Re: T5 BeanEditForm and selectObject component
I found out that the real cause of the problem was beaneditform add
parameter.
For example
t:beaneditform object=deposit add=account model=depositModel
t:parameter name=account
...
/t:parameter
/t:beaneditform
will fail and
t:beaneditform object=deposit model=depositModel
t:parameter name=account
...
/t:parameter
/t:beaneditform
public BeanModel getDepositModel() {
...
model.add(account);
return model;
}
will work.

Re: T5 GWT Integration
Thanks! I hope it's useful. The one thing that I haven't tried yet is getting the GWT hosted mode to work in the same project, since that's a really rapid way of seeing what you're doing. Also the way the GWT compiler has to output into the webapp source directory is a little flaky (you have to refresh eclipse, and maybe even delete the old gwt compiled js code if the hash is different). Maybe Maven Assembly could be used. I'm very happy with T5 being the parent web app, and just having GWT components. As much as the GWT hardliners want to believe it, multi-page web apps are not dead. :-) Daniel On Thu, Jan 15, 2009 at 4:34 AM, Peter Stavrinides p.stavrini...@albourne.com wrote: Thanks Daniel!!

Re: How to specify onUnload in body ?
You can observe browser events also by using prototype Event.observe
function. For instance you can use this javascript code in your page:
Event.observe(window, 'unload', function() {
// your unload actions
});
In this case you don't need direct access to html body element what will
simplify your situation.

Hi,
I have a template component that is used by all my pages. I'd like to be
able to specify body onUnload=... for one of those pages. Unfortunately
it doesn't seem to matter what way I try I cannot get it to work.
I can't include a body in the page because then there will be two such
tags (Firefox doesn't mind, but IE doesn't recognise the second body tag -
plus it is poor form anyway).
I can't include onUnload in the template body because it appears to just
be replaced with a standard body tag when the page is rendered.
I can't use any form of t:if ... (which I would have liked to do -
passing the onUnload string into my template and then choosing a single
body or parameterised version depending on whether the value was null)
because body has to match with /body and the /t:if tag obviously
screws this up.
I can't use t:outputRaw to generate my tag because it won't generate
special characters properly ( and ).
I don't recall having these sorts of problems with Tapestry 3 when I used
it many moons ago. It seems T5 is really rather limited in this respect.
Is there any way to do what I want? It is rather critical that I can
perform onUnload.
thanks,

Re: Connection Problem
Hi guys, just want to give an update. My problem has been solved, i've been leaving it for days and there's no connection problem. in my case, the problem was I'm missing this one line : property name=connection.provider_classorg.hibernate.connection.C3P0ConnectionProvider/property and the real c3p0-0.9.1.jar file.

Re: EJB questions about Jumpstart

I see there is a FAQ in Glassfish about this. If you have the WAR and

injecting the bean into the web class with @EJB. See https://glassfish.dev.java.net/javaee5/ejb/examples/Sless.html

Re: EJB questions about Jumpstart
Your lookup string looks fine according to the doco I've just read.
Have you confirmed the jndi entries exist and their format? See
http://www.myeclipseide.com/PNphpBB2-viewtopic-t-18850.html
Have you provided jndi properties to the InitialContext? This is
usually done by putting a jndi.properties in the classpath (Glassfish
server may already have one?) or specifying the properties
programmatically .
This FAQ may help: https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html
Beyond that I can't help without imitating your setup which I
unfortunately don't have time to do. Sorry if I have only covered
ground you have already covered.

Re: Tapestry With Connector
http://www.google.com/search?q=sql+server+jdbc What's wrong with you? The first two results link to two implementations for Microsoft's sql server. Just look them up in your maven repository of choice and add them to your pom. Same applies to other vendors. And if you don't know how to add dependencies to your pom or what the different tags mean and what to input where, look it up in the maven documentation. Uli Gutemberg A.

PersistentFieldStrategy and conversations
I'd like to implement a custom PersistentFieldStrategy for conversations within the same page, but a PersistentFieldStrategy only knows the page name. Currently my conversation id is part of the activation context and I'd somehow need to pass the id on to my custom strategy. Is there a way to do this? If I could obtain the page instance, the request or a filter I could probably work it out. Also, PersistentFieldStrategy only has discardChanges(String pageName) (and Page has discardPersistentFieldChanges() ) which discards all changes, but I'd need it to discard changes for specific conversations only. Should I perhaps open an enhancement request for it? Howard, care to comment? Kalle
volatile and persistence
Maybe somebody can help me out here.
I am trying to get my head around the implications of the persistence
and the combination with using volatile or not.
I have built a test page which contains a list of objects (for the sake
of the example, each one only contains a string. A form is displayed
with five items in it. You can change any of the items and commit. All
very simple (the source follows).
If I do this using a non volatile loop, the changes in the textfield
components are not persisted. When I make the loop volatile, they are.
I assume the persistence strategy has something to do with this, but I
don't see the textfield state being saved (actually I also tried using
the client persistence stratgey, but this just crashed the application).
It seems that when volatile is true, the objects from the list are
unserialized from the form data, which makes them different from the
objects in the page (which is just plain persisted), causing problems.
Can somebody shed some more light on this? If my assumption above is
true, then the documentation for loop and grid need a lot more
explanations when volatile should be either true or false.
Thanks,
Joachim

Re: PersistentFieldStrategy and conversations
Yeap, working on it, just figured it should be safe to use the shadow. With the current interface, discarding changes (of conversations) might yield unexpected results though; I'll see what becomes out of it once I get a little further along with the implementation.

Also, PersistentFieldStrategy only has discardChanges(String pageName) (and Page has discardPersistentFieldChanges() ) which discards all changes, but I'd need it to discard changes for specific conversations only. Should I perhaps open an enhancement request for it? Howard, care to comment?

T5 and hibernate slowing with more records
Hello,
I am using POI to take an excel file and put it into a Mysql database using
hibernate.
I put a counter on the records going into the database and it starts off
fast but then slows to over 15 seconds a record and I cannot figure out why.
My code is basically this:
Public class DatabaseDump{
@Inject
Private Session _session;
Public void onAction(){ //they hit the go button
Loop rows{
_session.beginTransaction();
Loop cells{
Fill the
object from the cells
_session.save(Object);
}
_session.getTransaction().commit();
}
}
Everything works fine as in the database gets filled for the rows it has
completed but gradually slows to a crawl and at around 2700 records of 10500
records it's a record every 15 seconds.
I run the project under eclipse using Tomcat. The memory starts at around
80mb and only goes up to around 110mb.
What am I doing wrong?

Blog post - Customizing Eclipse for Tapestry 5 template editing
Hi guys, if any newbie lurks around here on the mailing list, I made a new blog post with screencast at http://bbwebcraft.blogspot.com/. This time it is about how to tweak your development environment to speed up editing Tapestry's template files. For others, if you have any suggestions, please leave a comment. Cheers, Borut
Forms
Guys, Im trying to make a small search engine, but It isn't working.follows
the code:

Java:
public class Start
{
@Component(id = names)
private Form _form;
private Long cdCliente = new Long(7);
@Property
private String dsQuery;
@Component(id = dsQuery)
private TextField dsQueryField;
void onValidateForm() {
if (dsQuery == null || dsQuery.trim().equals()) {
_form.recordError(dsQueryField, First Name is required.);
}
}
Object onSuccess() {
//new Exception(E... + dsQuery).printStackTrace();
return this;
}
}
It had no onSuccess, but didn't worked either.
Im using the same Start.java as response to the form.

problems when using FormFragment in a loop
After two days of hunting, I have discovered a bug (or maybe better) limitation. If you try to use the FormFragment component inside a loop, then the updates caused by the form elements in the formfragment will only be applied to the last item in the loop. The form elements seem to be included at the end of the form instead of inside the loop element, which causes the problem. Maybe at a minimum the documentation could be modified to indicate this limitation.

Re: [T5] improve documentation
Completely agree with the sentiments expressed. Too often I've had to use Google or similar to find what I'm looking for in the Tapestry documentation. Having it split across at least 4 different places and in some places confused with Tapestry4 is awkward. Szemere
Re: T5 and hibernate slowing with more records
Feels like a Hibernate question, not Tapestry. Does your table have the right index, do you need to have 10k transactions in a single web-request? Szemere

Re: T5: Reading context before persistent fields are read
Hey Ted, I happened to run into the same exact problem you were having while trying to get my custom conversational PersistentFieldStrategy implemented. Did you manage the solve the problem (reading values from activation context before gathering persistent fields) in any satisfactory way? Kalle On Fri, Jan 18, 2008 at 4:59 AM, Ted Steen ted.st...@gmail.com wrote: Hmm, i must have been very tired when i tested this yesterday. It doesnt work. The ComponentActionRequestFilter is handled after the persistent fields are gathered. So my activation context variable that I need when gathering persistent fields is not set before I gather the fields. I have tried to add the filter with before:* A solution would be to inject the Request into the PersistentFieldStrategy and get/decode the context from the path (or post variables when posting) .. but that is not very clean in my opinion. It would be nice if the gathering of fields was done a little later or maybe we could extend the Request API with a Object[] getActivationContext() Or do you have any other ideas. I feel I should explain my use case here.. We are developing a checkout service where the current cart beeing processed is passed around via a activation context variable (the cart-hash). This means that the persistent variables in the components should be per cart-hash. This can be done transparently by implementing a custom PersistentFieldStrategy which uses the first value in the activation context (we decided that the cart-hash should always be the first value). Or the hash could be a part of the domain like hash.mydomain.com, then the session is made unique per host and everything will work like expected. this is a third solution 2008/1/18, Howard Lewis Ship hls...@gmail.com: The pipelines and chains of command make it easy to slip in specific logic.

Thanks! 2008/1/18, Howard Lewis Ship hls...@gmail.com: If you mean the event context (as opposed to the page activation context), then ... The path of least resistance is: 1) Define a service with a simple read/write property to store the context. Make sure this is perthread scope. 2) Contribute a filter to the ComponentActionRequestHandler pipeline. The filter can capture the event context and store it in your service. 3) In your PersistentFieldStrategy, inject the context-storing service and read the context. You might simplify #1 to just store the piece of data you need from the context. The approach is similar if you need page activation context, but you'll need to contribute a similar filter into the PageRenderRequestHandler pipeline as well.

Re: profiling tapestry components
Well, we have a large app that is not performing very well.. and now I have to figure out how to make it more performant.. And I was just wondering if dumping component level response times, could maybe give me some sort of clue as to what to focus on.. It's a slightly different view of the code and work being done, instead of at method response times.. because there is no one method for rendering a component or page, etc.. so, just a thought. I guess I can tweek ComponentPageElementImpl to add extra RenderingEvents to do this.. interesting..

RE: T5 and hibernate slowing with more records
Hello, I suppose I could restrict the number of records allowed however I do not believe that I need to. I believe there is a problem somewhere, maybe in how I am doing the transactions or something. Before using t5/hibernate we were using t3/torque and if that system would have no problem with this I cannot see the newer technology having any problem. I guess I will ask the hibernate forums but I thought it would have something to do with the way I use the session/transactions. --James -Original Message- From: Szemere Szemere [mailto:szemereszem...@googlemail.com] Sent: January-15-09 6:30 PM To: Tapestry users Subject: Re: T5 and hibernate slowing with more records Feels like a Hibernate question, not Tapestry.

Re: T5 and hibernate slowing with more records
Hi James,
I do not see any reason why it is slow, but would suggest to do following:
1) try to put everything into a list of objects without saving to the
database, slow?
2) use a service to accept the list from #1, beging a transaction, save,
commit, slow?

Re: T5 and hibernate slowing with more records
Can you avoid committing the transaction on every item? Committing
takes more database effort than the initial update/insert, so batching
these within one transaction is highly advisable if it's possible.

a quick way is:
instead of creating a service, make something like this
@CommitAfter
private void saveThem(ListMyobjt lst) {
// put code here to save objects, don't beging a transaction as it has been
started by Tapestry-Hibernate
}
how long?

By the way, nice performance improvement hunting! :) Don't forget to share your experience with us. ;) -- Thiago H. de Paula Figueiredo Independent Java consultant, developer, and instructor http://www.arsmachina.com.br/thiago - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
