Hi all,
I'm in the process of rebuilding an app that was done in Tap3 (indeed!) in
Tap5. It's a small app, maybe a dozen pages used by my internal staff. This
is in preparation for rebuilding the entire front of a much larger app. But
that's a story for another day.
Because I want to learn all the new Tap5 goodness, I started with an new
project built w/ the maven archetype. I copied over my DB classes and added
the Spring dependencies I needed, and wrote a test case to make sure I could
read and write from my dev (h2) database.
Then I created a very small page that displays a few rows from the DB in a
table. The service method is trivial:
@Log
public ListOffice getOffices() {
return officeDao.getAllOffices();
}
I fired up Jetty, and opened the page. I really expected to get an exception
saying that I don't have a database session because I purposely did not
include the OpenSessionInView filter that I'm familiar with. In addition I
didn't include the tapestry-hibernate jars because I'm not sure if it's
better to have Tap of Spring handle opening and closing the sessions.
I was very surprised when the page actually rendered a result from the
database. I'm still not clear where the session is coming from, but that is
actually my problem. I can reload my tiny test page 8 times. On the 9th
time, I see:
[582385532@qtp-918884489-5] DEBUG com.starpoint.helpdesk.pages.Offices -
[ENTER] getOffices()
And the browser spins. I can open the H2 DB in the H2 admin console and
issue queries against it, so the H2 instance is fine.
Obviously I'm either out of sessions or connection pool slots. My goal is to
be able to use the Spring @Transactional annotation because in the larger app
rewrite I have several dozen business layer Spring managed beans that depend
on it.
I have tried adding Springs OpenSessionInViewFilter, and I've tried adding a
dependency on tapestry-hibernate-core. Neither of these solutions have
helped.
Can anyone offer any suggestions as to where the session is actually coming
from so that I can try to figure out how to get the session closed or
released?

Indeed it was a Spring related issue. Doing some more searching I found that
Spring requires @Transactional now, and I had only added my data access tier.
Creating a quick business tier and marking the interface @Transactional solved
the problem. For anyone that may find this in [insert favorite search engine]
later:
My interface for my business class:
package com.starpoint.helpdesk.business;
import com.starpoint.helpdesk.domain.Office;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
@Transactional(readOnly = true)
public interface OfficeLogic {
ListOffice getAllOffices();

The page was of course updated to call this method instead of the DAO directly.

Re: Hopefully an easy one
No, it will accept user input as: 5/17/07 which gets translated in my queries to 5/17/0007 and causes hibernate to self destruct. If a user enters 5/17/07 I expect an error to be raise, but alas, no.

Re: [Tap 4.1.2] Problem with repeated calls to an If component
I have noticed similar things happening in my code on the 4.1.2 snapshot
as well.
Trying to debug the issue I'm having w/ DatePicker (different thread) I
added a conditional to the page, and used your strategy of counting @If
calls just to see what I get.
The first time I load the page, on the very first display, my page shows
that the conditional was called 4 times. Every time I submit the form,
and it redisplays, the conditional is called only one time. I am
actually very hopeful that the solution to this problem, will also yield
a solution to other problems I am seeing that are very hard to replicate
that involve nested components throwing OGNL null pointer exceptions
when I know for a fact that the data should exist.
For completeness, my template:
span jwcid=@Border title=Test showMenu=ognl:true
consoleEnabled=ognl:true
form jwcid=@IHForm clientValidationEnabled=ognl:true
labelTest: /label
input jwcid=[EMAIL PROTECTED] value=ognl:theDate
translator=translator:date,pattern=M/d/
validators=validators:required
displayName=As of Date/
pspan jwcid=@SubmitButton listener=listener:submit //p
/form
span jwcid=@If condition=ognl:showTheDate
You picked span jwcid=@Insert value=ognl:theDate
format=ognl:format.numericDate /
/span
br/
Current Number: span jwcid=@Insert value=ognl:number /
span id=debug
/span
/span
And my controller
package com.starpoint.instihire.web.tapestry.page;

import org.apache.tapestry.annotations.Component;
import org.apache.tapestry.annotations.EventListener;
import org.apache.tapestry.annotations.Meta;

public abstract Date getTheDate();

Tap 4.1.2 EventListener
Is it possible to use an EventListener in a component that is displayed
multiple times on a page?
Specifically, I would like a component that has 2 inputs, and when the
1st one is updated an onchange event causes the 2nd component to update
it's value. From my testing, it appears that only the first component
responds to a change event (meaning causes my java method to be called),
and when it's called, I don't seem to have access to the updated values.
My component in progress looks like:
input jwcid=[EMAIL PROTECTED] value=ognl:jobExportValues.id /
input jwcid=[EMAIL PROTECTED]
value=ognl:jobExportValues.externalJobBoard /
input jwcid=jobIdField value=ognl:jobExportValues.jobId size=5 /
And I register the EventListener in the component as follows:
@EventListener(events={onchange}, targets=jobIdField)
public void testEvent()
{
logger.debug(LOOKHERE... + getJobExportValues().getJobId() +
+ getJobExportValues().getId());
}
When the listener is actually called, I always get NULL for both
values. And again, the listener only fires for the first component on
the page.
Looking at the page source, it appears that dojo code for all of my
inputs is being generated which I won't include here due to it's length.
Any help would be greatly appreciated. Am I just missing the whole
concept on the new dojo stuff?

doesn't call my EventListener method. Also, I am using the latest

Re: Tap 4.1.2 EventListener
I grabbed the latest snapshot and now the callback is getting called for
all of my inputs. Thank you very much.
I still get NULL as the value, but I think that's my fault. I'm going
to have to do some serious thinking about how this page works.
For my understanding, when the onchange event fires, what data should
I expect to be posted back to the server? The entire form? Or just the
changed field? Reading all the logging that I have in my page, it
appears as though the entire page is being reconstructed (like a
rewind?) on the back end. Is that normal? Should I expect that?
I'm going to have to add even more logging, but should I expect
pageBeginRender() to be called? I would expect not.. but I might be wrong.
I can see that Tapestry is definitely evaluating the entire template
because of all the logging I get just updating one field in the browser,
and I guess that might be necessary, I just need to figure out what the
consequences of that will be on my code.
Thanks for all your help

component responds to a change event (meaning causes my java
method to
be called), and when it's called, I don't seem to have access to the
updated values.
My component in progress looks like:
input jwcid=[EMAIL PROTECTED] value=ognl:jobExportValues.id /
input jwcid=[EMAIL PROTECTED]
value=ognl:jobExportValues.externalJobBoard /
input jwcid=jobIdField value=ognl:jobExportValues.jobId
size=5
/
And I register the EventListener in the component as follows:
@EventListener(events={onchange}, targets=jobIdField)
public void testEvent()
{
logger.debug(LOOKHERE... +
getJobExportValues().getJobId() +
+ getJobExportValues().getId());
}
When the listener is actually called, I always get NULL for both
values. And again, the listener only fires for the first
component on
the page.
Looking at the page source, it appears that dojo code for all of my
inputs is being generated which I won't include here due to it's
length.
Any help would be greatly appreciated. Am I just missing the whole
concept on the new dojo stuff?

Re: [vote] remove renderTags default of true for @If/@Else? (tapestry 4.1.2 )
I personally don't care which way you default, but I do think that all tags should have the same default. It's much easier to remember to turn it on/off if I don't have to try and remember which tags have which default. I added: meta key=org.apache.tapestry.renderTags value=true / to my Tapestry.application and was able to get the behavior I was after. In short, consistency wins in my book every time.

Tap 4.1.2 translators/validators
If a TextField has both a translator and validators defined, is the
input passed from the validators the output of the translators?
I have been trying to get something like this working in 4.1.2 (todays
snapshot) that worked fine in 4.0.
input jwcid=@TextField value=ognl:percent
validators=validators:required,min=1,max=100
translator=translator:percentTranslator
displayname=Percent Input/
My percentTranslator is registering the dojo events necessary to call:
translatePercentage:function(value) {
dojo.log.warn(enter translatePercentage);
if(!value){return 0;}
var result = parseFloat(value.replace(/%/,''));
dojo.log.warn(result= + result);
return result;
}
which simply strips any '%' signs out of the input value and returns a
Float (which is probably unnecessary).
When I submit my test form, I do see the log messages in Firebug as
expected, and it definitely is returning the value without a % however I
get a dojo validation popup that states the value is non-number, and
does not meet the min/max criteria.
Is there any way to find out what value is being passed to min/max?
Thanks in advance for any help.

Tap 4.1.1 TextField Ajax question
I am attempting to use @EventListener to submit the value of a TextField
onChange. So, I have an input defined:
input jwcid=myField value=ognl:text
displayName=Text /
In the page class I have:
@Component(bindings = {validators=validators:required})
public abstract TextField getMyField();
@EventListener(events={onchange}, elements=myField)
public void testEvent(IRequestCycle cycle)
{
logger.debug(LOOKHERE... + getText());
}
But I'll be darned if any of the events are firing.
To rule out other problems, I copied the big brother is watching
sample from:
http://tapestry.apache.org/tapestry4.1/ajax/eventlistener.html
to the same page, and it works just fine..

com.starpoint.instihire.web.tapestry.page.Test - User clicked on x/y

Am I barking up the wrong tree? My final goal is to have a dropdown
update it's contents based on the text in the TextField, but until I can
dynamically get it's value I'm stuck.
Thanks in advance for all the help.

Re: Tap 4.1.1 TextField Ajax question
I would be very happy to use Tapestry 4.1.2 but I run into a problem
every time I try the latest snapshot:
java.lang.NoClassDefFoundError: ognl/enhance/ExpressionAccessor
I assume this related to the OGNL stability you mention.
Is there a newer beta of OGNL I grab from somewhere to get moving along? If so
I'll just throw it in my local repository for now.
Thanks again
Tony

You want to use targets= . Elements = is strictly for pure html
elements and not tapestry components.
If you use the 4.1.2-SNAPSHOT version it will also automatically
figure out
which form your targeted components are attached to and submit that as
part
of the event so that you can do things like get the current value of the
field.
4.1.2 should be released very soon, just holding out for ognl stability.

4.1.2 Translator/Validation
It would seem to me that translators would be called before validators, but I'm not sure how that applies with the new dojo validation. Can someone suggest a place to find a sample? I have a requirement for my project that all inputs that are percentages before formatted with a percent sign at the end of the value in the input box which is easily accomplished with a translator. However if I apply a min or max validator, on submit I get errors because the form doesn't seem to call my translator to get the original value. Have I been staring at this too long? Does what I wrote even make sense? Thanks in advance (again) Tony Nelson - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Suggested version
Over the last year, we have slowly been converting an internal application from a home brewed infrastructure to Tapestry 4.0. Some of the new functionality we need to add would best be handled with Ajax and I so I started looking at the newer versions of Tapestry. I can't seem to figure out which version of Tapestry I should upgrade to. The official distribution page lists Tapestry 4.0.2 as the latest stable build. This version doesn't support Ajax to the best of my knowledge. Folks using Maven2 seem to be encouraged to use the 4.1.2-SNAPSHOT. Is it stable enough to be used in a production environment? Is it really a good idea? Is there an official distribution of 4.1.0 or 4.1.1 I should consider? Reading the e-mail list, I see a lot of people using Tapestry 5.0.3. Is there enough functionality ready for me to consider it? I assume this will be the longest migration path for us, but since I need to upgrade, if now is the time, so be it.
