RE: [ADV] Upcoming Tapestry Training: London, Paris
Looking forward to it. SkillsMatter is in a new building too. -Original Message- From: Howard Lewis Ship [mailto:hls...@gmail.com] Sent: 22 December 2009 18:03 To: Tapestry users Subject: [ADV] Upcoming Tapestry Training: London, Paris I'll be doing two trainings with SkillsMatter (http://skillsmatter.com) in London (Feb 10 2010) and in Paris (Feb 15 2010). This is my standard three day Tapestry course, as described on my web page (http://howardlewisship.com/training.html) delivered at a much better price than I can normally offer ... especially if you act fast enough to get the 2-for-1 training in London! http://skillsmatter.com/course-details/java-jee/tapestry-web-development I teach Tapestry as a hands-on workshop, oriented towards Tapestry (and Java web development) newbies. The class has a proven track record for getting people up-to speed in Tapestry 5 quickly. This represents one of my many long-term goals for Tapestry: to offer public enrollment training and grow the size of the T5 community. If you are in the London or Paris areas, this is a great chance to learn Tapestry from the source. -- Howard M.

RE: Discussion
I don't agree with the OP that the ServerSide discussion shows Tapestry "has lost the battle" - two posters state they don't want to see Tapestry mentioned. That's all there is. However, I can't agree with you Thiago. The old saying is "if you say it enough times then people will believe it is true". If you are just going to stand by and let "trolls" post bad things about Tapestry unchallenged then they have won the argument - regardless of how bad their argument may be and how incorrect their views may be. After all, someone pitching up and wanting a framework will read what they've written and believe it. Who is to say these anti-Tapestry people are wrong? Not you - because you won't counter their arguments! :-) Sure - don't feed the trolls. But all that is necessary is to say something positive; not engage them in an argument.

Re: JSON in Tapestry
I'm not sure if IJSONRender will work with pages, but i know it works with components. The trick is then to generate a url that will rerender that component... similar to a directlink url that defines the updateComponents parameter accordingly On Tue, Dec 22, 2009 at 10:35, EveningSun wrote: > > I'm using Tapestry 4.1.6 by the way. > -- > View this message in context: > http://old.nabble.com/JSON-in-Tapestry-tp26885074p26885256.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 > > -- Andreas Andreou - andy...@apache.org - http://blog.andyhot.gr Tapestry / Tacos developer Open Source / JEE Consulting - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Well, if you want to do a custom JS, u can do a Zone Update of the Form,
then observe Tapestry.ZONE_UPDATED_EVENT, for doing some some custom JS!
But, that happens only after form submission and not before that!

[newbie] Intercepting client-side form validation/submission
Hi there,
Is there any existing facilities to trigger some custom Javascript
code _after_ validating the form?
I'm now doing it with some Javascript tricks:
===
...
Event.observe(window, "load", function() {
var f = $("myform").onsubmit;
$("myform").onsubmit = function(e) {
return f(e) && customFunction();
};
});
...
function customFunction() {
//return true to submit
}
===
Notice that the custom function is only called _after_ validation
_and_ only if it was successful.
Since this is all boiler-plate I'm going to make it a component that
can be nested within , but before that I want to make sure
I'm not reinventing something that already exist. Or just tell me if
I'm going the wrong way and the _proper_ way to do it.
Your input is much appreciated.
Kenneth

Re: Help with using DWR with Tapestry
The tapestry creator will look something like...
public class TapestryCreator extends AbstractCreator {
private String beanName;
public String getBeanName() {
return beanName;
}
// set by config in dwr.xml (see my prev email)
public void setBeanName(String beanName) {
this.beanName = beanName;
}
public Object getInstance() {
// Use this instead of WebContextFactory (suggested in my prev email)
ServletContext servletContext =
org.directwebremoting.ServerContextFactory.get().getServletContext();
Object bean = getTapestryBean(servletContext, getbeanName);
}
protected Object getTapestryBean(ServletContext servletContext, String
beanName) {
// look up the bean from the tapestry registry
}
public Class getType() {
return getInstance().getClass();
}
}
You will then use a dwr config similar to my previous email to define the
TapestryCreator and map it to a named service in the tapestry registry. As I
said, please download the DWR source and take a look at the SpringCreator
for inspiration.

One more thing to note is that DWR supports ajax filters which are basically interceptors on DWR services.

Re: Help with using DWR with Tapestry
For a bit more info your dwr.xml might look like this: Perhaps some of the tapestry gurus can help out a bit more here. For normal DWR usage in tapestry, you disable the tapestry filter for /dwr/*. It seems that you might want a bit of the tapestry filter's functionality but not all. For example injecting the request / response / session and creating a hibernate session. If you come up with a working solution, please post it back to the DWR user's list and we'll include it in the project.

Re: Help with using DWR with Tapestry
You might like to take this discussion onto the dwr user's list. I think it might involve writing a TapestryCreator which is able to look up services from the tapestry registry.

Re: Help with using DWR with Tapestry
I've a doubt, how will the Tapestry's @SessionState work with DWR ah??

JSON in Tapestry
Hi, I'm new to tapestry, now I want to create a page which could handle ajax
request and return JSON response. But I can't get it work. Here is what I
did:
First I have a page which extends BasePage and implement IJSONRender:
public abstract class JsonPage extends BasePage implements IJSONRender {
public void renderComponent(IJSONWriter writer, IRequestCycle cycle) {
System.out.println("RenderJSON!!");
writer.array().put("some data");
}
}
Then I have Home.page:
Then I have Home.html:
dojo.require("tapestry.event");
dojo.event.connect(tapestry, "loadJson", function(type, data, http,
kwArgs){
alert("load json!");
alert("data:" + data);
for (var e in data) {
alert(e + ":" + data[e]);
}
});
tapestry.bind("http://127.0.0.1:8080/war/app";, {}, true);
The client side will show a message box said "load json!", but the json data
that client retrieved is always an empty object. Also, the server console
does not print "RenderJSON!!", which means that the renderComponent of my
TestPage was never called. I don't know what to do. Could somebody help me
out? Thank you very much!!
