modify Palette values in js.
Hi all, I am using Tapestry 5.3. I have a page with a pallette and a custom component. I need to modify the palette available values when the custom component values changes by a user action. If i do this by javascript then when i submit the form, tapestry pallete complains because it has different values in its model. 1) Is there a known solution to this case in order to avoid calling the server everytime my custom component values change and updating the pallete model and its zone? Cheers and thanks in advance!
Re: tapestry+jboss live class reloading problem
Hi Thiago, Thanks for your answer. I understand perfectly what you say. Now i am looking for someone that has the same enviroment as me (tapestry+maven+jboss+jboss tools) with some tapestry lib included in the main project in order to know if there is some configuration i am missing. Is there anyone with that scenario?

tapestry+jboss live class reloading problem
Hi, all I am facing the following problem with Tapestry live class reloading and jboss application server. Up to last month i was using maven+jetty+tapestry with eclipse IDE to develop and debug my web applications. I have two tapestry projects , the first one is the Webapp with custom styles and some tml files, and have a dependency to the second one that is a WebLib where i have tapestry components and pages that are reusable and generic for that webapp and some others. Live class reloading was working fine in both projects because my maven jetty plugin configuration did not have to create a jar of the weblib and uses files in target directory. This month we have decided to migrate our projects to Wildfly server (Jboss) because of some transactional web service requirements. We are using Jboss Tools eclipse plugin to deploy projects to application server using configuration found in jboss forum: https://community.jboss.org/en/tools/blog/2011/02/21/getting-started-with-jboss-tools-jboss-maven-integration-and-weld All is working fine except from weblib project that is now deploying to the jboss server as a jar file. I know that live class reloading do not reload tapestry files that are inside jar files like tapestry documentation says, but perhaps someone have faced the same problem and can tell me if there is any special configuration to apply in order to use live class reloading like i was. Cheers and thanks in advance! Leandro.

tapestry + maven + jboss tools + hot deploying ?
Hi all, I got the following scenario, - A Tapestry 5.3 web application called project A (contains tml files, java pages files, and common web files) - A Business logic project called B (Business services) - A Model project called C (pojos with hibernate annotations and daos) - I manage project dependencies with Maven 2. - I deploy project from eclipse(Juno) using Jboss Tools(1.4.0) and Jboss Tools Maven Integration(1.4.0) to a Wildfly 8.0.1 server . In order to deploy web application i have created a new server (jboss server type). I run my A project into the mentioned server. All is working fine except i want tml files changes to be taken on the fly without the automatically re deploying of the application. Questions: 1) Is there a way to change tml and java files on project A without the need of redeploying the whole app?? The server configuration has an option to publish the project (re-deploy) when a resource has changed. But it redeploys the whole application also when i change tml files from project A. The worst part is that session data get lost and i have to re login to application and complete forms again. If i chose Never publish automatically none of my changes are seen by server. 2) If answer to question 1 is positive now i want to know if is there a way to change and compile project B and C classes and see the changes without redeployng web application? 3) I know Tapestry's Jumpstart application works on JBoss/Wildfly does anyone knows if T5's class reloading works in JBoss? At least it's not working for me, Geoff do you have any thoughts on this topic? cheers and thanks in advance! Leandro.
Re: how to refresh page zone inside a component
Thank you Lance.
I will try your solution as soon as possible.
Then i will write to you again telling about the results obtained.

Lets assume you are writing a LinkTree component which accepts a
LinkTreeModel parameter. LinkTreeModel has a visitAll method which takes a
LinkNodeVisitor.
You could do something like this (not tested)
LinkTree.tml
---
t:block id=linkBlock
t:eventlink event=linkEvent${linkLabel}/t:eventlink
/t:block
LinkTree.java
-
public class LinkTree {
@InjectComponent
private RenderCommand linkBlock;
@Property
private String linkEvent;
@Property
private String linkLabel;
@Parameter
private LinkTreeModel model;
public RenderCommand onBeginRender() {
return new RenderCommand() {
public void render(MarkupWriter writer, final
RenderQueue queue) {
model.visitAll(new LinkNodeVisitor() {
public void visit(final
LinkTreeNode node) {
queue.push(new
RenderCommand() {
public void
render(MarkupWriter writer, RenderQueue queue2) {
LinkTree.this.linkEvent = node.getEvent();
LinkTree.this.linkLabel = node.getLabel();
queue2.push(linkBlock);
}
});
}
});
}
};
}
}

how to refresh page zone inside a component
Hi!
I am facing some problems with an own component. This component renders
some eventLinks with the use of componentResources and markupWriter.
I have included this component in a page with a zone near it that must show
some info based on the eventLink of the component clicked.
I want only the zone to be updated in order that the component do not
render again.
Does anybody knows how to update a zone in a page when any eventlink of the
component is clicked?
The eventLink created with markupWriter does not fire an ajax request, so
it refresh the hole page instead of only de zone.
Comments:
I have used markupWriter because i had to make recursive methods in order
to obtains eventLinks in diferent labels (like a Tree)
I am using Tapestry 5.1 and i cannot update this project to the latest one.
Here is some code:
Part of Page.tml:
div class=test
h1test Page/h1
ems:EmsElementTree zoneToUpdate=elementBrowserZone/
t:zone t:id=elementBrowserZone id=elementBrowserZone
div class=elementBrowser
information here based on the eventlink clicked
/div
/t:zone
/div
Part of Component.java:
markupWriter.element(div, class,row);
markupWriter.element(a, class, showElementBrowserLink,
href, componentResources.createEventLink(testLink,myData));
markupWriter.write(baseElement.getRootName());
markupWriter.end();
markupWriter.end();
public Object onTestLink(String element){
System.out.println(*ES AJAX: +request.isXHR());
return this.zoneToupdate.getBody();
}
Thanks in advance.
Leandro.
Re: how to refresh page zone inside a component
The line System.out.println(*ES AJAX: +request.isXHR()); is always
printing false.
Because the event link rendered with markupWriter does not add the
Tapestry.init linkzone to javascript code.

Re: how to refresh page zone inside a component
Sorry, but i do not understand how the RenderCommand can help me creating eventLinks that generates ajax requests to update a zone. Can you give me an example or more info? Thank you again, Leandro 2012/9/11 Lance Java lance.j...@googlemail.com You don't need to use the markup writer to generate recursive content.

When I am in B I want to know that before being here I was in page A. My tapestry version is 5.1.0.5 and i can't migrate the project to a new one because of some dependencies. Thanks in advance!

Re: last page visited
Hi again, I think that I have to describe the whole scenario so you can understan why i have written the question of the first email. Here is my situation: * I have two pages p1 and p2, each page belongs to layout A. This layout contains two tabs, one is p1 and the other is p2. * If I go to p1 page from two special pages I want to see just this two pages p1 and p2, but if I came from any other page I want to see that two pages plus three others, so I need other layout that contains the five pages.

Swf asset in jar root directory

ProjectA has projectB.jar in its libs directory. ProjectB contains a .swf file that is injected in a page of the same project.

Is there any way to inject an asset that is in the classpath root directory without relative path?? I can't use relative path because it is too long and it gives me an error.

Re: help with bug TAP5-587
Thanks Jim!
Now it works fine!
I have used the question mark with the solution of the bug that i have
passed in the first email!
thank you so much again!
Bye!
2010/12/22 Jim O'Callaghan jc1000...@yahoo.co.uk
When you say at the end of your email that Tapestry rendered the loop even
if the condition is false, how are you checking the condition? Have you
tried using the question mark operator in your output loop / condition to
stop output if an item is null? Ex.:
t:formatnull value=${contract?.manager?.address?.city?.name} /
... where if any of the hierarchy is null is will stop trying to evaluate
methods / properties on subordinates, avoiding a NPE.
Is it possible that where you are referencing a condition in a loop that
the
actual reference is invisibly instantiating something?
Regards,
Jim.

be variable. For that reason i have used the loop component but i get the
exception that you can look at TAP5-587 .
The cause of the bug is that when a volatile Loop in a form gets updated
through Ajax and results in having less source items than on initial page
render, a java.util.NoSuchElementException because the Loop seems to think
there are more source items then there are.
The report bug gives a solution, rewrite the Loop's advanceVolatile()
method, but it doesn't work, that solves the NoSuchElementException but the
form fails. The form wants to render some input, and read a null property
of
an object from the collection.
I tried to use an if sentence in the .tml, but it doesn't work. Tapestry
rendered the loop even if the condition is false, and throws the same
exception.
Any ideas?

Thanks Jim!

passed in the first email!
thank you so much again!
Bye!

When you say at the end of your email that Tapestry rendered the loop even
if the condition is false, how are you checking the condition? Have you
tried using the question mark operator in your output loop / condition to
stop output if an item is null? Ex.:
t:formatnull value=${contract?.manager?.address?.city?.name} /
... where if any of the hierarchy is null is will stop trying to evaluate
methods / properties on subordinates, avoiding a NPE.
Is it possible that where you are referencing a condition in a loop that
the
actual reference is invisibly instantiating something?
Regards,
Jim.

-Hi,
Is there any solution for bug TAP5-587?
I have searched in the releases notes, but a solution did not appear .
