditObject().equals( getCurrentObject() );
}

public void edit( Long id ) {
setEditObject( getObject( id ) );
}

public void doSubmit() {
// ... save ... and then
this.setEditObject ( null );
}

public void doCancel() {
this.setEditObject( null );
}

private Value getObject( Long id ) {
  // ... return the value for the given id
}

4.1 : updating components inside a For

[Ron Piterman]

I Guess this is a frequent question, yet I could not find an anwer in 
the forum:


I have a for iterating over some objects, generating a list of direct 
links ( "view mode").


what I want to achieve is that when a link is activated, only the 
selected item refereshes to a form ("edit mode"), which on submit turns 
back to the "view mode".


How do I refresh only one instance of the iterated list.

Trying to refersh just the iterated item or even the whole list gives 
all kind of errors about no id found of some hidden field in the form 
and so forth -


So a small overview of the required flow would be great :)

Re: Validation questions: components and messages

[Ron Piterman]

Yes - you can do much with the delegate :)
BTW - consider using CSS for this instead of adding elements , it might
be more elegant and easier to maintain...

You use per Form one instance of validation delegate. It tracks the
validation errors which the components report. This happends from
itself, you just need to define the validators on the fields.

In such a case you need to create your own class, extending the standard
validation delegate. There are methods which allow the delegate to hook
up into the rendering of fields and their labels, so you can do just
what you described.

Re: Accessing HiveMind Registry

[Ron Piterman]

One way would be to create a factory for instances of this class in
hivemind, and inject any services you need to it.

Another way would be to get the registry instance tapestry uses, which
is stored as a context attribute. see the ApplicationServlet code.

Re: Form submitting problem

[Ron Piterman]

Me again...

Two things: the exception page is not for business logic exceptions but 
should be used as a fallback in case of dev mistakes (also known as 
bugs) and in case someone tempers with your application and sends wrong 
information in the URLs.


Tapestry's Form handling is one of the framework's best and most mature 
features, which , imho, makes this framework so important. If you don't 
use it - you miss a great feature.

Ron

Re: Form submitting problem

[Ron Piterman]

Still you can use validation.

Instead of catching the exception in the engine, and forward to the 
exception page, catch the exception in the page's class, and record an 
error in your ValidationDelegate.


instead of :

getSomeService().save(foo);


use


try {
  getSomeService().save(foo);
}
catch (Exception ex ) {
  record( ex );
}

where the record method adds an error to the validation delegate.

Hope that helps,
Ron

Re: Creating listener urls

[Ron Piterman]

Sure - so, what is that you are asking? how to generate an URL?

In Tapestry, EngineService is responsible to generate URLs and respond 
to them.


Implement your own service and let it check for a request parameter you 
add in your java script.


You will however have to pass a basic url (generated by your service) to 
the javascript, if you want to do thing right.

If you don't, you can write the URL from scratch in Javascript:

app?service=myservice&myownparameter=somejavascriptvalue

But i would keep away from that sort of thing.

Cheers,
Ron

So My idea was to create an AjaxSend service + component. The

Problem is, I'm dealing with a lot of those components on my screen.
Cuz for each listener in the page I add a component (Bad design I
know). So my question is:

Would be possible to have just one script: let's say:

function asynchSend(url,params[]){
... ajax stuff here
}

and then on my Page, I have methods that would return the Listeners 
urls? like :


public String getLogoutLink(){
return the url to the logout method ...

Is this possible?

Re: Redirect to page on F1 keypress

[Ron Piterman]

If each page has only one F1 page, or, say a limitted number of F1 - you 
implement a javascript listener and uses JS to redirect (I don't know 
the exact call) -


The URL is passed to your .script file - you get it by using the 
relevant engine service's getLink method. I think they did exist in 3.0.


Cheers,
Ron

Tapestry uses a pool to store page instances. While rendering it is 
safe to use instance variables but you have to make sure they are 
reset, preferrably in either pageDetached or pageAttached events.
If you don't reset them, information can be shared between many users 
of your site, but not by all, since they might get another instance 
from the pool.


When using abstract properties, tapestry does the initialization work 
for you.


Hope that helps,

Re: Problem with parameters of a custom component (Tapestry 4.01)

[Ron Piterman]

:)

Tapestry uses a pool to store page instances. While rendering it is safe 
to use instance variables but you have to make sure they are reset, 
preferrably in either pageDetached or pageAttached events.
If you don't reset them, information can be shared between many users of 
your site, but not by all, since they might get another instance from 
the pool.


When using abstract properties, tapestry does the initialization work 
for you.


Hope that helps,
Ron

Sorry. What I mean by does not work is that getLocationOfStore() in my 
component is null after the component renders.
When I use the updated code below the storeLocation is passed through to 
the component and getLocationOfStore() contains the location I passed in 
from the page.
It does not like it when I use abstract getters and setters but I dont 
understand why.


Thanks

Re: Tapestry / Spring / Hibernate / Tomcat strange error

[Ron Piterman]

I would check your urls: you probably try to access an engine service 
which does not exist. either through an url or when generating a link?
check the url which generates this exception, specifically the service= 
parameter ( if using roude URLs ).

If you are using fiendly URLs, try to see which encoder makes problems.
Cheers,
Ron

Re: upgrading to 4.1 - question about concepts

[Ron Piterman]

Jesse Kuhnert wrote:

Those sound like requirements :)

This is good, I hadn't fully attacked/handled widget support yet (hence the
lack of seeing very many), but I'd love to be able to pick your brain about
more specifics of what/how/why you are doing some of the things with your
widgets. (If it's not a public sort of thing you can email me off list).


thanx jesse,

The most simple example here is a selection of a table row. We use 
tables extensivly, and one of the most common actions is selecting a 
table row by clicking on it.


What the user sees is that the row is selected (a class name is added, 
and removed somewhere else, the background color changes) - but actually 
the row widget sends a request to the server - using a plain tapestry 
listener url. the listener method changes the application state and then 
renders a


true

the row widget recieves this xml, lets dojo parse it and invokes all 
 elements in it, in this case the selectRow method.


So I don't need to generate javascript from tapestry. ever. Everything 
is a widget and an rpc. I find it very comfortable and clean, and since 
the widget is corresponding with its tapestry component, the tapestry 
component just has to "know" the widget (which actions it supports).
Its really like two systems (tapestry and dojo) work together through an 
API. I find the tap4.1 way of using dojo is very much event oriented, 
while the way I use dojo is very much encapsulating everything inside 
widgets.


One of the common actions, which is implemented in a base widget from 
which all inherit is a "replaceById" - and there are some other like 
"redirect" and so on.


Going back to the example above:
It seems very very easy to create from tapestry the event TR.onclick but 
how to I render the response?
At the moment I would guess that I have to generate some javascript from 
tapestry which does the work, don't I ?


Cheers,
Ron



The format is currently "similar" to tacos, though handled a little
differently.

The client side file that handles the xml-rpc sort of calls is
http://svn.apache.org/viewvc/tapestry/tapestry4/trunk/tapestry-framework/src/js/tapestry/core.js?view=markup. 



The element types/id's mostly come from the ResponseBuilder interface,
http://tapestry.apache.org/tapestry4.1/tapestry-framework/apidocs/org/apache/tapestry/services/ResponseBuilder.html 


.

I don't know if I can promise anything this extensive being done in one
weekend but the more input I can get the better. (for day to day 
pondering's

sake )

Re: Different JSESSIONID in Cookie and URL?

[Ron Piterman]

hello Christian -

As far as I know the session is managed by tomcat ( or any other 
container ) - so maybe the tomcat list is a better place to ask...


but since it is managed by the container, I would suggest that relying 
on a session id taken either from the url or from the cookie might cause 
some problems if you change the container configuration.


If you want to implement long sessions or store some extra session 
information outside of the session map itself (which seem to me two 
reasons to try to capture the session id) I would suggest creating your 
own id and, ofcause, store it in the session :)


Hope that helps,

Cheers,
Ron

If I open this app in the browser, I'll first get a cookie with  
JSESSIONID X. Then, on the page shown after the page redirect has  taken 
place, the app is using a different JSESSIONID in its rewritten  urls 
("/XYZ/app;jsessionid=Y").


In the end I turned off cookies for my app to make it work properly.  
However, my question now is "why"? Why are the session ids from the

Re: ASO & Interceptor

The simple approach is to use the 
http://tapestry.apache.org/tapestry4/tapestry/hivedocs/service/tapestry.state.ApplicationStateManager.html

service, either autowired or specifically set to your interceptor service.

Another version which I use is create one hivemind service with getters 
for all of your state objects - the implemntation uses again the service 
mentioned  above, but I like it because its easy to maintain.

is in the same jar.


Thanx,
Ron
