It's just a warning, not an error, you can safely ignore this one.

Javassist exception on deploy time

[Martijn Brinkers (List)]

Hi,

I get this long Javassist exception when I startup Jetty from within
eclipse. This only happens when I start Jetty with the Tapestry projects
as a dependend project.

Any idea?

T5： Hibernate warning

[Angelo Chen]

Hi,

This is an old problem that I was not able to fix, applications runs, but
always get this error

[WARN] AnnotationBinder Package not found or wo package-info.java:
org.bfe.sample.t5.entities

I do have a hibernate.cfg.xml as follow and it works well:


  
com.mysql.jdbc.Driver




  


I do remember that somebody suggests putting a package-info.java in the
entitiies directory, but what needed to be listed?

Thanks,

Angelo

Re: [T4.1.5] Creating Tapestry links, client-side.

[Andreas Andreou]

It's usual to generate a direct link with a dummy parameter (like "{0}")
at the server and pass that to the javascript that when needed will replace
{0} with the dynamic parameter.

For forms, the @Hidden component (check also its encode parameter) is helpful

Hi all,

I wanted to know whether anyone else from this list had the  
opportunity to be in Düsseldorf yesterday.


Igor and Renat did a really good job showing how quickly and easily  
you get an application running with Tapestry 5. They have been  
given a hard time by the audience asking loads of questions. They  
have passed that with flying colours (I looked this up in a  
dictionary). They have left no question unanswered (well, maybe one  
or two ;-) ).


The only downside (as often with this kind of events) was the lack  
of time. A lot of topics had to be left uncovered. And could not   
be covered either in the session after the presentation. I  
personally would like them to follow up with events focussing on  
particular topics like Tapestry-IOC or the Contribution concept.  
Especially the latter one still is a bit obscure to me.


All in all I enjoyed the opportunity to meet some fellows from this  
list and even some open source celebrities personally. And free  
beer is allways a bonus. I hope to see some photos online soon. You  
guys get a vote +1 (non-binding) from me!

[T4.1.5] Creating Tapestry links, client-side.

[Jim]

Hello,

Is there a clean way to dynamically (on the client-side) generate 
Tapestry Direct/Service/Page links?  e.g. if you wanted to generate a 
link to a Tapestry listener, but you don't know the parameters until 
after the page is rendered, such as if you're generating links/behavior 
to attach to items that are retrieved via AJAX.


I could just "View Source", paste the URL, and hack it.  Or I could 
dynamically update the fields of a hidden @Form.  My concern, however, 
is that I'd be locking my application into that specific version of 
Tapestry -- it would be comparable to basing logic off of a class's 
toString() implementation.


I'm using Tap 4.1.5, though, so perhaps this is a reasonable risk since 
upgrading to Tap 5 would require a near-rewrite anyway?


Thanks,
Jim

Re: [T5] Return HTTP Error from AJAX Call

Re: What if "Page" was removed from page names?

[Alejandro Scandroli]

Hi Howard

I'm experimenting with this, I'm trying to get it to work for what it
could be Trails 2, and it was actually pretty easy to do.
I just needed to create a coercion for classes, and then provide
default pages: ListPage, EditPage and ViewPage. Way easier than what I
needed to do to make it work for T4.
Now I'm stuck with providing editors for relationships:

That's cool about your HTML designer; I always picture it as a pair
programming deal, with the coder running the app so that the designer
can view changes.

Re: What if "Page" was removed from page names?

[Howard Lewis Ship]

Eventually, I want tapestry-hibernate to hook in to thing such that,
if you don't define a page named "edit/blog" (for entity Blog), it
provides one for you. Ditto for "add/blog", 'view/blog" and
"search/blog".  But that's for 5.1 or beyond.

Re: New website using T5: www.ingamenow.com

[Daniel Leffel]

Hi Howard,
Absolutely happy to share.

We're running .12 because .13 happened too close to the release and we
didn't want to introduce any more changes. We're planning on moving to .13
at the next release.

There are 27 pages on the site, although the bulk of the functionality
exists on about 12 of them. The site is heavily componentized though - there
are 19 components we created and reuse throughout the site. Making heavy use
of components has really aided in the build and iterate cycle because of the
way that we isolated functionality within them - many of the pages are
nothing more than containers for lots of independent components.

There were 3 developers on the project working part time over the past 4
months. Much of that effort was in building back-end services, aim/gtalk
integration and statistics computation. I'd estimate that around 30% of the
effort was on the front-end and I regard that as a credit to T5 more than
the complexity of the back-end.

One fantastic point to make (which isn't unique to T5 but Tapestry more
over) is the fact that for our HTML/CSS developer, we actually were able to
give him SVN access and he, without Java experience (much less Tapestry),
was able to make pretty large modification to page and component layouts.
That was awesome to not have to bother Java developers with!

Danny

Re: Select model issue

[José Paumard]

Thank you Ulrich, you put me on the right track to solve the problem. 
Here is what I did precisely, just for the ones who'd need it.


In fact EnumSelectModel is final, so you cant extend it, but it's easy 
to build one, and T5 does all the work behind, esp. finding the right 
labels :


EnumSelectModel esm = new EnumSelectModel(BaseType.class, messages) ; // 
messages is injected by T5 IoC


then the options with the right labels can be accessed with :

esm.getOptions()

and the base types you dont want can easily be removed from this list.

José


Ulrich Stärk a écrit :


getValidBaseTypes has to return an Object which implements 
org.apache.tapestry5.SelectModel. If you want to filter out some enum 
values that shouldn't be displayed you could extend EnumSelectModel 
and overwrite the getOptions() method. In your own implementation make 
a call to the super class' getOptions() and remove the desired 
elements from the list returned.

This just comes to my mind, there might be a more elegant method.

Re: What if "Page" was removed from page names?

[Andreas Andreou]

Yep, uses a tiny annotation scanner lib that only scans
WEB-INF/classes (by default) at app startup time.

Can't really tell how this messes up with synthetic pages
cause i don't quite know what you have in mind... in our
current T4 project, we've been using synthetic components
though which (i believe) is an equally powerful concept and
has the benefit of not messing with page names.

How to have localized translators

[Ulrich Stärk]

Hi List,

I'd like my users to be able to input data in their respective locale. 
For example in most european countries you use the ',' to seperate the 
decimal places from the integer part of a number.
For a quick workaround I'm using a patched version of Tapestry wich adds 
 a Locale parameter to Translator's parseClient and toClient methods, 
but I don't want to apply this patch to every release of Tapestry.
One solution could be to write my own translators that have a setter for 
the current user's locale and instantiate them on every page where they 
are needed but this feels kind of cumbersome to me especially if you 
want to use BeanEditForm to edit some entity whith fields that should 
accept localized valus. In that case I also have to do a lot of changes 
to my templates in order to tell BeanEditForm to use my own translators 
instead of Tapestry's own.

How do you solve that?

New website using T5: www.ingamenow.com

[Daniel Leffel]

Guys,
I just wanted to pass along a site that we've just launched:
www.ingamenow.com. The site is best described as Twitter for sports and
sporting events. Users can interact over teams, players and games - most
notable, they can receive real-time scores and banter through Gtalk, AOL
Instant Messenger and email.

The front-end is Tapestry 5 making use of a few of the AJAX features. I
believe strongly that using T5 sped the development immensely and all
members of the teams are converts now.

The rest of the architecture is Spring + Hibernate.

Thanks to Howard and everyone who has helped make Tapestry what it is today!

Re: What if "Page" was removed from page names?

[Howard Lewis Ship]

I have a slightly clumsy way of accomplishing what I want today,
without changing the framework.

Instead of creating BlogPage, I create class blog.BlogIndex and
blog/BlogIndex.tml.  I can then refer to this page as "blog/index" and
it appears as "/blog" in URLs, which is what I want.

Except you lose some of the intrinsic simplicity of convention over  
configuration when you decide to offer both. Note that, depending on  
how it's implemented, this change need not break any existing  
Tapestry 5 applications. If the page class has a -Page suffix, then  
Tapestry would map to that. (You might have to throw an exception if  
Foo and FooPage both existed under the pages package hierarchy.)

On the naming issue itself, I think it would be a positive  
development. I think the historical convention of using entity-like  
names for pages is a regrettable fuzziness. I've shown Tapestry to  
some undergraduate students and a common beginner's mistake is to put  
code in a page class that really belongs in an entity class. The  
naming didn't help there. I'm sure something similar would apply with  
junior developers in a software house. There's very little point in  
making the hurdles any higher for people learning their craft.

To really set the cat amongst the pigeons (and infuriate the  
keystroke tax collectors), I think a similar mapping of a -Component  
suffix would be good for components (again optional). Although it's  
unfortunately a longer suffix, the conceptual clarity would probably  
be worth it. (Why refer to something as, say, an "account component"  
when discussing it but refuse to actually call it that. Because it's  
too long?)

Lastly, I don't think I would go along with Hugo's idea of list of  
optional suffixes. I can't imagine any sensible suffix for pages and  
components other than -Page and -Component. (Although that could just  
be my limited imagination.) :-)

Hi CG,

the inPlace attribute of the t:grid tag does what you are asking for. For

[T5] Grid paging refresh the whole document , can it be done in AJAX-way ?

[CG]

The T5 Grid compoment come with paging functionality , however,
whenever a click on the pager component , it will refresh the whole
page(document) instead of the grid area.

I wonder can it only refresh the Grid body rather than refresh the
whole page , maybe using  and  ?

Or any way we can override the existing function to archive that ?

Thanks.

Igor´s and Renat´s Presentation of Tapestry 5 yesterday evening in Düsseldorf

[nille hammer]

 
Hi all,

I wanted to know whether anyone else from this list had the opportunity to be 
in Düsseldorf yesterday.

Igor and Renat did a really good job showing how quickly and easily you get an 
application running with Tapestry 5. They have been given a hard time by the 
audience asking loads of questions. They have passed that with flying colours 
(I looked this up in a dictionary). They have left no question unanswered 
(well, maybe one or two ;-) ).

The only downside (as often with this kind of events) was the lack of time. A 
lot of topics had to be left uncovered. And could not  be covered either in the 
session after the presentation. I personally would like them to follow up with 
events focussing on particular topics like Tapestry-IOC or the Contribution 
concept. Especially the latter one still is a bit obscure to me.

All in all I enjoyed the opportunity to meet some fellows from this list and 
even some open source celebrities personally. And free beer is allways a bonus. 
I hope to see some photos online soon. You guys get a vote +1 (non-binding) 
from me!

Regards nillehammer

But in cases like mine, where the zone comes after the links in the markup
(which should be a quite common case) - the problem sadly remains, since the
name of the zone can't be determined before rendering it :-(

Re: 5.0.13 IE javascript error

[Sven Homburg]

here some ugly code sequences
hope that helps

example javascript class (SelectSwapper.js)

var SelectSwapper = Class.create();
SelectSwapper.prototype = {
  initialize: function(selectComponentId, linkId)
  {
this.selectComponent = selectComponentId;
this.linkId = linkId;
this.selectedValue = "";
Event.observe($(this.selectComponent), 'change',
this._change.bindAsEventListener(this));
Event.observe($(this.linkId), 'click',
this._click.bindAsEventListener(this));
  },
  _change: function(myEvent)
  {
this.selectedValue = $F(this.selectComponent).trim();
  },
  _click: function(myEvent)
  {
if (this.selectedValue.length() > 0)
{
   $$('.Artifact-type-').each(function
show(object){object.style.display='block';});
   $$('.Artifact-type-TASK').each(function
show(object){object.style.display='block';});
   $$('.Artifact-type-PERS').each(function
show(object){object.style.display='none';});
   $$('.Artifact-type-LEAR').each(function
show(object){object.style.display='none';});
}
  }
}

than add this to you page/component class
@IncludeJavaScriptLibrary(value = {"SelectSwapper.js"})
public class BlaBlaBla
{
@Environmental
private RenderSupport _renderSupport;

@Component
private Select mySelect;

@Component(parameters = {"element=a", "href=literal:#"})
private Any myLink;

void afterRender(MarkupWriter writer)
{
_renderSupport.addScript("new SelectSwapper('%s', '%s')",
mySelect.getClientId(), myLink.getClientId());
}
}

empty block in grid - how?

[Udo Abel]

Hi,

I wanted to define a message as a replacement of the default empty-message in 
the Grid component, but I could not find any hint on how to define such a 
block. Casting the parameter to "message" or "literal" does not work.

Btw., I think the documentations lacks some essential information. E.g., I 
searched the internet quite a while in order to find out how an "onclick" 
handler can be called from a Link. Just by chance I came across an example from 
which I concluded that any parameter of a PageLink not interpreted by Tapestry, 
is literally taken into the  tag. Another example is the "context" 
parameter, for which the documentations says that it can be an array - but 
there's no explanation whatsoever on how one can define it as an array. Again, 
only after long searches I found that there is a list: prefix, that regrettably 
isn't part of tapestry yet.
I'm sure, the authors of the documentation are just too familiar with tapestry 
to recognize that a new user just don't know HOW to do it, when they say e.g. 
"define a block".

Regards,
Udo.

Re: Re: What if "Page" was removed from page names?

[nille hammer]

Hi list,

to answer Howard´s question, yes I would like that feature. Exactly as 
described. At the moment I prefix my page class names with the package name. I 
am not happy with that. I´d prefer to suffix them with "Page".

And my opinion to the discussion whether generation of urls should be 
configurable. I think it should NOT be configurable. The mechanism is good as 
it is.
1.) The generated urls serve the important purposes like being bookmarkable, no 
request-parameters etc. That is what is important about an url.
2.) I could imagine matching a class name to a small set of predefined values 
might be a bit easier than to something dynamically configurated. This might 
even ipmacht performance. Although surely not much and only at startup time. I 
haven´t looked into that part of the source code though.
3.) None of my customers really cares about how urls look like. Let it be 
"blogger", "myblogger" or "mybloggerpage". I am sure if you asked your 
customers, they would not be able to tell what the url is.  If we are honest, 
the desire to make url generation configurable ist to give us developers 
something else to play with.

Tapestry is behaving exactly as it should. For any request, the Tapestry  
servlet filter (it is not a servlet), checks if the request can be handled  
by it. If it cannot, it just ignores it, giving a chance to other servlet  
filters and servlets to process the request.


Having an Index page, Tapestry receives a request to /broker and thinks  
that "broker" is the activation context for the Index page.


You can leave your Index page and tell Tapestry to ignore requests to  
/broker adding this lines to you AppModule:


public static void  
contributeIgnoredPathsFilter(UnorderedCollection configuration) {

configuration.add("/broker/.*");
}

Thanks Sven, but what exactly are you referring to?

If you are referring to the use of RenderSupport for javascript, then I
should explain a bit.

I have already had to make various changes in my Layout classes etc to
assure they work with the move of the javascript to the bottom of the page.
The last problem I faced was that the onchange on some of my select items
use prototype and were run (causing javascript errors in IE) before
prototype.js is loaded. To fix that, I explicitly refer to prototype in

Re: What if "Page" was removed from page names?

[Andreas Andreou]

I'd really like to suggest an approach similar to the UriTemplate annotation for
T4 pages that's included in tacos...

See 
http://fisheye3.atlassian.com/browse/tacos/tacos-4.1/trunk/tacos-annotations/src/java/net/sf/tacos/rest

It even supports aliases, so, no worries if you decide to change names
and still want to old bookmarks - just use:

@UriTemplate(value="index", alias = {"home", "default"})
public class Home { ... }

Re: [T5] About core components subclassing and methods with package visibility

[Yunhua Sang]

I have same pain with you, Thiago. It's not easy for subclasses to
access parameters in parent classes.

Delegation works perfectly, but you have to copy all parameters from
parent component.

Re: t5: Returning block works in Firefox but not in IE

[9902468]

Better yet:

Tapestry could be so smart that it would return null even if the handler
returns block if the request is not ajax. 

if(return_value == block && is_not_xhdr){
block = null;
}

That wouldn't break anything?

Re: What if "Page" was removed from page names?

[Lutz Hühnken]

Shouldn't that be up to the developer (or whoever decides on the
URLs)? If you don't want the page suffix, why not just name the page
"Blogger" instead of "BloggerPage"? What if I wanted a url that reads
"mypage"? Would I have to name the page "MyPagePage"? I'm all for
convention over configuration, but here I feel some arbitrary rule
would be unnecessarily imposed on the developer.

Just my two cents,

Re: [t5] form method="get", "old school" query parameters

[Kristian Marinkovic]

hi lutz,

by default the tapestry form will generate method="post". 
there is no way to change the method... you could add a 
jira issue to change the form component to accept an 
additional method parameter.

alternativley you could create a mixin that is attached to 
your form. The mixin could then overwrite the method 
property:

public class FormMethodOverrideMixin() {
..
public void afterRender(MarkupWriter writer) {
Element form = // get element representing from tag
form.forceAttributes("method","get");
   }
}

g,
kris

As long you don't want or need to process this form in T5's way (with 
event handler methods, binding HTML fields to values, etc), just don't use 
 
T5's Form component and use an ordinary HTML form.

I think the "OnEvent" mixin from t5components does what you are looking for:

[t5] form method="get", "old school" query parameters

what is the way to create a form with method="GET" in Tapestry 5?

I would like to create a simple form that produces a "GET" request
with query parameters, such as
www.example.com/books?author=king&category=crime. What is the
straight-forward way to do that?

Thanks for your help,

reason for adding js libraries at the end of the document:

https://issues.apache.org/jira/browse/TAPESTRY-2364

you could write an own Flash component that adds the js
libraries into the head section:

public class Flash() {

  beginRender(MarkupWriter writer) {
  Document d = writer.getDocument();
  Element head = d.find("html/head");

  head.element("script", ...);

Re: T5 5.0.13 Javascript rendering at end of document - questions regd







Filip,
   That will not work because 1) the Flash player javascript is called
in-line to render the Flash player and 2) within the flash player
javascript, I've got some dynamic parameters being added. I can rework (2)

to make it a function parameter and put the dynamic nature in the inline
function call but that will still fail. Here is why:



   
   HTML tags 

renderFlashPlayer(${myParam}) 

   Other HTML tags ...


   
   
   


So if renderFlashPlayer lives in flashPlayer.js, it will simply not work!
My
only alternative is to manually include flashUtil.js in the header and
inline flashPlayer.js. This is unnatural and against the grain. I suspect
that there are other similar scenarios.

Actually, you can just put the JavaScript in a .js file and then include



it with @IncludeJavaScriptLibrary. Then add a call to
RenderSupport#addScript in your page's afterRender handler that does the



setup you need.

For this and more, check
http://tapestry.apache.org/tapestry5/tapestry-core/guide/ajax.html.

One more addition: When including the flash player in a page, the
recommended technique is to put inline javascript that renders the

an external javascript file being included. If I do an asset injection

of

the Flash javascript, it ends up at the bottom of the page and the

flash

player inline javascript fails. So it seems like one would need to
override this behavior. Otherwise I'd have to package up the inline
javascript as a method, inject that and then call it in place. But I'm
concerned with putting all the javascript for the flash in a Java file.



That is not a natural fit.



I have some questions regarding the decision to render Javascript at

the

end of the document:

1) What was the rationale/dirver for this?
2a) The upgrade notes say to use RenderSupport. Can anyone provide a
short description of how to use RenderSupport to inject a simple
javascript function?
2b) This implies that a lot of inline javascript will have to be moved



from .tml to .java classes. It seems this will reduce the

"naturalness"

of being able to use javascript normally.

Re: dynamic link in actionlink

[Geoff Callender]

Alternatively, if you like this kind of syntax
context="list:student.id,student.rank"
then contribute a ListBindingFactory to AppModule as described in http://wiki.apache.org/tapestry/Tapestry5HowToAddBindingPrefix 
 .

Re: T5 5.0.13 Javascript rendering at end of document - questions regd

[Kristian Marinkovic]

reason for adding js libraries at the end of the document:

https://issues.apache.org/jira/browse/TAPESTRY-2364

you could write an own Flash component that adds the js 
libraries into the head section:

public class Flash() {

   beginRender(MarkupWriter writer) {
   Document d = writer.getDocument();
   Element head = d.find("html/head");
 
   head.element("script", ...);

   }
}

i think you get the idea

Filip,
That will not work because 1) the Flash player javascript is called 
in-line to render the Flash player and 2) within the flash player 
javascript, I've got some dynamic parameters being added. I can rework (2) 

to make it a function parameter and put the dynamic nature in the inline 
function call but that will still fail. Here is why:




HTML tags 

 renderFlashPlayer(${myParam}) 

Other HTML tags ...







So if renderFlashPlayer lives in flashPlayer.js, it will simply not work! 
My 
only alternative is to manually include flashUtil.js in the header and 
inline flashPlayer.js. This is unnatural and against the grain. I suspect 
that there are other similar scenarios.

Actually, you can just put the JavaScript in a .js file and then include 
it with @IncludeJavaScriptLibrary. Then add a call to 
RenderSupport#addScript in your page's afterRender handler that does the 
setup you need.

Re: T5 5.0.13 Javascript rendering at end of document - questions regd

[kranga]

I take that back. Putting the flash player inline javascript in a method 
will not help since when it is called, the flash player external javascript 
will still not have been processed. So now I'm forced to statically or 
conditionally include the flash player javascript in my layout at the top. 
This defeats the goal of allowing components to contribute javascript to a 
page.


I think a mechanism to override the inclusion of javascript at the bottom of 
the page is needed. There are far too many javascript utilities that have 
been written that will fail to work in the mode. And I suspect almost all 
inline-rendering techniques that depend on an included javascript file will 
fail.



One more addition: When including the flash player in a page, the 
recommended technique is to put inline javascript that renders the flash 
player where the javascript appears in the page. The javascript relies on

As long as it's configurable, I'm fine with it. :)


Except you lose some of the intrinsic simplicity of convention over  
configuration when you decide to offer both. Note that, depending on  
how it's implemented, this change need not break any existing  
Tapestry 5 applications. If the page class has a -Page suffix, then  
Tapestry would map to that. (You might have to throw an exception if  
Foo and FooPage both existed under the pages package hierarchy.)


On the naming issue itself, I think it would be a positive  
development. I think the historical convention of using entity-like  
names for pages is a regrettable fuzziness. I've shown Tapestry to  
some undergraduate students and a common beginner's mistake is to put  
code in a page class that really belongs in an entity class. The  
naming didn't help there. I'm sure something similar would apply with  
junior developers in a software house. There's very little point in  
making the hurdles any higher for people learning their craft.


To really set the cat amongst the pigeons (and infuriate the  
keystroke tax collectors), I think a similar mapping of a -Component  
suffix would be good for components (again optional). Although it's  
unfortunately a longer suffix, the conceptual clarity would probably  
be worth it. (Why refer to something as, say, an "account component"  
when discussing it but refuse to actually call it that. Because it's  
too long?)


Lastly, I don't think I would go along with Hugo's idea of list of  
optional suffixes. I can't imagine any sensible suffix for pages and  
components other than -Page and -Component. (Although that could just  
be my limited imagination.) :-)

Re: What if "Page" was removed from page names?

[Hugo Palma]

I also agree.
Maybe this could take the form of a configuration property. You could 
specify a list of optional suffixes for page/component names.
When configured, you could either access the page/component by it's 
complete name or by it's stripped version.

directory and can see the java class has been compiled and placed in the
correct directory, just the changes are not reflected until I re-boot the
server, any idea why? Thanks.

dynamic validation

[Joachim Van der Auwera]

I have a page which contains an input component for which the limits 
should be determined at runtime. Does anybody know how this can be best 
achieved?


I tried something like the following in my template

t:validate="min=${value.MinimumValue},max=${value.MaximumValue}"/>


But this fails.

Any ideas?

Thanks,
Joachim

Re: BeanModel and complex types?

[Kristian Marinkovic]

hi udo,

you have to  contribute the child property type to the 
DefaultDataTypeAnaylzer
so the BeanModelSource will not ignore it

public static void contributeDefaultDataTypeAnalyzer...{
   configuration.add(MyType.class,"myType");

take a look https://issues.apache.org/jira/browse/TAPESTRY-2460
it has two examples how to display a complex child property with another
block (containing another BeanEditor)

g,
kris

Thema
BeanModel and complex types?







Hi,

in many situations I have objects containing other objects as fields, 
resulting from a 1:1 reference in a database. E.g., an employee has a 
refrence to the subsidiary where he is working.
In those cases I want to display the name of the subsidiary in a Grid 
component.
The property can be accessed by something like
employee.getSubsidiary().getName();

Is there a way to extend the BeanModel to access those properties?
Or do I have to duplicate all fields from complex types in simple fields 
at the top level object, like
employee.getSubsidiaryName();
?

Thanks,
Udo.

Hi,
  You should first utilize native2ascii(in jdk/bin) to convert the
appname_zh_CN.properties to asc, then it should solve your probelem.
  I don't know why T5 deal with internationalization differently from T4. In
T4, we developer don't have to convert the resource files, we just need
input Chinese and it displays correctly.
  
  And if your IDE is eclipse, you can find some plugin to help you convert
encoding automatically.

Thanks!

DH

Re: programmatic component rendering

[Udo Abel]

Thank you for your hints - 
I'm very new to Tapestry, so I need to do some experimenting to get the 
concepts right.
As a traditional servlet programmer, I would want something like
Component.render(writer);
but that would of course be incompatible with the framework.
Nevertheless, the framework itself must do the trick, since it invokes the 
components in a template somehow.
Because of that and the documentation, which states for the 
BeforeRenderTemplate Phase: 
"This phase exists to allow a component to decorate its template...",
I thought there might be  way to dynamically change the template at that point.

Regards,
Udo,

Re: Required parameters: also not null?

[Kristian Marinkovic]

don't forget the BeanEditorForm... object may as well be null

Re: Required parameters: also not null?







Working on this now, and there are plenty of cases where a binding is
required but the value may be null; for example, TextField (the value
may initially be null, but must be bound).

 Agreed 100%. Required = some value must be given to the parameter. 
Not
 null = some not null value must be given. Required != not null.

 We could add some like this to @Parameter and support it in 
tapestry-core
 easily:

 boolean acceptNull() default true;

 Then anyone writing components would get the automatic null value 
checking
 if wanted or needed without disrupting old code or changing how 
parameters
 work.
