Upgrade from T4 to T4.1: Javascript problem
Hi, I was just trying to upgrade from T4 to T4.1 (4.1.6). When Javascript is enabled, the page will be blank. With Javascript disabled in the browser, the page renders just fine. I replaces the ajaxDelegate in the Shell component with an empty render method. This works, but of course I get Javascript errors, that Tapestry is not defined. I'm not sure why the Page is blank. I guess that Tapestry hides the content and waits for the whole DOM tree to be available before it shows the content, but the last steps fails. Can this be?

[T4] Validation Problem
Hi, I'm using a required validator on a TextField and use the form delegate to check whether there is an error in the TextField. If so, I render an error message. However, this message is rendered before the input-field is rendered. The problem starts when I have this TextField in a For loop. Now a validation error message is shown an the next TextField, instead of the TextField that really has the problem. Interestingly, if the last TextField is wrong, the first TextField gets the error message. Anyone knows a solution?

Re: Only one user request at the same time
Hi Quoting spot_ [EMAIL PROTECTED]: how can I make shure, that only one request of a user is processed at the same time. In other words: I want to dismiss a request of a user, if a request of the same user is already running at the moment. There is no clear answer to this question. And you probably have to think hard about what you really want to achieve. To prevent a form to be submitted twice, you could use a ticket service. This would also prevent to have the form to be submitted again, even if the first request has been completely processed. But it would not help against having two different forms submitted at the same time (without having substantial additional logic in the ticket service). But I think you are trying to implement logic at the wrong level. The underlying services need to be able to cope with concurrent requests. A resulting error can then be reported back to the user.

Re: i18n in javascript
Quoting learner [EMAIL PROTECTED]:
onclick=javascript:return confirm('${message:key_in_my_property_file}');
i try to use key in javascript like above but failed.
how to use key in javascript?
There are several thing to consider here.
1) You cannot use the message service directly from Javascript, but
you can create Javascript with the message service (the difference is
subtle, but important).
2) I do not know of any ${message: } notation (which Tapestry version
are you using?) I only know the message: prefix binding, which is not
usable here.
3) If you are using this in a template, you must use the ognl: prefix.
Try the following:
a jwcid=@Any onclick=ognl:'javascript:return confirm(\'' +
messages.getMessage('key_in_prop') + '\')'
Or for less confusing string escapes do:
a jwcid=@Any onclick=ognl:myLocalizeJavascript
And in the corresponding class:
---
@Message(key_in_prop)
public String getJsMessage();
public String getMyLocalizedJavascript() {
return String return confirm(' + getJsMessage() + ');
}

Christian

[T4] Event for every request to clear data
Hello, currently, we have a bean that is registered for a lot of pages which holds some information that is only releveant for the scope of the request. So I thought it woule be more appropriate to make an ASO out of it with scope request (which does not exist). The reason behind this is the fact, that this object realy is used for inter-component and -service communication. So I thought about making this an ASO with session scope and registering a service to a listener that fires at the end of a request to clear the data. So is there something analogous to ResetEventHub? Or am I looking in the wrong direction here? Thanks.

I do not really understand what you are doing, but there are different
ways to manipulate state according to elements in a For loop.
Assuming you render something like a button for each element, you
could use the current value (assigned via value) or the index
(assigned via index parameter) to associate the rendered button
with the element, so you know for which element the button has been
pressed.
Another way, if things are more complicated, is to use hand tailored
setters and getters which take into account what the current element
in the loop is, backed by a persisted property.
Lets say you have a property elementChecked (a set) and iterate
with the For component over elements:
span jwcid=@For source=ognl:elements value=ognl:element
...
/span
In this component you have a checkbox accessing a property elementCheck.
For this property define the getter and setter as follows:
public boolean isElementCheck() {
this.getElementChecked().contains(getElement());
}
public void setElementCheck(boolean checked);
if (checked) {
this.getElementChecked().add(getElement());
} else {
this.getElementChecked().remove(getElement());
}
}
Well, elementChecked does not need to be persistent, if you do not need
it after the rewind.

That's not too hard. You can follow these instructions: http://wiki.apache.org/tapestry/Tapestry4Spring (we basically used this approach (first variant) in our current project). Or you can take a look at this: http://howardlewisship.com/tapestry-javaforge/tapestry-spring/ I don't know about it, but I would guess that this is the above approach put into a library.

Re: OGNL in javascript
Quoting Deon Visagie [EMAIL PROTECTED]:
I want to put an ognl expression in my onclick event of a link
e.g: onclick=ognl:'javascript: document.getElementById('userId').value=' +
user.Id
I'd say there is a syntax error with the single quotes, which occure
in the getElementById call. If escaping these does not work you can
try something like onclick=ognl:makeJavascript() and implement
String makeJavascript() in the coressponding class to return the
desired string.

Christian

Re: Invalidate session
Quoting Bryan Lewis [EMAIL PROTECTED]: This has been discussed a few times before. For example, Yes, I have googled a bit and found some small discussions. But they were not to helpful. As you say, Tapestry doesn't allow the exception to bubble up to the user, but it does put a worrisome stack trace in the log. The Tapestry developers weren't highly motivated to fix this minor annoyance :-) so Well, it is more than an annoyance when you deploy in Tomcat 5.5.15, where the exception reporter gets a null pointer exception from the session.getID(). The user will get a tomcat error report and not the logout page. I just ignored it for a while, and then worked around it in my custom Engine. It's not pretty but hey, it's a work-around. Thanks.
