It means besides these components, TapestryTools support also custom components with different prefix with t:. It allow you to provide autocompletion for custom components from different libraries, and we have a nice editor in which developer enters mapping: x: org.example.components y: org.acme.lib.components In this mapping, a library prefix is mapped to a component package. So, every component from org.example.components package would have x prefix.

Re: Live class reloading very slow
Hi, your suggestion did improve reload when only template is changed. Still 6 seconds reload happens when I change page class. Hope this is also abnormal and someone has some suggestions how to fix it as well. to clarify : adding exclude ** for resources will stop eclipse from doing anything there, and this was wrong until I restored defaults for m2eclipse. by doing this maven added it's own resource processing to the build. After that templates get copied as soon as edited, Unlike with eclipse builder page reload is very fast 200ms for a page that reloaded 6 seconds before the changes were made.

Live class reloading very slow
Hi, I may be wrong but since T5 5.2+ live class reloading is much slower. I remember it being faster before for a page with maybe 10-20 components reload lasts for 5-10 seconds. it becomes worse with each component added. This is far from productive and far from advertised by the framework. It feels like going back to stone age of JSP and restarting whole server for simple change. We have been using tapestry since the beginning of T5, and a bit T4, I could swear it was not this horribly slow before. Another thing is the new handling of variables and page pool. it is awful for debugging... is there a switch to use old page pool ? Davor Hrg

Re: Live class reloading very slow
I've updated run-jetty, and tried with and without page-pool still 5-6 seconds load time. I decided to try to go as simple as possible ... empty page with layout component takes 500 ms - add a form .. it jumps to 700 ms - add few submit buttons ... jumps to 800 ms - add a component with a zone inside it .. jumps to 950 ms - add two more of same component and few lines of text ... jumps to 1200 ms This is awful ... I hope this can be fixed by configuring something ... etc... if this is T5 reality ... it is extremely unproductive and painful. :( :( :( Davor Hrg On Tue, May 24, 2011 at 6:26 PM, Joel Halbert j...@su3analytics.com wrote: Hi Davor, I use a similar spec.

You can use ParallelExecutor service just fine, and to use injection do not instantiate a task yourself but make it a service with scope perthread.

Documentation improvement maybe ?

?
Question: How do I store my page classes in a different package?
Answer: you can't
The statement there is that pages must be in root-ackage.pages subpackage
and subpackages under it...
it is true for a single root-package, but by adding a library mapping you
can have multiple root-packages
if you stop using src/main/webapp as place for page templates and use
src/main/resources
same like you use for components then the following is done easy:
public static void
contributeComponentClassResolver(ConfigurationLibraryMapping
configuration){
configuration.add(new LibraryMapping(, my.app.tasks));
configuration.add(new LibraryMapping(, my.app.chat));
}
you are still bound to have pages under root-package.pages for each mapping
this only a partial explanation ... a more detailed one should be
used...
I used this to separate my app into few sub-modules, each having own pages,
and to be able to add/remove module from production server by just omitting,
certain module's jar.
in the end the faq item mentioned could rephrased:
short answer: you can't original explanation...
long answer: you can but there are limitations, click here for a detailed
description on using library mappings.

Query parameters
I'm posting this to user group since it is mostly usage question. The new query parameter binding is a welcome addition, especialy in combination with replacing the page pool with static instaces. All nice and well, but how do I pass query parameters through PageLink or AcionLink ? Best to explain it through the example I'm using it with: There is a page that lists documents, and there is a search form with few fields. One field is the year which tells the page to limit to docs from that year. So I changed the @Persist to @ActivationRequestParameter and after submitting the search form I get a nice ur: docs/list?year=2009. Ok, this works well, I can have multiple tabs with different filters, much like php which I like very much and use often. but there are more things that do not work: 1. using PageLink from another page to jump to @ActivationRequestParameter 2. using ActionLink to pass query parameters (annotated with @RequestParameter) 3. If there are more than one such param there is no way to create a link to it self with one of them changed for example on page: docs/list?year=2009type=FI I can not create a link directly to docs/list?year=2010type=FI it would be nice to be able to write this: t:SelfLink q:year=20102010/... to get the mentioned result for that matter a namespace xmln:p=tapestry:parameter or new one like xmlns:q=tapestry:query would be nice for the ActionLink and PageLink.

I had this issue when my tapestry dependencies got mixed.
The project uses T 5.1.04 and an utility module declared T 5.0.7.
in runtime this created the issue, I guess because names changed for the

Today we realized that we weren't actually using anything from Equanda

took it out of our pom.xml file. (We then had to add the chenillekit

libraries)
After we made this change, we haven't seen the issue come up again.

Re: Switch from Prototype to jQuery?
Tapestry core can benefit from using less library code as possible.Use few
utility functions from the days crossbrowser libraries just started,
and those that are not too much to implement.
high level stuff from jquery protoype dojo yui etc. are all different in the
approach.
a list should be made what utilities are of essence for tapestry js.
some tapestry functions that use library a lot but solve a specific problem
could be left for plugin lib to reimplement.
a good point to start would be removing this prototype centric stuff I
mentioned,
element.getFieldEventManager()
with something like:
Tapestry.getFieldEventManager(element)
although changing the prototype of the Function class and adding the bind
to it no big deal you might consider changing the code like this:
this.repositionBubble.bind(this)
to
Tapestry.bind(this.repositionBubble,this);
it is longer, and bit uglier but more neutral I guess.
One may think this is pretty:
this.form.getElements().each(function(element)
{
var fem = $T(element).fieldEventManager;
if (fem != undefined)
{
// Ask the FEM to validate input for the field, which fires
// a number of events.
var error = fem.validateInput();
if (error ! firstErrorField)
{
firstErrorField = element;
}
}
});
but why not just replace the first line with:
var elems = Tapestry.form.getElements(this.form);
for(element in elems)
The impl of the func would be obviously
Tapestry.form.getElements = function(form){return form.getElements();}

the code can easily be rewriten to use
Tapestry.getFieldEventManager(element).showValidationMessage(message);
this removes need for prototype and extending dome nodes for this example
You can argue that other projects might rely on tapestry doing things
like
this,
but an compatible version for prototype can be left like this and version
for other libs
with the new approach (the other libs don't like prototype.js anyway).
This
can mean
that people with other js libs are fixed to tapestry core only but this I
suppose is ok for many

Do all pages/components work the same way if you move the scripts to the
top?
If that is the case, then it would be nice if a component could indicate
that the scripts should be at the top for the entire page.
If not, then there is a problem if you want to combine a component which
requires scripts at the top with a component which requires scripts at
the bottom.

Re: Switch from Prototype to jQuery?
One small example from tapestry.js
when looking at this as prototype centric app
it is totaly ok, but from the angle of enabling other libs this approach
is completely unnecessary and easily fixed.
again this is one example (rewriting all may not be as easy)..
this code is called (tapestry.js:551)
Element.addMethods(['INPUT', 'SELECT', 'TEXTAREA'],
...
getFieldEventManager : function(field)
...
searching whole source for tapestry core reveals that this function is only
used in tapestry.js
tapestry.js:588
element.getFieldEventManager().showValidationMessage(message);
the code can easily be rewriten to use
Tapestry.getFieldEventManager(element).showValidationMessage(message);
this removes need for prototype and extending dome nodes for this example

a while ago with T5.0.11. Now I restarted studying Tapestry, tried the

the table, but cannot insert into it. I found no exceptions. I tried with
the 5.0.11 version, it still works. I replaced the Tapestry version with
T5.0.15 and it breaks. Can it be that I have to upgrade Hibernate as
well?

Re: LazyInitializationException
remove @Persist from:
@Persist
private Gene gene;
and your onActivate method seems strange
perhaps if you return null instead of GeneDetails.class;
the session is closed after renderring, not before
the renderring is part of the request, but you chose
to persist the Gene and redirect to your self
in that case a new request happens and your problems..

I was able to resolve most of my issue using Google, Tapestry reference and Wiki, or the archives of this mailinglist, but this time I ran into a few things that I can't figure out. Here's the first one: I'm using the Grid component to display a list of some entities. The Grid itself has a few parameters to adjust paging behavior (namely pagerPosition and rowsPerPage) but there's no parameter to configure GridPager's range parameter. Now, I searched wherever I could, but didn't find a single example on how to adjust the default values of range which is 5. I have tried to do this declaratively, programmatically in the page's backing class, but just couldn't find the way to do this. So my question is: is there an easy way to do this? And if not - is there a hard way to do this? :) I think I mainly need some pointers to get me started. Thanks in advance!

I'm still a little new to Tapestry5, and before starting a large project we've decided to develop a small internal application using Tapestry5. I was working on this for some 3 weeks now, and so far I'm impressed! I was able to resolve most of my issue using Google, Tapestry reference and Wiki, or the archives of this mailinglist, but this time I ran into a few things that I can't figure out. Here's the first one: I'm using the Grid component to display a list of some entities. The Grid itself has a few parameters to adjust paging behavior (namely pagerPosition and rowsPerPage) but there's no parameter to configure GridPager's range parameter. Now, I searched wherever I could, but didn't find a single example on how to adjust the default values of range which is 5. I have tried to do this declaratively, programmatically in the page's backing class, but just couldn't find the way to do this. So my question is: is there an easy way to do this? And if not - is there a hard way to do this? :) I think I mainly need some pointers to get me started. Thanks in advance!

Re: T5: Dynamic asset path
it depends on what you need,
but you could combine the asset service to generate base path
and add the rest programatically
img
src=${asset:context:company}/$(company.id)/img/banner.gif/
this way you don't need a method
a component would be even better to avoid copy/paste

HINT tapestry - tapestry5 package rename
Hi, I've just refactored few of my t5 apps to rename package org.apache.tapesrty to org.apache.tapesrty5 It was very tiresome to do it for all classes one by one, so I tried a trick and it worked. This works for me in eclipse, it might be also used in other tools. 1. remove tapestry dependancy from the project (from pom or otherwise) 2. create the package org.apache.tapestry inside your source 3. use refactor rename on that package 4. delete the package from the source after that there are few thigs to do also: TapestryConstants was split into few classes org.apache.tapestry5. BindingConstants (PROP, LITERAL) MetaDataConstants (RESPONSE_CONTENT_TYPE...) PersistenceConstants SymbolConstants (PRODUCTION_MODE) org.apache.tapestry5.internal InternalConstants (TAPESTRY_APP_PACKAGE_PARAM...) PageRenderSupport was renamed to RenderSupport hope someone finds this useful :) Davor Hrg

The problem is identify the which image button has done the form
submission.
Coz i am doing two tasks from these two image buttons. one is for data
saving and one is for image uploading. Is there a way to find which
button
has done the form submission?
i tried like this
component Id's are upload and next respectively
public void onSelectFromUpload(){
System.out.println(onSelectFromUpload );
nextPage = null;
}
public void onSelectFromNext(){
System.out.println(onSelectFromNext );
nextPage = RegistrationStepTwo;
}
any idea ? thanks in millions..

Re: Grid Source Persist and Paging
If you do want to stick with this approach, persist the results in session, do search when form is submitted. now, to clear results you can do it in two ways: if you do not link to that page from many sides, add an activation parameter on each external link that parameter can be anytthing so you know user just came from another page. or reverse situation, add a parameter to all your local links and reset results when it is missing. this is a general explanation, .. no time to paste some specific code Davor Hrg On Mon, May 19, 2008 at 11:53 PM, Todd Orr [EMAIL PROTECTED] wrote: I have a Form and a Grid on my search page.

However, I'd like to not have the user's previous results (from session) populate the grid when the page is hit later on in a user's session after an initial search has been made.

Re: Threading issues with DB operations on OS X
what version of tapestry is it ? there has been a recent fix that changes the way trasactions are handled. before that database connections were on autocommit and sometimes that caused the problems you describe. if you commit explicitely the problem will most likely be gone ... Davor Hrg On Tue, Apr 22, 2008 at 5:26 PM, Moritz Gmelin [EMAIL PROTECTED] wrote: Hi, There seems to be some threading issues when doing database updates from page to page. E.G. we have a page that displays a list of elements in a Database table and a button that you can click to add a new entry. The button is a ActionLink. Its method handler adds an element to the database table and returns the user to the same page. Normally, for each click of the button, I can see one row added to the database and visible in the grid on the page. But sometimes if I click the button, the content of the grid does not change although I can see that an element was added to the database. From other similar problems we have with the application, I would guess, that the display of the new page happens with a new database session, where the old session's transaction (to add the element) is not yet finished. The environment we use is OS X with Java 1.5.0 and a PostgreSQL Database. Has anybody else seen this behaviour? Is there somewhere I can for a transaction to be completely finished before the new page is activated ?

Re: T5: component id, element id
if the component does not have an id
you can olso do follwing:
in the mixin... add an arbitrary hidden element before the component
set id for that element and use:
var anchor = document.getElementById(idOfElement);
var compDomNode = anchor.nextSibling;
you can do that also by putting an element after the component,
and thus use this approach only when id is not available
I dislike using explicit ids in my js app at all, but that's just the way
I like it...

The goal
-
To create a mixin that will attach a client-side javascript object to
the mixing component. This mixin should not know anything about the
component and remain completely genereic, needing only a DOM id to
provide to the JS object.
Requirements
-
To attach JS behavior, you need a DOM id. Therefore the mixin must be
able to obtain this value from the component.
Problems
-
Not all components generate DOM ids, in which case you have to provide
one informally.
For a mixin to be able to attach a JS object to an element generated by
a component, it has to be able to obtain that id.
Digging through api I have found 2 possible ways to obtain the DOM id.
1) If the component implements ClientElement, then
ClientElement#getClientId is the correct way.
2) If the component has used the MarkupWriter
(
http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry/MarkupWriter.html
)
to create the exact element from which we need the DOM id, then we can
use MarkupWriter#getElement to get that element before it is closed.
With that Element
(
http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry/dom/Element.html
)
we can see if a DOM id has been set by using Element#getAttribute (and
passing id as the argument).
Last notes
-
Perhaps I'm a bit delusional on this issue. At first I thought that the
DOM id was so important that there should be a more intimate handling of
it, perhaps moving the getClientId from ClientElement to
ComponentResourcesCommon, so that _every_ component has one. The problem
is that a component can be arbitrarily complex, generating markup of an
unknown hierachical depth of elements. In addition, the component body
may be constructed primarily by it's template.
I'm still thinking on this, but it seems like attaching a mixin to a
component's dom id will require explicitly telling it what that is.
Input still welcome :-)

Ah, id with no t: is just a parameter like any other. Try this mixin:

private String _id;
void beginRender(MarkupWriter writer)

The downside is if the component you are mixing into already has the
id parameter define, your mixin gets null. I'm not sure why they can't
share... the docs say
If the component and a mix both define a parameter with the same
name, then the component wins: the component's parameter will be
bound, and the mixin's parameter will be unbound.
but I'm not clear why that is the case.
Does that help?

Hi Josh,
Indeed t:id does work, but apart from the fact that I'm not entirely
sure what T5 does with that value as opposed to the un-namespaced
version (id), it doesn't fully work. The reason is because the Any
component, like many in the core lib, do not explicitly write a DOM id
in the HTML of the resulting element. So while this allows me to get
some id in java code (which I need), it doesn't address the problem of
their not being a DOM id, so of course my JS fails. The only ways
around
this that I know are:
1) Explicitly provide the id as the normal 'id' attribute in the
template as an informal parameter and provide another one in the t:
namespace, to be passed to the component. The problem with this is I
have to provide it twice, which aside from being annoying is
error-prone.
2) Have the mixin explicitly write a HTML id attribute to the tag of
the
containing component. This would be horrible in my opinion, because
without intimate knowledge of the component using the mixin, or any
other mixins coordinating behavior, you can't know be sure you won't
damage something (overwriting an id attribute already created, writing
a
second id attribute (which would be wrong), etc). And of course if the
mixin requires intimate knowledge then it's not a good mixin.
Thanks - any other ideas? :-)

MyMap is declared as MyMap extends TreeMap {...}.
The first parameter, a list of strings arrives safely to my component.
However, the other one, seems to be mixed up: when I try to access an
element in my ListMyMap, it turns out that Tapestry (nothing else
involved) have filled this list with String items, not the expected
MyMap items. In the end, there is a class cast exception when trying to
access the MyMap items as Maps.
In the Eclipse debugger, it seems that the value of the ListMyMap
instance variable is a single string holding what looks like the
serialized value of my ListMyMap list. The start is
[{key=value,key=value...
I've tried to contribute coercions between MyMap-Map, but this desn't
seem to help (?).
Basically, I'm stucked unless I write everything in several big pages
with duplicated code. Don't really want to do that. :-(
Any hints out there?

Re: T5, newbie: Component parameter passing problems
how is getRows declared in your page class ?

OK, thanks...
In my page, I have t:myComponent columns=prop:columns

The columns argument, a ListString is just fine.
The rows argument, a ListMyMap is the problem.
The page has a ListMyMap getRows() which is verified.
Looking in MyComponent.java, I have
@Parameter

@Parameter
private ListString columns;
public String getSomethingStrange()

The latter getter fails. The debug info is from a breakpoint inside this

Re: How is T5 tutorial?
Rob smeets (and maybe few more aliases) is definitely a TROLL, those interested in details read the rest of the mail... Yes, there we go again, again you waste our time, spreading fud, and the article you mention is far from unbiased, and most likely even posted by you (using another alias). Source code is great for learning about any framework, I keep source of every library I use so I can look what is going on when some code breaks unexpectedly. So if someone suggests you to look at the source code it is no reason to bash that person. You are definitely a TROLL because yor only advice was to switch to another framework, if you were a real user you would give a better advice instead. Everyone here will answer the best they can, I use some subset of features, and help people that have trouble with that stuff. As you always recommend Wicket one would think that you are a wicket user marketing a competing framework, But you don't even use wicket because there is no record of you ever asking a question on their mailing lists. So if you are not a wicket user, and you haven't had any contact with wicket mailing list how can you compare wicket and tapestry ? If you are a wicket user, identify your self and send few links to wicket mailing list threads involving you. I bet wicket devs would have few words to say to you about your fud which does no good to wicket or tapestry.

Re: [T5] Inner Enums of Pages and Components
This is most likely due to serialization of the enum in the session,
I use a workarround that does not affect the code too much,
and I can track references to the enum.
I persist a string variable, but always use enum.name()
to change the variable.
I use this to keep track of major blocks that are visible in a page or comp
private enum Blocks{EDIT,DETAILS, EDIT_DANGER}
I persist the string
@Persistprivate String _currentBlock = Blocks.EDIT.name
();
I return block:
public Block getCurrentBlock(){
return _resources.getBlock(_currentBlock);
}
whne I change current block, I use the enum
public void resetView() {
_currentBlock = Blocks.DETAILS.name();
_splitGoodId = null;
_containerId = null;
}
public boolean onGoTo() {
resetView();
return true;
}
public boolean onGoToEditor() {
_currentBlock = Blocks.EDIT.name();
return true;
}
this might be helpfull... and it is not too far from classic usage

Re: [T5] Inner Enums of Pages and Components
An idea: I belive it has many pitfalls :(, but might be useful an idea, tapestry could for example extend such enum (persist worker might trigger it) and add serialization code to it. Then when reloading it could force serializing enum values, plus if the value gets serialized outside tapestry it could be better handled (if servlet container serializes it). this might only help enums.. On Tue, Mar 25, 2008 at 10:57 PM, Howard Lewis Ship [EMAIL PROTECTED] wrote: I'm kind of surprised about that; are you storing the enum values outside of the page instance (i.e. in the session?) Inner classes are loaded by the disposable component class loader (the class loader that handles retry logic and class transformation). When a class changes, the class loader, plus and objects instantiated from that class loader, are discarded. If you place such an object in the session, it will hang around (keeping the class loader from being garbage collected) ... AND when the stored value is assigned to a field of the newly loaded page instance, it will fail with a ClassCastException because there's a new class (with the same name) loaded by a new class loader. I'd love to patch up these leaky abstractions a bit better, but that's partt of the price of running in your choice of servlet container; short of Tapestry being an application server, and not an application framework, it doesn't have sufficient control of things to make it any more seamless.

Re: T5: generic, onActivate and onPassivate
javassist has low level apis that allow accessing
elements reflective data, and after that it's same old reflection code,
for example when I treid t make GenericComponents for tapestry
I wanted to make a worker and put generic information into ComponentResources
@Component private EntityEditComponentVessel, Long _vesselEdit;
I found the way to get the declaration for the field from javassist:
I messed a bit with
//ClassTransformation is enhanced to return :
CtField.getFieldInfo2...
FieldInfo info = transformation.getFieldInfo2(fieldName);
SignatureAttribute.ClassType type = (ClassType)
SignatureAttribute.toFieldSignature(sig.getSignature());
System.out.println(fieldName+:TYPE:+type);//QDEBUG remove
TypeArgument[] typeArguments = type.getTypeArguments();
for (int i = 0; i typeArguments.length; i++) {
System.out.println(TYPE par:
+typeArguments[i]);//QDEBUG remove
}
the output is :
_vesselEdit:TYPE:tapestryutil.base.EntityEditComponenthr.crup.eri.web.entities.Vessel,
java.lang.Long
TYPE par: hr.crup.eri.web.entities.Vessel
TYPE par: java.lang.Long
after that I just could not get the parameter into ComponentResources
this was all nice but after some digging I found this nice class on jboss
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossretro/trunk/src/main/java/org/jboss/lang/GenericsHelper.java/?revision=227view=markuppathrev=227

But on second thought, you're right, maybe I should have cached a DOM tree.. since it would have a much better guarantees for replaying.

Re: AW: @Cached and caching in general
Tobias is right to ask about his,
I'm usin php for a long time now and output_buffer functions ob_*
are great for simplifying complex pages, adding caching without interferring
with internal code
people have asked about getting html output of page and etc.
if framework would allow access to markup on afterRenderTemplate
and if markup could be forced to serialize all HTML of the current element
it would allow creating a simple component that can wrap a part of
(processor heavy) code and catch the rendered markup. Then it would
allow it self to be rendered normaly only in some intervals and produce
cached raw output otherwise.
this would be very similar to output_buffer tricks in php.

The Buffer.java is the component ( so somewhere under components package ), and the BufferServices needs to go somewhere where Tapestry will not enhance it, so I put it under the services package. ). :) Sorry, but the cacheKey/Extra stuff is a little confusing, but maybe we can start a different thread/docs for that, or simplify to make it easier for generalization.. The Parameters are: 1) timeout: String a duration in which a cache value will be valid; format: hh:mm:ss if you want a one hour timeout: 01:00:00. if you want a 30 min timeout: 00:30:00 2) lastUpdated: Date it output this parameter (if bound), to let you know when the contents of the Buffer were last updated. So you can print out a small message Last Updated ## 3) cacheKey: String 4) cacehKeyExtra: String here is where it might get a little confusing.. it generates a key into the cache using the request server/port/context/path and cacheKey and cacheKeyExtra. So it focuses the cache onto the current server and webapp ( since we used a shared memcache this avoids developers and production webapps stepping on each others toes ). It then adds cacheKey (which defaults to the component's extendedId), and cacheKeyExtra (which defaults to empty). So by default just wrapping your stuff with buffer timeout will just work since the key will be something like server:port/context_PageName:buffer_#. You would set cacheKey if you wanted to generalize the contents of the buffer ( have the same Buffer component shared across pages ). You would set cacheKeyExtra if you wanted to specialize the contents of the buffer ( have the same Buffer component apply to subsets of request.. like if it's user specific ).

Re: T5 : How to access to a Component Body ?
actualy,
you need not even do anything on the server side for such tabs,
this can be easily achieved with a small javascript function.
go through all children and generate tab controls taking title attribute
as ctrl text:
child.getAttribute(title);
for example I have a small hacked up js just for it
it uses label instead title
var TapestryUtil = {
createTabs: function(id){
var elem = $(id);
var selected = elem.getAttribute(selected);
var tabs = document.createElement(DIV);
tabs.className = minitab;
var cont = document.createElement(DIV);
cont.className = minitab_content;
var ch;
while(ch = elem.firstChild){
elem.removeChild(ch);
cont.appendChild(ch);
var code = ch.getAttribute(code);
var label = ch.getAttribute(label);
var tab = document.createElement(A);
tab.href=#+(code||);
tab.className = minitab;
tab.innerHTML = label || code || unlabelled;
tab._refContent = ch;
tab.onclick = tabClick;
if(code != null selected != null selected == code){
ch.style.display == ;
}else if(selected != null)
ch.style.display == none;
if(ch.style.display != none) tab.className += selected_minitab;
tabs.appendChild(tab);
}
elem.appendChild(tabs);
elem.appendChild(cont);
function tabClick(){
var current = this;
this.blur();
var ch = current.parentNode.firstChild;
while(ch){
if(ch != current){
Element.removeClassName(ch,selected_minitab);
ch._refContent.style.display = none;
}else{
Element.addClassName(ch,selected_minitab);
ch._refContent.style.display = ;
}
ch = ch.nextSibling;
}
return false;
}
}
};

Hi,
He's having the same problem I had some time ago.
Suppose I want to create a Tab Component and I want to be able to

h1Body of tab1/h1
pContinuing body.../p
/t:tab
t:tab t:id=tabTwo title=Second tab
h1Body of tab2/h1

/t:tab
/t:tabs
If would then like to 'render' this about that way:
div class=tabs
ul class=tabTitles
lia href=. onclick=switchtabs(1);First tab/li
lia href=. onclick=switchtabs(2);Second tab/li
/ul
div id=tabOne class=tab selected
h1Body of tab1/h1
pContinuing body.../p
/div
div id=tabTwo class=tab
h1Body of tab2/h1
pContinuing body.../p
/div
/div
This is, I think, the most natural way of expressing tabs.
But such a thing is not possible, because the Tabs component cannot
accessing its child Tag components dynamically.
More: if you provide a body for a component (like above), you cannot
provide a template for this same component.
I haven't found a way to implement such a component, and I think I had
about the same initial problem as Christopher : A component cannot
easily access its 'children' defined in the base template, build an
internal model from that, and render using this model and an internal
template.

Thank you for your answer,
But actually my component must access its child in a dynamic way.
It will be used in different context for analysis purpose.
I've been searching for different ways to access a component body.
For exemple, by using nestedId at creation time by decorating the
PageElementFactory to identify if a component is contained in my
component, but the nestedId does not contain the id of the parent
component but is only suffixed to the container nested id.
By decorating ComponentPageElement and intercepting addToBody
method call for my component only, but it was not enough for the
children and I don't want to generalize the use of these kind of
hooks or wrapping mechanism because of the internal aspect of the
PageElementFactory and ComponentPageElement classes.

sounds reasonable, you feel strong about this, so add a jira to make it a serious req. Davor Hrg On Tue, Mar 11, 2008 at 2:58 PM, Alec Leamas [EMAIL PROTECTED] wrote: True. And a little better. But it still like pushing a square into a round hole: Tapestry does not support the natural way to do it. I presume we agree that from a user point of view, start presenting the entries we are looking for is the expected thing. Also, there is actually more in this. I can think of other, reasonable paging strategies e. g., some entries of overlap for each page. My gut feeling is that Grid should be more generic, and that a GridPager should be free to define whatever strategy it wants. I think the only thing which needs to be changed is the Grid's idea of the actual page being a row nr instead of a page nr. It shouldn't be hard to make this change without affecting current code. If required, one could even let setPage remain with current semantics?!

Ouch... That change botches up my current application pretty

I don't think the event needs to be re-named... but consider the
following situation:
If a form is in a layout component that other pages use via the
@Component annotation (say because most of the forms look very similar
and they want to re-use the presentation and validation logic), they
have no way of validating their forms in the pages, because they no
longer have access to the validate event from the form.
You can do onValidateFromLayout() ... that is, if Form is inside Layout,
then the event will bubble up from Layout to your page, and will appear
to originate with Layout.
Alternately, the Layout component could capture the Form's validate
event and trigger a new event with a name of your choice:
boolean onValidateFromForm()
{
_componentResources.trigger(layoutvalidate, null, null); }
I tried using the onValidateFromIndividualField() technique... the
behavior of that seemed inconsistent (had to submit the form twice to
get the event to fire???).
Huh?
Are you sure your client-side validation wasn't preventing the form
submission?
How does one log these events to see which events are firing?
That isn't really logged right now.
Looks like I'll have to start validation over from ground zero if I
want to upgrade to 5.0.7...
Perhaps the validation doc page could be updated with advice on proper

Tapestry 5.0.7 adds a new way of validating input from the client, a
validate event that is emitted from individual components and is
distinct from the validate event from the form. The event handler
method you already had, that was intended for cross-form validation
after values are in place, is being executed too early, for each
field.
Sorry, unexpected consequences. Perhaps the form's event should be
renamed from validate to formValidate?
Change your method name from onValidate() to onValidateFromForm()
(adjusting for your form's id).

Re: AW: AW: T5: determine button clicked in a beaneditor
you can use BeanEditor inside a normal form,
and add your own buttons, and then you can
check onSelected for your own buttons easily
I for enitity editing have a component
and throw new events based on button clicked;
then capture them
onEntitySaved(id, entity, isNew)
onCancel()
this way outside component need not know about buttons inside..
but can rely on event names..
When I have parent enitity form that embeds child entity form
I can then do:
onEntitySavedFromChildForm(id, child,isNew){
if(isNew) child.setParent(parent);
}
to generate your own event:
@Inject private ComponentResources _resources;
_resources.triggerEvent(entitySaved, new Object[]{_entityId,
_entity, isNew}, null);

Hi Angelo,
I guess the session.get(User.class, id) should happen in
onActivate or onSuccess (where I use it).
Just threat the onSuccess method as an atomic event handler
but onActivate should work also (not that sure).
Just print all the hits of the event methods to console and
see yourself. The order of the event should be:
1. onActivate
2. onSelectedXXX
3. onSuccess
I just use a schema like this in conjunction with a form
context:
onSuccess(int userId) {
User user = getUserById(id);
alterTheUserAccordingToForm(user);
storeUser(user);
}
Works very well.
Cheers,

hi martin,
yes, only to return a link:
void onSelectedFromUpdate() {
object = (Usr) session.get(Usr.class, id); // this is too late as
a object has been created this time
}
void onSelectedFromBack() {
System.out.println(from back);
}
Link onSuccess() {
return backLink;

Betreff: Re: AW: T5: determine button clicked in a beaneditor
Hi Martin,
The onSelected even happens after the form fields have been submitted,
my need is to edit a Hibernate bean, what I'm doing now is: I
persisted the bean's id, in the onActivate even I re-read the bean, so
that form will update an existing bean, however, even the cancel
button triggers onActivate event as well. so moving the re-reading of
bean to onSelectedFromUpdate seems a solution, but it's too late at
that time as form has been submitted, any idea ? Thanks,
A.C.
p.s. will be better if we can have an event before the form is
submitted, that is onActivate, but we have no way to determine which
button triggers the event there.

Hi A.C.
I asked the very same question before but in conjunction with
normal t:form component. Since the bean-editor is based on that
t:form component it should apply to this scenario as well:
Rule of Thumb: If you have a button you have an onSelected event!
So in your case:
t:form
input t:type=submit t:id=done value=Done/ input
t:type=submit t:id=failed value=Failed/ /t:form
class MyPage {
final int DONE = 0;
final int FAILED = 1;
int submitType = DONE;
boolean onSelectedFromDone() {
submitType = DONE;
return true;
}

Re: AW: AW: AW: T5: determine button clicked in a beaneditor
you can just call session.evict when cancel button is clicked..
that single line works fine for me

Hi Martin,
Your case should work as you have alterTheUserAccordingToForm. I'm just
taking advantage of Tapestry-Hibernate's feature to save coding, in the
first request, an object will be retrieved to render the form, in submission
the existing object was retrieved again then merge with the data in the
form, this saves the function similar to your alterTheUserAccordingToForm,
it works very well if we have only a submit button, getting complicated when
a cancel button is added.

Re: AW: AW: T5: determine button clicked in a beaneditor
if you have two buttons:
t:submit value=message:save
t:submit t:id=cancel value=message:cancel
in java code
@Inject private Session _session;
@Inject private ComponentResources _resources;
private boolean isCancel;
public void onSelectedFromCancel(){
isCancel = true;
}
public void onSuccess(){
if(isCancel){
_session.evict(_entity);//it is forgotten now
_resources.triggerEvent(cancel, new Object[0],null);
}else{
boolean isNew = _entity.getId() == null;
_session.saveOrUpdate(_entity);
_resources.triggerEvent(entitySaved, new
Object[]{_entity.getId(), _entity, isNew},null);
}
}
this way your component gives more information on what happened
and parent component can add extra logic I've mentioned before
onEntitySaved(id, entity, isNew)
onCancel()
I've actualy encapsulated all this into a Generic component
so in my impl there is extra code using TypeCoercer for translating entity id
for some operations.

Re: AW: AW: T5: determine button clicked in a beaneditor
as said,
just like any event
you declare a method properly named
for example form fires prepare success event
and you capture it by declaring in enclosing component:
public void onSuccess()
or
public void onSuccessFromMyForm()
so to capture entitySaved event
just declare
public void onEntitySaved(Long id, MyEntity entity, boolean isNew)
or for cancel
public void onCancel()

Re: T5: 5.0.10 new features
I've struggled with many internal classes to see how generic
components could be achieved,
but after failing to find simple way to pass generic declaration to component.
I found a way to do it from inside the component,
but it works only for components, not for pages...
I'm still looking is there a real bebefit from this...
If this is helpful for you,
I can give you the snippet ...

Hi Howard,
This is a very nice feature, in my app, I have many small tables, say 30, so
to edit those 30 objects I have to create 30 page classes without template,
that's a big saving. I'd like to save further, is there a way that we can
create a generic page class that can be called from other pages? if this is
possible then we save another 30 page classes. if this is not possbile I am
thinking of 'embedding' the edit class in a main page class, say:
// main page class for applicants
public class AdminApplicant {
// nested page class for the AdminApplicant.tml to call edit objects
public class Edit extends EditPageApplicant {
};
}
but the embedded Edit class is not visible in the AdminApplicant.tml, is
there a way to make this works?
Thanks,,

To be more specified,
you can define a base class:
package com.myapp.base;
public class EditPageT {
@Persist private T _object;
public T getObject() { return _object; }
public void setObject(T object) { _object = object; }
. . .
}
So you can create a page that can edit an arbitrary object. EditPage
will have its own Tapestry template containing, say, a BeanEditForm.
Now, you can define a new class:
package com.myapp.pages;
public class EditAccount extends EditPageAccount
{
}
EditAccount will inherit logic and template from EditPage.
Further, the getObject() and setObject() properties will be bound to
the type Account. This takes some doing, as the type of property
object of class EditPage is nominally java.lang.Object (due to type
erasure). However, Tapestry does a bit of work with reflection to
deduce the effective type of the property (Account).
This is a very, very high level of reuse ... and once again, we are
leveraging Java's type system to help us, rather than traditional Java
coding where we spend our time appeasing the type system.
