pageBeginRender and submit
Hi, I'm quiet new of tapestry. I have a problem in calling a page. My form in MyPage.html is form jwcid=[EMAIL PROTECTED] listener=ognl:listeners.submitMainForm delegate=ognl:beans.delegate input type=submit jwcid=[EMAIL PROTECTED] value=Salva selected=ognl:mainSubmitType tag=saveDay / /form In MyPage.java I have a method submitMainForm(IRequestCycle cycle) and the pageBeginRender method. When I press submit button, I see that is called: pageBeginRender method, submitMainForm pageBeginRender again. When is there a listener on form Is pageBeginRender method called before listener method? Which is the problem?

Re: pageBeginRender and submit
You can look here:
http://tapestry.apache.org/tapestry4.1/faq.html#submit-lifecycle
on form submit pageBeginRender is called before the form submit listener
discarding output in order to set page and page components in the proper
status before your listener is called.
As your next question might be what if I don't want to execute some code in
my pageBeginRenderr during first call?
The answer is check for cycle.isRewinding()
use
if(cycle.isRewinding()) { // This is the first rewind no output
pageBeginRenderer call code
/// Code
} else { // This is the second real output pageBeginRenderer call code
// Code
}
:-)

Create Shoutcast service in Tapestry.
We try to create a Tapestry-service that generates a Shoutcast stream. The
problem is that the shoutcast response must have a status line that reads:
ICY 200 OK
Instead, the status line we get is always:
HTTP/1.1 200 OK
Many mediaplayers (WinAmp, Xmms, iTunes) accept the header with HTTP status
line, but some do not. The ICY header is incorrect according to RFC 2616 and I
have been unable to generate a response with this status line.
Does somebody have a clue on how we could spit out a response with the ICY
like status line in it? Any help is appreciated.
The code we use now is basically like this:
private WebResponse _response;
[...]
private OutputStream initOutputStream(boolean metadata) throws
IOException {
OutputStream out = _response.getOutputStream(new
ContentType(audio/mpeg));
//Spit out Shoutcast-headers.
_response.setHeader(icy-notice1,BRThis stream requires a
href=\http://www.winamp.com/\;Winamp/aBR);
_response.setHeader(icy-notice1,MusiController
SHOUTcast-implementationBR);
_response.setHeader(icy-name,MusiController);
_response.setHeader(icy-genre,All sorts);
_response.setHeader(icy-url,http://musicontroller.sourceforge.net;);
_response.setHeader(icy-pub,1);
_response.setHeader(icy-br,192);
if (metadata) _response.setIntHeader(icy-metaint,BUFFER_SIZE);
log.debug(Outputstream initialized);
return out;
}
[...]
public void setResponse(WebResponse response) {
_response = response;
}

Hi all,
I cant get dojo EventListener to work.
The same happens with me :( Are there any preparatory steps to perform
to use EventListener? I have a template :
MyTemplate:
span jwcid=@Shell title=.:: Title ::.

@EventListener(elements = someId, events = onmouseover)
public void testEvent(PageEvent pe) {
log.info(Caught click!);
}
}
And it DOES NOT WORK :( Nothing appears on Tomcat's console...
Any advice would be greatly appreciated...

Re: Cant get Ajax @EventListener to work :( [+1]
Yeah you should see something along the lines of :
dojo.event.connect(dojo.byId(someId), ... .
towards the bottom of your page.
You might also try using Tapestry 4.1.2 instead of 4.1.1. They should
both work equally well but I can't remember if 4.1.1 had any issues in
this area or not.

Re: Create Shoutcast service in Tapestry.
Hi Hans,
The status line is output by the servlet engine - not Tapestry, since it
is a core part of the HTTP spec.
What you may be able to do, is create a javax.servlet.Filter which reads
the response from Tapestry into a stream, hopefully including the status
line - and then just re-output but with your new status line. Don't know
if that will work though.
Richard.

You can call IRequestCycle.getResponseBuilder().isDynamic() to see if it's a dynamic request and skip any heavy operations you don't need to perform.

Creating ajax-based expandable tree-like structures
Hi all,
I am trying to figure out some elegant way to use Tapestry to build
dynamic ajax-based tree-like UI widget. In general it's about showing
some hierarchical data:
* Some data item
* some sub property
* some sub property
* last level of props
* some sub property
Each level of that tree is (at least I planned in this way) a separate
component as on each of those levels different things are shown with
different actions. So here comes the question: how to approach this
problem in a way that could be implemented by someone, who knows basics
of Tapestry?
I thought about creating separate page (let's call it
AjaxComponentProvider) which would be called when user clicks an item.
This page would have injected components for those levels and would
render next level of components (by deleting rendering to
sub-components) as an XML. This XML would be then inserted into the
page. Thanks to such approach it would be easy to switch from AJAX-based
display to 'classical' one.
One thing that I can't find is how to obtain a String with URL to a
AjaxComponentProvider with some additional properties... My initial ACP
looks like this:
public abstract class AjaxComponentProvider extends DatapatrolBasePage {
public static final String pageName = AjaxComponentProvider;
public enum Action {GET_OCCURRENCE_DETAILS}
public abstract Action getAction();
public abstract void setAction(Action a);
@InjectComponent(OccurrenceInfo)
public abstract OccurrenceInfo getOccurrenceInfoComponent();
public DpOccurrence getShownOccurrence() {
CollectionDpItem items = MockDataProvider.createSearchedItems();
return (DpOccurrence)
items.iterator().next().getDpOccurrences().toArray()[0];
}
/**
* @see
org.apache.tapestry.BaseComponent#renderComponent(org.apache.tapestry.IMarkupWriter,
org.apache.tapestry.IRequestCycle)
*/
@Override
protected void renderComponent(IMarkupWriter arg0, IRequestCycle arg1) {
OccurrenceInfo oic = getOccurrenceInfoComponent();
oic.render(arg0,arg1);
//super.renderComponent(arg0, arg1);
}
}
And on a page that is supposed to use ACP to obtain some sub-level I
wanted to put something like
@InjectPage(AjaxComponentProvider.pageName)
public abstract AjaxComponentProvider getAjaxComponentProvider();
public String getLink() {
AjaxComponentProvider acp = getAjaxComponentProvider();
acp.setAction(Action.GET_OCCURRENCE_DETAILS);
String toRet = // here I need to get string with url to
AjaxComponentProvider page with props set
return toRet;
}
this getLink() method would be used in composing javascript on the
template to create ajax requests...
What are you thoughts about it? Am I missing some much easier and
elegant way to do this?

Re: It's working now - but HOW does it work? ;-)
I've run into this problem on some heavyweight pages using Tap 4.0 and Tacos 4.0. I basically had to modify all my pages so that models are initialized only on access. If I need a model to reinitialize after the rewind cycle, I set it back to null during a listener method. In Tap4.0 + tacos, even that wasn't really enough to get me any efficiency gains, since the whole page must still rewind, so all the models were firing, anyway. At best, I was sparing myself the re-initialization of any models that were updated for the render cycle. I solved this by introducing some infrastructure to my pages such that a model is able to check whether it is needed for render, rewind, both, or neither during ajax (dynamic) updates. I just initialize a dictionary in the .page file or via the InitialValue annotation which specifies which models have which update modes. The advantage of this is that I can serve up empty models during the render phase, even if I needed the correct model during rewind, so that Tap doesn't waste a bunch of cycles spewing lots of options to a null writer. It was a pretty simple refactoring of my code, but it required lots of typing, since I moved from using astract model getters and setters with an initializer in pageBeginRender calling the set method, to having fully specified getters and setters that check if the stored value is null before creating a new model, but only if is not an ajax update or the model is specified as being needed for the current cycle. Modifying existing pages was a pain in the neck, but working with new pages is very simple. It is yet another declarative thing that isn't checked at compile time, though, although I'm sure if I thought about it, I could concoct a way to fix that. Doesn't seem worth the effort, though, since most of my models are now initialized in a base page class, since any page which don't use a particular model don't suffer the initalization hit, anyway. --sam On 4/3/07, Jesse Kuhnert [EMAIL PROTECTED] wrote: You can call IRequestCycle.getResponseBuilder().isDynamic() to see if it's a dynamic request and skip any heavy operations you don't need to perform.

Trouble with the Tap 5 tutorial
While trying to follow along through the Tap 5 tutorial (I realize it isn't finished), I ran into a problem. The create archetype made an AppModule class that has a couple of imports that do not resolve. Specifically: import org.apache.tapestry.ioc.annotations.Contribute; import org.apache.tapestry.ioc.annotations.Id; Neither of these annotations appear in the annotations jar that Maven fetched, so I thought I'd check the 5.0.3 version from apache.org or the tapestry-ioc distribution. No dice. They don't exist there either. Any suggestions on the correct way to resolve this problem? Thanks, Andy Zimmerman

I'm thinking an application state object is a good place to start here with methods like startConversation() and endConversation() with hibernate sessions managed by this service. Any thoughts?

Re: T5 Hibernate long conversations (session-per-conversation)
My problem with session-per-conversation is that its totally incompatible with clustering, since the objects in the detached session are not propogated to other servers. That being said; yes some kind of mechanism (as service, an ASO) to hold onto the sessions between requests, to support detach and reattach, etc. The tiny bit of work I've done on tapestry-hibernate (for T5) doesn't support this concept, but it can grow to encompass it.

Re: Create Shoutcast service in Tapestry.
You can still do HttpServletResponse.setStatus(int code, String message);
It's deprecated so there may be a better way but who knows..It
wouldn't make sense if they didn't let you do it.

Hi Hans,
The status line is output by the servlet engine - not Tapestry,
since it is a core part of the HTTP spec.
What you may be able to do, is create a javax.servlet.Filter which
reads the response from Tapestry into a stream, hopefully including
the status line - and then just re-output but with your new status
line. Don't know if that will work though.
Richard.
I already had a hunch that it would be something like this. Thanks for the
response. I will try to construct a filter. Never did that before, so it will
be a challenge :-)

We try to create a Tapestry-service that generates a Shoutcast stream. The
problem is that the shoutcast response must have a status line that reads:
ICY 200 OK
Instead, the status line we get is always:
HTTP/1.1 200 OK
Many mediaplayers (WinAmp, Xmms, iTunes) accept the header with HTTP status
line, but some do not. The ICY header is incorrect according to RFC 2616
and I
have been unable to generate a response with this status line.
Does somebody have a clue on how we could spit out a response with the ICY
like status line in it? Any help is appreciated.
The code we use now is basically like this:
private WebResponse _response;
[...]
private OutputStream initOutputStream(boolean metadata) throws
IOException {
OutputStream out = _response.getOutputStream(new
ContentType(audio/mpeg));
//Spit out Shoutcast-headers.
_response.setHeader(icy-notice1,BRThis stream requires a
href=\http://www.winamp.com/\;Winamp/aBR);
_response.setHeader(icy-notice1,MusiController
SHOUTcast-implementationBR);
_response.setHeader(icy-name,MusiController);
_response.setHeader(icy-genre,All sorts);
_response.setHeader(icy-url,http://musicontroller.sourceforge.net;);
_response.setHeader(icy-pub,1);
_response.setHeader(icy-br,192);
if (metadata) _response.setIntHeader(icy-metaint,BUFFER_SIZE);
log.debug(Outputstream initialized);
return out;
}
[...]
public void setResponse(WebResponse response) {
_response = response;
}

Prerendering a field
Hi all, Is there a quick way to trigger prerendering of some field (for a standard component, like @TextField) before another field, similar to @FieldLabel's prerender attribute? I'm trying to find a workaround for T's trick where if I want field A rewound before field B, I have to change sequence of A and B on the page. Most times that's OK, but sometimes the looks suffer, while there's no clear workaround. Thanks, A - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Prerendering a field
None that I know of. It's extremely hacky as it is with just FieldLabel / TextField.

Page w/o specification [T4.1.1]
This probably has been answered in the past, sorry if I'm repeating. Creating a simple page without specification (just the .html file, without the .page) always throws PageNotFoundException: Page 'page name' not found in application namespace. However, documentation mentions (http://tapestry.apache.org/tapestry4.1/usersguide/template.html): In addition, any HTML template in the web application context is considered a page, even if there is no matching page specification. For simple pages that don't need to have any page-specific logic or properties, there's no need for a page specification. Such a page may still use the special Tapestry attributes (described in the following sections). Is this a bug, or am I misinterpreting what's meant by simple page?

Re: T5 Hibernate long conversations (session-per-conversation)
Well, we will probably head into clustering some day. What pattern, then, can we use to do optimistic locking without hibernate long conversations? I don't think session-per-request can do it. bill On 4/3/07, Howard Lewis Ship [EMAIL PROTECTED] wrote: My problem with session-per-conversation is that its totally incompatible with clustering, since the objects in the detached session are not propogated to other servers.
