Re: dwr java chat demo in t5
Hi, Lance, wow, thank you for pointing me to your project! Integration is more than easy, your example works outofthebox in my browsers. I had to install jetty7 support, seems that jetty6 does not support websockets. What are the disadvantages of websockets compared to ajax? I think not all browsers support websockets? Especially the older versions? But i think that all the major browsers support that in their latest versions? I did read that the t5 team want to integrate push, but did not see how this is scheduled. So i want to go with your project. Thanks again, Lance!

Re: dwr java chat demo in t5
tapestry-cometd is built using the cometd integration in atmosphere. Atmosphere supports a variety of push mechanisms including WebSockets, Server Side Events (SSE), Long-Polling, HTTP Streaming (Forever frame) and JSONP. Out of the box, tapestry-cometd is configured to use org.cometd.websocket.server.WebSocketTransport but this can be configured in your AppModule ( https://github.com/uklance/tapestry-cometd/blob/master/src/main/java/org/lazan/t5/cometd/services/CometdModule.java#L54 ) The supported servers and browsers are listed here: https://github.com/Atmosphere/atmosphere/wiki/Supported-WebServers-and-Browsers Some more docs here https://github.com/Atmosphere/atmosphere https://github.com/Atmosphere/atmosphere/wiki/Getting-started-with-Cometd https://github.com/uklance/tapestry-cometd/wiki/Configuring-the-CometD-Servlet http://cometd.org/
Re: dwr java chat demo in t5
The supported browsers section on the atmosphere page can be ignored as this refers to atmosphere.js which is not used by the cometd integration. Only the supported servers section is relevant. Best to check the cometd docs for supported browsers at www.cometd.org
dwr java chat demo in t5
Hi @all, i was suprised that t5 does not support reverse ajax ;-( googleing around, the only thing mentioned often enough is dwr and i ended here: http://apache-tapestry-mailing-list-archives.1045711.n5.nabble.com/Implement-chat-function-td5606481.html Actually, i want to do the same thing as the threadstarter: A loggedin user can start a one-to-one chat with an admin. The admin can handle multiple chats at the same time... I don't really know if dwr is what i really want and if dwr is the best thing recommended? Or are better solutions out there? So i've tried to integrate the Java Chat with the latest dwr-RC3 from dwr first, but only with partial success. My implementation does not have the same behaviour like the demo: http://directwebremoting.org/dwr-demo/reverseajax/java-chat.html I've put the HTML source (i had to replace the div with an ul) and the Javascript source into a .tml and the Java source into a corresponding java class into my t5 jumpstart project. GOOD: i can see the clients polling: ... [INFO] log.accessLog Incoming request: /dwr/call/plainpoll/ReverseAjax.dwr [INFO] log.accessLog Incoming request: /dwr/call/plainpoll/ReverseAjax.dwr [INFO] log.accessLog Incoming request: /dwr/call/plainpoll/ReverseAjax.dwr [INFO] log.accessLog Incoming request: /dwr/call/plainpoll/ReverseAjax.dwr ... GOOD: the addMessage() Method is called when the button is pressed ok, this is default behaviour GOOD: with opera i first get the expected behaviour: open page in opera and firefox, type opera1 in opera and the message will be displayed in firefox and opera correctly. NOT GOOD: Then i type an opera2 in opera and in opera i see the correct output: ul id=chatlog liopera2/li liopera1/li /ul But in firefox, the first message did not disapear, i get: ul id=chatlog liopera1/li liopera2/li liopera1/li /ul BAD: now i type firefox in firefox and i get in opera: ul id=chatlog liopera2/li liopera1/li lifirefox/li liopera2/li liopera1/li /ul In the firefox browser nothing happens... the textfield is not reset and i still have: liopera1/li liopera2/li liopera1/li BAD: when i now type an opera3 in opera, i get in opera: ul id=chatlog liopera3/li lifirefox/li liopera2/li liopera1/li /ul initially what i did really expected, but before was the wrong output, which is now replaced with the correct output :-) In firefox still everythig is wrong: ul id=chatlog liopera1/li liopera2/li liopera1/li liopera3/li lifirefox/li liopera2/li liopera1/li /ul VERY BAD: i get a lot of: 2013-05-22 22:28:47.976:WARN::header full: java.lang.NullPointerException and: 2013-05-22 22:28:47.976:WARN::header full: java.lang.IllegalStateException: last? and i don't know anything about these message, from where they come and what they mean and how i can trace them Also with chrome i am facing similar issues to firefox. I know the most questions will come, when i want to access tapestryservices later, but when i get these strange behaviour i don't know if dwr is the right thing when i don't get this simple example running. The thing is that i don't really know what the clients are calling. They call the dwr-servlet via the generated .js: return dwr.engine._execute(p._path, 'MyChat', 'addMessage', arguments); but how does dwr response? In the end i must access a t5 service, so the response must be filled with data from the t5 service... At this point i can not imagine how i can encapsulate dwr with t5 and let dwr interact with t5. Informations and examples are more than rare :-( A reverse ajax chat-webapp is not the most extreme case i can imagine :-) Anybody out there with some suggestions?

Re: T5 and AppEngine 1.7.3 dev server IllegalStateException
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 and AppEngine 1.7.3 dev server IllegalStateException
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
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 !

Re: Problem in starting up T5 registry (not web app)
Hi again, this is just for curiosity but maybe some T5Guru has a clear explanation: Do PerThread scoped services needs an interface + implementation ? I am curios because I noticed these different behaviors: I setup a registry using t5 - 3.6, define my Module Class with one service annotated with PerThread Scope. The service depends on other services, and symbols. On my Mac, Everything is working fine, running it using mvn exec:java, and withing eclipse On my Linux (Ubuntu 12.04) virtual machine I git-pulled the very same project and run with the same configurations (startup options, dependencies, etc.). In this case however I got an exception on startup (see below ): As suggested by the exception, I refactored my code such that ServiceDeployer has an interface and an implementation. And everything seems to work just fine. However, I am curios about the different behavior of the same java code on the two machines. -- Alessio = Trace = 2013-05-14 12:35:11,206 [at.ac.tuwien.dsg.cloud.CloudDriver.main()] INFO org.apache.tapestry5.ioc.RegistryBuilder - Adding module definition for class org.apache.tapestry5.ioc.services.TapestryIOCModule 2013-05-14 12:35:11,309 [at.ac.tuwien.dsg.cloud.CloudDriver.main()] INFO org.apache.tapestry5.ioc.RegistryBuilder - Adding module definition for class at.ac.tuwien.dsg.cloud.modules.CloudAppModule 2013-05-14 12:35:11,570 [at.ac.tuwien.dsg.cloud.CloudDriver.main()] INFO at.ac.tuwien.dsg.cloud.services.impl.ConfigurationFileSymbolProvider - Properties read from /home/ubuntu/elasticTest/euca-interface/src/ main/resources/cloud.properties 2013-05-14 12:35:11,570 [at.ac.tuwien.dsg.cloud.CloudDriver.main()] INFO at.ac.tuwien.dsg.cloud.services.impl.ConfigurationFileSymbolProvider - [ch.usi.cloud.controller.eucalyptus.accessKey, ch.usi.cloud.contr oller.eucalyptus.ccPort, ch.usi.cloud.nova.userName, ch.usi.cloud.nova.tenant.id, ch.usi.cloud.nova.tenant.name, ch.usi.cloud.controller.eucalyptus.secretKey, ch.usi.cloud.controller.eucalyptus.ccAddress, ch.us i.cloud.nova.password] 2013-05-14 12:35:11,682 [at.ac.tuwien.dsg.cloud.CloudDriver.main()] ERROR org.apache.tapestry5.ioc.Registry - Error building service proxy for service 'ServiceDeployer' (at at.ac.tuwien.dsg.cloud.modules.CloudA ppModule.buildServiceDeployer(String, String, String, Integer, EucalyptusController, EucaServiceStateDBInterface, CloudInterface) (at CloudAppModule.java:109)): Service scope 'perthread' requires a proxy, but t he service does not have a service interface (necessary to create a proxy).

Problem in starting up T5 registry (not web app)
Hi all,
maybe I have overlook something but I cannot figure out why the registry fails
at startup.
The funny thing is that it worked yesterday and this morning, then it
stopped...
I am using eclispe, m2eclips, and mvn, but also mvn directly from the command
line (I need to run mvn through a SOCKS proxy)
From the exception I see that the problem might not be strictly due to Tapestry
... but maybe someone can help on how to approach/solve this.
Many thanks.

Re: Problem in starting up T5 registry (not web app)
Hi,
I ended up in creating a brand new file called IOCStrings.properties and put
it in the org/apache/tapestry5/ioc/internal.
I filled the file with the content of the same file but taken from the version
number 5.3.5... Apparently in the version 5.3.6 that I downloaded the file is
missing...
I cannot explain how I managed to remove it (if the file was there).
Any suggestion is welcome.

Hi all,
maybe I have overlook something but I cannot figure out why the registry
fails at startup.
The funny thing is that it worked yesterday and this morning, then it
stopped...
I am using eclispe, m2eclips, and mvn, but also mvn directly from the command
line (I need to run mvn through a SOCKS proxy)
From the exception I see that the problem might not be strictly due to
Tapestry ... but maybe someone can help on how to approach/solve this.
Many thanks.

Re: loop pagination - T5 Bootstrap
Still i thank you for inspiration with your gallery component and other components in library. Thanks! Sorry for my previous answer… I didn't realise that this tapestry-bootstrap mixin existed. After looking at the source here: https://github.com/trsvax/tapestry-bootstrap/blob/master/src/main/java/com/trsvax/bootstrap/mixins/Pager.java It seems to me that this mixin does not do 'true' paging since the source is a java.util.List. I realise that the client only sees a page of data at a time. But on the server, the entire List must be loaded into memory which may cause OutOfMemoryErrors for large collections. The GridDataSource (or similar interface that supports serverside paging) is the more scalable solution. Please correct me if I'm wrong… I only had a quick look through the source code.

Re: loop pagination - T5 Bootstrap
It's true the mixin does not support GridDataSource, probably should but it works OK for most things as is. To support really large collections the pagination component would also need to be rewritten since it displays a link per page and that would not work well for thousands of pages. The other thing that got lost in my conversion to Bootstrap 2 was the mixin that allowed infinite scrolling if javascript is enabled. Perhaps it's time for some updates.

Re: basic auth in T5
Come on people - basic authentication is not that old... You can of course you the standard servlet container managed authentication whether you use form or basic authentication but it's not a requirement for basic. You can also use tapestry-security exactly the same way as you otherwise would and configure SecurityFilterChainFactory.basic() filter to authenticate via basic authentication headers.

Re: basic auth in T5
Hi, Thanks for the tip, it is in the servlet level, it will be nice if we can have a simply way to mark a certain route in tapestry5 with http basic authentication, the use case is, an app might have a very rich javascript client, and accessing pages with restful api, if those api can be protected with http basic authentication, development will be easier.

Re: [T5 5.3.6] Dead Lock while initializing tapestry
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
?

[T5 5.3.6] Dead Lock while initializing tapestry
Hi, We are using T5 version 5.3.6. I found that Tapestry runs into a dead lock while building registry (initializing) if I start a new Thread what uses some T5 services. Right now we have disabled multi threading while initializing app. But I would like to know, is it a T5 bug and I should file it into JIRA or this is an expected behavior and it is a T5 limitation. Problem description: If the T5 registry and new Thread tries to create same service (from proxy) simultaneously sometimes you can run into deadlock and T5 app wont initialize. In the stacktrace dump below, you can find that both threads tried to create MongoDB instance and ran into a deadlock. Found one Java-level deadlock: = Thread-10: waiting for ownable synchronizer 0x0007c27e65f0, (a java.util.concurrent.locks.ReentrantReadWriteLock$NonfairSync), which is held by Thread-4 Thread-4: waiting to lock monitor 0x7fdf5b91c658 (object 0x0007eda35c20, a org.apache.tapestry5.ioc.internal.services.JustInTimeObjectCreator), which is held by Thread-10 Java stack information for the threads listed above: === Thread-10: at sun.misc.Unsafe.park(Native Method) - parking to wait for 0x0007c27e65f0 (a java.util.concurrent.locks.ReentrantReadWriteLock$NonfairSync) at java.util.concurrent.locks.LockSupport.park(LockSupport.java:186) at java.util.concurrent.locks.AbstractQueuedSynchronizer.parkAndCheckInterrupt(AbstractQueuedSynchronizer.java:834) at java.util.concurrent.locks.AbstractQueuedSynchronizer.doAcquireShared(AbstractQueuedSynchronizer.java:964) at java.util.concurrent.locks.AbstractQueuedSynchronizer.acquireShared(AbstractQueuedSynchronizer.java:1282) at java.util.concurrent.locks.ReentrantReadWriteLock$ReadLock.lock(ReentrantReadWriteLock.java:731) at org.apache.tapestry5.ioc.internal.util.ConcurrentBarrier.withRead(ConcurrentBarrier.java:75) at org.apache.tapestry5.ioc.internal.ModuleImpl.findOrCreate(ModuleImpl.java:213) at org.apache.tapestry5.ioc.internal.ModuleImpl.getService(ModuleImpl.java:109) at org.apache.tapestry5.ioc.internal.RegistryImpl.getService(RegistryImpl.java:421) at org.apache.tapestry5.ioc.internal.RegistryImpl.getObject(RegistryImpl.java:868) at org.apache.tapestry5.ioc.internal.ObjectLocatorImpl.getObject(ObjectLocatorImpl.java:57) at org.apache.tapestry5.ioc.internal.util.InternalUtils.calculateInjection(InternalUtils.java:257) at org.apache.tapestry5.ioc.internal.util.InternalUtils.access$000(InternalUtils.java:50) at org.apache.tapestry5.ioc.internal.util.InternalUtils$4.invoke(InternalUtils.java:289) at org.apache.tapestry5.ioc.internal.util.InternalUtils$4.invoke(InternalUtils.java:286) at org.apache.tapestry5.ioc.internal.OperationTrackerImpl.invoke(OperationTrackerImpl.java:74) at org.apache.tapestry5.ioc.internal.PerThreadOperationTracker.invoke(PerThreadOperationTracker.java:87) at org.apache.tapestry5.ioc.internal.RegistryImpl.invoke(RegistryImpl.java:1124) at org.apache.tapestry5.ioc.internal.util.InternalUtils.calculateParameters(InternalUtils.java:293) at org.apache.tapestry5.ioc.internal.util.InternalUtils$23.invoke(InternalUtils.java:1488) at org.apache.tapestry5.ioc.internal.util.InternalUtils$23.invoke(InternalUtils.java:1483) at org.apache.tapestry5.ioc.internal.OperationTrackerImpl.invoke(OperationTrackerImpl.java:74) at org.apache.tapestry5.ioc.internal.PerThreadOperationTracker.invoke(PerThreadOperationTracker.java:87) at org.apache.tapestry5.ioc.internal.RegistryImpl.invoke(RegistryImpl.java:1124) at org.apache.tapestry5.ioc.internal.util.InternalUtils.createConstructorConstructionPlan(InternalUtils.java:1480) at org.apache.tapestry5.ioc.internal.ConstructorServiceCreator.getPlan(ConstructorServiceCreator.java:52) at org.apache.tapestry5.ioc.internal.ConstructorServiceCreator.createObject(ConstructorServiceCreator.java:61) at org.apache.tapestry5.ioc.internal.OperationTrackingObjectCreator$1.invoke(OperationTrackingObjectCreator.java:45) at org.apache.tapestry5.ioc.internal.OperationTrackerImpl.invoke(OperationTrackerImpl.java:74) at org.apache.tapestry5.ioc.internal.PerThreadOperationTracker.invoke(PerThreadOperationTracker.java:87) at org.apache.tapestry5.ioc.internal.RegistryImpl.invoke(RegistryImpl.java:1124) at org.apache.tapestry5.ioc.internal.OperationTrackingObjectCreator.createObject(OperationTrackingObjectCreator.java:49) at org.apache.tapestry5.ioc.internal.SingletonServiceLifecycle.createService(SingletonServiceLifecycle.java:29) at org.apache.tapestry5.ioc.internal.LifecycleWrappedServiceCreator.createObject(LifecycleWrappedServiceCreator.java:46

Re: [T5 5.3.6] Dead Lock while initializing tapestry
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).

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(OrderedConfigurationRequestFilter
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 !

RE: what javascript does T5 use
Tapestry5 has been tied to prototype / script.aculo.us since the beginning but this is about to change. Howard has just committed changes to the unreleased 5.4 branch which will make it easy to swap the foundation framework (jquery/prototype/etc). If you want to use jquery today, there is 3rd party library tapestry-jquery which removes prototype from a tapestry application and uses jquery instead. It comes with some jquery-ui based components built in. http://tapestry5-jquery.com/ -- View this message in context: http://tapestry.1045711.n5.nabble.com/what-javascript-does-T5-use-tp5718828p5718830.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

T5 Embedded Components
Embedded components
I have a page (welcome) in which I am looking to use a custom
simpletextfiled component to display numerous text fields (in the future I
envisage simpledate and simple select components, The simpleTextfield
contains numerous other divs, css and other components).
public class Welcome{
@Persist
private String field1,field2,field3;
@Component(id = field1)
private TextField field1Field;
@Component(id = field2)
private TextField field2Field;
@Component(id = field3)
private TextField field2Field;
}
welcome.tml
uses
t:SimpleTextField/
where SimpleTextField.tml is as follows
t:container xmlns:t=http://tapestry.apache.org/schema/tapestry_5_3.xsd;
input t:type=textfield t:id=field1Field t:value=field1Field
label=message:field1Field-label name=field1Field size=35
class=height10Px //div
t:helpText (a custom component for helptext)
/t:container
When I run this I recieved the following error
Embedded component(s) field1Field are defined within component class
com.axa.cao.pages.partner.Welcome (or a super-class of Welcome), but are not
present in the component template
(classpath:com/axa/cao/pages/partner/Welcome.tml).
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?
Thanks in advance.

Re: T5 Embedded Components
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

Suppressing t5 translations
Hello Guys, Today I found issue: https://issues.apache.org/jira/browse/TAP5-2023 Short version is that a specific locale (zh_CN) produces an exception in conjunction with field validators because some messages don't use indexed format parameters. The work-around we thought of until this is fixed in tapestry is to suppress the specific locale (zh_CN) and only allowing local zh. Of course, this means that our texts will be translated but tapestry's messages won't be. We can make do with this at the moment but it does raise the question of whether or not there is any way to overwrite T5s already translated messages? If there is not, can I kindly request this feature because if this had happened with locale de or some other important top-level locale we would be in a very, very bad situation right now.

Re: t5: clear cookie when browser closes
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').

T5 checkbox and validate
I wonder why the component Checkbox doesn't have the parameter validate like
most of the other fields.
I have the following security use case: Even when some fields are not
rendered to UI (or only rendered disabled) because the user doesn't have the
required permission/role, I need to make sure these fields don't get changed
through HTTP Post data manipulation.
A new validator checking the permissions works fine for fields with validate
(for instance a TextField). However, the Checkbox can't be validated.
I think the parameter validate would also be useful for any other
unpredictable reasons.
There was a related topic in 2008:
http://tapestry.1045711.n5.nabble.com/T5-checkbox-component-and-validation-td2420125.html
In T5 the fields RadioGroup and Palette were extended with this parameter:
https://issues.apache.org/jira/browse/TAP5-166
https://issues.apache.org/jira/browse/TAP5-868
Although I managed to solve the scenario the next way, with validate it
would be much simpler.
1) New validatable Checkbox
/**
* Checkbox with validate parameter. (/Note:/ {@link
org.apache.tapestry5.corelib.components.Checkbox} components
* can not be validated.)
*
* @author ferengra
*/
public class ValidatableCheckbox extends AbstractTextField
{
@Inject
private Request request;
@Environmental
private ValidationTracker tracker;
@Override
protected void writeFieldTag(MarkupWriter writer, String value)
{
writer.element(input, type, checkbox,
name, getControlName(),
id, getClientId(),
checked, Boolean.parseBoolean(value) ? checked : null);
}
final void afterRender(MarkupWriter writer)
{
writer.end(); // input
}
@Override
protected void processSubmission(String controlName)
{
super.processSubmission(controlName);
String postedValue = request.getParameter(controlName);
// Record as true or false
tracker.recordInput(this, Boolean.toString(postedValue != null));
}
}
2) Add a new translator.
/**
* Performs boolean translation between server-side and client-side
representations.
*
* @author ferengra
*/
public class BooleanTranslator extends AbstractTranslatorBoolean
{
/**
* Constructor.
*/
public BooleanTranslator()
{
super(boolean, Boolean.class, a-boolean-is-a-boolean);
}
@Override
public void render(Field field, String message, MarkupWriter writer,
FormSupport formSupport)
{
// Does nothing
}
@Override
public Boolean parseClient(Field field, String clientValue, String
message)
{
return on.equalsIgnoreCase(clientValue) ||
Boolean.TRUE.toString().equalsIgnoreCase(clientValue);
}
@Override
public String toClient(Boolean value)
{
return String.valueOf(value);
}
}
3) Add a null field strategy for handling the unchecked checkbox value
/**
* Treats nulls to or from the client as if they were false.
*
* @author ferengra
*/
public class FalseNullFieldStrategy implements NullFieldStrategy
{
@Override
public Object replaceToClient()
{
return Boolean.FALSE;
}
@Override
public String replaceFromClient()
{
return Boolean.FALSE.toString();
}
}
4) Contribute the above two.
public void contributeTranslatorSource(MappedConfigurationClass,
Translatorlt;? translator)
{
translator.add(Boolean.class, new BooleanTranslator());
}
public static void
contributeNullFieldStrategySource(MappedConfigurationString,
NullFieldStrategy configuration)
{
configuration.add(false, new FalseNullFieldStrategy());
}
5) Add the new checkbox with validation and null field strategy.
@SuppressWarnings(unused)
@Component(parameters = {value=dto.valueBoolean
validate=permission=PERMISSION_UPDATE, nulls=false})
private ValidatableCheckbox valueBoolean;

T5 and JS UI Frameworks
Hi Everyone, I'm currently evaluating a proprietary JavaScript UI Framework for use with Tapestry5. This framework works like ExtJS in that rich components are instantiated and placed via JavaScript (basically how you'd do UI programming in Swing). Does anyone here have and experience with using a framework like this together with Tapestry for a larger application? Thanks in advance for any pointers or resources! Kind Regards, Wulf
Re: T5 and JS UI Frameworks
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) -- View this message in context: http://tapestry.1045711.n5.nabble.com/T5-and-JS-UI-Frameworks-tp5716703p5716704.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: T5 and JS UI Frameworks
Sounds like vaadin. We use smartgwt in our apps within tapestry. It works great along with an integration layer in the FlowLogix library.

Re: calling java native functions in T5
I highly doubt it but T5 is always updating so you might have to read the docs thoroughly to make sure.

Ivan, Preeviette !!! Thanks for the generous contribution and good faith. I am excited. I will give that a shot over the weekend. Your tech support for tapestry 5 looks good. I will be as generous to post my widget when I get it QA'd... going to be some weeks though... each month I think i have time and keep getting clobbered with interference.

RE: t5: adding http header
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(OrderedConfigurationRequestFilter
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.

Re: t5: adding http header
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) -- View this message in context: http://tapestry.1045711.n5.nabble.com/t5-adding-http-header-tp3369097p5716463.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: T4 to T5 select component usage
1. To place components defined in java class on your template you should
use t:id attribute equal to field name(id attribute references clientId
logic). As you don't use this attribute in your code snippet you have 2
separate selects. One of this selects are defined within java class and
doesn't present on template, so you have an exception(As far as I
understand you have such mistakes with page and tableColumnsSelect components
too). To fix this issue you can:
1) set t:id attribute:
select t:type=Select t:id=itemsPerPageSelect
model=literal:5,10,15,25,50,
100,250,500,1000,5000,1
value=itemsPerPage
/
2) remove component definition from java class(if you don't use it for
custom validation)
2. To use select component dynamic behaviour you should wrap it with zone
component and define its zone parameter. Default event propogated will be
EventConstants.VALUE_CHANGED:
TML:
t:zone t:id=updateZone
...
select t:type=Select t:id=itemsPerPageSelect
model=literal:5,10,15,25,50,
100,250,500,1000,5000,1
value=itemsPerPage
zone=prop:updateZone
/
...
/t:zone
JAVA:
@Component
private Zone updateZone;
public String getUpdateZoneId() {
return updateZone.getClientId();
}
@OnEvent(value = EventConstants.VALUE_CHANGED, component =
itemsPerPageSelect )
public Object onItemsPerPageChange() {
...
return updateZone;
}
http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/corelib/components/Select.html
3. Select component doesn't have defaultValue parameter.

Guys/Gals (if any),
I am upgrading some T4 code to T5
I have a T4 select component configuration/usage as follows:
--- TML snippet ---
tr
td width=25% align=left nowrap=NOWRAP
t:LabelItems Per Page/t:Label
select t:type=Select id=itemsPerPageSelect
model=literal:5,10,15,25,50,100,250,500,1000,5000,1
value=itemsPerPage
defaultValue=9
onchange=tapestry.form.refresh(this.form)

--- JAVA snippet ---
@Component(parameters =
{ event=itemsPerPageChange, clientId=itemsPerPageSelect })
private Select itemsPerPageSelect;
@OnEvent(value = action, component = select)
public Object onItemsPerPageChange()
{
...
Am I missing something ? I don't understand the error below as to why this
configuration is not sufficient.

Re: T5 Auto Binding of DAOs
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

T5: how to catch the exceptions thrown by the event handler?
Hi there,
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());
}
But seems that the catch parts never get executed, T5 just redirects the
request to the exception page.
Thanks,
Yunhua

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.

Re: T5 Auto Binding of DAOs
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.

Have you taken a look at Tapestry's ClassNameLocator and
