Re: How to implement polling with @EventListener
Yay, it works, thanks. It really looks like there should be a more elegant
solution to this, but hey, it works.
Now I am facing a different thing, using AJAX requests I only want to
transfer deltas. For example if there are 11 rows on the screen and on the
next update there is a new one, I don't want to transfer 12 rows then, only
one and add it to the other rows.
Is there an elegant way? Or do I have to create component instances
dynamically?

The following is contrived, but works. Mainly, I would create a proper
dojo widget and have the event listener bind to that, but this works
because of expando properties...
In your body of a file called Test.html, I have
div id =test/div
script type=text/javascript
dojo.require('dojo.lang.*');
dojo.require('dojo.event.*')
var tst =dojo.byId('test');
tst.update=function()
{
dojo.debug ('running')
dojo.lang.setTimeout( tst.update , 4000) ;
// im sure ther animation package had
//a proper way of scheduling something for repeating, but...
};
dojo.addOnLoad(function(){
dojo.byId('test').update() ; // get the ball rolling
});
/script
div jwcid=[EMAIL PROTECTED]
span jwcid=@Insert value = ognl: now
the current time is
/span
/div
then in Test.java,
abstract public Date getNow() ;
abstract public void setNow(Date now) ;
@EventListener( elements =test, async = true ,
events =update)
public void update (IRequestCycle cycle )
{
setNow(new Date()) ;
cycle.getResponseBuilder().updateComponent(status);
}
and boom!
As you load hte page in javascript, test.update gets called which in
turn causes the server side event listener to run. The event listener
updates the clock (every 4 seconds because I was running this in devel
mode and, and I mean nothing, pisses tapestry off more than running in
devel mode) and the page reflects it without any refresh.
Hope this helps, sort of...

Hi,

How do I use that properly with Tapestry 4.1? The EventListener seems not

I want a component that reads a property from a server all 4 seconds. For

Re: Dynamic Link
Hi Nielsh, You can use a special renderer on DirectLink, PageLink, ExternalLink and so on..: bean name=popupRenderer class=org.apache.tapestry.contrib.link.PopupLinkRenderer set name=windowName value='disclaimer'/ set name=features value='width=300, height=500, scrollbars=yes, resizable=no'/ /bean On template: a href=# jwcid=@DirectLink page=ognl:page renderer=ognl:beans.popupRendererspan jwcid=@Insert value=ognl:linkTitleLink/span/a Don't forget to use the @Body component, becouse of the generated javascript See the documentation for more details about features and so on...

How to link from item list to item detail
I'm writing an application where logged in users can create items. User can then list their items and by following a link (DirectLink) they will reach the item details page where the selected item can be edited. This is a typical scenario which I imagine occurs in many apps. I have implemented the link with a DirectLink which has the item ID as parameter. In the listener I will create the page, set the ID on the page object and the return the page object. It works fine! The thing is that a user can reach other users items by editing the URL for the detail page - the URL ends with i.e. ...sp=3 where 3 is the item ID. This means I will have to check on the details page that the item to be shown is indeed owned by the current user. OK, I can do that, but is there maybe a better way to perform the link? /Malin
RE: How to pass a reference of ASO to my SqueezeAdaptor
Ohhh. . . .this is *so* close to what I need!
I have a stand-alone HttpSessionListener impl class in my Tap 4 project
that needs access to an ASO.
As a hivemodule noob, how can I get access to the
ApplicationStateManager like shown in Barry's awesome example below?
I *assume* I can't define my HttpSessionListener as a 'service point' or
'contribution' or 'purple elephant' or any other hivemodule glyph, which
is why I'm posting here.
Thanks in advance!

Re: Trace clients actions
I know one of the logging packages has a feature that allows you to bind logging output to a particular user associated with a particular servlet session. I'd probably go that route.

Re: external form submissions
Chapter 8 of the book Tapestry in Action discussed (also relevant to Tap4) a way of submitting an 'external' form to a Tapetsry page. (I think you can download the example source code of the book for free from Manning's web site.) Briefly, you set up a Tapestry page whose java class extends BasePage (as usual) and also implements the interface IExternalPage. http://tapestry.apache.org/tapestry4/tapestry/apidocs/index.html The interface IExternalPage has a method activateExternalPage(java.lang.Object[] parameters, IRequestCycle cycle) . You submit your form to the above Tapestry page and you retreive the submitted parameters from the form in the method activateExternalPage.

Re: Trace clients actions
Right... that's been working well for us. I have a request listener
method in a POJO:
import org.apache.log4j.MDC;
public class EventListener implements ServletRequestListener // among
others
{
public void requestInitialized(ServletRequestEvent sre) {
HttpServletRequest req = (HttpServletRequest)
sre.getServletRequest();
HttpSession session = req.getSession();
if (session != null) {
// Get the userName stored in session at login.
String userName = (String) session.getAttribute(USERNAME_KEY);
MDC.put(user, userName);
}
}
}
Then my log4j configuration has a ConversionPattern:
... (%X{user}) ...

Most of the time a checkbox - by definition - is more of a boolean operation than value...But far be it from me to argue with semantics that do work..
