Re: [ANN] Tacos 4.1.0 release

Re: T3: Upload
I've tested the example code on the page. It works with the exception
of file.isTruncated(), which has been deprecated, I presume.
So the rest of the code, ie the code you post below, does work.
It must be a configuration issue. Are you running this example page
in isolation, or is it part of a larger project? Are you running
from inside Eclipse? If not, how is Tomcat started?

t5: mock-up templates with sample-content then replace in t5
Hi,
in T4 it is possible to mock-up pages in your favorite html-editor (say
dreamweaver) including sample-content (for tables for example).
How can I achieve the same in T5.
I mean, I can add a table (see below) with dynamic content, but is it
possible to add sample content (which is replaced by the actual dynamic
content on launch) to this same table definition so that the design aspect
is integrated as well?
Thanks in advance,
Geert-Jan
table
tr t:type=loop source=items value=item class=prop:rowClass
td${item.id}/td
td${item.name}/td
td${item.quantity}/td

Combined Component Model - Is it supported ?
Folks... per doc text that follows... 1. Components that inherit from BaseComponent will use an HTML template. 2. Components that inherit from AbstractComponent will render output in Java code, by implementing method renderComponent() . I would like to build a component that operates combined semantics... or at least option 2 supporting the manipulation/usage of templates within JAVA. Option 1 only supports handlers not necessarily rendering + JSON. WHY? Some component templates are lengthy and I would not like to implement all that rendering in the JAVA as it is too cluttered/cumbersome. Plus some components are best fit in just a template and others are better fit in JAVA... I have a component anatomy a bit complex that requires everything and I want to distribute the implementation efficiently across both models. Can tapestry-4.1.2 deliver? If I commit to model #1 then I end up missing what I need. Same if I commit to model #2. I need both. Your feedback is appreciated.

Re: Combined Component Model - Is it supported ?
don't know if it's what you are looking for but you can always
override renderComponent also in BaseComponent decorating the
component template with some additional html e.g.
/* (non-Javadoc)
* @see
org.apache.tapestry.BaseComponent#renderComponent(org.apache.tapestry.IMarkupWriter,
org.apache.tapestry.IRequestCycle)
*/
public void renderComponent(IMarkupWriter writer, IRequestCycle cycle)
{
if (showComponent) {
writer.begin(div);
renderIdAttribute(writer, cycle);
writer.appendAttribute(class, getMyCSSClass());
renderInformalParameters(writer, cycle);
super.renderComponent(writer, cycle);
} else {
writer.begin(span);
renderIdAttribute(writer, cycle);
}
writer.end();
}
in this example, if the component is inheriting from BaseComponent ,
super.renderComponent(writer, cycle) , wil render the template
part of the component within
some other directly java manipulated html.
But it's not 100% clear to me what you mean with manipulation/usage
of templates within JAVA as in tapestry templates are manipulated
within java, meaning that you can change a template output quite a lot
using existing or custom components and ognl parameters binding.

Alternatively, can someone point me to T5.0.5's template

I found that using the JBoss UnifiedClassLoader instead of

class loader for web applications fixes the auto-reloading issues.
To change this setting you need to edit the following file:
JBoss 4.0.x
server dir/deploy/jbossweb-tomcat55.sar/META-INF/jboss-service.xml
JBoss 4.2.x
server dir/deploy/jbossweb.deployer/META-INF/jboss-service.xml
Search for the attribute UseJBossWebLoader and set it to true.
Note: Changing this may affect how your web-app resolves classes.
I think the Tomcat classloader always loads classes for the webapp
libs first, even if the class exists in a parent classloader.
The JBoss classloader says it follows standard behaviour
and will use
classes from the parent classloader over classes from the webapp.

Reply-To: Tapestry users users@tapestry.apache.org

Hello,
About this topic, I tried some investigations on my side,
and I found
out that the reason why classes don't auto-reload is that the
WebappClassLoader of tomcat 5 (I currently use tomcat 5.0,
but I guess
it's the same on Tomcat 5.5) keeps in cache (in a Hashtable more
precisely) all classes it already loaded once. And this
cache is never
cleared, except when the WebappClassLoader is stopped.
So, when the
class file is modified on the disk, tapestry 5 clears its
own cache,
and then asks to the parent classloader (WebAppClassLoader)
to reload
the class, which then serves the previous version of the
class from
its cache. The result is that the class is never actually updated
until the next restart of tomcat.
So, as a temporary solution, I tried to develop a class extending
WebappClassLoader that does not cache classes for packages
containing
.pages. and .components.. The source of this class is :
public class Tapestry5DevClassLoader extends WebappClassLoader{
private static String[] noCacheElements={.pages.,/
pages/,.components.,/components/};
public Tapestry5DevClassLoader() {
super();
}
public Tapestry5DevClassLoader(ClassLoader arg0) {
super(arg0);
}
@Override
protected InputStream findLoadedResource(String arg0) {
InputStream is=super.findLoadedResource(arg0);
if (is!=null){
if (isNoCacheElement(arg0))
return null;
}

Re: No redeploy, no restart ... --- yeah right
This is the thing. You can even do this with Weblogic Server - the trick is just that you have to start it up from within eclipse, and eclipse's class loader hooks for that j2ee container provide the classes. As long as you have a proper J2EE container starter that uses eclipse's own classpath locations, you should be able to do this. Christian.

By using the latest Eclipse build and wtp we're able to run Tapestry 5 on Tomcat 6 without restarting or redeploying anything. It seems most of the functionality comes out of Eclipse in this case, but it works... We're just using the default maven structure for our project, let maven build our eclipse project files (eclipse:eclipse) with wtp- compatibility enabled (-Dwtpversion=1.5) and in the Tomcat settings (dbl-click on the server definition inside eclipse) Serve modules without publishing enabled. In most situations this allows us to simply edit our files (java/html/css/gif) save them and go back to the browser to test them. Debugging doesn't work as smooth as this though, hot-deploying while debugging seems to fail and adding a new pages or component requires a server-restart as well :(. Hope this helps, Martin Howard Lewis Ship wrote: First off, developing locally using Jetty is a fine idea, even if you can't deploy the same way. In most any servlet container, updating the WAR causes an undeploy/redeploy that is outside of Tapestry's scope to control. Second, there's a whole lot more that Tapestry *could* do if it replaced the servlet container entirely and acted as its own HTTP server (possibly built on Jetty). But this falls into the boilling the ocean category. Third, there is unfortunately a lot of vaguness in the servlet API spec. Remy (Tomcat) sees the class loader issue one way, Greg (Jetty) sees it the correct way. I can't emphasis enough: use Jetty for your tight, local write-test- fix cycle (with no deploys, and fairly rare restarts). But using Ant or Maven to package your application normally for deployment.

Up until now I have never had a real answer, so I'm trying my luck again. On the home page of T5 I read: http://tapestry.apache.org/tapestry5/ It's more than what you can do with Tapestry ... it's also how you do it! Tapestry is a vastly productive environment. Java developers love it because they can make Java code changes and see them immediately ... no redeploy, no restart! But somewhere I else I read this (on Tomcat): http://tapestry.apache.org/tapestry5/tomcat.html Deploying Tapestry applications into Tomcat is relatively easy, with one big caveat: you must not store your Tapestry component classes under WEB-INF/classes. At startup, Tapestry needs to locate all your page and component classes, so that it can match page names in request URLs to page classes. Due to the way Tomcat creates ClassLoaders, this information is not accessible to Tapestry. Fortunately, Maven has an option inside its war plugin, archiveClasses, that changes the packaging; instead of putting compiled classes and resource files in WEB-INF/classes, they are instead placed inside an additional JAR inside WEB-INF/lib. This keeps Tapestry happy at runtime. Doesn't this mean that Tomcat cannot use the great productivity booster of No redeploy, no restart? I was told (by Howard) that for OC4J (Oracle's J2EE container) I had to do something similar as for Tomcat - so my guess is that No redeploy, no restart is also not feasable on that platform. So, can I conclude from this that T5 has improved a great deal - but not everything will work on servlet containers that are actually used?

Don't know why you need specifically to extend that class, it's not compulsory to have ajax (er even dojo) features. You can easily manage XHR/AJax requests using an EventListener annotation and selecting which components to partially update with ResponseBuilde.updateComponent(idOfTheComponentToUpdate) Or have your component (IComponent, it does not matter whether you extend or not other classes) implement IJSonRender interface that will return the JSON data structure to your javascript caller.

Re: T5: Using external Hibernate-mapped entities: the contribute method goes where?
Your AppModule is created with the same name used in web.xml (as Robin pointed out). By default its AppModule.java, as created by the quickstart archetype. You should find that to use Hibernate you need only to add it, annotations, and tapestry-hibernate to your pom.xml. After that you need only to @Ineject Session instances into classes/components/pages where you want to use it. For the record, I did a test with entities in a different package (not *.entities) and was able to use Hibernate fine. This is because the tapestry-hibernate module auto-loads (and maganges) sessions based on hibernate.hbm.xml, which also is responsible for loading entities (unless you configure via another method).

Re: Combined Component Model - Is it supported ?
Is the @RenderBlock specified from within the template or within the JAVA? RenderBlock is a component, it's actually a component marking where a specified Block component (could be chosen dynamically at runtime) will be rendered. As any component can be defined in the component definition java file or with java annotations, neverthless it's position in html must be specified in the html template. What the Block/RenderBlock option gives you more with respect to other solution is the fact that you can can choose completely different Block to render at runtime (in fact any other component that can be contained in a Block component), see the tab example in the user guide: it's a non ajax example but could be easily turned in an ajax update just using an EventListener and a ResponseBuilder.updateComponent call. http://tapestry.apache.org/tapestry4.1/components/general/renderblock.html How would I rig up a listener=listener:edit within the JAVA? Why would you want to do that? Really I can't understand your case. What you mean with rig up rig up a listener=listener:edit within java? the writer you use inside a renderComponent just generate final output for the browser, it's not meant to be parsed again in search of components. If you want to add a link to your component I suggest you to use a DIrectLink component in your component and use customer components (with or without templates) for the rest. You can then incorporate your components and other components in a super component. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: T5: Newbie question - using a variable and replace it with a property
Whatever your app/context name is (by default its App as created by the
quickstart), create an App.properties file in WEB-INF. Assuming you've
done that and you have your applicationTitle message, access it in
templates using the message binding prefix:
title${message:applicationTitle}/title
When you use expansions (${}) Tapestry uses a binding prefix to know
what it is and where to find it. The default prefix used in templates is
prop, which instructs Tapestry to look for a property in the
associated page class.

RE: Combined Component Model - Is it supported ?
Thanks Martino... I am still confused... The action handlers for each auto-paging button (or link) needs to dispatch to a handler. Handlers are normally assigned in forms. Here is the layout of the auto-paging links 1 2 3 4 5 6 7 8 9 10 content goes here 1 2 3 4 5 6 7 8 9 10 Upon click of these I need to dispatch to handler and recalculate metrics. Then content lays out the collection. I am seeking the simplest solution to make this a widget... or composite widget. My motivation to use JSON was it's use in script capabilities in persisting each actions state to the metrics across the request.

Re: T4: Components in Page get Initialized even if its in IF condition block ?
That's correct; think of your component as a listener, listening, not for when /it/ is starting to be rendered, but when the /page/ is starting to render. So, the component's pageBeginRender is always called, since the component is asking to be notified of when the /page/ starts to render, regardless of whether the component is rendered. Basically, the order of events is along the lines of: fire page validation events fire page begin render events render component 1 in page ... render component n in page fire page end render event Robert On Oct 1, 2007, at 10/12:17 PM , sunilmanu wrote: Howard, thanks for ur reply..but still my doubt is..

[T5] Entities (nbsp;, etc) are not preserved by template parser
Hi all, I've noticed that entities are not preserved in the generated html output (nbsp; becomes the actual character for a non-breaking space). This has not shown up as a problem in any browsers that I have tried, but it has been a problem when emailing the content of the page (I'm sure there is a character encoding mismatch in the workflow somewhere). Would anyone else consider this to be a defect? Josh By the way, as of this weekend http://www.thedailytube.com has left it's Cold Fusion roots and been migrated to T5 on Tomcat. So far so good! -- -- TheDailyTube.com. Sign up and get the best new videos on the internet delivered fresh to your inbox.
Re: T4: Components in Page get Initialized even if its in IF condition block ?
Thanks for the reply and information.. So is there any other method that could be used to initialize the properties needed for the page other than pagebeginrender method .. ? Or I have to pass in a parameter and check it's value inside the pageBeginRender and see whether to process or not ? thanks, Sunil Robert Zeigler wrote: That's correct; think of your component as a listener, listening, not for when /it/ is starting to be rendered, but when the /page/ is starting to render. So, the component's pageBeginRender is always called, since the component is asking to be notified of when the /page/ starts to render, regardless of whether the component is rendered. Basically, the order of events is along the lines of: fire page validation events fire page begin render events render component 1 in page ... render component n in page fire page end render event Robert On Oct 1, 2007, at 10/12:17 PM , sunilmanu wrote: Howard, thanks for ur reply..but still my doubt is..

I think the Tomcat classloader always loads classes for the webapp

The JBoss classloader says it follows standard behaviour

Hello,
About this topic, I tried some investigations on my side,
and I found
out that the reason why classes don't auto-reload is that the
WebappClassLoader of tomcat 5 (I currently use tomcat 5.0,
but I guess
it's the same on Tomcat 5.5) keeps in cache (in a Hashtable more
precisely) all classes it already loaded once. And this
cache is never
cleared, except when the WebappClassLoader is stopped.
So, when the
class file is modified on the disk, tapestry 5 clears its
own cache,
and then asks to the parent classloader (WebAppClassLoader)
to reload
the class, which then serves the previous version of the
class from
its cache. The result is that the class is never actually updated
until the next restart of tomcat.
So, as a temporary solution, I tried to develop a class extending
WebappClassLoader that does not cache classes for packages
containing
.pages. and .components.. The source of this class is :
public class Tapestry5DevClassLoader extends WebappClassLoader{
private static String[] noCacheElements={.pages.,/
pages/,.components.,/components/};
public Tapestry5DevClassLoader() {
super();
}
public Tapestry5DevClassLoader(ClassLoader arg0) {
super(arg0);
}
@Override
protected InputStream findLoadedResource(String arg0) {
InputStream is=super.findLoadedResource(arg0);
if (is!=null){
if (isNoCacheElement(arg0))
Re: T3: Upload
I've removed that deprecated method from my page.
I'm running this example page as part of my original project. And running
from inside Eclipse. All other pages working ok. That's how I normally test
any example before using into my real page.
In the example code there is no .page file. Is my .page file ok?

I've tested the example code on the page. It works with the exception

So the rest of the code, ie the code you post below, does work.
It must be a configuration issue. Are you running this example page
in isolation, or is it part of a larger project? Are you running
from inside Eclipse? If not, how is Tomcat started?

I just assumed that the same session would be used. anyway, it was interesting to see how a persistance stategy was contributed. 2007/9/24, Ted Steen [EMAIL PROTECTED]: the contribution should be to the PersistentFieldManager of course 2007/9/24, Ted Steen [EMAIL PROTECTED]: Ok! After digging a little deeper I now see that extending the AbstractSessionPersistentFieldStrategy and letting the prefix contain the host name should be a solution! I then contribute this to the ApplicationStatePersistenceStrategySource. Any objections? :) 2007/9/24, Ted Steen [EMAIL PROTECTED]: A page in our application can be in different states (depending on the sub domain). When a field is persisted, the state of the page should be taken in to account. For example if the page is accessed via the host name a.my-host.com the page should have its fields persisted for the context A and if the page is accessed via the host name b.my-host.com the fields should be persisted for the context B. its important that if the user browses the page via a.my-host.com and then changes to b.my-host.com the persistent fields should not cross over! I am currently looking for a contribution to some sort of persist stategy service but I'm not really sure where to look, and also, I'm not really sure this is the right way. -- /ted -- /ted -- /ted - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [T5] Linkable rows with Grid component
Alternately, you could subclass GridRows to provide the hooks for what you
need, then subclass Grid to make use of your custom GridRows.
The components in Tapestry are not meant to be sacrosanct, just useful.
Though that does bring up the question of component compatibility between
releases. Hmph.

Having now had the chance to tidy up my example code, here's my MixIn code
for the Grid Component:
@MixinAfter
public class ActionRows {
public static final String event = rowAction;
@Parameter(value=click, defaultPrefix=literal)
private String action;
@Parameter(required=true)
private String rowid;
@Inject
private ComponentResources resources;
@AfterRender
void after(MarkupWriter writer) {
final String tbodyPath = div/table/tbody;
Element tbody = writer.getElement().find(tbodyPath);
if (tbody == null) {
throw new RuntimeException(...);
}
for (Node rowNode : tbody.getChildren()) {
if (rowNode instanceof Element) {
((Element) rowNode).attribute(on + action,
window.location.assign(' +
resources.createActionLink(event, false, new Object[] { rowid }) + '));
}
}
} // end of AfterRender method
} // end of MixIn class ActionRows
and here's a typical page-usage scenario:
@Component(parameters = { action=dblclick, rowid=row.id, row=row,
...
})
@MixinClasses(ActionRows.class)
private Grid displayData;
@OnEvent(value = ActionRows.event, component = ...)
public Object displayRow(int id) {
...
}
Hope that helps,
Carl.
