T5: FileUpload and time out
Hi,
following sample works, but how to determine if timeout error occurs?
thanks.
public class UploadExample
{
private UploadedFile file;
public UploadedFile getFile()
{
return file;
}
public void setFile(UploadedFile file)
{
this.file = file;
}
public void onSuccess()
{
File copied = new File(/my/file/location/ +
file.getFileName());
file.write(copied);
}
}

Localization in business objects
Hi, is it possible to use the Tapestry Localization (message catalog) outside of pages and components, e.g. in business objects creating reports? A simple @Inject private Messages messages; doesn't work. Of course Tapestry could supply messages from the main application catalog only, but since pages-specific catalogs are usually override existing application messages, that would be sufficient. If thats not possible we must minic the name-decoration used by tapestry to load the best matching properties file, or is there another approach? Thanks, Udo. -- Pt!

[T5] Using Autocomplete.configure to specify an afterUpdateElement function
Hi,
Although I can subclass Autocomplete and implement the configure(JSONObject)
method to specify an afterUpdateElement, the fuction I specify (as a String
here) gets surrounded by double-quotes by JSONObject.toString()
Thus it is not interpreted as a function. It would be nice if I could use
some object, JavascriptFunction for example, which would not be quoted by
toString().
protected void configure(JSONObject config) {
config.put(afterUpdateElement, function (element, selectedElement)
{element.blur();});
}
results in the following script:
new Ajax.Autocompleter(xxx, xxx:menu', '/xxx/xxx:autocomplete',
{indicator:xxx:loader,afterUpdateElement:function (element,
selectedElement) {element.blur();},paramName:t:input});
Should I create a JIRA issue for this?

Paudi

[T5] Rendering a block a component received as parameter
Hi there,
I am developing a tree component which can take several classes as
nodes. Each class should have it's own body, stored in parameters - and
then rendered, of course.
Now, lets say I have I have this code in my Test.tml:
--
t:ExTree t:id=taskTree source=treeNodes currentNode=currentTreeNode
t:parameter name=taskClassContent
t:pagelink t:page=Task
context=${ognl:currentTreeNode.id}${ognl:currentTreeNode.title}/t:pagelink
/t:parameter
t:parameter name=projectClassContent
t:pagelink t:page=Project
context=${ognl:currentTreeNode.id}${ognl:currentTreeNode.projectName}/t:pagelink
/t:parameter
/t:ExTree
--
As you can see, taskClassContent and projectClassContent are Block elements.
Now how can I render this Block element in my ExTree component? By the
way, ExTree hasn't a template, just a class.
Hope that someone can help me,
Tobias

Just add more parameters to the activate/passivate-methods.
Or you can use (Object[] parameters).
Or you can use (EventContext context)

Hello all,
I'm new to Tapestry 5, and I'm having some problems:
In T4, the Shell component creates the outer layout. When I insert a
shell component in my pages, it ignores the page htmlhead etc and
only
renderizes
the body, and renderizes the shell htmlhead.
On T5, with the t:layout, it renders both, the layout htmlhead
and
the page htmlhead.
How can I make it render only the layout htmlhead?
And how can I make so that it don't render something, like the
$remove$
tag on T4?
The tutorials I found about T5 shows examples with layout this way:
On the layout page, it goes the shell:
html
head
etc
On the page, just the body content, like:
t:layout xmlns:t=http://tapestry.apache.org/schema/tapestry_5_0_0.xsd
${hello}
/t:layout
But if I do this way, when I open the page on a web browser it doesn't
recognize it
as a html page. I have tried adding a
meta http-equiv=Content-Type content=text/html; charset=UTF-8/
It works for a preview, but when I run tapestry it throws this exception:
Failure parsing template context:Start.tml: The markup in the document
following the root element must be well-formed.
How are you doing to preview the pages?
Thanks.

[T5] Login session

T5: getting current hibernate session (per-thread) from singleton-service
I found some partial references on the list, but nothing that really answered
the question, so:
How can I get the current (per-thread) hibernate-session (as configured
through tapestry-hibernate) from a singleton custom tapestry service?
For reference:
I have a MySingleton-class build as a tapestry service.
MySingleton.getSingleton().getCurrentSession() should give me the current
session (thread-bound) as managed by tapestry-hibernate.
This would enable me to access the current session from any class (not just
components or tapestry services)
I tried 3 methods, 2 of which don't work, and 1 I'm not certain
Method 1:
build the MySingleton-class and inject Session at constructortime.
Problem: the hibernate session that is created on constructor-time stays
assoaciated with MySingleton (correct?). So this doesn't give a
session-per-thread.
Method 2:
build the MySingleton-class and inject HibernateSessionSource
getCurrentSession(){
return hibernateSessionSource.getSessionFactory().getCurrentSession();
}
Problem:
but this gives error:
org.hibernate.HibernateException: No CurrentSessionContext configured!
I think this happens because the way the session is accessed bypasses the
tapestry-hibernate session-in-view filter (HibernateSessionManager) which
takes care of providing the context.
Is there any way to make getSessionFactory() aware of the
HibernateSessionManager? So the above works?
Method 3:
build the MySingleton-class and inject ProperyShadowBuilder and
HibernateSessionManager
I figured this calling hibernateSessionManager.getSession() would give me
the needed context (which lacked from method 2) . The problem is that
HibernateSessionManager is not a singleton either.
I thought this could be bypassed by doing :
getCurrentSession(){
return shadowBuilder.build(hibernateSessionManager, session,
Session.class);
}
However this still doens't ensure (I think) that hibernateSessionManager
belongs to the current thread.
Can anyone shed some light on this? I would highly appreciate it!
Cheers,
britske

Re: [T5] Rendering a block a component received as parameter
I don't recall if you can use MarkupWriter to write blocks yet, but one
method I've used is to return the block from the beginRender method, it's
rendered after whatever you write within the method. I believe for both
blocks you would have to use both beginRender and beforeRenderTemplate, or I
suppose you could loop from the beginRender method.
If you want to wrap your blocks in an element you would start it in
beginRender and finish it in afterRender...
In the case you've laid out though, it might be easier to just create a
template.

As you can see, taskClassContent and projectClassContent are Block

Now how can I render this Block element in my ExTree component? By the way,
ExTree hasn't a template, just a class.
Hope that someone can help me,

[T5] : in place Grid does not sort when rendering a checkbox in a column
Hi, I have an inplace grid, enclosed in a form, and which renders a checkbox for a boolean attribute. (The code is at the end of this mail). My problem is that the grid refuses to sort its columns If I remove the rendering of the check box and just display the boolean value, sorting works fine If I set my grid to inplace:false, sorting works fine also After debugging it seems that the gridDataSource.getRowValue(i) is called just once for i=0, and not for the rest of the rows. Does anyone have the same issue ? Am I missing something ? Thanks, Hugues *Code :* t:form t:grid t:source=gridDataSource rowsPerPage=10 row=myItem pagerposition=bottom exclude=Id inPlace=literal:true reorder=selected, name, desc t:parameter name=selectedCell t:checkbox t:value=myItem.selected / /t:parameter /t:grid t:submit t:id=testSubmit value=test / /t:form

Re: T5: getting current hibernate session (per-thread) from singleton-service
How can I get the current (per-thread) hibernate-session (as configured
through tapestry-hibernate) from a singleton custom tapestry service?
I haven't tried creating a getInstance type method for my service classes,
but here is my understanding. The default scope for a service is singleton.
When your service is auto built by Tapestry the parameters to the
constructor are proxies to the actual implementation. When your singleton
service has a dependancy on a perthread service the proxy gives you the
correct object for the current thread. For instance, all of my DAO classes
are registered as a service receiving the Session. Sessions are opened and
closed with the request, so if you're trying to access it outside of the
request you'd be in trouble.

I have a MySingleton-class build as a tapestry service.
MySingleton.getSingleton().getCurrentSession() should give me the current

This would enable me to access the current session from any class (not just

I tried 3 methods, 2 of which don't work, and 1 I'm not certain
Method 1:
build the MySingleton-class and inject Session at constructortime.
Problem: the hibernate session that is created on constructor-time stays
assoaciated with MySingleton (correct?). So this doesn't give a
session-per-thread.
Method 2:
build the MySingleton-class and inject HibernateSessionSource
getCurrentSession(){

}
Problem:
but this gives error:
org.hibernate.HibernateException: No CurrentSessionContext configured!
I think this happens because the way the session is accessed bypasses the
tapestry-hibernate session-in-view filter (HibernateSessionManager) which
takes care of providing the context.
Is there any way to make getSessionFactory() aware of the
HibernateSessionManager? So the above works?
Method 3:
build the MySingleton-class and inject ProperyShadowBuilder and
HibernateSessionManager
I figured this calling hibernateSessionManager.getSession() would give me
the needed context (which lacked from method 2) . The problem is that
HibernateSessionManager is not a singleton either.
I thought this could be bypassed by doing :
getCurrentSession(){
return shadowBuilder.build(hibernateSessionManager, session,
Session.class);
}
However this still doens't ensure (I think) that hibernateSessionManager
belongs to the current thread.
Can anyone shed some light on this? I would highly appreciate it!

Re: T5: getting current hibernate session (per-thread) from singleton-service
If you are using tapestry-hibernate, the injectable Session service is
a perthread proxy. It can be shared across threads, but each method
invocation on the proxy is redirected to a real per-thread Hibernate
session.

Re: t5: pass few parameters to 2nd page
At the moment you should think of the @PageActivationContext as a
convenience annotation for you to use when you only want to place a
single value in the context. Personally I think it would make more
sense if you where able to use it for multiple values.
Maybe worth adding a JIRA for that?
For example, when multiple values are annotated they are added to the
context in alphabetical order.

Re: t5: pass few parameters to 2nd page
IMHO, this is not the easyest approach
I prefer to inject the next page, set it's attributes and then pass it
as the method's return... this way you can set as many parameters as
you like

Re: T5: getting current hibernate session (per-thread) from singleton-service
Wow I love that. Somehow I mistakenly thought it didn't work that way,
thanks.
As a related question :
is there a way to get the 'real' session instead of the proxy on a call to
getSession()
The reason I'm asking is that in a lot of cases I want to use (Hibernate's)
DetachedCriteria's, so I can make a criteria, pass that as a parameter to a
repository and let the repository get the current session and create a real
criteria. (For reasons of seperation)
This is done through detachedCriteria.getExecutableCriteria(getSession());
However this always gives a classCastException, like:
java.lang.ClassCastException: $Session_11b08fbaf1e cannot be cast to
org.hibernate.engine.SessionImplementor.
for a related post (similar problem) see:
http://www.nabble.com/Hivemind-creates-proxy-Hibernate-Session-td9845916.html
Therefore I need the 'real' object.
diong getSession().getSessionFactory().getCurrentSession() would solve my
problem, since that would be both the session of the current thread and the
real object, but (as described in method 2 of my post) the context assigned
to be tapestry-hibernate isn't there when accessing the session in this way.
Any suggestions on how to solve this as well? Much apreciated!

Hello all,
I'm new to Tapestry 5, and I'm having some problems:
In T4, the Shell component creates the outer layout. When I insert a
shell component in my pages, it ignores the page htmlhead etc and
only
renderizes
the body, and renderizes the shell htmlhead.
On T5, with the t:layout, it renders both, the layout htmlhead
and
the page htmlhead.
How can I make it render only the layout htmlhead?
And how can I make so that it don't render something, like the
$remove$
tag on T4?
The tutorials I found about T5 shows examples with layout this way:
On the layout page, it goes the shell:
html
head
etc
On the page, just the body content, like:
t:layout xmlns:t=http://tapestry.apache.org/schema/tapestry_5_0_0.xsd
${hello}
/t:layout
But if I do this way, when I open the page on a web browser it doesn't
recognize it
as a html page. I have tried adding a
meta http-equiv=Content-Type content=text/html; charset=UTF-8/
It works for a preview, but when I run tapestry it throws this
exception:
Failure parsing template context:Start.tml: The markup in the document
following the root element must be well-formed.
How are you doing to preview the pages?

If you want to wrap your blocks in an element you would start it in

In the case you've laid out though, it might be easier to just create a

Re: [T5] Rendering a block a component received as parameter
But you can't use a delegate component without a template, right?

I don't recall if you can use MarkupWriter to write blocks yet, but one
method I've used is to return the block from the beginRender method, it's
rendered after whatever you write within the method. I believe for both
blocks you would have to use both beginRender and beforeRenderTemplate,
or I
suppose you could loop from the beginRender method.
If you want to wrap your blocks in an element you would start it in
beginRender and finish it in afterRender...
In the case you've laid out though, it might be easier to just create a
template.

Re: t5: pass few parameters to 2nd page
I see a problem with multiple @PageActivationContext annotations inside a
page class.
Consider following example:
public class Start{
@PageActivationContext
private Foo b;
@PageActivationContext
private Bar a;
}
When Eclipse Sort Member Save Action feature is enabled, the order of
members a and b will change. The class will look like:
public class Start{
@PageActivationContext
private Bar a;
@PageActivationContext
private Foo b;
}
In this case the order of the parameters of the generated onActivate handler
conflicts with the order of the values of the ActionLink's context
parameter specified in the template.

T5: java.util.ConcurrentModificationException
On one page I use a persistent Hashmap. The page contains an actionLink with a click event handler. The onclick event is activated with a delay using setTimeout. When the event is fired another actionLink is activated. Now what happens is that during the handling of the first actionLink the second actionLink is activated and this results in a ConcurrentModificationException on the Hashmap. I can solve it by using a multithread safe Hashmap but I want to understand under what circumstances you need to be carefull for multi threaded activation (with Tapestry 5 that is). Should a Persisted variable always be multithread safe? I think so but what other Tapestry related items should be multithread safe as well?

Re: T5: java.util.ConcurrentModificationException
Does raise an interesting point. In a traditional page app, you would rarely have request overlap. It was possible (a wildly clicking user, perhaps). Often the main page would be one request, followed by a series of overlapping requests to retrieve static assets. It would be possible to add a filter to the page and component event request chains that would single-thread requests for any specific session. That would raise some additional problems; for example, an earlier user ran afoul of Tapestry's existing code (that single threads the system periodically, to check to see if any resources on the file system changed). They had a window where process of one request would loop back as a new request and thus two threads could end up deadlocked. So it does seem to me that if you are using Ajax techniques and thus explicitly asynchronous access to the application, you should be mindful of this. We could bounce around some ideas as to how the framework could assist: perhaps a per-session/per-page lock?

Re: T5: java.util.ConcurrentModificationException
So it does seem to me that if you are using Ajax techniques and thus explicitly asynchronous access to the application, you should be mindful of this. We could bounce around some ideas as to how the framework could assist: perhaps a per-session/per-page lock? A per-session/per-page lock still allows concurrent access to ASO's I guess? I think that making any 'globally' accessible objects (ie Persisted objects, ASO's...?) thread safe is the safest choice but I'm not sure if that works for everyone. Would it be possible to automatically create a thread safe wrapper (proxy) for a Persisted object (and ASO) that only allows single threaded access to that object? Trigger the auto wrapper when a specific annotation is added to the persisted object like @ThreadSafe (or something like that). You can then choose to make the object thread safe by yourself or let Tapestry make a thread safe wrapper for you.

Re: T5: java.util.ConcurrentModificationException
Also, maybe you should be using ConcurrentHashMap or other classes specifically made for multi-threaded access. And if you review the javadoc for that class, I think they discuss how they handle iterators in a multi-thread safe manner.. Howard Lewis Ship wrote: Does raise an interesting point.

T3 problem: spindle won't include the tap. .jars in the .war
I know most eyes are focused on T5, but people work with legacy apps as well so... I have a small application built on Tapestry 3.0.3. It compiles, and I can build a .war, but no matter what I try, the .war won't contain the tapestry jars. The app is supposed to work in a hosted environment, I would like it to be self-sufficient (i.e. pack all it's libraries in it's war) but I'm obviously failing. My project was built with eclipse+spindle. Tapestry Framework plugin defaults libraries are included in the project java buildpath, libraries tab, and are also checked on the Order and Export tab. On war deployment, I get ClassNotFoundExceptions mentioning the tapestry RequestFilter (if I recall correctly, can't try it out at the moment). Basically, I'm stuck and would very much welcome opinions and suggestions. Cheers, Tomislav - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I see a problem with multiple @PageActivationContext annotations inside a
page class.
Consider following example:
public class Start{
@PageActivationContext
private Foo b;
@PageActivationContext
private Bar a;
}
When Eclipse Sort Member Save Action feature is enabled, the order of
members a and b will change. The class will look like:
public class Start{
@PageActivationContext
private Bar a;
@PageActivationContext
private Foo b;
}
In this case the order of the parameters of the generated onActivate
handler
conflicts with the order of the values of the ActionLink's context
parameter specified in the template.

I thought that its main contribution to be able to use it for multiple

and not yet I understand why this functionality has not been implemented.
So, I agree for jira.

At the moment you should think of the @PageActivationContext as a
convenience annotation for you to use when you only want to place a
single value in the context. Personally I think it would make more
sense if you where able to use it for multiple values.
Maybe worth adding a JIRA for that?
For example, when multiple values are annotated they are added to the
context in alphabetical order.

why don't ?

I dont think you can use that with multiple values as the context :/

Or, you can use the new @PageActivationContext annotation for a
greater
simplicity

Just add more parameters to the activate/passivate-methods.
Or you can use (Object[] parameters).
Or you can use (EventContext context)
The way to go for you would be to just add more parameters to the
activate/passivate-methods.
2008/7/9 t [EMAIL PROTECTED]:
void onActivate(String message)
{
System.out.println(Another page is activated! The
message is: + message);
this.passedMessage = message;
}
String onPassivate()
{
System.out.println(Another page is passivated...);
return passedMessage;
}
This is the snippet that i got from t5 book on how to pass
parameter
from
first
page to 2nd page. if i need to pass more than 1 parameter to 2nd
pages,
how to
do it?

Re: AW: AW: AW: AW: Strange behavior of special characters
Try searching the bug tracker... I found http://issues.apache.org/jira/browse/TAPESTRY-607 'Output encoding problem with some versions of Tomcat 5' (btw, what's your servlet container?) and some others that may help... For the record, tapestry 3-4 used a custom resourcebundle loader that didn't require you to pass the properties through native2ascii... I think it used the ending of the file name of the property to determine the indended encoding allowing you to use UTF-8 and be done with it... That's also the reason why GWT gives credit to Tapestry in Help-About (they've reused the code) On 7/9/08, Sebastian Altmann [EMAIL PROTECTED] wrote: Ok seems like this won't get me anywhre. I just can repeat: All my properties filese are 100% encoded in UTF-8 (checked this in eclipse and in an external editor) and all umlauts are displayed properly (except in the special case described above). To this problem you mentioned concerning Java Properties Files and UTF-8 encoding i just can guess, that it seems that this problem doesn't inflict the usage of properties inside tapestry. After i did a lot of testing concerning encoding both on UNIX and Windows machines, i just can say that special characters in UTF-8 are display properly (except in the special case described above) as long you set the concerning meta information in .application or rather in .library properly.

You can use ÄÖÜß and so on with no problem in property files (we do it), just be very sure they are iso-8895-1 encoded. If you use Eclipse, right click on the file, open Properties and look at the Text file Encoding. Max -Ursprüngliche Nachricht- Von: Sebastian Altmann [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 8.

After you mentioned the first time that there are problems concerning properties files in UTF-8 I also found this and similar articles on the sam topic. I would quietly accept this, if my special characters were displayed wrong all over the application and in other applications too, but i can't understand why this should be a general Java problem even though in 99% of cases my special characters are displayed properly. Maximilian Weißböck wrote: The load and store methods load and store properties in a simple line-oriented format specified below. This format uses the ISO 8859-1 character encoding. Characters that cannot be directly represented in this encoding can be written using Unicode escapes ; only a single 'u' character is allowed in an escape sequence. The native2ascii tool can be used to convert property files to and from other character encodings. from http://java.sun.com/j2se/1.5.0/docs/api/java/util/Properties.html Max -Ursprüngliche Nachricht- Von: Sebastian Altmann [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 8.

Because we're running an application with utf-8 properties-files without any problems. This strange behavior can only be found in anatoher application.

The weird thing is that my encoding basically is ok, and this strange things happen just under certain circumstances. Another thing that confuses me is that for example in löschen not just the ö isn't displayed correct but also the 3 following characters (sch). This happens to every string with special characters (mostly not the next 3 but the next 2 characters ).
