RE: Memory consumption in T4.1.2 - Hard data

[Marcus.Schulte]

But that POM does use snapshots.
You shouldn't need the repository
http://people.apache.org/repo/m2-snapshot-repository
at all.
Probably, there are no very significant differences between the latest
4.1.2 snapshot and the release. But nevertheless, for a productive
environment, I'd always go with a released version.

what seems 

to be a "memory leak" in our Tapestry application for about a 
month since we upgraded to T4.1.2.  I won't bore you 
  
with the saga 

of the last month, but I would like to present the data I've 
gathered and look to the list for a proposed solution.  I was 
reading a recent thread in which Jesse said (08/09/2007):




"There is a map that grows as large as the system using it 
internally to javassist of various cached reflection 
  
info - but it 


doesn't leak in any way."

This is precisely what I've found in profiling our 
  
application and 


it
*appears* to be this map that is causing our applications to 
eventually run out of memory.


The YourKit profiler shows me that, as time goes on, 
  
there is an 

instance of HiveMindClassPool  that grows and grows as class 
instances are created.  This class extends from 
javassist.ClassPool and is the map that Jesse is 
  
talking about in 

his quote above.  And he's right, I wouldn't say that the class 
pool "leaks" either because it looks like it's designed 
  
to retain 


that memory until the class pool itself is no longer needed.



Take this quote from the javassist.ClassPool javadocs:

"Memory consumption memo:
ClassPool objects hold all the CtClasses that have been 
  
created so 

that the consistency among modified classes can be guaranteed. 
Thus if a large number of CtClasses are processed, the 
  
ClassPool 

will consume a huge amount of memory. To avoid this, a 
  
ClassPool 

object should be recreated, for example, every hundred classes 
processed. Note that
getDefault() is a singleton factory. Otherwise, detach() in 
CtClass should be used to avoid huge memory consumption. "


This huge memory consumption by the ClassPool is what I was 
seeing. In particular it is the ClassPool that is held 
  

onto by OgnlRuntime.

Inspecting this object in the profiler showed that it has a map 
containing about 45,000 classes.  All of the keys into this map 
were things like:  "ASTTest_11494aca9af" and 
  
"ASTAnd_11494ace4fb"

Re: T4.1.2 / Spring 2.0.6 / Hib3 Lazy loading and PropertySelectionModel stuff

[Marcus Schulte]

One thing to be aware of is that the same db-row, in two different
Hibernate-Session, corresponds to two different objects. So with
session-per-request, if your PSModel is loaded in one request, and your
value-parameter-object in another. If you don't override
Object.equalsappropriately, Tapestry cannot know which list member to
show for a given
value.

there's available options etc.). So we may conclude this Component has 
not been tested outside FireFox :)

T5's Palette buttons do not work on Opera either. They are rendered 
with disabled="disabled", something that is very strange. The same is 
rendered to Firefox, but in Firefox it works. It seems to me that 
Opera is doing the right thing (ignoring clicks in a button declared

Re: T5 Error in 5.0.5 palette.js

[Martin Reurings]

I suppose I'd have to make the time to test through the Palette 
component to figure this one out. The syntax appears to be correct 
(apart from the trailing comma you already identified) and the lack of 
comments obscures a lot of what's going on.


There's some (to me) really obscure eventhandling going on which doesn't 
really help in understanding what could be going wrong :) My guess would 
be that IE doesn't change the state of something quite in the way 
FireFox would (judging from the bug you already solved it wasn't tested 
in anything else) and as a result you now don't have a set of objects to 
move, or something along those lines. Think along the lines of events 
which in FF are global, while in IE they only fire on the element.


Probably the best way to get some clarity is by adding a few alerts in 
some key places and compare the results of those alert between FF and 
IE. Just because it works in FF doesn't mean it's correct BTW.


I'm certain it's not a matter of syntax though!

Re: T5 Error in 5.0.5 palette.js

[Martin Reurings]

Without having a look at the rest of the code I can tell you without a 
doubt you are on the right track there.
When using Object Notation Firefox has some weird parsing error which 
allows it to successfully parse an object that has the illegal syntax 
you just highlighted. Make no mistake though, only Firefox is capable of 
this, Opera probably chokes on it and I know Safari will for sure.


If you'd be developing using Eclipse it may help to open up that JS code 
in JSEclipse (Free download from Adobe), it has a reasonably 
well-behaving syntax checker, it might help you fixing up the syntax :)

I think the extra comma after the end of the reorderSelected code block is

For me it was causing an error in IE6 which prevented me from using the
select button in the Palette.

I removed the "extra" comma, but then when I highlight some items and click

Is the T5 Palette working fine for anyone using IE?
The IE Version I am testing is
6.0.2900.2180.xpsp_sp2_gdr.070227-2254


Everything works fine in Firefox, of course.

Hi,

is there a way to use messages with parameters directly from a HTML
template?

Something like:

${message:results,prop:numberOfDatasets}

with

Page.java

...
public int getNumberOfDatasets()
{
  return numberOfDatasets;
}
...

Page_en.properties:

results:Found %d datasets.

Page_de.properties:

results:%d Datensätze gefunden.

If not, does this seem difficult to implement?

Thanks,

T4.1.2 / Spring 2.0.6 / Hib3 Lazy loading and PropertySelectionModel stuff

[Jan Vissers]

Hi,

I'm witnessing some 'interesting' behavior, using lazily loaded
collections (Hibernate) combined with PropertySelectionModel stuff. Before
getting into too much detail - using my JUnit tests I can prove that
traversing the (nested) objectgraph actually has the information (albeit
via CGLIB proxies). When using this in my T4.1.2 page however, I see that
the correct poplist value doesn't get selected. In a read only version of
the page on the other hand - where the poplist is dynamically replaced by
a readonly display item - the information is shown.

Is there something that I should be aware of in using T4/Hib3 regarding
the selectionmodel component?

-J.

BTW: I'm using OpenSessionInView provided by Spring.

Something I really miss in Grid that is present in T4's contrib:Table  
flexibility  
(http://tapestry.apache.org/tapestry4.1/tapestry-contrib/componentreference/table.html),  
specifically the columns parameter. That's why I'm developing an  
application en T5 and I'm not using Grid yet: it doesn't allow me to  
reorder the columns easily. I tried to grok the BeanModel default  
implementation, but I had to have a working code quickly and then I  
postponed my BeanModel hackings. :)

[T5] Usage of Grid component

[Christoph Jaeger]

Hi,

is there a simple example of how to use the grid component, which is
just a bit more complex than



There are basically two things I am looking for at the moment:

1. hide columns (without using annotations in the java files, my feeling
is that the configuration which fields to show on the web-form does not
belong in an annotation in the java entity, but in the page)

2. create a link (actionlink?) in each row to reach a page where the
specific item can be edited

I think almost every tapestry application will use features like this in
a grid, but I could not find a simple example of how to do it.

I someone points me to the right direction, I will create a simple
example for the wiki.

Thanks,

Christoph Jäger

Re: T5 Conditional New Window on submit

[Josh Canfield]

When you submit a form with target set to _blank the new window is
opened and the form is submitted there. The current page is not
refreshed. If you want to see the errors in the original window and
only open a new window you after the input is known to be good then
you have to post back to the same page and allow it to reload. If the
input is good then open the new window with the report.

I can't think of a way to do that without some javascript...

dojo widget question - where is StretchPane.js ?

[Ken nashua]

Folks,

There is planey of support since October 2006 of a widget named Stretchpane 
which optimizes or emulates a variation of css overflow:visible and 
basically automates it for parent container widgets/elements.


I checked out the latest dojo from http://svn.dojotoolkit.org/dojo/trunk

But StretchPane is no where to be found.

Can anyone elaobrate... thanks.

T5 Conditional New Window on submit

[Daniel Jue]

Right now I have a form that opens a new window on submit, like this:







The error processing it does is all server side.  However, if there is an
error, it will open a new window and show the form's page, including the
errors.
At this point I have duplicate forms, and one shows the error.

I want to only open the next page in a new window "on Success"  Is this
possible?  Do I need to be using Javascript for this?

Thanks,
Daniel

Off the top of my head I would suggest adding your javascript to the
onload event.

Event.observe( window, 'load', function() {
  // Put the Javascript that needs to happen when the page
  // loads here
} );

T5 Tree Component javascript and DOM

[Daniel Jue]

It figures that I would run into this problem.  Placing the Tree Component's
java script block, as seen on the wiki, can cause Abort errors on IE (tested
ie6) because it's modifying the DOM before it is loaded all the way.  (I am
using a larger, complex page to experience these errors)  My page probably
has 30-40 components on it, and the Tree I have is right in the middle of
that stack.

To remedy the problem, I put the 7 lines of javascript code at the bottom of
my border component, to make sure it always goes last.


treeObj = new JSDragDropTree();
treeObj.setTreeId('reporttree');
treeObj.setImageFolder('/IEIS2/images/tree/');
treeObj.setRenameAllowed (false);
treeObj.setDeleteAllowed(false);
treeObj.initTree();
treeObj.expandAll();



But for pages that don't have a tree on them, I get a script error because
JSDragDropTree is undefined.

Does anyone have a better solution for this?  This must have been solved
elsewhere...
Is there a hook in prototype we can use for making things run after the DOM
is complete?  The problem doesn't happen with Firefox 2.

RE: How do I get a page from a sub-package

[Marcus.Schulte]

page-pathes are always relative to your pages-package, so
cycle.getPage("admin/UserList") should be fine.
Somehow, Tapestry seems to find your template in
/admin/UserList and associates it with BasePage.
Could it be, that you have a page class named UserList in both the pages
package and the admin sub-package? Maybe a dirty build after moving
thins around?

Re: Memory consumption in T4.1.2 - Hard data

Umm yeah.   I have looked in to it as I just said.

The only thing left is for me to look at this youkit snapshot profile
and play from there but I'm not capable of debugging issues that
aren't reported properly.

Hi Jessie

I'm gonna try update my version of ognl, if that won't work I will 
downgrade. I have not filed any bugs yet, but I sent a couple of emails 
to the list.  I don't get any exceptions during development, but that is 
because its not running for 3 or 4 days. I strongly suggest you consider 
looking into it, because I use the standard libraries provided by 
Tapestry through Maven.


my configuration is as follows:

JDK 6.01 32bit JVM (I have also tested on a 64 bit with no luck)
Tomcat 5.5.20
Debian Linux (2.6.15.28 kernel)
Tapestry 4.1.2-SNAPSHOT with ognl 2.7

Peter

The OGNL classes indeed aren't being kept in the javassist pool from
what I can tell.

I have another yourkit snapshot binary to look at so we'll see what that says.

I don't remember - have you filed any bug reports or reported any
problems?  Are you getting ognl exceptions during development as well
as production?  Do these errors sound like umpotential errors
that should be looked at further?

I and another colleague of mine have been investigating what seems to be
a "memory leak" in our Tapestry application for about a month since we
upgraded to T4.1.2.  I won't bore you with the saga of the last month,
but I would like to present the data I've gathered and look to the list
for a proposed solution.  I was reading a recent thread in which Jesse
said (08/09/2007):



"There is a map that grows as large as the system using it internally to
javassist of various cached reflection info - but it doesn't leak in any
way."

This is precisely what I've found in profiling our application and it
*appears* to be this map that is causing our applications to eventually
run out of memory.

The YourKit profiler shows me that, as time goes on, there is an
instance of HiveMindClassPool  that grows and grows as class instances
are created.  This class extends from javassist.ClassPool and is the map
that Jesse is talking about in his quote above.  And he's right, I
wouldn't say that the class pool "leaks" either because it looks like
it's designed to retain that memory until the class pool itself is no
longer needed.



Take this quote from the javassist.ClassPool javadocs:

"Memory consumption memo:
ClassPool objects hold all the CtClasses that have been created so that
the consistency among modified classes can be guaranteed. Thus if a
large number of CtClasses are processed, the ClassPool will consume a
huge amount of memory. To avoid this, a ClassPool object should be
recreated, for example, every hundred classes processed. Note that
getDefault() is a singleton factory. Otherwise, detach() in CtClass
should be used to avoid huge memory consumption. "

This huge memory consumption by the ClassPool is what I was seeing. In
particular it is the ClassPool that is held onto by OgnlRuntime.
Inspecting this object in the profiler showed that it has a map
containing about 45,000 classes.  All of the keys into this map were
things like:  "ASTTest_11494aca9af" and "ASTAnd_11494ace4fb" and the
values are instances of javassist.CtNewClass.  Each entry in this map
looks like it retains about 1,900 bytes, for a grand total of about 90
MB of memory used.

These numbers came from my staging deployment where I had the profiler
attached, using some reflection tricks I was able to look at a
production site and found that it had about 240,000 items in that class
pool.. approximately 450 MB of memory.

So I guess the questions in my mind are:  Why are there so many classes
in the pool?  Why does the number only ever go up?  Do those classes
really need to stay in the pool forever?

Even better: you need to submit the form when the user selects a different  
value of A, so you know what value was chosen.

The submitForm property of @EventListener does the trick:

@EventListener(targets = "A", events = "onchange", submitForm="form")
public void onChange(IRequestCycle cycle, BrowserEvent event) {

Looking at the Javadocs of the latest snapshot, it looks like you won't  
need to specify submitForm anymore.

Try to make A persistent:

@Persist
public abstract String  getA();

Your getA() returns null because the request that renders the form is one  
and the EventListener call is another. ;)
Any value stored in Tapestry class properties, unless explicitly made  
persistent, is lost when the request finishes.

How-to update a selection model based on a prior selection

[Marcos Chicote]

Hello,

I'm trying to update a selection model based on a prior selection, using
AJAX
and Tapestry 4.1.1.

I've built a small test case, connecting an EventListener to the onchange
event
of a PropertySelection. You can find it at the end of this mail.

In the test, the EventListener is properly called (when the value of the
PropertySelection is changed), but the selections are not updated. When
called
from Test.onChange(), Test.getA() returns 'null' instead of the selected
value.

Somebody knows what should I write in the EventListener to get the
selected value?.

Thank you very much, best regards.

Re: T5:Tiles?

[Angelo Chen]

Hi Josh,

I tried to folow following method, but not working:

my Layout.java like this:

public class Layout {

@Parameter
private Block _sidebarContent;

public Block getSidebarContent() {
return _sidebarContent;
}

public void setSidebarContent(Block sidebarContent) {
this._sidebarContent = sidebarContent;
}

@Parameter
private String _title;
public String getTitle() {
return _title;
}

public void setTitle(String title) {
this._title = title;
}
  
}

in my Somepage.html


i noticed the setter in Layout.java will not be called, why? thanks.

A.C.






or you can add the title parameter to Layout and pass it from Somepage

Layout.java:
@Parameter // if you want to require a title, add (required=true)
private String title; // add getter/setter

Somepage.html

...

Re: How do I get a page from a sub-package

I have the following configured:



Are you saying I should change it to:



Are you sure it doesn't scan sub-packages by default? It seems to - if I put
a class in this package and move the page into a matching sub-directory, it
works. However, when I get a page from the IRequestCycle, I don't know how
to traverse into the sub-package (or above the current package for that
matter).

Re: Memory consumption in T4.1.2 - Hard data

[Jesse Kuhnert]

I'd downgrade then if I were you.   Extensive profiling with yourkit
hasn't shed any new light on whatever problems others are having.
The OGNL classes indeed aren't being kept in the javassist pool from
what I can tell.

I have another yourkit snapshot binary to look at so we'll see what that says.

I don't remember - have you filed any bug reports or reported any
problems?  Are you getting ognl exceptions during development as well
as production?  Do these errors sound like umpotential errors
that should be looked at further?

Re: T5:If component

[Nick Westgate]

The If component's test parameter is a boolean:
http://tapestry.apache.org/tapestry5/tapestry-core/component-parameters.html

You need to make your accessor non-private:
public boolean getLoginned() {
 return true;
 }

And the default binding is prop, so no funky OGNL-like stuff:
  
   

Cheers,
Nick.

It's not the file name. The problem is: as soon as you add a upload 
component to a form all other text fields (in the same form) are not 
decoded with the request encoding. 
So, you cannot have text fields and an upload in one form (with UTF-8
encoding).

Chris

Not everyone is using tapestry-upload and not everyone is using fancy

Subject: Re: Memory consumption in T4.1.2 - Hard data


Andreas, give me a break! I am not trying to trash Tapestry 
if that's what you are thinking. I am not the only one 
experiencing these problems.
Have a look at some of my postings (and others posts) and you 
will see what I am talking about. I have been having these 
problems since upgrading from 4.1.1 I never experienced these 
problems before with uptime of months at a time.


Look at this log, id is an integer with the value 728:

21 Aug 2007 13:01:49,353 - INFO $Portfolio_89 - Setting the 
portfolio with the id: 728

n(ExpressionBinding.java:145)
	at 
org.apache.tapestry.binding.ExpressionBinding.getObject(Expres

And then take a look at this:

21 Aug 2007 07:56:50,613 - ERROR

add method java.lang.Object get(ognl.OgnlContext, 
java.lang.Object) to class $ASTProperty_1146a471a52: [source 
error] no such class: $Exception_119


This happening after 3-4 days of normal operation? Suddenly 
exceptions occur on random objects because OGNL can no longer 
compile them and this is because Tapestry can no longer find 
instances of these classes, it relates to JavaAssist dynamic 
class loading. Also, currently  the server is idle with no 
connections and JConsole shows 18000 classes loaded, 
yesterday there were 7000 classes, this number never goes 
down only up, so you tell me what's going on?


If Jessie can't explain it, then I have to go back a version 
we cant afford for clients to see broken pages, my boss 
doesn't care about the problem, he just wants a solution and 
its my job and reputation is at stake.

Hey - i never meant that!

It's obvious from the reports that something's going on + Jesse was on to
it..
I just thought i'd offer a counter-example + throw in an example
of a T4.1.2 public site ( i'm not aware of a lot)

Re: Memory consumption in T4.1.2 - Hard data

[Kalle Korhonen]

Now that's an OGNL compiler error. Have you tried with OGNL
2.7.1-SNAPSHOT(just use the latest). OGNL
2.7 that comes with Tap 4.1.2 by default is known to have bugs with the
compiled expressions. Please try with the latest OGNL; it might just do the
trick.

Re: Memory consumption in T4.1.2 - Hard data

[Peter Stavrinides]

Andreas, give me a break! I am not trying to trash Tapestry if that's 
what you are thinking. I am not the only one experiencing these problems.
Have a look at some of my postings (and others posts) and you will see 
what I am talking about. I have been having these problems since 
upgrading from 4.1.1 I never experienced these problems before with 
uptime of months at a time.


Look at this log, id is an integer with the value 728:

21 Aug 2007 13:01:49,353 - INFO $Portfolio_89 - Setting the portfolio with the 
id: 728
21 Aug 2007 13:01:50,479 - ERROR $Error_118 - Unable to parse OGNL expression 
'id': Unable to parse OGNL expression 'id': Unable to parse OGNL expression 
'id': 
Exception [classpath:/org/apache/tapestry/form/TextArea.jwc, line 49, column 67]
at 
org.apache.tapestry.binding.ExpressionBinding.resolveExpression(ExpressionBinding.java:145)
at 
org.apache.tapestry.binding.ExpressionBinding.getObject(ExpressionBinding.java:125)

And then take a look at this:

21 Aug 2007 07:56:50,613 - ERROR 
org.apache.tapestry.services.impl.HiveMindExpressionCompiler - Error generating 
OGNL getter for expression exceptions with root [EMAIL PROTECTED]:Exception] 
and body:

java.lang.Object get(ognl.OgnlContext, java.lang.Object) to class 
$ASTProperty_1146a471a52: [source error] no such class: $Exception_119

This happening after 3-4 days of normal operation? Suddenly exceptions 
occur on random objects because OGNL can no longer compile them and this 
is because Tapestry can no longer find instances of these classes, it 
relates to JavaAssist dynamic class loading. Also, currently  the server 
is idle with no connections and JConsole shows 18000 classes loaded, 
yesterday there were 7000 classes, this number never goes down only up, 
so you tell me what's going on?


If Jessie can't explain it, then I have to go back a version we cant 
afford for clients to see broken pages, my boss doesn't care about the 
problem, he just wants a solution and its my job and reputation is at 
stake.

Yes, just use the @Secured("ROLE_ADMIN") annotation on the page class
and the framework takes care of the rest.

Re: How do I get a page from a sub-package

[Martino Piccinato]

I think you can use configuration parameter

org.apache.tapestry.component-class-packages

(from documentation) A comma-seperated list of package names, used
when  searching for the component class  . These must appear as 
 tags in the application or library specification containing the
component


For other options you can see

http://tapestry.apache.org/tapestry4.1/usersguide/components.html

at the section "Referencing Library Components"

Tapestry 4 to 5 page service

[Peter Stavrinides]

Hi all,

I am currently upgrading a Tapestry 4 app to Tapestry 5, I am still 
adjusting to the differences between the two frameworks. In Tapestry 4 I 
could retrieve a page link using the page service IEngineService like this:


final ILink pageLink = pageService.getLink(false, pageName);

I gather ILink no longer exists in T5 but there is PageLink instead, so 
what infrastructure or service can  be used to retrieve the PageLink 
using only the page name.


Thanks,
Peter

That's really cool and very useful!

To clarify my understanding - how does it deal with protecting
links/functions. For example, assume I'm a regular, non-admin user and
access the application. Since I'm not an admin, I don't see the link to the
"Clear database" function, but somehow, I can guess it's link. How does the
framework protect me from invoking that link anyways? Do you have equivalent
functions as ifLoggedIn and ifRole in the java class files?
