T5 Reference page attributes from a component
In our T4 app we made a lot of use of this type of construct: This particular component is embedded 4 layers deep and was able to reach back all the way to Page class to get values. Is there a similar construct in T5 or am I going to have to pass these values explicitly down the components?

onPrepare(Integer id)
I'm trying to create a simple form that will work for both Add and Edit. I'm
trying to use onPrepare to setup the database object and the code works fine
for an existing object. When I try to use the form with a new object (id =
null) it appears that onPrepare isn't called, so I end up with null pointer
exceptions trying to build the form.
Here is my simple controller:
package com.starpoint.helpdesk.pages.office;
import com.starpoint.helpdesk.business.OfficeLogic;
import com.starpoint.helpdesk.domain.Office;
import com.sun.istack.internal.Nullable;
import org.apache.tapestry5.annotations.Log;
import org.apache.tapestry5.annotations.Persist;
import org.apache.tapestry5.annotations.Property;
import org.apache.tapestry5.ioc.annotations.Inject;
import org.slf4j.Logger;
/**
*/
public class EditOffice {
@Inject
private Logger logger;
@Inject
private OfficeLogic officeLogic;
@Persist
private Integer officeId;
@Property
private Office office;
public Integer getOfficeId() {
return officeId;
}
@Log
public void setOfficeId(@Nullable Integer officeId) {
this.officeId = officeId;
}
@Log
void onPrepare(Integer officeId) {
if (office == null) {
office = officeId == null ? new Office() :
officeLogic.getOffice(officeId);
}
}
void onActivate(Integer officeId) {
this.officeId = officeId;
}
Integer onPassivate() {
return officeId;
}
public Object onSuccess() {
logger.info("**: " + office.toString());
return this;
}
}
And my form:
http://tapestry.apache.org/schema/tapestry_5_1_0.xsd";
xmlns:p="tapestry:parameter">
Office Name
Save
Office
What am I missing?

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 {
List getAllOffices();
}
The page was of course updated to call this method instead of the DAO directly.
The updated applicationContext.xml is:
http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:context="http://www.springframework.org/schema/context";

So maybe I should have sent this question to the Spring list?
All the same, does anyone have any insight into what I may have done wrong?

Tapestry Hibernate Sessions
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 List 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?
I have Spring configured like this:

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:
consoleEnabled="ognl:true">
Test:
You picked format="ognl:format.numericDate" />
Current Number:
And my controller
package com.starpoint.instihire.web.tapestry.page;
import org.apache.log4j.Logger;
import org.apache.tapestry.annotations.Component;

public abstract Date getTheDate();
public abstract void setTheDate(final Date theDate);
@InitialValue("0")
public abstract int getNumber();
public abstract void setNumber(int n);
public void submit()
{
}
public boolean getShowTheDate()
{
setNumber(getNumber() + 1);
return getTheDate() != null;
}
}
I hope this helpful.
As always, thanks again

Hi,

The problem is that I have an IF component that is being called 3

I have extracted the problem into a simpler page for examination:

Hi
Output to console:

Output to browser:

Note that I've stripped the code down. There is no way for the user
to exist in this example, I'm simply reloading the page when the
server starts. (Tomcat 5.5.23) This code was part of my Home.page,
which decides whether or not to display a login component or greet the
user.
How can I get it to only check the IF component once? (or better yet,
why is it called three times?)

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.

I'm assuming that any value between 1 and 99 should work. I just tried 1234 and it failed as does every other number I type in.

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

Sorry for the inconvenience, you caught me in the middle of some larger
changes and I guess this use case was a victim.

Re: Tap 4.1.2 EventListener
A little additional info.. when I change the value on any of the inputs
beyond the first one, it is causing the form to be submitted, it just
doesn't call my EventListener method. Also, I am using the latest
(today's) Tapestry build.
Thanks again

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:
value="ognl:jobExportValues.externalJobBoard" />
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?

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:
value="ognl:jobExportValues.externalJobBoard" />
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.

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: to my Tapestry.application and was able to get the behavior I was after. In short, consistency wins in my book every time. Tony Nelson - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
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.
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.

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]
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

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.

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.
