Yes, that's certainly an option and that's how I've approached the
prototype, but this strategy doesn't work quite as well if you are
releasing to a customer as opposed to developing company's own site where
you typically already have an http server to deploy the Ember bits to. And
if you have to figure out packaging into a .war anyway, then might make
sense to use a similar setup for development as well. In any case, thanks
for the advice. I bet the framework has changed quite a bit in your two
years. I wonder if your experience has been a positive one and if there are
any "I wish I had known this before we started" tidbits you could share.

@Ivano - if popularity was a measure, we'd all be still using Struts
instead of Tapestry, wouldn't we? Convention over configuration is one
thing, but the article you linked to is a fairly well balanced in my
opinion. For me, the biggest things to like in Ember is it's router, clean
urls, cleaner/simpler concepts and performance.

[Andreas Andreou]

Kalle,
After having worked for more almost 2 years on (mostly) ember,
my advice would be to completely decouple (if possible) the projects.

Move ember on its own, make use of the improving cli plugins for developing,
building and deploying. I'm still on a yeoman created grunt setup, so that
could
also work for you.

Just throw in some cors headers on the tapestry side and you'll be able to
live
code against production data

Hi Kalle, I don't know a thing about Ember and Angular but I plan to
learn about javascript frameworks. Hence I don't have an answer for you
but a question instead (of course totally OT on this list).

First link I get from google searching for "ember angular" is

https://www.airpair.com/js/javascript-framework-comparison

that is a very angular partizan article in reality.
Maybe explanation on why is the first result is this contained phrase:

Nonetheless motivation for the article to sponsor Angular seem reasonable.

If you had mentioned before you were trying to show it in a Zone update, we 
would have understood the problem earlier. You can use blocks in non-AJAX 
scenarios too.

In your case, using your own code, not the one from tapestry5-jquery, the check 
for whether the Google Maps is already loaded should be part of your own code. 
Not a good solution.

Ultimately the solution is to use Require.js or a similar solution and let it 
handle the client-side dependencies and ensure the loading order of JavaScript 
files. Tapestry 5.4 supports it out-of-the-box.

Hi Thiago

Yeap, to simplify the problem, the tapestry5-jquery's GMap component has the 
same problem, with the next code the component renders correctly the google map.

Test.tml

Test.java
public class Test  {
public JSONObject getOptions(){
JSONObject json = new JSONObject();
return json;
}
}

With the next code the GMap component does not render correctly the map after 
you click the refresh link (to show the block).

Test2.tml:
refresh





Test2.java:
public class Test2 {

@Inject
private Block blockResults;

Object onActionFromRefresh() {
return blockResults;
}

public JSONObject getOptions(){
JSONObject json = new JSONObject();
return json;
}
}

When you press refresh link the browser (Chrome) javascript console error is: 
"Failed to execute 'write' on 'Document': It isn't possible to write into a 
document from an asynchronously-loaded external script unless it is explicitly 
opened."


Reference: 
tapestry5-jquery's GMap component source code:

This way (which I suggested, I'm sorry), with the external library included in 
setupRender() and your code that uses it included via @Import, the two JS files 
are included in the wrong order, because @Import is processed before 
setupRender(). Please try this:

@Inject
@Path("classpath:mx/kka/msurvey/web/view/components/maps/googlemaps.js")
private Asset myCode;

public void setupRender() {

javaScriptSupport.importJavaScriptLibrary("https://maps.googleapis.com/maps/api/js?v=3.exp";);
javaScriptSupport.importJavaScriptLibrary(myCode);
)

This will guarantee your code will be included after the Google Maps API.

The component being inside a block (you mean ?) shouldn't make a 
difference. How are you rendering this block?

Hi Thiago, thank you for your answer :)
I'm using Tapestry 5.3.7

> Where's your JavaScript?
For google maps, you have to access the javascript library from a URL, so my 
javascript is inside the url: "https://maps.googleapis.com/maps/api/js?v=3.exp";

> How are you including it?

public class GMapShow {
@Inject
private JavaScriptSupport javaScriptSupport;

public void setupRender() {

javaScriptSupport.importJavaScriptLibrary("https://maps.googleapis.com/maps/api/js?v=3.exp";);
}
}

Testing it, I have created a file (googlemaps.js) with the content of the url: 
"https://maps.googleapis.com/maps/api/js?v=3.exp"; and included it inside 
component:
@Import(library = 
"classpath:mx/kka/msurvey/web/view/components/maps/googlemaps.js")
public class GMapShow {
}

But the result is the same, the map is rendered correctly if the component is 
outside a block but if the component is inside a block, the map is not renderer.

I suppose the javascript inside 
"https://maps.googleapis.com/maps/api/js?v=3.exp"; is loading another javascript 
files and maybe the component is rendered before all all javascript libraries 
are loaded. 
The javascript has snipets that looks like:

getScript("https://maps.gstatic.com/maps-api-v3/api/js/18/5/intl/es_ALL/main.js";);
apiLoad([0.00999776482582,[[["https://mts0.googleapis.com/vt?lyrs=m@27500\u0026src=api\u0026hl=es-ES\u0026","https://mts1.googleapis.com

Hi!

Thanks for being more specific. :) We want to help, but it's quite hard

 I'm developing a Tapestry component (GMapShow) that renders a google  
map. If I include the google maps javascript library directly in this  
component, the map is not render if the component is inside a block, so  
I need to include the library BEFORE the block (with the GMapShow  
component) is rendered.


So, I have created a component to only include the Google Maps library:
public class ImportGMapLib {

@Inject
private JavaScriptSupport javaScriptSupport;

public void beginRender() {

javaScriptSupport.importJavaScriptLibrary("https://maps.googleapis.com/maps/api/js?v=3.exp";);
}
}


By the way, from T5.4 on, you can use https://, http:// and //: in @Import.

Where's your JavaScript? How are you including it? That's probably the  
source of your problem.
If you put your JavaScript code inside a .js file and included using  
@Import or JavaScriptSupport.importJavaScriptLibrary(), your code would be  
automatically included after the library you're using.


That's why we ask people more information and snippets of code when asking  
help: the original question in the subject of the message (how can I  
validate if a script is present), which, by the way, is  
JavaScript-specific, not Tapestry-specific, wouldn't need to be asked.

I need to validate from GMapEdit component if the javascript library 
"https://maps.googleapis.com/maps/api/js?v=3.exp"; was imported, or validate 
inside GMapEdit if the ImportGMapLib component was invoked inside Test.tml.

Re: T5 Tynamo RestEasy, discovering all rest resources and paths

[Alejandro Scandroli]

Hi Daniel

Take a look at RESTEasy's JSAPIWriter [1] and how it was integrated
with tapestry-resteasy [2]
I think you will find everything you need in there.

If you need even more discoverability than that I'd recommend to use
something like Swagger [3]

1: 
https://svn.code.sf.net/p/resteasy/svn/trunk/jaxrs/resteasy-jsapi/src/main/java/org/jboss/resteasy/jsapi/JSAPIWriter.java
2: 
http://svn.codehaus.org/tynamo/trunk/tapestry-resteasy/src/main/java/org/tynamo/resteasy/JSAPIRequestFilter.java
3: http://jira.codehaus.org/browse/TYNAMO-231 ;-)

Cheers.
Alejandro.

Re: T5 IOC Integration Questions

[Martin Kersten]

Norman, I implemented something I called Invoker lately. It was quite easy
to do field injection and calling methods where you inject all parameters.
The mixed part was quite difficult though (provide some parameters and
inject the others). Also be aware of that the ordering of methods is not
guaranteed in any way using JDK 7 192 and above (getDeclaredMethods and
getMethods along with getConstructors now return methods in random order).
I fixed the issue by using ASM and visit each method in the order they are
stored within the class file (which is the exact order you define it in the
java file).

So beside this if you are doing invocation and injection on fields and
methods go ahead. This wont take more then an hour at most. If you need
additional help, just ask. You can even invoke and create private classes /
constructors and methods which comes quite handy in case of writing test
cases.


Cheers,

Martin (Kersten)

Unless there's some setter we could call through injection, I don't think

I strongly believe that Dmitry's suggestion is the simplest and most
efficient so far, thanks a lot for that :)

This would send an ajax request acceptable by tapestry:
ajax = new XMLHttpRequest();
ajax.open("POST", "http://localhost:8080/index:myevent/0/0/0";, true);
ajax.setRequestHeader("X-Requested-With", "XMLHttpRequest"); //This is
necessary
ajax.send(null);

Thank you all :)

Re: [t5] Is it possible to return a component's generated HTML ?

[Dmitry Gusev]

If you only need to get HTML on the client and not on the server-side,
then you may just use Tapestry's built-in logic for handling AJAX requests.

On the server side create eventLink:

Link link = resources.createEventLink(eventType, contextValues);
return link.toAbsoluteURI();

Pass this link to client side during rendering and when needed do the AJAX
calls using, say, jQuery.ajax.

You may handle ajax request on the server side the same way I wrote in my
example above --
return block from event handler or use ajaxResponseRenderer.addRender().
On the client-side response will be the same JSON and you may extract
content from it.

Note that in both cases it is possible to render multiple blocks by one
request -- this is if you call
ajaxResponseRenderer.addRender() multiple times.

Re: [t5] Is it possible to return a component's generated HTML ?

[Dmitry Gusev]

The entry point is:

String rawAddress = renderer.render(new RenderEvent(
"internal/companyblocks", "companyAddress", company));


You tell here that onCompanyAddress method (or method with
@Event("companyAddress")) should be invoked on the internal/companyblocks page
class and if that method returns a Block - it will be rendered to a string.
company - is a parameter to that method that you may use to initialize
rendering context for the block.
You can also not return Block from the method by just addRenderer:

ajaxResponseRenderer.addRender(addressBlockZone);

And the addressBlockZone will be rendered to as string in this case.

Resulting string will be serialized json object, so you can inspect its
structure and take the content you want like:

String htmlAddress = new JSONObject(rawAddress).getString("content");

Re: [t5] Is it possible to return a component's generated HTML ?

[Lance Java]

I think I need to understand how it's going to work before I go any further.



Here's one approach

1. The browser makes a request to the "other" webapp

2. The other webapp makes request(s) to the tapestry app

3. The other webapp merges it's own html with the tapestry html to create a
page

4. The page is returned to the user



Here's another approach

1. The browser makes a request to the "other" webapp

2. The other webapp returns a page with some empty divs

3. Some javascript runs on page load

4. The browser makes requests to the tapestry app

5. The tapestry app returns responses to the browser

6. Some javascript in the browser updates the innerHTML of some div's



In both approaches, you are going to be fighting an uphill battle if you
want to handle javascript and eventlink / actionlinks in your tapestry
components. If you simply want to render html fragments, without links or
javascript we might be able to help.

Re: [t5] Is it possible to return a component's generated HTML ?

[Muhammad Gelbana]

Honestly, I can't figure out anything from these 2 resources ! It all looks
so complicated to me.

@Dmitry
What is the entry point of your code ? When an ajaxrequest is sent to my
application, doesn't it reach your "CompanyBlocks" page ? Then when does
all the other services begin working ?!

@Lanve
And I thought Dimitry's code was complicated :D
Your code was even harder to look at, I also can't understand the entry
point and the flow of data starting when I receive an ajax request till I
respond with a string representation of a component's template file.

[Lance Java]

I'm not 100% sure what your implementation will be but I've done some work
in this area.

Take a look at PDFLink.getFoAsString() where I convert a RenderCommand to a
String of markup (XML in the example)

http://tapestry-stitch.uklance.cloudbees.net/pdflinkdemo

Also, take a look at this wiki entry

http://wiki.apache.org/tapestry/Tapestry5HowToGetAnHTMLStringFromARenderCommandParameter

Note that a Block can be type coerced to a RenderCommand

Re: [t5] Is it possible to return a component's generated HTML ?

[Dmitry Gusev]

You can put your component to a block and render this block.

Have a look at this thread:

Re: T5 and AppEngine 1.7.3 dev server IllegalStateException

[Alex Kotchnev]

Alright - I'm not entirely sure if anyone will find any use for this, but I
implemented the approach suggested by Lance (thank you Lance!) and pushed
the code into BitBucket : https://bitbucket.org/akochnev/tap5-gae-utils

The project wiki explains how to use it, but in short, just include the
module either as a @SubModule or as a module in your Development
configuration.

Now my application runs just fine using the official GAE Maven plugin w/
version 1.8.0. Sweet !

Cheers -

Re: T5 and AppEngine 1.7.3 dev server IllegalStateException

[Lance Java]

A much better option is to fix the bug with a RequestFilter. Wrap the
response in a custom implementation that sets a flag to true when
redirect() is called and returns the correct value in isComitted()

Re: T5 and AppEngine 1.7.3 dev server IllegalStateException

[Alex Kotchnev]

Just out of curiosity - this exception is thrown by Tapestry itself;
however, since it's just a "sanity check" and it only happens on the Dev
server , is there a way to disable this filter using Tapestry IoC ?

org.apache.tapestry5.internal.services.ImmediateActionRenderResponseF
ilter.handle(ImmediateActionRenderResponseFilter.java:63)

I can certainly keep plugging along w/ GAE 1.7.1 ( I don't have a reason to
upgrade); however, it would be nice if things could just work w/ just a
little tweaks.

Re: [T5 5.3.6] Dead Lock while initializing tapestry

[mailingl...@j-b-s.de]

Sorry I do not understand your response. From the stacktrace T5 is building 
your service. In the constructor of the service currently created you are 
spawning a new thread which again needs services from the T5 app in the run 
method, right?

Can't you defer thread creation to a method in your module class annotated by 
@Startup
?

Re: [T5 5.3.6] Dead Lock while initializing tapestry

[Arunas F]

No, not at all. New Thread is spawned at some moment while initializing 
T5 app. And there is nothing special about a code:



new Thread(new Runnable() {

@Override
public void run() {
if (logger.isDebugEnabled()) logger.debug(etlName + " 
initializing... ");


try {

for (EtlAbstractJob job : jobs.getJobs()) {
job.initialize();
}

} catch (EtlJobException e) {
logger.error(e.toString());
e.printStackTrace();
}

if (logger.isDebugEnabled()) logger.debug(etlName + " 
finished initialization... ");

}

}).start();


And in the code  at line "job.initialize();" the var job are T5 IOC 
services and these services depend on MongoDB service at some deeper level.


public class ReportStorageImpl implements ReportStorage {

.

private MongoDB mongoDB;

public ReportStorageImpl(MongoDB mongoDB) {
this.mongoDB = mongoDB;
}

..

@Override
public MongoDB getMongoDB() {
return mongoDB;
}
}

About MongoDB also nothing special. The module is taken from 
https://github.com/mlusetti/tapestry-mongodb-core (look at earlier 
revisions).

Re: [T5] Avoid logs in error for wrong urls and missing components ?

[Nicolas Bouillon]

Thanks for your thoughts, and that leads me to the following suggestion to
resolve my problem:

I've already contributed a custom RequestExceptionHandler using
binder.bind(RequestExceptionHandler.class,
CustomRequestExceptionHandler.class)
  .withId("CustomRequestExceptionHandler");

That is this service which is responsible of my log error message
(org.apache.tapestry5.internal.services.DefaultRequestExceptionHandler#handleRequestException).

In my Custom RequestExceptionHandler, I could check the user agent to match
against bots, and then instead of rendering the exception page, give them a
404 response code so they could stop crawling the page (and me skipping
logger.error at the top of the handleRequestException method).

Best regards.

Re: [T5] Avoid logs in error for wrong urls and missing components ?

[Muhammad Gelbana]

When you create a tapestry project using maven's archtype, it creates the
below request filter (slightly modified) to log how much time each request
consumed.

// Service building
public RequestFilter buildTimingFilter(final Logger log) {
return new RequestFilter() {
@Override
public boolean service(Request request, Response response,
RequestHandler handler) throws IOException {
long startTime = System.currentTimeMillis();
try {
// The responsibility of a filter is to invoke the
corresponding method
// in the handler. When you chain multiple filters
together, each filter
// received a handler that is a bridge to the next filter.
return handler.service(request, response);
} finally {
long elapsed = System.currentTimeMillis() - startTime;
if (TimeUnit.MILLISECONDS.toSeconds(elapsed) >= 10) {
log.warn(String.format("Request time: %d ms", elapsed));
 }
}
}
};
}

// Service contribution
public void contributeRequestHandler(OrderedConfiguration
configuration, @Local RequestFilter filter) {
// Each contribution to an ordered configuration has a name, When
necessary, you may
// set constraints to precisely control the invocation order of the
contributed filter
// within the pipeline.
configuration.add("Timing", filter);
}

>From there, if you find a pattern for requests coming from bots, you can
drop these requests if that suits you. This way these bots will also learn
that the links they are requesting doesn't exists anymore and will
eventually stop bothering you, if they are smart enough !

You seem to be receiving an instance of a page or component or mixin in a  
service. Never do that. As Tapestry changes that classes in a different  
classpath when they're loaded, non-transformed classes (like your service)  
only see the original, non-transformed page, component or mixin.


The solution is to create an interface, make the page, component or mixin  
implement it and then use the new interface as the parameter in your  
service.

It's a little weird to talk in Tapestry about embedded components because

How can I pass the Text field component to the SimpleTextField Component  
to avoid the above error or is there a different approach I should be  
taking?


Tapestry components are meant to be used as black boxes, so you're not  
supposed to refer to anything declared inside a component. If you really  
need to get the component inside the component, something you should  
avoid, create a getter in the component that has the component you want.

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: T5 and AppEngine 1.7.3 dev server IllegalStateException

[Alex Kotchnev]

Correction, this issue seems to have shown up w/ GAE 1.7.2 instead of 1.7.3
. Reverting the appengine sdk to version 1.7.1.1 resolves the issue whereas
staying w/ 1.7.2 does not.

Re: t5: clear cookie when browser closes

[sub]

I also have the problem to set a so called "session cookie" with tapestry.

org.apache.tapestry5.services.Cookies Interface is missing (among others)
this method:

public void writeCookieValue(String name, String value, String path, int
maxAge)

So if you want to write a Cookie with a custom path and also a custom maxAge
you can't. The workaround that I used so far is 

public void writeCookieValue(String name, String value, String path)

and set the maxAge global via AppModule:

configuration.add(SymbolConstants.COOKIE_MAX_AGE, "720");


But now I want to switch from the persistent cookie to a session cookie, so
I changed the line to:
configuration.add(SymbolConstants.COOKIE_MAX_AGE, "-1");

which results in this exception:

Exception constructing service 'Cookies': Coercion of -1 to type
org.apache.tapestry5.ioc.util.TimeInterval (via String -->
org.apache.tapestry5.ioc.util.TimeInterval) failed: Unexpected string '-'
(in time interval '-1').

What other options do I have?

Thx
Tim

Re: T5 and JS UI Frameworks

[Lenny Primak]

Sounds like vaadin. We use smartgwt in our apps within tapestry. It works great 
along with an integration layer in the FlowLogix library.

Many UI frameworks work best with restful web services that return json
responses. You might find tapestry-resteasy a good fit
(http://tynamo.org/tapestry-resteasy+guide)

Re: t5: adding http header

[netdawg]

Thanks!! 

Yep, even though java -version on command line shows 1.6, the Eclipse (right
click) project --> properties --> java compiler shows using "JDK 1.5
compliance".  Changed that to 1.6 and sure enough no complaints on the
@Override annotation anymore.

And thanks for that typo catch  ;-).  

In fact, off-topic, but in case anyone would  like to use this code, the
whole expires date can be made redundant by using max-age in the HTTP
request header, per RFC 2616 14.21.  

response.setHeader(CACHE_CTRL, "no-cache, no-store, max-age=0,
must-revalidate"); 

Also see: http://www.mnot.net/blog/2007/05/15/expires_max-age

(this also has a link to an excellent tutorial on caches - must read - basic
message being cache control is probably best handled by web server, if you
can control it,  rather than in your application)

Re: t5: adding http header

If the compiler complained about @Override, you are problem using a
1.5 JDK and Wulf (I assume) was using 1.6.

RE: t5: adding http header

[netdawg]

Wulf:  Why (rather how) the @Override annotation ?  I actually had to remove
it for it work.   

Anyhooo...here is the complete working example (right or wrong, not
sure)...comments welcome...

Step 1.  Created a class in your src/main/java -- SERVICES package - where
you will find AppModule.java already installed by Tapestry.  In my case, I
created a class called RevalidateHTTPHeader 

package org.yourGroupId.yourArtifactId.services;

import java.io.IOException;

import org.apache.tapestry5.services.Request;
import org.apache.tapestry5.services.RequestFilter;
import org.apache.tapestry5.services.RequestHandler;
import org.apache.tapestry5.services.Response;


public class RevalidateHTTPHeader implements RequestFilter 
{

  private static final String CACHE_CTRL = "Cache-Control";
  private static final String EXPIRE_DATE = "Exprires";
 
  public boolean service(Request request, Response response,  RequestHandler
handler) throws IOException 
  { 
response.setHeader(CACHE_CTRL, "no-cache, no-store, must-revalidate"); 
response.setHeader(EXPIRE_DATE, "Sun, 07 Dec 1941  07:55:00 GMT"); 
return handler.service(request, response);   
  }
}


Step 2.  Within AppModule.java, do two things - 

a.  declare the following member variable

RevalidateHTTPHeader nocache = new RevalidateHTTPHeader();

b.  add the following within contributeRequestHandler method:

public void contributeRequestHandler(OrderedConfiguration
configuration,
 @Local
 RequestFilter filter)
{
// Each contribution to an ordered configuration has a name, When
necessary, you may
// set constraints to precisely control the invocation order of the
contributed filter
// within the pipeline.

///
//  ADD the custom nocache HTTP header(s)  
 
   configuration.add("NoCache", nocache);  

   //
  //


configuration.add("Timing", filter);
}

Step 3:   Run Jetty to verify/examine headers - I am using Google Chrome -
which has a free HTTP Headers extension.  
http://localhost:8080/yourArtifactId/[yourPage]

Name   Extension
Content-Encodinggzip
Exprires   Sun, 07 Dec 1941  07:55:00 GMT
Transfer-Encoding  chunked

Content-Type   text/html; charset=utf-8
Cache-Control  no-cache, no-store, must-revalidate

Re: T5 Auto Binding of DAOs

[Dmitry Gusev]

There's a typo in the code snippet, should be:

String className = interfacesPackage.getName() + ".impl." +
intf.getSimpleName() + "Impl";

We need just package name, not its toString() presentation which is
"package com.x.y.z"

Hi there,


Hi!


Tapestry version: 5.3.3

How to catch the exceptions thrown by the event handler?

e.g.:
try {
resources.triggerEvent("anEvent", new Object[]{}, null);
} catch (Exception e) {
logger.error("Error occurred.", e);
form.recordError(e.getMessage());
}


triggerEvent() just triggers the event, it doesn't handle it.


But seems that the catch parts never get executed, T5 just redirects the
request to the exception page.


You can use a global exception page.

I might.. yes.  I don't necessarily need a lot of content, but a paragraph
and a few code snippets for each service would be a fantastic jump-off
point.

One side effect of all Tapestry's injection, reflection-based config and
event binding, and literate APIs, is that the explorability suffers a bit.
 I can't rely on my IDE auto-completing the relevant events on an
interface, I've got to find some relevant documentation.

It's a very powerful thing to know what all your choices are within the IDE.

Re: T5 Auto Binding of DAOs

[Muhammad Gelbana]

I remember tapestry that by searching for implementation classes in the
same package by the same name but suffixed by "Impl". Like "MySvc" as in
interface and "MySvcImpl" as the implementation.

1. When I wan'ted to extract that piece of info from the docs I couldn't
find it ! Is it deprecated ?!
2. The only advantage from the codes listed in this thread is placing the
implementation classes in a sub-package called "impl", correct ?

That would work, but I was thinking more general case. 

This document: 
http://tapestry.apache.org/component-parameters.html#ComponentParameters-bindingparameters
seems to indicate that it should give me "The id of another component within 
the same template", but really gives you the actual component and you can't use 
the dot notation to then access its properties.

Re: T5 template expansion for component

[Dusko Jovanovski]

I don't see why you couldn't customize t:label, it supports informal
parameters, everything you pass as an attribute will be passed down to the
 tag. In the for parameter of t:label you pass the server id of
the component.

Re: T5 template expansion for component

[Howard Lewis Ship]

So you have a CustomLabel component of some kind, right?  What you need is
to pass the Checkbox component as a parameter of type Field, and invoke
Field.getLabel().




And inside CustomLabel.java:

  @Parameter(required=true)
  private Field field;

For extra credit:




And inside CustomLabel.java:

  @Parameter(required=true, defaultPrefix=BindingConstants.COMPONENT)
  private Field field;

Re: T5 and Redis

[Howard Lewis Ship]

I don't know the Redis/Jedis API, but you probably want to close the
connection you open explicitly.

See 
http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/ioc/services/PerthreadManager.html#addThreadCleanupListener(org.apache.tapestry5.ioc.services.ThreadCleanupListener)

I would tend to add a method annotated with @PostConstruct that
injects the PerthreadManager as the place to register the listener,
i.e.,

  @PostConstruct
  public void registerForCleanup(PerthreadManager manager) {
manager.addThreadCleanupListener(new ThreadCleanupListener() { ... });
  }

[Angelo C.]

Jedis has a pool, maybe it can be implemented as Hibernate.

Is there anybody using Redis with T5 and how? Thanks

Re: T5 and Redis

[Lance Java]

You could follow the same pattern as used for a hibernate session. See this
recent thread for how it's done

Re: T5 How can I pass a block to a component?

In Test.tml you could also do:

Re: T5 How can I pass a block to a component?

[iberck]

I found the solution:


.tml:
public class Component1 {

@Parameter
@Property
private Block block1;
}

.java:
contenido bloque: 

Test.tml:


texto bloque uno

Hi there,


Hi!


is there any support to draw graphics in Tapestry?
I'm looking for some component that offers some standard Java Graphics2D
object and renders this as some possible web-graphics at the client,
e.g. HTML5 canvas with Javascript. Is there any such support?


Just use some JavaScript framework/library for that.


Additionally I'd like to be able to update the graphics via Ajax.


You can use a Zone or use some custom JS code for it.
