Re: Chinese can not display correctly

[dhning]

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

T5: addScript with @ symbol problems

[Martijn Brinkers (List)]

I am having some hard time using addScript. I am using PageLinkPopup
component which adds some javascript. It works just as long as I do not
add the @ symbol to the context parameters. The @ symbol is converted to
%40 and the following script is added with addScript:

new pageLinkPopup("pagelinkpopup", "user/edit/m.brinkers%40pobox.com",
"edit user", "width=600,height=300");

But, this results in:

Render queue error in BeginRender[Users:pagelinkpopup]: Conversion = 'p'

Somehow Tapestry chokes over the %40 or something.

I saw a bug posting by Chris Lewis
https://issues.apache.org/jira/browse/TAPESTRY-1818 which seems kind of
similar but I'm my Tapestry knowledge is not deep enough to see what I
do wrong.

Hope someone can help

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

[Thiago H. de Paula Figueiredo]

I've faced the same situation more than once trying to build my own  
components that extend or slightly changes some existing T5-core  
component. For example, subclassing the Label component so it always  
ignores its body and generates the label name from the corresponding field  
id. That could be (almost) accomplished if I could override its  
afterRender() method  
(http://svn.apache.org/viewvc/tapestry/tapestry5/trunk/tapestry-core/src/main/java/org/apache/tapestry5/corelib/components/Label.java?view=markup).  
The only solution I've found yet was copying the original component class  
and then changing it.


Other examples are an ActionLink and a PageLink subclasses that have it's  
own activation context logic, having an object as parameter, not the  
context value itself. Again, I had to copy code instead of subclassing.


Question to Howard: instead of having package visibility, could the core  
components have methods with protected visibility? And could their fields  
hava protected getters, so component subclasses can access superclass'  
parameter values? Or the current situation is the best one?


Thank you very much in advance.

T5: clearing BeanModel properties

[Andy Huhn]

Hello,

It seems that if I create a BeanModel using 



BeanModel toReturn = _beanModelSrc.create( MyObject.class, false,
_cmpntRsrcs );



Things work as they should - I can then use the properties in the
BeanModel, as I expect to.

But, if I first clear all properties from the BeanModel, and then try to
add them back one-by-one, I receive an error:



BeanModel toReturn = _beanModelSrc.create( MyObject.class, false,
  _cmpntRsrcs );

toReturn.exclude( (String[])toReturn.getPropertyNames().toArray(
  new String[0] ) );

toReturn.add( "pstlCode" );



Here is the error I receive:

Unable to locate a block to edit property 'pstlCode' (with data type
'null') of object [EMAIL PROTECTED]: There is no defined way to
edit data of type 'null'. Make a contribution to the BeanBlockSource
service for this type.



Any ideas?

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

[Chris Lewis]

I heartily agree with Filip. Even though the page name 'optimization' is
documented, I loathe the fact that I can do nothing to stop it. Please,
if this is implemented at least allow users the power to say 'yay' or
'nay' in our apps.

Chinese can not display correctly

[滕训华]

I use the ${message:labelKey} in the tml and define the labelKey in the
properties with Chinese characters,but when the page display ,the Chinese
can not display correctly. 

 

By the way,my properties file is define with UTF-8

Re: T5: Programmatically clearing the database on unit tests

[Mohan Zhang]

Ok, I got something that works now. Turns out the fancy contribution wasn't
even necessary. For those who might run into this problem, here's how I was
able to clear the database:

DatabaseInitializer.java

public class DatabaseInitializer {
private Session session;
public DatabaseInitializer(Session s) {session=s;}

public void clearDatabase() {\\clear your db here using session}
}

Then in your test, get a PageTester, say PageTester tester, and then simply
autobuild with the registry, like so:

DatabaseInitializer dbi =
tester.getRegistry().autobuild(DatabaseInitializer.class)
dbi.clearDatabase();

To be honest, I'm not sure why this works since DatabaseInitializer is
pretty POJO, but it's a pretty lightweight way to keep your dangerous
testing operations separate from your app if (like me) you are just learning
Tapestry IOC :)

Re: T5: Programmatically clearing the database on unit tests

Hi Daniel,

Thanks for the tip--it was very helpful. I was able to get this working
running my app in Jetty, but not when running my testng tests. I don't think
the modules are getting loaded the way I think they are. I'm using
PageTester, which claims

PageTester(String appPackage, String appName, String contextPath, Class...
moduleClasses)
  Initializes a PageTester that acts as a browser and a servlet
container to test drive your Tapestry pages.

I've tried adding various module classes but the
contributeApplicationInitialization code is still not being called. Any
ideas?

Re: Required parameters: also not null?

[Howard Lewis Ship]

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.

Re: T5: Programmatically clearing the database on unit tests

[Daniel Jue]

Try looking for
public class UserInitializerImpl implements ApplicationInitializerFilter {
...
 void initializeApplication(Context context, ApplicationInitializer
initializer){..reset your stuff in here..}
..
}


Then in your app module (or just the module you use for testing) contribute
that app initializer
like this:

/**
 * This is a initializer class that will be run when Tapestry starts.
 * @param configuration The registry's configuration
 * @param passwordEncoder built automatically and injected in
 * @param saltSource built automatically and injected in
 * @param session built automatically and injected in
 */
public static void contributeApplicationInitializer(
OrderedConfiguration
configuration,
final PasswordEncoder passwordEncoder,
final SaltSourceService saltSource, final Session session) {
configuration.add("UserInitializer", new UserInitializerImpl(
passwordEncoder, saltSource, session));
}

The example above shows how you can pass in things like a session, etc.  Of
course this is not always needed.

As already posted we gave a Tapestry 5 talk today. Approximately 80
attendees were there. The people seemed to be excited about Tapestry 5.
We've got a very positive feedback after the talk. Let's see if these
attendees will join the mailing list.

We will publish the slides and some pics in the next days.

It was also very nice to meet nille hammer (a member of this list) whose

I have a scenario where I am creating multiple actionlink in a loop. But I
want to use the same id for all the actionlinks.

Test.jsp


 rank
${student.rank}
 


So in my Test.java I have

Object onActionFromRank(final long _ student)
{
Now here I am getting student.id but I also want selected rank. I don’t
know how to get selected rank from .tml. This is not inside form.

T5: Programmatically clearing the database on unit tests

[Mohan Zhang]

Is there anything in Tapestry 5 that makes it easy to programmatically clear
the database? I'm unit-testing my DAOs and it'd be cool if I could write an
@BeforeMethod that clears the database. I suppose I could always write a
TestDao that encapsulates these operations, but I just thought I'd check in
case anyone had come up with a better way. I noticed that a lot of what's in
tapestry-test deals with the front-end.

Re: Required parameters: also not null?

[Matt Kerr]

the 'value' proposition you mention is forward compatibility, no?

i guess if fwd compatibility is not a concern - sure, do whatever.

T5 Altering IE's Conditional Comments... bug or feature?

[Christopher Heriot]

Using IE's conditional comments such as results in spaces inserted on
the inside of the html comments. I've been working around this with a
component that wraps its body in the appropriate condition using
MarkupWriter.writeRaw, but that seems like a hack. Is this intended
behavior that provides a benefit I'm not seeing or a bug I should
report?

A previous thread
(http://www.nabble.com/T5%3A-IE-conditional-not-working-under-template-td17094267.html#a17098807)
mentions this having been reported in Jira and closed, but I've been
unable to find the issue.

For example, a template containing this:
@import
'css/ie7.css';
results in the client seeing
@import
'css/ie7.css';

Thanks,

I'm unable to set showEffect and some other properties (see my original

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

[Lance Java]

Could returning null be built in as default behaviour? Since returning a
block from a non-xhr request is an error case, it would save putting checks
throughout the code and I can't see it breaking anything.

Cheers,
Lance.

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

[Howard Lewis Ship]

For full graceful degradation, you can inject the Request object can
check its isXHR() method, then decide on an appropriate return value
(typically, a Block or null).

Re: Required parameters: also not null?

[Howard Lewis Ship]

True, my concern is that we'll find that every use of required=true
also has acceptNull=false, in which case we add complexity without
providing value.

it's not uncommon to have a null param - dunno why it would be

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

Events from select component

[Brendan McNichols]

Hi all,

 

I have a  component on a page and I need to know when the user
changes its value.  I presume that I need to implement an event handler
as described in:
http://tapestry.apache.org/tapestry5/tapestry-core/guide/event.html, but
I tried to do that and wasn't able to get it to work.  Is this the right
approach?  Can anyone point out an example or let me know how to
implement this behavior?

 

Thanks very much,

Brendan

Your above template snippet would be interpreted by Tapestry as "the  
context parameter will be given by a call to the getSOME_CONSTANT() method  
in the page class", as prop is the default ActionLink context parameter  
binding. ;)


You could try context="literal:SOME_CONSTANT", but you would lose the  
correct Enum constant check here. If you type the wrong constant name, you  
would only see this error during run time, not compile time. And I do like  
to have the most things possible checked in compile time. It's putting the  
compiler to do work for you. ;)



onActionFromSomelink(EnumType enum) {
   // i'm expecting auto coercion to do it's job here
}

Where EnumType is the type of your enum.


It will work like that, but you need to correctly pass an EnumType value  
to the ActionLink's context parameter first.

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.

I'm a newbie but I notice tapestry has a StringToEnumCoercion.
What hapens if you do this?

Required parameters: also not null?

[Howard Lewis Ship]

I've been thinking of a change to how component parameters work.

Currently, the required attribute of the Parameter annotation
indicates that a component parameter must be bound (either explicitly,
or to a default).  It makes no assurances that it is bound to a
non-null value.

I'm  considering changing that, so that there would be a null check
for component parameters that are required, with an immediate failure
if the value bound to a required parameter is null.

The question is:  is this a destabilizing change?  Has anyone written
components with required parameters that are allowed to be null?

[T5] EventLink generate FileNotFound Warnings

[Kheldar666]

Hello Everybody,

I recently change some of my ActionLinks with EventLinks. Since that moment
I have that kind of errors :

-
For this URL :
http://127.0.0.1:8080/theorcs-main/index.layoutrenderer.portal.editmodelink:switchEditMode

I have this Warning :

18:30:09,726  WARN Credential:191 - EXCEPTION 
java.io.IOException: Syntax of file name, directory or volume incorrect
at java.io.WinNTFileSystem.canonicalize0(Native Method)
at java.io.Win32FileSystem.canonicalize(Win32FileSystem.java:395)
at java.io.File.getCanonicalPath(File.java:531)

(...)

18:30:09,729  WARN ResourceCache:251 - Alias request of

for
'file:/C:/Developpement/Projets/TheOrcs/theorcs-main/src/main/webapp/index.layoutrenderer.portal.editmodelink:switchEditMode'


It seam that when using an EventLink Tapestry tries to find a real file...
Is this normal ? The problem disappear with ActionLink. I tested on T 5.0.12
and 5.0.13, Jetty 5, Windows (vista)... Is this a JIRA issue ?

Regards,

Martin

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

[Lance Java]

I have solved the issue, I think I understand what was going wrong.
- Tapestry first draws action links as hrefs which cause a page reload for
graceful degredation
- Tapestry javascript magic then goes over all ajax action links and changes
them to javascript method calls
- I had a javascript error which stopped the tapestry javascript magic from
hapening, thus I was seeing the graceful degredation, thus no XHR's

Cheers,
Lance.

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

[Francisco Manzano]

Hi, I am inexperienced in Tapestry, but I had east problem recently:
You have like result a valid xhtml page? You can look for if you have 
"scripts of tapestry" inserted at the end of the page.

something  like this  :
...
type="text/javascript">
type="text/javascript">
type="text/javascript">
type="text/javascript">







If these scripts are not, you can have this problem., and you can solve 
it obtaining a valid xhtml like result.


I hope can help you
