Client validation occurs even when there is no t:validate

[Borut Bolčina]

Hi,

I am building a date input component with three select input fields
(day, month, year). Actually I am modifying the code from Alexander's
book. The goal is that the initial value of all three select
components are empty if the date parameter is not provided. Although
none of the t:select(s) has t:validate="required"

http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>





the html generated includes this piece of javascript at the bottom:



...so when I submit the form I get two error bubbles - one for day,
and one for year.

Any clues?


This is part of the custom component class:

public class DayMonthYearDateInput implements Field {

...
@Parameter(required = true)
private Date date;

private Calendar c = Calendar.getInstance();

@SetupRender
void setupCalendar() {
logger.info("setupCalendar() : " + date);
if (date!= null) {
c.setTime(date);
}
}

public SelectModel getDayModel() {
return new IntegerSelectModel(1, 31);
}

public SelectModel getYearModel() {
return new IntegerSelectModel(1960, 2010);
}

public SelectModel getMonthModel() {
return new EnumSelectModel(Month.class, messages);
}

public ValueEncoder getEncoder() {
return new IntegerValueEncoder();
}

public int getDay() {
logger.info("getDay() : " + c.get(Calendar.DATE));
return (date==null)?0:c.get(Calendar.DATE);
}

public void setDay(int day) {
c.set(Calendar.DATE, day);
}

public Month getMonth() {
logger.info("getMonth() : " + Month.values()[c.get(Calendar.MONTH)]);
return (date==null)?null:Month.values()[c.get(Calendar.MONTH)];
}

public void setMonth(Month month) {
c.set(Calendar.MONTH, month.getOrder());
}

public int getYear() {
logger.info("getYear() : " + c.get(Calendar.YEAR));
return (date==null)?0:c.get(Calendar.YEAR);
}

}


Thanks,
Borut

Re: hi, about the remotelink minixs

[Alex Kotchnev]

Nile,
  do re-read the T5 docs (e.g.
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/ActionLink.html,
 ), I think what you're trying to accomplish with your remotelink
mixin is
already being accomplished w/ zones:

Ajaxy goodness


   



   


then, in your code:

@Component
private Block updateBlock

public onActionFromFoo() {
   return updateBlock;
}

Re: apache configs to avoid subdirectory conflicts?

[Alex Kotchnev]

Michael,
   as you indicated, this sounds like an apache/ mod_jk issue that would
probably be better addressed at the relevant mailing list. You can still try
to post your specific mod_jk config here and maybe someone who has dealt w/
a similar config can advise you on the subject. As you indicate, if the
Tomcat only config works properly, the issue is probably not w/ T5.

   On a separate note, a more concise problem statement would probably help.
We do want to help, but it is sometimes difficult to read through a very
long description of the problem (it's much easier to move onto the next
message).

   One thing that you also note is that T5 is indeed case insensitive, while
apache isn't. Thus, if your Apache instance is configured to redirect
requests to /Admin to the T5 app, it would definitely not redirect requests
to /admin to the same app, unless explicitly configured to do so.

Cheers,

Re: T5: not all hibernate records saving

[Alex Kotchnev]

James,
   I am not sure if you've solved your problem, but it sounds like you might
have non-Tapestry related issues to deal with (e.g. Hibernate). If you still
feel that your problems are due to T5, please post some actual code (instead
of pseudocode) with a clear statement of your problem.

That's possible. Have a look at
   http://tapestry.formos.com/nightly/tapestry5/tapestry-ioc/coerce.html
esp. the section "Contributing new Coercions"







Example: I want to pass a User through activation context:

class User { private String name; private String password;...}

Registration{
...
public void onActivate(User user){...}

Re: Invoking a custom show javascript method for a Zone

[Alex Kotchnev]

Dave,
  I'm curious: what kind of hook would have been helpful for your
particular case? Tapestry, being a framework optimizes for the common
use cases, thus if your case is not i that category, it might be
somewhat more difficult (than the common cases and more difficult than
'no framework') . At the same time as a framework, it is also very
important for T5 to provide hooks for the 'not so common' cases so
that you don't have to hack it when you have a special need. T5 is
very good about the same on the server side (the ioc magic), not so
good on the client side, so it's important to note the difficulties...

It seems that such a similar thing is possible with

I think it would be really cool if such a thing would be included in 
tapestry out of the box.


Example: I want to pass a User through activation context:

Registration{
...
public void onActivate(User user){...}

}

as URL it could be serialized by tapestry as something like: 
http://domain/targetPage/paulpaulAtdomain

Tapestry and JPA/Spring transactions

[Jason Tan]

Is there a library/resource for opening and closing JPA EntityTransactions
per request like how tapestry-hibernate does? I discovered the wiki
pageon
integrating Spring's @Transactional so you could place it on a
setupRender( ), but I'm still unsure how you'd use that to encapsulate the
request (instead of just one method) -- the core problem here is that we
have ORM objects with associations that aren't eagerly fetched (because
they're @OneToMany). Thus, outside of the DAO service call (which is
annotated with @Transactional), the associations are null. We could use
eager fetching per-query or per-class, but I think the most natural fix is
opening and closing a transaction per request. Ideas?

Thanks,
Jason

Tabindex and accesskey in BeanEditForm?

[leechj]

Hello,
I was wondering if there was an easy way to add properties to fields in a
BeanEditForm.
Our application needs "tabindex" and "accesskey" in all fields in order to
comply with federal rules dealing with accessibility. Is there a way to add
these 2 properties to the fields in the form or should I just create the
form by hand instead of using BeanEditForm?

Thanks for any help!

Manuel, please post you updated code here because the one in the first

Thanks. Adding @Persist made the trick. But I think I will go for the

5.1.0.1-SNAPSHOT submit context not workin in a loop

[Ville Virtanen]

Hi,

I'm getting weird behavior here, it seems that the submit component is not
getting the right context anymore to the event handler when used in loop.
I've double and triple checked that I only have one consistent set of T5
libraries when the project is run, also the value encoders are there and
from what I can tell working correctly.

If I use the old "use a hidden field" method copied from howtos wiki,
everything works ok.

Is anybody else getting this? Is something else changed that could affect
this?

Correct; you need a separate process; Tapestry is configured quite
differently for templating/mailing than it is for normal, interactive
behavior.

 Hi,

 for sending out emails I need templates. Is there an internal tapestry

 to solve this (currently .tml are bound to pages/components). Is there a

Re: Tapestry 5.1: Wait for Page

[Howard Lewis Ship]

It only affects Ajax links; they must explicitly add an onclick event
handler attributes. Beyond that, the behavior can be changed by
monkey-patching the JavaScript and the CSS.

This encoding is done by the org.apache.tapestry5.services.URLEncoder  
service. You can write your own and override the default Tapestry one  
using alias overrides:  
http://tapestry.apache.org/tapestry5/guide/alias.html.



Should Tapestry use RFC 2396, as java.net.URI does?


Until some minor versions ago, that's what Tapestry used. Maybe it should  
present some easy way to choose one or another.

cross field validation with empty fields

[Ivano Luberti]

Hello, we are using T4.1
We have to validate a form and we don't want to do it client side.
Let say we have three text fields.
The validation should implement the following rule:
if (fielda="") && (fieldb="" || fieldc="")
 then throw new Exception("");

The problem is that we cannot link the validation to neither field
because they can be empty and the custom validator we are trying to
implement is nevere called if the field is empty.
We tried to  follow the Identity validator but it is also not called
when the field to which is associated is empty.

Is there another way to accomplish cross field validation ?

It seems to us that in T4.1  lacks a validator attribute for the form
component.

Encoding in activation context

[Fernando Bellas Permuy]

Hi!

I am implementing a simple service that returns XML (a RESTful service 
invoked by GET) as a Tapestry 5 page. That is, the associated template 
(.tml) does not return HTML/XHTML, but XML. I have used the @ContentType 
annotation on the page class: @ContentType("text/xml"). All is working 
fine. To my understanding, Tapestry does not provide any specific 
support to implement this kind of services. However, the usual page 
support should be enough for GET/POST requests (I am only interested in 
GET requests by now).


The page has an activation context. The activation context represents 
the parameters of my service. To simplify my question, consider that the 
service requires two parameters: category and keywords. Since Tapestry 
embeds the activation context inside the URL's path, to invoke my 
service by GET, the client must make a call to a URL like:


http://.../myservice/<>/<>

e.g. (category=40, keyworkds=Java)

http://.../myService/40/Java

Let us suppose "keywords" contains blank characters, like for example 
"The Java Programming Language"


Experimentally, I have observed that the client must use the following URL:

http://.../myService/40/The$0020Java$0020Programming$0020Language

That is, blank characters must be replaced by $0020. Other non-English 
characters (e.g. latin characters like ñ, á, etc.) must be encoded.


I understand that Tapestry encodes the activation context by using 
org.apache.tapestry5.services.URLEncoder. Does this class follows some 
standard encoding mechanism? - In my case this is necessary, since the 
client is not Java, but .NET.


Should Tapestry use RFC 2396, as java.net.URI does?

Any advice for my client code?

Any other strategy to implement an XML service in Tapestry?

Thanks!

What you need is to implement a DataTypeAnalyzer, define two "Tapestry  
types" (in parenthesis because they're just a name) and provide edition  
blocks for them. And contributing your DataTypeAnalyzer to the  
DataTypeAnalyzer service:


public static void  
contributeDataTypeAnalyzer(OrderedConfiguration  
configuration) {
configuration.add("SomeIdJustUsedForSorting", new  
YourDataTypeAnalyzer(), "before:Default");

t:TextField and t:TextArea

[Luther Baker]

Is there a global way to explicitly set or override *html *(non-CSS)
attributes on tapestry components like textfield and textarea?

For instance, in one particular app, I have to override almost all of my
components with t:Parameters that define slightly custom sizes for these:

textfield: size="106" maxlength="105"
textarea: cols="80" rows="4"

But in my case, these custom sizes apply to 90% of the fields in the 15
forms.

Have you any idea?

HTTP does not automatically warns the server that the page was closed
or the user clicked any browser button. Given that, your solution is
JavaScript.

I would suggest @Persist("flash"): the field is put in the session and
then removed after it's read the first time. ;)

Manuel, please post you updated code here because the one in the first

Re: Tapestry 5.1: Wait for Page

Will this be configurable? While it can be a useful feature, there are 
times where clicking a link (etc) before the page is ready won't break 
the app. Additionally, I get a little freaked out at any non-essential 
feature I can't control. So, will it be configurable?

Re: [T5 5.0.18] java.lang.IllegalStateException: Cannot create a session after the response has been committed

[Angelo Chen]

I have same error, the reason is, I have a filer to trim off the long
jsession IDs from url, solution was, I stopped using invalidate in the T5
side. however, according to Peter, this happens when you have a sendRedirect
without a matching return true in a dispatcher, you can try that.
