question about recursion in a component.
Hallo everybody.
My question is about how could I implement a recursion in tapestry 5?
exactly in a tree component. I have a collection of nodes with a Node
father and a Collection children, then in the tml I have a loop and
check if the actual node is father or not, but I want execute again the
same control for each children.
t:loop t:source=source t:value=item
t:if t:test=father
tr
td width=1% valign=top style=cursor:pointer
img src=images/plus.gif border=0
onclick=javascript:UTILS_Change_Display('${item.identifier}')/
/td
td width=1% valign=top
img src=images/folder.gif border=0
alt=${item.identifier}/
/td
td width=1% nowrap=true valign=top
onClick=javascript:UTILS_Change_Color('name_${item.identifier}',
'black', '#ff');
span id=name_${item.identifier}
style=cursor:pointer
${item.name}
/span
/td
td width=* valign=top
div id=${item.identifier}
name=${item.identifier} style=display:none
table border=0 cellspacing=0
cellpadding=0
Here I want implements the recursion (at the momment I have another loop):
t:loop t:source=item.children
t:value=item
tr
td width=1%
/td
td width=1% valign=top
style=padding-right:1mm
img src=images/folder.gif
border=0/
/td
td valign=top
${item.name}
/td
/tr
/t:loop
/table
/div
#160;
/td
/tr
/t:if
/t:loop
I'm new in tapestry and I don't know if is possible or not.
Thank you very much in advanced.

[T5] crating component libraries
Is there a description somewhere on how to create component libraries in tapestry5? I had a look at the users guide an the into the wiki but did not find a suitable description. Thnaks, Andy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [T5] crating component libraries
create a project following the t5 package name conventions
eg.
my.package.structure
my.package.structure.pages
my.package.structure.components
my.package.structure.mixins
create a MyModule class that is referenced by
the MANIFEST.MF file and contains a LibraryMapping
contribution
public void contributeComponentClassResolver(ConfigurationLibraryMapping
configuration)
{
configuration.add(new LibraryMapping(somePrefix,
my.package.structure));
}
done :)

Re: server hangs with parallel requests

[T5] OnActivate methods order call with super classes
Hello,
With 5.13 and 5.14, I have a strange behavior when I add an onActivate
method in a super class. The methods are not called in the same order
in my child class.
public class ParentPage {
}
public class ChildPage extends ParentPage {
public void onActivate(Entity e) {
System.out.print(Hello );
}
public void onActivate() {
System.out.print(World );
}
}
Like this, I get Hello World.
Now, if I had a onActivate() method to my ParentPage, I get World
Hello. Tapestry doesn't call the methods in the same order.
Is it a bug or did I misunderstand documentation ?
Thanks,
Denis

RE: Class not found exception
Hi,
I asked about this a few weeks back and Ben Gidley pointed me at the
wiki with these words
What is happening is Jetty hides 'server' classes from the web
application unless they are also in WEB-INF/lib. When you run in the IDE
you don't have a WEB-INF/lib so it can't find the slf4j classes as they
are loaded by Jetty as server classes.
You are starting Tapestry inside your IDE using a Run class - you need
to add a line into your startup class saying
// Remove slf4j from list of classes not exposed to webapp
webapp.setServerClasses(new String[]
{-org.mortbay.jetty.plus.jaas., org.mortbay.jetty.});
see http://wiki.apache.org/tapestry/Tapestry5RunViaMain for more
details.
Hope that helps

Thanks Russell.
I had seen that one too but I'm afraid that, while I understand the
underlying problem, the wiki entry solution doesn't mean a great deal to
me as I am have not been using Maven for very long and don't know much
about POMs or artifacts.
I don't see why I should have to have a run class. Surely it should
just all work out of the box (or at worst, by modifying a Jetty XML file
as I initially tried).

Typo on my part. I meant Run Jetty Run:

which is an Eclipse plugin.

Thanks Russell.
I had seen that one too but I'm afraid that, while I understand the
underlying problem, the wiki entry solution doesn't mean a great deal to
me as I am have not been using Maven for very long and don't know much
about POMs or artifacts.
I don't see why I should have to have a run class. Surely it should
just all work out of the box (or at worst, by modifying a Jetty XML file
as I initially tried).

Hi,
I asked about this a few weeks back and Ben Gidley pointed me at the
wiki with these words
What is happening is Jetty hides 'server' classes from the web
application unless they are also in WEB-INF/lib. When you run in the IDE
you don't have a WEB-INF/lib so it can't find the slf4j classes as they
are loaded by Jetty as server classes.
You are starting Tapestry inside your IDE using a Run class - you need
to add a line into your startup class saying
// Remove slf4j from list of classes not exposed to webapp
webapp.setServerClasses(new String[]
{-org.mortbay.jetty.plus.jaas., org.mortbay.jetty.});
see http://wiki.apache.org/tapestry/Tapestry5RunViaMain for more
details.
Hope that helps

RE: Class not found exception
I don't think run jetty run supports configuration by a jetty.xml. The
author says in his Usage instructions
There aren't many options, just the web application directory, the
context and the port. I intentionally keep it basic so that it will be
easy to use and maintain; if you need anything more fancy, use one of
the other Eclipse app server plugins, or do what I often do: create a
start up class in your project.
Not sure where that leaves you. Sorry I can't be more help. The basic
problem is the same. You need to tell Jetty that you don't want it to
hide the slf4j server classes. One way of doing that is setting the
ServerClasses property as Ben did below. How you set that property with
run-jetty-run is beyond me. Sorry.
If you look at the wiki post linked to in my post you can just cut and
paste the code into a run class and you will be up and running very
quickly indeed. I agree with your shoulds...but maybe ditching
run-jetty-run would help.
Cheers
Russell

Re: T5: Stop Receiving Request
This is interesting, is there a way to know before the file is sent the
size
of coming upload?
From the client side you do not have access to the file that is going to be
uploaded, all you can do is inspect the POST on the server side. I believe
that most modern browsers will send the content-length along with the file
so that it can be rejected before much data has been read off the wire.
Tapestry is using http://commons.apache.org/fileupload, you can read up on
what's possible with this library.

I believe this will work, but I have not tested it.
public static void

If you want to have a different max upload size per form, then I'd guess
you'd want to replace/supplement the MultiServletRequestFilter.

Hi User-Group,
I expirence the following Problem:
Using Tapestry + GWT I send a UploadRequest to a Tapestry Page.
Once the Upload is processed the HTTP-Page containing 'OK' is
returned, otherwise the Name of the Exception/Reason.
On the server side the T5-page checks the size of the
request-payload and response with a OversizedException. This
exception is send to the client. This works very well with a
single problem:
Sending 300MB of Data the browser blocks until all 300MB are
Transmitted but the page/server immediatly (used sysout to ensure)
Rejects the transmittion by writing the OversizedException to
response (MarkupWriter).
I tried several things to stop the request upload from browser.
I tried to open the content-input-stream of the request and
Immediatly close this stream. With virtually no effect.
Is there anyway to stop/break/destroy an request-upload of that
size?
Since all three major browsers (Opera, FireFox, IE) behave in the
same way I guess the problem lies on Server-Side. So who is to blame
for? Tapestry? (Dont think so), Tomcat?, Browsers?
(In Short: You want to upload 300MB? I just read 10K and Say No To you!)
Cheers,
Martin (Kersten)
PS: This is the Ajax way of doing things. The form (upload) is send to
the server and the target of the response is an 'hidden' Iframe.
PSS: If it is the browser I just would use the Upload Progress Listener-
Mechanis I use to get the progress of the current upload.

T5: Only one decorateRequestExceptionHandler is used even though I have defined more than one
I have two submodules and in each submodule I have defined a decorateRequestExceptionHandler. The problem is that only one is used. For only the first submodule that defines the decorateRequestExceptionHandler method the decorate method is called. If I add decorateRequestExceptionHandler to the 'main' module only the decorateRequestExceptionHandler method of the main module is called. I thought it was possible to have multiple decorators for the same service. From the Tapestry docs It is also common to have multiple decorations on a single service. In this case, a whole stack of interceptor objects will be created, each delegating to the next. Tapestry IoC provides control over the order in which such decorations occur. So is this a bug?
