Tacos : Disable Form component when request
Hi All, I would like to ask that is it possible we can disable the component in a form when ajax request and enable the component back after ajax response by using tacos? Can anybody provide me some guide in doing htis? Thank you! -- Regards, Khong Seng Kin
RE: Wiring up an Export service
Patrick,
I've just been tasked with integrating BIRT into our Tapestry 3 application.
It appears as if you've done most of the heavly lifting already.
Would you be willing to share a little more detail about your integration.
I can roughly follow what you've outlined below, but it appears as if all of
the BIRT magic takes place in your ReportManager class. Also, out of
curiousity, what are the issues you ran into with date parameters and BIRT?
Thank you for your time.

Subject: RE: Wiring up an Export service
Steve,
Probably the easiest way to invoke a service is to link directly to
it rather than use a directlink, have the page listener fire, and then
invoke the service. So what I'd recommend is that you see if you can use the
existing ServiceLink component to invoke your service or, alternately, just
write your own "PDFLink" component.
Here as a model is a service of mine that prints BIRT reports (I'm
not including all the dependencies but you an see the code flow). Also
attached is the ReportLink component that links to it.

Sorry that I wasnt clear about the problems that I've been met. I've tried to look into the code, when there is other Tapestry Form within the same page with Tacos AjaxForm, Tapestry.register_form doesnt get called which causing related issues like client side validation will not be handled.

RE: strange problem losing session variables
I've seen something like this once before involving an app designed for a small number of large sessions. My problem was that I was persisting my sessions in-memory. When there was no more memory available, my app server (weblogic 8.1) conveniently started discarding sessions. Turning on JDBC session persistence and making a bunch of classes implement Serializable fixed the problem. I expect disk-based persistence would also have worked fine. I'm not sure if this problem is specific to weblogic or applies to other app servers, though. -Steve -Original Message- From: John Menke [mailto:[EMAIL PROTECTED] Sent: Monday, June 05, 2006 10:04 AM To: Tapestry User Subject: strange problem losing session variables Is anyone experiencing any problems with "lost" session variables?

No. Its is up to Tapestry to fix it brokenness?
Webwork is not mentioned in spring's lib/src, yet its spring support is
superior.
Right now tapestry's spring support is kind of half baked. Pages cannot be
autowired from spring.
In addition, I don't think its possible today to do "prototype" proxy-ing of
Tapestry pages/actions via auto-proxy or explicitly, since spring cannot
create the abstract tapestry pages. We will have to wait for the framework
to become more pojo based.
For now, I believe recommendation "explicitly" inject your singleton
services. All the advice would be specified on the service.
If you don't want your services to be singletons, I am not sure if all that
lifecycle handling is complete yet.

Subject:Tapernate and Spring
Hi all,
In a recent different thread, the question about "Why use Tapernate if
you use Spring" had come up as a side-question.
It seems that some (Hibernate-related) features of Tapernate are
alternatives to equivalent Spring features, while others are more
Tapestry-related features (e.g. the DataSqueezer) that are not available
in Spring, since Spring does not have explicit Tapestry-support.
For some of the features listed on the feature-list at
http://www.carmanconsulting.com/tapernate/ I am not sure which category
they belong to:
- Is there anything in Spring that deals with the
reattachment-strategies ("Persistence Strategies" on the list)?
- Is the "POJO-Rollback" functionality covered by Spring's Transaction
facility?
Does anybody know if there is a document with a comparison of the
various frameworks/add-on libs that offer persistence-support
(Tapernate, Hivetranse, Honeycomb, [Spring]; are there more?) for
Tapestry? Like a quick features and pros/cons comparison?
Thanks,
MARK
P.S. James, did you forget to list the transaction-strategies on the
feature list, or did you leave it out intentionally?

RE: Hibernate persisted data never makes it to DB
+1 Don't use autocommit. You might wind up changed pojo's where you've changed a couple properties yet never called/save/update commit etc. Just specify transactional advice on your persistence manager. Shame there is no way to specify spring transactional advice on pages/actions like other frameworks can.

Re: Trails
Actually, my first trails (and tapestry) project was for a customer who had an existing database with lots of odd relationships in it, and which I managed to map one class at a time, by creating classes with the same name as the tables and pasting the description into a comment. I didn't have to make it complete but just did a couple of properties at a time by trial and horror, and the pages just popped up, existing data and all. It was a way-beyond-wow moment, to be sure.

Hi, I'm having some trouble with the tacos Refresh component.
I have a component that needs to refresh a list of images on occasion, so
I've inserted the following code in the component's html file.
function refreshImageList() {

The component is used in one of my pages. Once it's running, whenever I
click on any of the page's submit buttons (which are all AjaxSubmit), I get
this exception:
org.apache.hivemind.ApplicationRuntimeException
Component product/ProductEditPage/$data$ImageBrowser.$Refresh requires
rendering support, but no PageRenderSupport object has been stored into the
request cycle. This object is typically provided by a Body component. You
should add a Body component to your template.
However, I DO have a Body component on my page. Not only that, if I take
that javascript function and insert it directly into the page's html file
instead of the component's html, it works perfectly. I could leave the code
on the page but it wouldn't be a very clean solution.
Any ideas on why this is happening? I tried it with Tacos 4 beta 2 and with
the latest bleeding-edge tacos 4 beta-3-20060601-0613.

Re: getting rid of cycle.activate
That won't do, he's in 3.0.3...
Perhaps you can try the code described here:

It will save you a few keystrokes

What you're suggesting is only available as per Tapestry 4.0+
For tap 3.0.x listeners methods return void

RE: Tapernate Squeezer...
Actually, I like Adreas Androu's idea. He said (from the developers list): "I think I would use the entire entity name enhanced with an optional properties file that would allow users to define substitutions." However, I'm going to go one better. Instead of using a properties file, I'll create a configuration point for the overrides. That's the "HiveMind Way." When I said "use the hashCode()", I meant to use the hashCode() of the entity name (a String) itself, not of the entity. -Original Message- From: Andreas Bulling [mailto:[EMAIL PROTECTED] On Behalf Of Andreas Bulling Sent: Tuesday, June 06, 2006 8:24 AM To: Tapestry users Subject: Re: Tapernate Squeezer...

You have to escape the ('userId'), like this probably: (\'userId\')

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.

Tapernate Squeezer...
For those of you who are using Tapernate (and those of you who have done something similar in the past), I have a question for you.

getting rid of cycle.activate
Hi all,
I've been using Tapestry 3.03, and I need help getting rid of
cycle.activate, because it is messing up my URL structure.
When I want to direct a user to a page, I might use cycle.activate, for
instance when i've completed a login procedure or inside a direct link.
Its very convenient to write java code like
IPage mypage = cycle.getPage("mypage");
cycle.activate(mypage);
Trouble is, that the url for this page is now somthing like
/app?service=direct/1/Someotherpage/$DirectLink$0
so I might have many URLs that point to the one page. Perhaps I could
use RedirectException, but would I then have to write a lot of code to
get the engine, get the service, get the link and finally throw the URL?
seems a lot of work. Whats the best way of doing it?

Hivemind SpringLookupFactory
Hi all, I need to inject a Spring bean (wich is a DAO) in my Tapestry Visit session object. After some readings, the solution seems to be the declaration of a new ASO in Hivemind for the Visit object and the injection of my Spring bean in this new ASO using the Hivemind SpringLookupFactory. But, as a newbie in Hivemind, i did not success to make this configuration and did not find any sample on the web using SpringLookupFactory. So i send here my SOS ! Has anybody already used the SpringLookupFactory and could show me a configuration sample ? Thanks in advance. -- Stéphane Decleire 05 56 57 99 20 06 63 78 69 06
