Re: T5.2 Need Advice on JDBC and Transaction Mgmt

[Yohan Yudanara]

I've try it and it's working. Thank you very much.
Now I can use JdbcTemplate and declarative transaction on my Tapestry
Service, so I can take advantage of T 5.2 service reload feature.
This is improving productivity a lot.

Thanks...

Best regards,
Yohan Yudanara

  No, that's not really true. You could use the advise out of my first post
 on
  this thread and apply that to all your Tapestry services accessing the
  database. You could do this by searching for an annotation - you can even
  use the Spring @Transacational annotation but it's probably better to
 have
  your own (since semantics won't be completely the same).
 
  Here's how the advisor could look like (see other post for
  TransactionalAdvise).
 
  public interface TransactionAdvisor
  {
 void addTransactionAdvice(MethodAdviceReceiver receiver);
  }
 
  public class TransactionAdvisorImpl implements TransactionAdvisor
  {
 private final PlatformTransactionManager manager; // this is the
 Spring
  transaction manager
 
 private final MapPropagation, MethodAdvice transactionalAdvises;
 
 public TransactionAdvisorImpl (PlatformTransactionManager manager)
 {
 this.manager = manager;
 
 transactionalAdvises = new HashMapPropagation, MethodAdvice();
 for (Propagation propagation : Propagation.values())
 {
 transactionalAdvises.put(propagation, new
  TransactionalAdvise(manager, propagation.value()));
 }
 }
 
 public void addTransactionAdvice(MethodAdviceReceiver receiver)
 {
 for (Method m : receiver.getInterface().getMethods())
 {
 Transactional txAnnotation =
  m.getAnnotation(Transactional.class);
 
 if (txAnnotation != null)
 {
 receiver.adviseMethod(m,
  transactionalAdvises.get(txAnnotation.propagation()));
 }
 }
 }
  }
 
  In your module you have to bind the services and advise your DAOs:
 @Match(*DAO)
 public static void adviseTransactions(TransactionAdvisor advisor,
  MethodAdviceReceiver receiver)
 {
 advisor.addTransactionAdvice(receiver);
 }
 
  This advice method is configured to match against any service whose id
 ends
  with DAO, such as PersonDAO.

Re: Building a multizone update in a loop

See how it returns a new instance of the update when you call add?

You can change your code like this and it should get things working:

MultiZoneUpdate update =  MultiZoneUpdate(totalPriceZone,totalPriceZone)
for(Item item : getItems) {
  update = update.add(itemZone- +item.getId(), itemZone);
}
return update;

There are some recent defects filed to get this interface fixed,
hopefully someone will get some time to look at it for the 5.3

I have a zone that is rendered in a loop.  It has a text field that

that row's total and the total at the bottom of the page.

My code looked something like:

That works fine.

Now the requirements changed and I need to update the total on rows
other than the row that was changed.  My first through was something
like this:
MultiZoneUpdate update =  MultiZoneUpdate(totalPriceZone,totalPriceZone)

return update;

But that doesn't work.  It only updates the totalPriceZone.  So I
tried going back to what I had before, but this time creating the
Update on one line and then adding the itemZone on the next like this:

MultiZoneUpdate update =  MultiZoneUpdate(totalPriceZone,totalPriceZone)
update.add(itemZone- +item.getId(), itemZone);
return update;

I expected the code above to have the same result as my original code,
but it doesn't.  It only updates the totalPriceZone.

Should I expect the first piece of code and the last to do the same
thing or is there some reason that you can't call add on the
MultiZoneUpdate after it is constructed?

Any other suggestions on how to create a multizone update when the
number of zones to add vary at runtime?

Tapestry5 and pop-up parameters

Re: Tapestry5 + Tomcat5 + Apache2

[LLTYK]

I think apache just isn't expecting urls to be in the js and isn't replacing
it. I wonder if Chenillekit should be using toAbsoluteURI, wouldn't a
relative path work just fine? 

As for the solution, well make your own copy of the mixin and fix it (I'd
make it use a relative path instead).

Re: chenillekit-tapestry 1.3.0 Unable to resolve 'chenillekit/TabSet'

[Borut Bolčina]

Just not to leave this hanging...

The problem has nothing to do with ChenilleKit nor with Tapestry - it is
Jetty related. I run the application in the command line (mvn jetty:run) in
Friday and forgot about it. Then I ran another instance within Eclipse, but
the browser was still responding to the first instance.

Can Jetty (or Jetty maven plugin) be configured not to start if the port

How to hide a component ?

Re: Tapestry5 and pop-up parameters

[Josh Canfield]

There isn't much information in your request so I'm not going to write
a book guessing every possible thing you might be talking about.

If you know the parameters that you want to pass when you are
rendering the page that opens the popup then you can use something
like:
@Inject
PageRenderLinkSource linkSource;

public String getPopupLink() {
  return linkSource.createPageRenderLinkWithContext(pagename, param1,
param2); // to create the link
}

script
window.open('${popuplink}');
/script

I haven't compiled/run this code so please forgive typos etc.

hi taha,

you could add the DiscardBody mixin:

or write your own one that implements some more sophisticated 
visibility-function.

Re: chenillekit-tapestry 1.3.0 Unable to resolve 'chenillekit/TabSet'

I'd be stunned and surprised if your second instance was able to start
on the same port. Try to do this intentionally and you should get a
port already in use error on the second instance, is it possible you
didn't notice the error? This isn't a Jetty thing, it's an OS thing,
or more specifically TCP stack thing.

If it's just hiding, use CSS for that. If you don't want the component to  
be rendered at all, there's two scenarios:


* Component which you can change its code: make it return false on  
@BeginRender. This could be made into a mixin.
* Component which you cannot change its code: no way to do it unless you  
write a mixin.

Tapestry 4.1 injecting the wrong application state object

[Pepijn Schmitz]

Hi everyone,

I'm having a bizarre problem with Tapestry, and I'm hoping someone here 
might be able to point me to a solution. Before I go into detail I'd 
like to describe the problem generally, in the hopes that it might be a 
known problem or someone may have encountered something similar.


The problem is that Tapestry 4.1.6 sometimes injects the wrong 
application state object on my pages! As you can imagine, this plays 
havoc with my application, with users seeing other users' details, or 
even worse, changing other users' information! It's a support and 
security nightmare.


I'm using Tapestry 4.1.6, and I'm using annotations instead of XML 
files. My pages all descend from a base class:


public abstract SupplierDNAPage extends BasePage {
@InjectState
public abstract SupplierDnaSession getSupplierDnaSession();

@InjectStateFlag
public abstract boolean getSupplierDnaSessionExists();

...
}

hivemodule.xml contains the following:

?xml version=1.0 encoding=UTF-8?
module id=com.supplierdna version=0.0.0
contribution configuration-id=tapestry.state.ApplicationObjects
state-object name=supplier-dna-session scope=session
create-instance class=com.supplierdna.logic.SupplierDnaSession/
/state-object
/contribution
  ...
/module

SupplierDNA is the name of the company I'm writing this for. As I 
understand it, this is the correct way of using application state 
objects. And most of the time, it works perfectly. When testing locally 
I have no problems with wrong application state being injected, and our 
demo system also doesn't have the problem.


The problems seem to start when the server is heavily loaded. Then, 
sometimes, getSupplierDnaSession() will return an application state 
object from a different session!!!


I have verified this by adding a pageBeginRender() listener method to 
the base class, and a client address property to the session. The 
listener method checks whether the client address stored on the session 
it gets from Tapestry is the same as the client address from the current 
request, and throws an exception if this is not the case. On our 
production server, this happens dozens of times a day!


The method also directly retrieves the application state object from the 
HttpSession and compares it to the one it got from Tapestry, and it 
turns out that the application state object on the HttpSession is the 
correct one, but somehow Tapestry is injecting a different one! This 
seems to rule out the web container as being the culprit (which is 
Glassfish 2 update 2, in this case).


Obviously this is a complex problem with a potentially huge number of 
contributing factors, but first I'd just like to know whether this 
sounds familiar to anyone? Is there a known problem with Tapestry which 
could cause this? Has anyone ever experienced something similar? Many 
thanks in advance for any help you can give me!


Kind regards,
Pepijn Schmitz

Context of a Zone

[Mark]

I have a form with a loop that looks something like this:

|__QTY__|_ITEM__|__PRICE__|
|__1_|_soup__|$1|
|__3_|_peas__|$3|
etc.

Users can change the quantity and it automatically changes the price.
Each price is in its own zone and the KeyUp action on the
cooresponding QTY causes that price zone to update. (I'm using the
zoneUpdater described at
http://tinybits.blogspot.com/2010/03/new-and-better-zoneupdater.html)

Now the requirements have changed and we need to be able to offer a
discount based on the number of items being purchased.  This means
that an update to the soup row will sometimes need to change not only
the price soup row, but also the peas row. At first I tried building a
MultiZoneUpdate (Thank you for your help Josh), but that just sets
every price to the same thing as the row that is being updated. This
is because the context of the row/event that triggered the updated
doesn't provide the context for the zones that need to be updated. If
I change the Qty of soup to 2, the soup item is the context for that
update, so when I update the row for peas, that zone doesn't know
anything about peas--only soup.

So my question is:
How can I access an item from the context when the zone was rendered
instead of the context of the section that is triggering the zone
update.

It seems like I could solve this if each zone was rendered with a
context that could be used when an update was triggered on that zone.
Something like:
t:zone t:context=item t:id=priceZone id=priceZoneId
${itemSubtotal}/t:zone

The idea being, that when you update a zone, it can figure out the
context at which the zone was originally created and not just the
context of the event firing the update. (Of course I don't know how
this would work on the Java side of things.)

Is there a way to do something like this?  Is there a different way to
do it that I've just overlooked and I'm making things harder than they
need to be?

Re: Tapestry 4.1 injecting the wrong application state object

[Koka Kiknadze]

I did have exactly similar problem couple of years ago - JSF app worked fine
from intranet, but messed up user sessions when accessed from WAN side.

So initial suspect was the squid proxy configuration of our ISP. The problem
disappeared as soon as we turned encryption on for the whole site (so that
proxy could not mess things up). Well, as the performance was acceptable
even with HTTPS we just left everything as is.

Hence I'd suggest temporarily requiring HTTPS for the whole site and if the
problem disappears, you'll know for sure it's not your application or
tapestry to be blamed.

Good luck.

 The recent documentation effort has been amazing. If you can't write

 the issues that will help the most people. Picking what to work on

 that you care about, they will get more attention. Add comments to
 defects that give helpful information about how you are experiencing

 if it's different from the submitter. The less time any of the
 committers have to spend figuring out what the defect means or how to
 reproduce the more time can be spent making appropriate changes :)
 
 Anyway, here's to continuing to build out a solid framework that best

 I'd be stunned and surprised if your second instance was able to start

Re: Context of a Zone

[Josh Canfield]

 but that just sets
 every price to the same thing as the row that is being updated. This
 is because the context of the row/event that triggered the updated
 doesn't provide the context for the zones that need to be updated.

Ah... static structure ;)

You have a single zone component and when doing a multi-zone update
you want to simulate a loop to get different content rendered for that
zone. I'm not sure there is a way to do this easily. It's definitely a
reasonable use case.

If your change is modifying all the prices, could you just re-draw the
whole table with an outer zone?

 I have a form with a loop that looks something like this:

 |__QTY__|_ITEM__|__PRICE__|
 |__1_|_soup__|$1|
 |__3_|_peas__|$3|
 etc.

 Users can change the quantity and it automatically changes the price.
 Each price is in its own zone and the KeyUp action on the
 cooresponding QTY causes that price zone to update. (I'm using the
 zoneUpdater described at
 http://tinybits.blogspot.com/2010/03/new-and-better-zoneupdater.html)

 Now the requirements have changed and we need to be able to offer a
 discount based on the number of items being purchased.  This means
 that an update to the soup row will sometimes need to change not only
 the price soup row, but also the peas row. At first I tried building a
 MultiZoneUpdate (Thank you for your help Josh), but that just sets
 every price to the same thing as the row that is being updated. This
 is because the context of the row/event that triggered the updated
 doesn't provide the context for the zones that need to be updated. If
 I change the Qty of soup to 2, the soup item is the context for that
 update, so when I update the row for peas, that zone doesn't know
 anything about peas--only soup.

 So my question is:
 How can I access an item from the context when the zone was rendered
 instead of the context of the section that is triggering the zone
 update.

 It seems like I could solve this if each zone was rendered with a
 context that could be used when an update was triggered on that zone.
 Something like:
 t:zone t:context=item t:id=priceZone id=priceZoneId
 ${itemSubtotal}/t:zone

 The idea being, that when you update a zone, it can figure out the
 context at which the zone was originally created and not just the
 context of the event firing the update. (Of course I don't know how
 this would work on the Java side of things.)

 Is there a way to do something like this?  Is there a different way to
 do it that I've just overlooked and I'm making things harder than they
 need to be?

Re: Tapestry 4.1 injecting the wrong application state object

[Pepijn Schmitz]

Hi,

Thanks! But I don't think that's it. We're already using HTTPS, but also 
that would not explain how the correct application state object can be 
on the HttpSession, even though Tapestry injected the wrong one...


We are using Apache 2 using mod_proxy as a front-end though. Apache 
takes care of the SSL and forwards the requests to Glassfish over HTTP. 
I'll look into the possibility that something is going wrong there, 
although it seems unlikely due to the above reason...


Cheers,
Pepijn

even with HTTPS we just left everything as is.

Hence I'd suggest temporarily requiring HTTPS for the whole site and if the

Good luck.

Hi everyone,

I'm having a bizarre problem with Tapestry, and I'm hoping someone here
might be able to point me to a solution. Before I go into detail I'd like to
describe the problem generally, in the hopes that it might be a known
problem or someone may have encountered something similar.

The problem is that Tapestry 4.1.6 sometimes injects the wrong application
state object on my pages! As you can imagine, this plays havoc with my
application, with users seeing other users' details, or even worse, changing
other users' information! It's a support and security nightmare.

I'm using Tapestry 4.1.6, and I'm using annotations instead of XML files.
My pages all descend from a base class:

public abstract SupplierDNAPage extends BasePage {
@InjectState
public abstract SupplierDnaSession getSupplierDnaSession();

@InjectStateFlag
public abstract boolean getSupplierDnaSessionExists();

...
}

hivemodule.xml contains the following:

?xml version=1.0 encoding=UTF-8?
module id=com.supplierdna version=0.0.0
contribution configuration-id=tapestry.state.ApplicationObjects
state-object name=supplier-dna-session scope=session
create-instance class=com.supplierdna.logic.SupplierDnaSession/
/state-object
/contribution
  ...
/module

SupplierDNA is the name of the company I'm writing this for. As I
understand it, this is the correct way of using application state objects.
And most of the time, it works perfectly. When testing locally I have no
problems with wrong application state being injected, and our demo system
also doesn't have the problem.

The problems seem to start when the server is heavily loaded. Then,
sometimes, getSupplierDnaSession() will return an application state object
from a different session!!!

I have verified this by adding a pageBeginRender() listener method to the
base class, and a client address property to the session. The listener
method checks whether the client address stored on the session it gets from
Tapestry is the same as the client address from the current request, and
throws an exception if this is not the case. On our production server, this
happens dozens of times a day!

The method also directly retrieves the application state object from the
HttpSession and compares it to the one it got from Tapestry, and it turns
out that the application state object on the HttpSession is the correct one,
but somehow Tapestry is injecting a different one! This seems to rule out
the web container as being the culprit (which is Glassfish 2 update 2, in
this case).

Hi,

I've been using jetty with live reloading working just fine.

however i've just started using javascript files located in my 
src/main/resources dir via the @Import annotation:


@Import(library = MyScript.js)
public class MyPage
{}

src/main/resources/basepackage/pages/MyScript.js

After editing the js (between 2 and 5 times) I get a red cross on my 
project in eclipse and jetty is broken in that it can't respond to requests.


only after stopping jetty and doing a project clean can i get it to work 
again.

Spring SymbolProvider breaks when upgrading from 5.1.0.5 to 5.2.4

[Ólafur Freyr Hjálmsson]

Hello


My application is using Hibernate for the database with Spring wired
services for business logic and Tapestry for the UI.

To customize the database access and image base url and the like, I use
multiple properties files for configuration, loaded from the filesystem or
classpath depending on which system should be accessed.

This is achieved by implementing a Spring PropertyPlaceholderConfigurer
which exposes properties using the expression syntax (${key}) for use in
applicationContext.xml.

Accessing these same properties in Tapestry is possible by implementing a
SymbolProvider and connect that to the SymbolSource in my AppModule.


This worked fine in Tapestry 5.1.0.5 using Spring 2.5.6 but broke down when
I upgraded to Tapestry 5.2.4 using Spring 3.0.5.

The workaround to use the servlet
context-param tapestry.use-external-spring-context works fine, but I would
like to understand why that is needed.


The closest I came to getting it to work without reporting errors was to
contribute to SymbolSource using this in my AppModule:


public static void
contributeSymbolSource(OrderedConfigurationSymbolProvider configuration,
ObjectLocator locator) {

configuration.add(SpringSymbolProvider,

locator.proxy(SymbolProvider.class, SpringSymbolProvider.class),

after:ApplicationDefaults);

}

This throws no exception and works but reports an error in the log:

ERROR 2011-01-11 20:03:03,179 [main] (OperationTrackerImpl.java:108) -

Realizing service ApplicationContext

Seems like the Tapestry service ApplicationContext which provides access to
Spring beans depends on SpringSymbolProvider which uses ApplicationContext
to provide the Spring symbols. Catch-22.
Tapestry seems to recover from this and eventually instantiates the services
properly.

As far as I understand the clever use of proxy objects and on-demand
instantiation of Tapestry services, this should be possible if I can inject
the objects properly (correct order or use of @Inject or constructor
arguments).
The reason I think so is that the above errors appear when
SpringSymbolProvider accepts an ApplicationContext reference in
the constructor and uses that object to load the properties immediately
after which the object is discarded.

When instead using @Inject to instantiate an ApplicationContext member which
is used only when requesting a valueForSymbol, the properties don't get
translated and the following errors occur:

ERROR 2011-01-11 20:16:34,010 [main] (OperationTrackerImpl.java:108) -

This strikes me as quite weird, ApplicationContext cannot be injected and no
exception is reported.

I would appreciate it if someone has any hints for me as I prefer to use the
more integrated approach.

Thanks in advance.

Re: Context of a Zone

[Mark]

Thanks for your suggestion. It sounds like I'm not overlooking
anything obvious. :)  Redrawing the entire loop works with some
issues. I figured if it was capable of redrawing the entire loop then
I should be able to get access to what I need to redraw only certain
parts of it.

The problem I'm having with redrawing the whole loop is that now my
text field is part of what is being redrawn and this is introducing
two other issues:

1. All text fields update, which isn't desirable because it highlights
the entire table instead of just what changed. (My end goal was to
only update the zones that had changed.)

2. It also isn't ideal with a long list.

3. The text field loses focus after the first keyup so it is
impossible for anyone other than Superman to type more than one digit
before the text field loses focus.

I can live with items 1 and 2, but the prospects of only letting
Superman use this application are slim. So #3 is probably the big
issue.

I can't seem to tell the zone update to return focus to the last
updated field.  I'm using the javascript described here:
http://tinybits.blogspot.com/2010/03/new-and-better-zoneupdater.html)

And I've tried adding:
this.element.focus();
To the last line of updateZone : function() but it doesn't seem to do
anything.  I AM able to set the focus to a field that is outside of
the updated zone, so my guess is that the zone update is somehow
making it lose focus.

 You have a single zone component and when doing a multi-zone update
 you want to simulate a loop to get different content rendered for that

 reasonable use case.

 If your change is modifying all the prices, could you just re-draw the
 whole table with an outer zone?

 I have a form with a loop that looks something like this:

 |__QTY__|_ITEM__|__PRICE__|
 |__1_|_soup__|$1|
 |__3_|_peas__|$3|
 etc.

 Users can change the quantity and it automatically changes the price.
 Each price is in its own zone and the KeyUp action on the
 cooresponding QTY causes that price zone to update. (I'm using the
 zoneUpdater described at
 http://tinybits.blogspot.com/2010/03/new-and-better-zoneupdater.html)

 Now the requirements have changed and we need to be able to offer a
 discount based on the number of items being purchased.  This means
 that an update to the soup row will sometimes need to change not only
 the price soup row, but also the peas row. At first I tried building a
 MultiZoneUpdate (Thank you for your help Josh), but that just sets
 every price to the same thing as the row that is being updated. This
 is because the context of the row/event that triggered the updated
 doesn't provide the context for the zones that need to be updated. If
 I change the Qty of soup to 2, the soup item is the context for that
 update, so when I update the row for peas, that zone doesn't know
 anything about peas--only soup.

 So my question is:
 How can I access an item from the context when the zone was rendered
 instead of the context of the section that is triggering the zone
 update.

 It seems like I could solve this if each zone was rendered with a
 context that could be used when an update was triggered on that zone.
 Something like:
 t:zone t:context=item t:id=priceZone id=priceZoneId
 ${itemSubtotal}/t:zone

 The idea being, that when you update a zone, it can figure out the
 context at which the zone was originally created and not just the
 context of the event firing the update. (Of course I don't know how
 this would work on the Java side of things.)

 Is there a way to do something like this?  Is there a different way to
 do it that I've just overlooked and I'm making things harder than they
 need to be?

You might try running mvn jetty:run from the command line and see if
the problem only happens in Eclipse?  I've been doing something
similar all day and haven't had any problem, but I don't run Jetty

Re: attn howard: live reloading breaking using jetty

[Paul Stanton]

dammit, it seems like it is my classpathentry .. removed that and i 
can't break the reloading.


not sure why this causes a problem .. it wouldn't be jetty locking the 
source files would it?


would jetty be locking the output files? (target/classes...)

would changing the classpathentry so that it has it's own 'output' 
location help?


i really like having a classpath entry as it flattens the view in the 
eclipse package explorer...

Re: Context of a Zone

[Josh Canfield]

 Thanks for your suggestion. It sounds like I'm not overlooking
 anything obvious. :)

Well, at least not obvious to me!

 Redrawing the entire loop works with some
 issues. I figured if it was capable of redrawing the entire loop then
 I should be able to get access to what I need to redraw only certain
 parts of it.

Yeah, I agree. I have to believe that given time we could come up with
an elegant solution...

 3. The text field loses focus after the first keyup so it is
 impossible for anyone other than Superman to type more than one digit
 before the text field loses focus.

Can you trigger the update via onchange instead of keyup? I'm not sure
how to keep the focus, or why it's being taken away...

 parts of it.

 The problem I'm having with redrawing the whole loop is that now my
 text field is part of what is being redrawn and this is introducing
 two other issues:

 1. All text fields update, which isn't desirable because it highlights
 the entire table instead of just what changed. (My end goal was to
 only update the zones that had changed.)

 2. It also isn't ideal with a long list.

 3. The text field loses focus after the first keyup so it is
 impossible for anyone other than Superman to type more than one digit
 before the text field loses focus.

 I can live with items 1 and 2, but the prospects of only letting
 Superman use this application are slim. So #3 is probably the big
 issue.

 I can't seem to tell the zone update to return focus to the last
 updated field.  I'm using the javascript described here:
 http://tinybits.blogspot.com/2010/03/new-and-better-zoneupdater.html)

 And I've tried adding:
 this.element.focus();
 To the last line of updateZone : function() but it doesn't seem to do
 anything.  I AM able to set the focus to a field that is outside of
 the updated zone, so my guess is that the zone update is somehow
 making it lose focus.

 Any ideas?

onChange will fire the update, but it requires the user move the focus
out of the changed textbox to do the update. Like I said this isn't
being designed for superman and the users probably aren't going to
understand why it didn't update at first and then miraculously updated
when they did something else.

It seems like this wouldn't be to extreme of a use case, so there must
be someway to get it to work.
