Re: Tapestry 5 + JS framework

[Kristian Marinkovic]

Hi,


Tapestry 5.4 (beta) built-in require js support makes it really easy to add
other javascript frameworks cleanly. I'm currently working on T5.4 projects
that integrate with angularjs and backbone/marionette js.

Re: [5.4-beta-10] providedChecksum is always different from the actualChecksum for a specific asset

[Kristian Marinkovic]

how are you running your app? i'm using run-jetty-run in Eclipse and never
experienced the problem you describe. the etag is based on the content of
the file. maybe there is another eclipse plugin changing your resources

Re: Forms require that the request method be POST

[Kristian Marinkovic]

Hi,

check if it is the same client. i once had the same problem. After several
hours of investigation it was a developer with a browser plugin (web
developer) which enabled converting form post requests to get requests.

hope this helps.

Hi Jens,

never seen an exception like that but i'd guess a namespace is missing.
either tapestry or xml

Re: Tapestry with Jetty behind https frontend

[Kristian Marinkovic]

hi all,

going through the posts i realized there is an easier solution missing.

What i do is to contribute a HttpServletRequestHandler that checks for the
X-Forwarded-Proto header and - in case its set - wraps the
HttpServletRequest with overrides to isSecure(), getScheme() and
getServerPort(). All the other stuff in Tapestry regarding https works
unchanged.

g,
Kris

public final class HttpsFilter implements HttpServletRequestHandler
{
private final HttpServletRequestHandler delegateServletHandler;

public HttpsFilter(HttpServletRequestHandler delegateServletHandler)
{
this.delegateServletHandler = delegateServletHandler;
}

@Override
public boolean service(HttpServletRequest request, HttpServletResponse
response) throws IOException
{
return delegateServletHandler.service(wrapRequest(request),
response);
}

private HttpServletRequest wrapRequest(final HttpServletRequest request)
{
final String protocolHeaderValue =
request.getHeader("X-Forwarded-Proto");

if ("HTTPS".equalsIgnoreCase(protocolHeaderValue))
return new HttpServletRequestWrapper(request)
{
@Override
public boolean isSecure()
{
return true;
}

@Override
public String getScheme()
{
return "https";
}

@Override
public int getServerPort()
{
return 443;
}
};

return request;
}
}

Re: Content Security Policy without unsafe-inline

[Kristian Marinkovic]

i also think it's up to the development team to decide how they want to
develop (inline-scripts vs. no inline-scripts). sometimes inline-scripts
make things easier. having a choice is good anyways.

still, do you think it is worth moving the requriejs specific
inline-scripts into a dynamically generated js file?

Re: Content Security Policy without unsafe-inline

[Kristian Marinkovic]

looking at my migrated Tapestry 5.4-beta-2 app i can only see two inline
scripts. The requirejs configuration (shim, ...) and the require call
itself.

Is it possible to move those into a dynamically generated js instead,
that's included with a script tag? the requirejs config could by cached.
And the require call would be page specific. Should we create a jira ticket?

removing the javascriptsupport methods is not a good idea as it breaks
backwards compatibility. on the other hand removing in 5.5 would be nice :)

Kris

Btw. I just realized that the ETag value is double quoted (""56633""). Is

Re: Tapestry 5.4-beta-2 GoogleClosureCompiler

[Kristian Marinkovic]

Thank you for all your responses and references.

What i want to activate is the SIMPLE_OPTIMIZATIONS level that activates
whitespace removal and renaming (shortening) of variables and functions. my
webapp is getting used more by mobile clients (tablets, phonse) than
desktop clients. during testing and optimization i realized that the form
of the js -  eg. whitespaces - has an impact on the execution performance.
gzip does a great job in shrinking the file sizes but unzipping on a mobile
client has a performance toll which is noticeable on app startup leaving
the user with the perception the app were slow.

Kris

Tapestry 5.4-beta-2 GoogleClosureCompiler

Hi all,

how do i set additional GoogleClosureMinimizer options? The current
implementation in tapestry-webresources doesn't seem to offer any
configuration possibilities besides replacing the whole service.

Tapestry 5.4 require.js modules

[Kristian Marinkovic]

Hi all,

why are tapestry's requirejs modules nested in an anonymous javascript
function:

(function() {
   define(['jquery'], function($) {
   })
}).call(this);

isn't it enough to just write define(, function() {})? Is there a
reason for this additional scope?

cheers,
Kris



BTW, i just migrated an existing T5.3.7 application to T5.4-beta-2 with
almost no hassle. i'm really impressed.

Re: Keep the same form id after the zone refresh

[Kristian Marinkovic]

in tapestry your server side event handlers are not related to the client
side html ids. the client side html ids happen to use the server side
component id for convenience. An onValidateFromMyForm() handler will we
triggered even if the MyForm form is nested and updated in a zone.

Yes it is possible. Usually you use a Delegate component to render a Block.

Re: T5.1 -> T5.3 migration question

[Kristian Marinkovic]

Hi,

Tapestry over time added additional checks to detect whether the classes in
the Tapestry specific packages are really only relevant to Tapestry. Not
doing so can cause unexpected exceptions due to classloading issues.

in other words: only page, component and mixin classes go into the
respective packages. everything else should be moved outside (eg. base or
services)

not a big deal, just a precaution.

g,
Kris

Re: T5.4-alpha-1 is missing SystemPropertiesSymbolProvider

[Kristian Marinkovic]

Hi Howard,

yes the SystemPropertySymbolProvider is in place but in Tapestry 5.3.6
the TapestryFilter used it to resolve system properties but now it
doesn't. As a consequence properties like
tapestry.disable-default-modules that are accessed within the
TapestryAppInitializer cannot be read and therefore have no effect.

The code in T5.4 looks like this:
SymbolProvider contextProvider = new ServletContextSymbolProvider(context);
SymbolProvider contextPathProvider = new
SingleKeySymbolProvider(SymbolConstants.CONTEXT_PATH,
context.getContextPath());
SymbolProvider combinedProvider = new
DelegatingSymbolProvider(contextPathProvider, contextProvider);

  String executionMode =
System.getProperty(SymbolConstants.EXECUTION_MODE, "production");

  TapestryAppInitializer appInitializer = new
TapestryAppInitializer(logger, combinedProvider,
filterName, executionMode);


And the code in T5.3.6:
SymbolProvider provider = new SymbolProvider()
{
  SymbolProvider contextProvider = new
ServletContextSymbolProvider(context);
  SymbolProvider systemProvider = new SystemPropertiesSymbolProvider();

  public String valueForSymbol(String symbolName)
  {
   String contextValue = contextProvider.valueForSymbol(symbolName);
   if (contextValue != null) return contextValue;

   return systemProvider.valueForSymbol(symbolName);
   }
};

String executionMode =
System.getProperty(SymbolConstants.EXECUTION_MODE, "production");

TapestryAppInitializer appInitializer = new
TapestryAppInitializer(logger, provider, filterName, executionMode);

Re: T5 Embedded Components

[Kristian Marinkovic]

Hi,

first remove the id parameter from the @Component annotation; this is
only needed if the field name in the java class is different from the
t:id attribute in the template.

second because you already defined your component in the template you
don't have to declare it in your java class; so you should remove the
TextField fields from your java class; if you still want to access the
component from within java use the @InjectComponent annotation

Re: Problems integrating backbone.js with T5.3.6

[Kristian Marinkovic]

i knew that would come :)  i 'm watching the progress closely; it'll
be a great leap forward in developing js heavy applications.

sometimes there is an easier solution... i just added window._ = T5._
into my copy of backbone.js. i think i was looking to hard to add it
without modifying the original file and using the JavascriptSupport
service for that purpose.

thank you

Problems integrating backbone.js with T5.3.6

[Kristian Marinkovic]

Hi,

i need some advice on how to properly integrate backbone.js in my T5
application.

Adding backbone.js with the @Import annotation results in an console
error because it can't find the global underscore object _. The reason
for that is the mapping of underscore to the T5 namespace in
t5-core.js. When i tried to replace the core javascript stack i
realized that it was already overridden by tapestry5-jquery. My quick
workaround is to add the assets underscore.js and backbone.js manually
using JavascriptSupport; this way i can control the order and _ is
initialized globally again, but underscore is included twice in my
pages.

void afterRender()
{
jsSupport.importJavaScriptLibrary(underscore);
jsSupport.importJavaScriptLibrary(backbone);
}

How could i solve this problem differently? Is anyone using T5 with
backbone already? I'd be interested how the view templates are
handled.

g,
Kris

Re: Displaying UploadedFile in the browser

[Kristian Marinkovic]

Hi,

i just implemented an ajax upload using the AjaxUpload component from
the tapestry5-jquery project. And i had to dive deeper into the
documentation and code of the JS file-uploader component used by the
AjaxUpload.

There are examples in the documentation that almost solve your needs:

Re: Why ActionLink Click is not working?

Hi,

check the value of the context; if it is not set (null) only
onActionFromPlay() will be called; use the EventContext if you want to
catch this use case;

Re: Tapestry-Portlet status?

I think you have to answer this question yourself by checking if your

developed. there is even a mention of Typestry 5.4-alpha in the
readme.

Re: How to have every second value in the t:loop different

[Kristian Marinkovic]

it would be easier to give you an advice if you'd outline the problem
you are having a little more.

but if you ask me i'd put a delegate inside the loop and let the "to"
binding decide what component/block to render. i use this approach to
render a list of "item" (types) that may have completely different
representations.










as always it depends on what you wanna achieve

open the pom.xml of your main application in the eclipse pom editor
and switch to the dependency tab. there you can see all the direct and
transitive dependencies. and do a clean install of all your modules..
or parent project.

How do i trigger a zone update in the parent component or page?

[Kristian Marinkovic]

Hi,

i have a loop in my page that renders some "rows" whereas each row is
a zone component. Each row represents some special data type that has
different properties when edited. Because i don't know in advance how
many data types will be supported (and i want to stay as flexible as
possible) i just return an instance of the data type in my event
handler method and contribute a data type specific
ComponentEventResultProcessor to the
AjaxComponentEventResultProcessor. There i use a name convention to
identify the page and component that is suited to render a specific
form for the specific data type and eventually return the component
for rendering. The benefit is that i can drop in new modules later to
support new data types without changing the existing page.

The problem i'm having is that i was not able to figure out how to
trigger a zone update of the very same row after i save or cancel the
data type specific form component. after rendering the edit component
i lost the zoneid that was associated with the edit link.

Does anyone have an idea how to solve this? Do i have to persist the
generated zoneId somehow to call some JS function manually?

kris

Hi,
Which inject annotation are you using? Chances are that you use the javax

PlasticClass in my transformer where i can e.g. assert that the class
under test has only one method. But if i instantiate a PlasticManager

}
};

@Test

{
PlasticManager m = new PlasticManager();

m.createClass(ClassUnderTest.class, transformer);

Re: IllegalAccessError in IoC

[Kristian Marinkovic]

Hi Peter, 

we do have the same problem here. 

there are two solutions we use to circumvent this problem: 

1) keep your modules (projects) closed; Tapestry 5.2 will only create 
proxies for services without a interface only if it can find the class 
file in the local filesytem (not in jar file)
2) create a patched tapestry 5.2.5 version that does not create proxies 
for services without a interface:

 AbstractConfigurationImpl -> if (contributionType.isInterface() && 
InternalUtils.isLocalFile(clazz))

remove the isLocalFile part; it is not possible to make it configurable 
via a SymbolSource due to recursions.

Betreff:IllegalAccessError in IoC



Hi Howard et al,

We are using Tapestry 5 IoC in all our applications (both standalone and 
web), and have a very sizeable IoC code base. We have tried a couple of 
times now to upgrade it from 5.1 and 5.2.4, but it seems backwards 
compatibility is broken... The problem we are stuck on now is whenever a 
non-public method is called from within a service we are getting the 
dreaded IllegalAccessError. I have not dug very deep into Tapestrys 
internals to figure out why this is happening yet, but I am certain that 
in Tapestry 5.1 this is not the case. 

You might suggest to simply change the scope of these methods and classes 
but we can't easily re-factor our library modules because of the sheer 
scale, and even if it were an option, and we did consider it for a time, 
these errors produce runtime exceptions, which makes it is very difficult 
to find every occurrence in the code, so for us to change the scope for 
our entire IoC codebase is not a practical solution. This seems like a big 
change from 5.1, and is a real blocker for us, I would greatly appreciate 
any assistance.

Thanks,
Peter

Re: Components communication with nested components

[Kristian Marinkovic]

there are two phases in tapestry: the action phase and the render phase. 
for every phase you have to set your environmental services explicitly. 

i often have services that use the ApplicationStateManager service 
directly to access the persisted data, so my components are only aware of 
the service interface. this way i can reload the data whenever i need it 
lazily without coupling the components to my data objects. i hope this 
gives you some ideas.

I am also using @Environmental but it is not availiable at all times. e.g.
when the nested component contains a form and that form is submitted... So
in order to deal with it I use @Persist, first time around and on form
submission I use the persisted value as the environment does not contain 
the
context...

What i was asking is, whether what I am doing is the way to go or there is
any other alternative.

Re: Components communication with nested components

[Kristian Marinkovic]

Declaring all possible values as parameters leads to high coupling. Just 
imagine declaring the parameters in a hierarchy of 5 components just to 
have it.

I'd use Environmental services to pass data between different component 
hierarchies. You can also apply the MVC pattern: create a service (thread 
scoped service or SSO) that acts as the model that the components can use 
to pull data from it. the service interface acts as the contract between 
component and model

hi thiage, 

you're right HttpSessionActivationListener is another possibility :) 

i dont recreate the registry in my HttpSessionListener, i just reuse the

My TapestryListener snippet (could be a filter):

public class TapestryListener implements ServletContextListener
{
public static final String REGISTRY_CONTEXT_NAME = 
"org.apache.tapestry5.application-registry";

public void contextInitialized(ServletContextEvent sce)
{
 
  // same code as in TapestryFilter

registry = appInitializer.createRegistry();

  // set registry in context
context.setAttribute(REGISTRY_CONTEXT_NAME, registry);
...
  // same code as in TapestryFilter
}
}

My HttpSessionListener:

public final class MyHttpSessionListener implements HttpSessionListener
{
...
public void sessionDestroyed(HttpSessionEvent event)
{
HttpSession httpSession = event.getSession();
... 
Registry registry = (Registry) 
httpSession.getServletContext().getAttribute(TapestryListener.
REGISTRY_CONTEXT_NAME);
 
if(registry == null)
throw new RuntimeException("No Tapestry registry 
found. Please check that TapestryListener or -Filter is added as

My approach was to use a RequestFilter to put in the session an object 
that implements HttpSessionActivationListener. It will be notified when 
the session is created and when its destroyed. No need to create the 
Registry manually. :)

What I 'd like to do is to have something like filter.set
AlwaysUseDefaultTargetUrl(true) in my own AppModule as a contribution


Here, for example is another build method from the same library module,
which uses that object:

@Marker(SpringSecurityServices.class)

Exception {

I 'd need some advice on how to "contribute" and set that property to the
required value in my AppModule, I guess that in the 
tapestry-spring-security
site they say something about overriding values using contributeAlias, but
as I 'ver read that this type of contribution is going to be deprecated on
5.3 I didn't try that way yet.

hope I was clear,

thanks as usual...

Re: Question on Tapesry Services IoC

hi nicloas,

you could use a builder method to decouple tapestry ioc from 3rd party 
libraries/constructors

public SomethingManager buildSomethinManager(Map<> map, ...)
{
 return new SomethingManger(map, ... );
}

public void contributeSomethingManager(MappedConfiguration<> map)
{}

Thanks Josh,

sorry for my verbosity

So in order to use contributions to a Service (SomethingManager) through a
MappedConfiguration,

this SomethingManager should have a constructor that receives the
corresponding Map, and tapestry will inject the contributed
MappedConfiguration into it?

ok i got it..., tomorrow  I m going to test it on code.., the thing is 
that
in my case SomethingManager is a 3rd party class 
(tapestry-spring-security)
but i think i can handle it with this information.

thanks for the concept.

Do you know why will Alias Contributions be deprecated? I guess that what
you explained me will be the defacto way of contributing and overriding
contributions?

thanks again and cheers

Re: Actionlinks with the same t:id

i guess you are using a loop to generate a unordered list. 
just place the eventlink into the loop and everything should be fine :)

Hi Kris,

Thanks for the response. Using EventLink I need to have:

private EventLink menuItem1, menuItem2, menuItem3

with t:id="menuItem1" etc in the tml. So still a declaration for each
link in java and a different t:id each time but yes it does mean only
one handler method.

Cheers

Use a EventLink instead and define a custom event.

@Component(parameters= {"event=menu", "context=menuContext"}
private EventLink link;


somewhere else (a parent component):

onMenu()
{}

The t:ids within a component/page have to be unique.

Hi,

I have a menu, with 5 to 10 links, each of which I'd like to be an
actionlink to trigger a zone update. 

I'd like to have just one event handler for the menu, something like:


public Object onActionFromMenu(int context) {
 
... get new results per the context...
 
   return resultsZone.getBody();
}


with my menu like:



  ...


  ...

...


However Tapestry complains, saying that t:id should be unique. If t:id
has to be unique, that means I have to have separate event handlers for
each menu item, which is a little verbose. 

Is there a way of having multiple actionlinks in a page, each triggering
the same event handler? This is also useful if I want to have the same
link more than once in the page.

Thanks

Richard.

Re: dynamic component id?

[Kristian Marinkovic]

i guess it is about the dynamically generated id of the html element ... 
the component should implement the interface ClientElement.
If it does you can call the method getClientId to obtain the id that is 
used in the generated html.

Re: contribute mystery

Hi Jens, 

the contribute methods are used for configuration... therefore there are 
only executed once on startup (... or on lazy load)
once your dispatcher is in place only your dispatcher will be called.

please re-read the tapestry-ioc documentation.

Betreff:contribute mystery



Hi,
 
I’m having some mystery going on when contributing a dispatcher. The 
dispatcher is always instantiated (according to the logs), but it’s used 
only sometimes. In some cases, when I start jetty (or tomcat), the 
dispatcher is used and then consequently it’s always used. But after a 
restart it’s not used, though I haven’t changed anything in the code.
 
Most puzzling to me: I’ve inserted 2 calls to System.out.println() in the 
contribute-method – and voila, the dispatcher is always used. As soon as I 
comment the two lines, it’s again like described above. See code below 
(this is T5.1).
 
Any help is much appreciated, no idea, where to look at.
 
 
public static void contributeMasterDispatcher(
OrderedConfiguration dispatchers,
PageRenderRequestHandler renderer,
AuthenticationService auth,
Sitemap sitemap,
@Inject @Symbol ("loginPage") String loginPage) {

Dispatcher authorizationDispatcher = new 
AuthorizationDispatcher(
   renderer,
   auth,
   sitemap,
   loginPage);

//System.out.println("x Dispatcher initialized");

dispatchers.add("AuthorizationDispatcher", 
authorizationDispatcher, "after:ComponentEvent", "before:PageRenderer");

//System.out.println("xx Dispatcher contributed");  
}
 
 
Many thanks
Jens

move your DisplayContentItemStyle to a package that is not within a pages, 
components or mixins package. eg. services

T5 loads all classes in the before mentioned packages for enhancement with 
another classloader. that's why your class (enum) cant be found.

Re: Dynamically loading a component

[Kristian Marinkovic]

hi omar, 

this is not as horrible as it sounds ... testing gets a lot easier

i have a fairly big T5 application with many modules. within this 
application i have many master - detail views where the detail view 
depends on the type of object within the master list and those types can 
be deployed as needed. ie. if i also deploy my order module my master view 
might show some order entry and if i dont deploy it it wont show up. if i 
click on this entry i want to be directed to a order specific page that is 
defined in another (web) module. therefore i created a service that 
contains a contribution of pages to the specific detail view which is used 
to render / create the appropriate links. 

i also have a BlockService (...Registry) where i can contribute blocks 
that should be reused in multiple pages and modules. 

so you always know in advance what you are gonna render. even the possible 
combinations.

for more details take a look at the BeanEditor implementation.

This is horrible news since I have no way of knowing the components that 
needs to be called at design time (other wise I would use a ).

There is no magic that can be done to achieve this at all? Even if I have 
to use the internal services.

Thanks for your quick response.

unless you pass it to a Delegate or return it to update a Zone. You cannot 
instantiate components in Java code, as Tapestry is static structure, 
dynamic behavior (including rendering). Take a look at 
http://tapestry.apache.org/tapestry5.1/cookbook/switch.html. It shows you 
how to render blocks dynamically, but the same approach can be used for 
components as well. You'll use @InjectComponent to get access in your Java 
code to the component instances declared in templates.

Re: T5 Internet Browser Detection?

[Kristian Marinkovic]

you'd have to implement a HttpServletRequestFilter or better a Dispatcher 
that analyzes the http headers and redirects to other pages or sets some 
global state that is used during page rendering. A Dispatcher is more 
convenient as you can use all the tapestry services and don't have to use 
the servlet api directly.

Is it possible that tapestry can detect web browser?

I already implement it using JQuery.
Using

script type="text/javascript">
$(document).ready(function(){

if($.browser.msie)
{
if($.browser.version == 4.0)
{
window.location = "http://www.google.com";; 
alert("Please install the latest IE Browser!");
}
}
});


But i want to use Tapestry so that it can return into another page.

Is this possible?

Any ideas? ^_^.

Re: Redirect when session is destroyed

[Kristian Marinkovic]

you can't redirect from a SessionListener as it is called by the servlet 
container and does not involve any user interaction. 

provide a Dispatcher that checks  whether your AppModule.USER_LOGGED_IN 
attribute is available from the current HttpSession; if it is not redirect 
the current request to any page

when ever session is destroyed, sessionDestroyed() method in

tapestry is automatically called.

can any one tell me how to redirect the browser to a default page ?
if i had response object i could have redirected to some page but that
method doesn't contain response object.

i have added the code for SessionListener class.

public class SessionListener implements HttpSessionListener {
 public void sessionCreated(HttpSessionEvent se) {
 // Do nothing
 }

 public void sessionDestroyed(HttpSessionEvent se) {
 System.out.println(" *  Session is 
destroyed  *  ");
 HttpSession session = se.getSession();
 Principal principal = (Principal)
session.getAttribute(AppModule.USER_LOGGED_IN);
 session.removeAttribute(AppModule.USER_LOGGED_IN);  
 // Do some stuff here...

Re: Is there any way to render the "get" method of form?

hi lutz,

the use of the 'post' method for the form is hardcoded. the easiest way to 
change this is to have some client-side script that rewrites the method 
attribute to 'get'. an alternative you could have a heartbeat that 
rewrites the generated HTML server-side (take a look at the Label 
component for how to use a heartbeat render command)

i use a (JaxWS)HttpServletRequestFilter service to intercept WS calls to

Hi Jim

I evaluated quite a few Java WS stacks and was between CXF and Metro, but 
in the end I chose metro, but to be honest there was very little to choose 
btw the two... so I would suggest those two as the leading Java WS stacks. 
Both support maven and are very complete in terms of how much of the web 
service set of standards they support. 

Metro implements JAXWS 2.1 and JAXB2.2, so if the marketing babble is to 
be trusted its 'meant' to be higher performing and more extensible, but I 
haven't tested that claim yet. In any event it has an impressive array of 
security features. It also ships with the standard glassfish installation, 
which means no server configuration is needed if you go that route, I 
installed it though with Tomcat, it was as easy as executing a script... 
not too hard at all. 

Depending how you wish to approach you applications, you can use 
annotations for the meta programming, and avoid a lot of the messy xml. I 
found it to be really clean and the closest to Microsofts .Net platform 
implementation which is IMHO a very good implementation of Web Services 
...at least more impressive than anything I have seen in the Java 
community, but I feel the gap is closing slowly.

To integrate with Tapestry I simply overrode Tapestry filter... I am not 
aware of any more elegant approach, although I made a few inquiries on 
this list in the past.

Peter

There was the same problem with writing module classes in Scala or Groovy,

Re: [T5]Inject a component not used in a page

[Kristian Marinkovic]

hi thomas,

tapestry 5 follows the "static structure, dynamic behaviour" philoshophy.
essentially this means that you cant use a component that is not declared
anywhere. in your case i'd create a block with the component inside and 
display this block if necessary.

please see the mailing list for more on "static structure, dynamic 
behaviour"
there. you can take a look at the BeanEditor that dynamically creates a 
input field for every field in a POJO. From the outside it appears as if 
the
components are configured dynamically but under the covers it is 
reassembling existing blocks as needed (type, ...)

Re: Tapestry5 template name simplification

[Kristian Marinkovic]

hi sandeep,

the reason to do so is to have prettier URLs.

When developing an application you tend to 
group your pages into logical packages. lets 
assume your application is able to change
Customer and Address objects. So you'll have
a bunch of pages in the respective packages.
Its very common to have a CustomerList and a
AddressList page that diplays the result of a search.
not altering the URL would result in following page
URLs:
address/addresslist/
customer/customerlist/
(funny note: i really had a customer that considered
above urls as invalid or faulty, because of the 
duplication; he expected something like addresslist/)

T5 will recognize this pattern and change these URLs
to:

customer/list

What are the alternatives? You could rename your pages
to List, but then you'll end up with multiple List classes in
different packages. Or you  could add an own UrlRewriteRule
for every list page.

Betreff:Tapestry5 template name simplification




hi,

As per the tapestry5 documentation
"
In certain cases, Tapestry will simplify the the logical name of a page. 
For
example, the page class org.example.pages.address.Create Address will be
given a logical name of "address/Create" (the redundant "Address" is 
removed
as a suffix) "



I wanted to understand, why does tapestry5 take extra pains to do it. Is
there a huge advantage for doing this? 
Any explanation would help because, otherwise it looks confusing to see an
altered URL.

Thanks
Sandeep

Re: JSP custom tag

[Kristian Marinkovic]

Hi, 

T5 is a completley different technology and does not use JSP to render its 
view. 
You could create a JSP tag library that uses T5 to return HTML snippets 
(using 
a StreamResponse) but i don't see any reason to do so. why would you want 
to 
create JSP tags using T5 anyway? 

if you have to migrate an older application you could just configure and 
deploy
another ServletFilter or Servlet that uses Tapestry 5. and migrate the old 
JSP 
pages to tapestry.

Hi there,


Here is my problem, please tell me if I'm missing something or if I've
encountred a bug:

Here are two components definition :

public class MyComponent
{
@Parameter(value = "literal:something")
private String myParam;
}

public class MyExtendedComponent extends MyComponent
{
@Parameter(value = "literal:newThing")

When using MyExtendedComponent, I expected to have myParam set by default 
to
"newThing", but it is still equals to "something".

Any pointers?

Re: Heavy and long background process

[Kristian Marinkovic]

hi massimo, 

i had a similar problem a while back. 

i solved this problem by letting the long running thread
log its current state and failures into a db table (you could
also use a service and store it in memory). all the view 
needs to know is the job id to query the correct state and 
display it with an ajax updater.

the downside is that it is not that simple anymore to cancel
the thread manually... but this was needed in my case.

i guess you should always decouple the view from a long
running process anyways. especially in a web environment
that is stateless by nature.

Hi all,
  I need to process a big chunk on data uploaded from users. The whole
process takes up to 2-4 hours as involve a big change in the database.

I've implemented this as a series of Invokable from ParallelExecutor
and a "controller" service which hold a weak references to the client
responsible for the data submitted.

With a progresiveDisplay I keep the user informed of the progress of
the operation (and possibly of the errors involved), my reference is
kept in a cookie so users could still log out and come back later.

Now the Futures from my Invokables are within a MAP keyed to my
cookie-key and stored in the Service implementation.

May I ask if this solution sound reasonable to you?

I already know this doesn't fit very well in a clustered environment
but it's not a problem right now... perhaps within 6-8 months.

Thanks

Betreff:[Announce] Tapestry5 jQuery integration and 
Tapestry5-ClientResources
Gesendet von:   odiss...@gmail.com



Hey there,

We are glad to introduce "tapestry5-jquery": a jQuery integration
for Tapestry 5! This integration is already available as a maven
artifact. This library fully drop out Prototype, Scriptaculous, Blackbird
and tapestry.js and replace them by jQuery.

We did our best to make this integration as transparent as possible. An
important part of components can still be used as is! We tried to stick 
the
more we can to jQuery philosophy. All code is based on official jQuery
coding style guidelines and on existing plugins.

jQuery for Tapestry 5 has been a long time request from an important part 
of
Tapestry community. There was some discussions about it and Tapestry 5.2
should provide some built in bridges for other JavaScript frameworks
integration, however there is no chance to see that for Tapestry 5.1.x.

Currently, the module is still in snapshot version and we need feedback 
from
users before releasing it. We are looking forward to find bugs (if there 
are
any) and any lack of features... Some (big) choices have been made and as
there is new features, some features that were present with
prototype/scriptaculous are not available anymore.

All source code is available on Github. Don't forget to read the README 
file
for installation instructions and How To:
http://github.com/got5/tapestry5-jquery


This module comes with a bonus module: "tapestry5-clientresources". It's a
small module also for Tapestry 5.1.0.5 that offers the possibility to
changes default JS and CSS included on each pages. When not using Tapestry 
5
default JS stack (prototype, scriptaculous...) it also fix direct calls to
Prototype functions, like already reported
bug TAP5-994 (and fixed in 5.2). Again, check Github for source code and
instructions: http://github.com/got5/tapestry5-clientresources

Of course, we are looking forward to leverage theses modules to Tapestry 
5.2
as soon as this version is released.

Re: session expired error

[Kristian Marinkovic]

it took me some time to realize you're using Tapestry 4 
please add the version number next time.

there are basically two simple ways to influence the session expiration:

1) change the timeout in your web.xml

10


2) create a component, that is placed on every page that performs 
some ajax requests to a hidden page to keep the session active. 
as long as the browser is open the session wont expire.

Re: [T5.1-Hib] Tapestry and Envers - Retrieve user information for auditing

[Kristian Marinkovic]

hi everton,

if you really can't add the RevisionListener programmatically, define a 
public
static field in your listener using the service type, eg. UserInformation.

then define a eagerload service that has the UserInformation injected and 
set the
public static field in your RevisionListener:


public class RevisionListener {
public static  UserInformation userInformation;
}

public class RevisionListenerInitializer {
public RevisionListenerInitializer (UserInformation 
userInformation)
RevisionListener.userInformation = userInformation;
}

consider this solution as the last resort if everything else fails. be 
careful
with this solution as it is considered bad coding style. i had to do this 
for 
hibernate-search too.

Hi,

Has anyone succeeded in integrating Envers (http://www.jboss.org/envers) 
in a T5.1 app, to audit information HttpRequest based?

I succeeded on putting Envers to work, but I'm stuck at this point and I 
would like to know which approaches some people used to achieve that.

The problem is... I just want to use my implementation os RevisionListener 
Interface, and implement the newRevision(revision) method that needs to 
retrieve the user information and store in the 'revision' object. But, 
since that kind of information would only be available by T5 IoC's 
container, I can't use it there - Becase the RevisionListener 
implementation is instantiated by Envers (i guess so) and it's a Singleton 
per EntityManagerFactory.

This is really a big problem for me, and I would appretiate any help.

Thanks!

Re: Suggestion: Add context to loop

hi pierce,

don't you have the same problem if you 
put 10 eventlinks on your page. how do you
distinguish them? either you have 10 different
event links onEventFromC1() or you use the
context onEvent(String id)... or onEvent(AlmostAnyObject obj)
having a loop rendering the 10 eventlinks is
more or less the same.

if your component creates an eventlink
it should also be able to handle it and
therefore provide the corresponding event
handler.

   1. What if the eventlink is nested several layers deep in components? 
Then value has to be passed all the way down...

   2. Now the nested component needs to know about how the value object is 
encoded, which makes the nested component less "generic" and therefore 
less reusable. In my sample, nestedcomponent doesn't know anything at all 
about "value". It doesn't need to! It's job is just to generate a "fancy" 
link. Instead, that knowledge is localized to where loop is used, which 
also happens to be where the event is processed.

Re: Generated links in a loop

[Kristian Marinkovic]

so you want to generate a link in a grid and dependending 
on a parameter have a mixin attached.

you can solve it by using a delegate that is directed to a block 
(or component) that  in one case contains a simple eventlink and
in the other case contains a eventlink with the attached mixin




that's one of the drawbacks you have, when following the static
structure, dynamic behaviour paradigm. you always have to 
have all posibilities defined in advance. and from my point of 
view it's not always that bad.

Hi Kristian,

Reading through what I wrote, I guess I could be clearer, here is more 
detailed explanation.

I create a model that I attach to a component (a type of custom grid), its 
populated with database records... some of the columns in the grid need to 
be links, and I can create the various types of links (event, page, action 
etc.) as I wish... so far this is all straightforward.

Occasionally I need to generate links that have a mixin attached, my links 
are obviously generated in a loop, and on the fly from the database data.

I am not using a markup writer, but I guess that could be the solution... 
only that would mean also writing out the mixins JavaScript, very 
possible, but I would like to avoid it if there is a better way. 

When generating an event link it would be nice to be able to attach an 
'attribute' (thanks for correcting) to specify a mixin, I know of no way 
to do this dynamically when generating links via Tapestry??

Cheers,
Peter
