Hi,

_rowsPerPage property which is used by the grid in the template
to determine its number of rows like this:
| table t:type=grid
| row=partner

| rowsPerPage=${rowsPerPage}

My _rowsPerPage property get set to the right value after
submit, however the grid seems to ignore any changes from the
default it has been created with. Could it be the rowsPerPage
setting is cached somehow? How can I get the component to honor
new settings?
Would it be possible to have the grid component in your page class
so that you can update the rowsPerPage property directly?

T5: getting list of assigned Mixins from component
hi all,
how can i get a list of assigned mixins from a component?
I've tried from within a mixin but getMixinClasses returns always
an empty list:
@InjectComponent private Component _component;
@Environmental private JavascriptApi _jsAPI;
public void afterRender() {
ComponentResources _resources =
_component.getComponentResources()
.getComponentModel().getMixinClassNames();
from within a component i tried it too with:
@Inject private ComponentResources resources;
with no luck. From what i could see from the code i need a
EmbeddedComponentModel instance but i did not succeed
in obtaining one :)

[T5] How to retrieve the id of an event emitter in handler method ?
Hello, I would like to know how I can retrieve the ID of the component which triggered an even when I'm in an event handler method ? Well, perhaps that my problem is not this problem, so there is a little background to help you to decide... In my application, I have to create a component to manage an editable list of string. The available (functional) actions are add a string, remove a string, edit string. I need to present the edit form so that all action can be done in the same page : 8--- (note: string? are input text field) | string1 | _delete_ | string2 | _delete_ | string3 | _delete_ _add_a_value _submit_change_ _reset_ 8--- So, there's no real problem to do this : in the html template, I used a form component, with a loop component which goes through the list. I want that if an user edit some field and then want to add/delete a value, his modification are kept, so _add_a_value_ and _delete_ are submit button. The template looks like : 8--- t:loop t:source=range t:value=index p input t:type=TextField/ t:submit t:id=remove value=Remove/ /p /t:loop t:submit t:id=add value=Add/ ... 8--- In the Java code, I have two event handler : onSelectedFromAdd() and onSelectedFromRemove(), and they are called when matching button are submitted. But for the delete button, I don't know which one was really submitted. I would be happy if I can retrieve the id of the submitted remove: I can generate it so that I can retrieve the matching value to remove. An other option would be to pass a context to the submit event, but I don't think it's possible... So, if you have any idea to help me, they will be well-appreciated...

Re: Help with handling exceptions while using Hibernate's open-session-in-view pattern in Tapestry
I just realized I had a bug relating to this yesterday and I could use a little help solving it. I think the solution is to force the hibernate session to flush before the response is committed, but I'm not sure how/where to inject that call into tapestry. If I knew where to make tapestry call my code, getting hibernate to flush is easy. I just spent a few minutes this morning trying to explicitly call response.sendError, but once the WebRequestServicer has called its service method, the response is committed so I get an IllegalStateException. In general, I think we should either use an open session in view or DAO approach, not a hybrid. The point of open session in view is that developers don't have to worry about transactional contexts, reenlistment and stuff like that. If you're throwing those gains away with separate request/response or listener/other transactions, you're better off letting DAOs manage transactions and getting the benefits of their narrower scope and cleaner definition of where transactions start and stop. Even if spring says it's ok to start a new transaction in a session where the previous transaction was rolled back, I think it's a bad idea. I use open session in view, which is one transaction per session in its entire lifetime. For daemon processes, a session will go through multiple transactions, but the moment something goes wrong, I start with a new session. -Steve Michael Sims wrote: Sorry again for the not 100% Tapestry related question, but I got such helpful responses from my last question, and it's clear that there are a lot of people on this list that have already solved these issues that I'm running into (and I'm getting jack from the Hibernate forums ;) )... I've implemented the open session in view pattern in my Tapestry application in the fairly conventional way. I inject a threaded Session via Hivemind using a service factory, and the service factory activates a transaction and creates a ThreadCleanupListener to commit() the transaction and close the session when the thread is done processing the user's request. So far so good. What I'm not sure how to do is handle situations where I may need to inform the user that their transaction failed. For example, let's say I have a typical CRUD application to create new users for my system, and I want to be able to correctly handle the scenario where an administrator attempts to create a new user with a name that is already in use (a primary or unique key violation). I can't simply let the ThreadCleanupListener handle the commit() in this case; if I do this, and an exception is thrown, it is too late to inform the user since the request has already been rendered. The Open Session in View page on the Hibernate web site [1] states that a good approach is to use two transactions in one Session. If I took this approach, I would attempt to commit the transaction in my listener method, and catch the exception thrown from the database, and convert this into a validation error which states that the username is already taken. The problem with this is that the Hibernate documentation is quite clear that if any exception occurs, the transaction should be rolled back, and the Session should be closed and discarded. Rolling back is not a problem, but if I close and discard the Session, I'm no longer using open session in view. I'll have to go to the trouble to initialize any lazy collections or proxies that the view might need before I attempt the commit, otherwise I'll get a LazyInitializationException. But I've read one of the Spring guys saying [2] that it's ok to begin a new transaction on the same Session that has been rolled back, if you're only using it to initialize lazy collections. This would be nice if it were actually true; it would simplify things for me quite a bit. But I hestitate to rely on that, since the Hibernate documentation says otherwise. Can someone with a bit more experience with give me some advice on how to approach this? Thanks in advance...

This is because Hibernate may want to lazy fetch things, e.g. relationships. In a second request and therefore a second session, you can merge your your detached instance using the Object merge(Object o) method of Session. The returned object has the same values as yours detached one, but it is associated with the session. Unless I'm mistaken, merge()'ing the same object into two different Sessions isn't any more safe than using update() or lock(), so you still have to deal with thread safety issues when using it.

The issue with that, in my case anyway, is that I'm using a SqueezeAdaptor to transparently squeeze a Hibernate persisted object into class + id, and then unsqueeze to the full entity on the next request. I do this for client persistence and direct link parameters, etc., to keep my objects from being serialized into the query string. My SqueezeAdaptor has to have an active session and transaction, and this occurs before any listener methods are called. I could have the SqueezeAdaptor, or anything else that needs to use Hibernate, start and finish their own transactions via DAO calls, but this would result in a high number of transactions per request, so I don't think that would be worth anything. Worse still, if any of those transactions results in an error, you are supposed to close the Session, which detaches all persistent objects and makes it impossible to access lazily-initialized properties.

Re: Help with handling exceptions while using Hibernate's open-session-in-view pattern in Tapestry
Keep in mind the difference between a flush and a commit in hibernate. A flush executes all the queued sql against the database without committing the transaction. Hibernate does this whenever it has changes that needed to be sent to the database before a query is run. Otherwise, it defers the flush until just before the commit. Unless you're using deferred constraints in oracle, constraint violations and other db-related exceptions will be raised during the flush, not the commit. What I'd really like to do is configure something in hivemind that would run just before tapestry commits the response. Then I could call session.flush() there to force the exception before the response is committed. I just don't know how I can accomplish this. -Steve Michael Sims wrote: Steve Shucker wrote: I just realized I had a bug relating to this yesterday and I could use a little help solving it. I think the solution is to force the hibernate session to flush before the response is committed, but I'm not sure how/where to inject that call into tapestry. If I knew where to make tapestry call my code, getting hibernate to flush is easy. If I need to commit or rollback the transaction in a listener method (or elsewhere), I inject a thread-bound transaction manager service into my pages. The transaction manager has the request-wide session injected into it, and I call methods on the manager to commit, rollback, etc. I got this idea from Tapestry 5's tapestry-hibernate project: http://tinyurl.com/3b3dok In my implementation, I have split out the ThreadCleanupListener responsibilities into another object, but the rest is pretty much the same. Does this help at all? In general, I think we should either use an open session in view or DAO approach, not a hybrid. The point of open session in view is that developers don't have to worry about transactional contexts, reenlistment and stuff like that. If you're throwing those gains away with separate request/response or listener/other transactions, you're better off letting DAOs manage transactions and getting the benefits of their narrower scope and cleaner definition of where transactions start and stop. The issue with that, in my case anyway, is that I'm using a SqueezeAdaptor to transparently squeeze a Hibernate persisted object into class + id, and then unsqueeze to the full entity on the next request. I do this for client persistence and direct link parameters, etc., to keep my objects from being serialized into the query string. My SqueezeAdaptor has to have an active session and transaction, and this occurs before any listener methods are called. I could have the SqueezeAdaptor, or anything else that needs to use Hibernate, start and finish their own transactions via DAO calls, but this would result in a high number of transactions per request, so I don't think that would be worth anything. Worse still, if any of those transactions results in an error, you are supposed to close the Session, which detaches all persistent objects and makes it impossible to access lazily-initialized properties. Even if spring says it's ok to start a new transaction in a session where the previous transaction was rolled back, I think it's a bad idea.

Re: Help with handling exceptions while using Hibernate's open-session-in-view pattern in Tapestry
I'm really fishing for a hivemind guru to tell me how to inject some code in the tail end of the WebRequestServicer.service() method. That would allow me to implement a general solution of flushing before the response is committed and forcing the exception to occur at a point where I can still notify the user. I want things to be automatic rather than having to explicitly call Session.flush() in every listener method. (If I was going to do that, I'd use an aspect.) I know this doesn't quite solve your problem because you want to use another session to render your error response. I'd consider a dedicated session in pageBeginRender of my error page (with some extra error handling) to set up the state for your error page. -Steve Michael Sims wrote: Steve Shucker wrote: Keep in mind the difference between a flush and a commit in hibernate.

Look at RequestCycleFactoryImpl and AssetEncoder to see where this happens. The short version is that the WebRequest should have a parameter set that identifies the tapestry service being called. What version of Tapestry? In 4.0.2, the pipeline calls the WebRequestServicerFilter's before the RequestCycleFactory and the encoders have done their work. With friendly URLs, a typical path for an asset is something like: /assets/031a6b16419c47ad157a817021baa2d6/class/path/file This is still the form it is in when it hits the filter. getParameterNames() returns an empty list, getParameterValue(ServiceConstants.SERVICE) returns null. I'm currently using the following to recognize an asset request: /assets.equals(request.getActivationPath()) You can verify this in the debugger by setting a breakpoint in both the filter and line 81 of RequestCycleFactoryImpl (where decodeParameters() is called), and then issuing a request for an asset. The filter will be reached first. The problem with this too, is that it's not immediately obvious that something is wrong. The filter will still do its job, namely synchronizing the requests, but it will do it unnecessarily in the case of the asset requests.

TapestryInternalUtils.urlDecode is invoked with the already decoded

This parameter is read from request.getServletPath(), which is already
/search/trüb. So it tries to decode the already decoded string, which
then fails.
What is the problem here? Is it that request.getServletPath() provides

private ServiceEncoder[] serviceEncoders;

WebRequestServicer servicer)
throws IOException {
// don't filter asset requests
ServiceEncodingImpl encoding = new
ServiceEncodingImpl(request.getActivationPath(),request.getPathInfo(),extractParameters(request));
for(ServiceEncoder serviceEncoder: serviceEncoders){
serviceEncoder.decode(encoding);
if(encoding.isModified()){
break;
}
}
if
(Tapestry.ASSET_SERVICE.equals(encoding.getParameterValue(ServiceConstants.SERVICE)))
{
servicer.service(request, response);
} else {
filterRequest(request, response, servicer);

Here's the hivemind config to inject the encoders:
construct

set-object property=serviceEncoders
value=service-property:tapestry.url.LinkFactory:serviceEncoders/
/construct
Thanks for catching my bug!

Unless I'm really screwing up, my check works with friendly URLs. I'm
using them. They way I understand the pipeline is that service
encoders take the original http request and do some preprocessing
before you end up with a WebRequest. Look at RequestCycleFactoryImpl
and AssetEncoder to see where this happens. The short version is
that the WebRequest should have a parameter set that identifies the
tapestry service being called.
What version of Tapestry? In 4.0.2, the pipeline calls the
WebRequestServicerFilter's before the RequestCycleFactory and the encoders have
done
their work. With friendly URLs, a typical path for an asset is something like:
/assets/031a6b16419c47ad157a817021baa2d6/class/path/file
This is still the form it is in when it hits the filter. getParameterNames()
returns an empty list, getParameterValue(ServiceConstants.SERVICE) returns null.
I'm currently using the following to recognize an asset request:
/assets.equals(request.getActivationPath())
You can verify this in the debugger by setting a breakpoint in both the filter
and
line 81 of RequestCycleFactoryImpl (where decodeParameters() is called), and
then
issuing a request for an asset. The filter will be reached first.
The problem with this too, is that it's not immediately obvious that something
is
wrong. The filter will still do its job, namely synchronizing the requests,
but it
will do it unnecessarily in the case of the asset requests.
If you're on a different version where things have changed, please disregard.

T5 - syntax for css background images?
Question: I've learned so far, to display an image ... you do something
like this:
SomePage.java
@Inject
@Path(./art_logo.png)
private Asset _someIcon;
and then SomePage.html you do
img src=${someIcon}/
BUT --- what's the syntax to use these in css EG: background images?
style type=text/css
!--
body {
background-color: #2D374A;
background-image: url(someBackground);
}
.MainTable {
background-color: #B5BFD2;
background-image: url(someBackground);
}

Hi,
this is an urgent and important issue for us. Can anybody help
with this? Howard?
As I wrote below: request.getServletPath() (or request.getPath())
already provides the decoded path.
a) Should request.getPath() provide the encoded path, or
b) should the additional decoding (in
PageRenderDispatcher.convertActivationContext) be skipped?
An excerpt from the servlet spec 2.4 p. 243:
getServletPath()
[...]
Returns: a String containing the name or path of the servlet being called,
as specified in the request URL, decoded, or an empty string if the servlet
used to process the request is matched using the “/*” pattern.
So why is additional decoding done?
Cheers,
Martin
Is anything else the problem? E.g. might the problem be caused
by commons URLCodec?
Thanx in advance,

I just stepped through the sources to see where the URI get's

convertActivationContext uses TapestryInternalUtils.urlDecode
which invokes URLCodec.decode. It seems that this causes the
problem, but I cannot say what exactly is the reason.
When I remove the invocation of TapestryInternalUtils.urlDecode
everything's fine...
Just to provide more info:
TapestryInternalUtils.urlDecode is invoked with the already decoded
context parameter, e.g. trüb for the urlencoded string tr%C3%BCb.
This parameter is read from request.getServletPath(), which is already
/search/trüb. So it tries to decode the already decoded string, which
then fails.
What is the problem here? Is it that request.getServletPath() provides
the already decoded string, or is the problem that the decoding is done
additionally by T5? Or what else?

I just tried that, but it does not solve the problem.
I have added a servlet filter that prints the requested uri to

The URIEncoding=UTF-8 does not change what's printed by the

Hi,
I have currently an encoding issue, but am not really sure what's
the reason for this.
I have an url that contains a url encoded german umlaut (ü) in UTF-8
and looks like the following:
http://localhost:8080/app/search/%C3%BCbel (the %C3%BC represents
the ü
in UTF-8, this url is created by
componentResources.createPageLink( search, new Object[]{ _query }
)
in the submit method of the search page)
Now, when I look in the onActivate(string) method, the string is not
übel but it's ?bel, both printed via logging as when I inspect
the
variable during debugging.
AFAICS the created url from the page link is correct in terms of
utf-8
encoding, but the parsed query string seems to be wrong, as it
contains
only the ?...
We have the following in our AppModule:
public void contributeRequestHandler(
OrderedConfigurationRequestFilter configuration,
@InjectService(TimingFilter)
final RequestFilter filter, @InjectService(Utf8Filter)
final RequestFilter utf8Filter ) {
configuration.add( Timing, filter );
Re: Help with handling exceptions while using Hibernate's open-session-in-view pattern in Tapestry
In my case, I'm using Spring's transaction management code to inject, via AOP, transaction semantics around service method calls. This means that my transaction commits when the service method (called from the listener, almost always) returns, so I can catch any exceptions before I even start rendering a response. In the vast majority of cases, if I get an error, I'm going to show an error page, so accessing objects that may cause lazy loading after the exception and rollback really isn't a problem, but I will say that in the few instances where it does occur, it doesn't appear to be a problem, precisely because anything involving lazy loading while rendering the view is guaranteed to be a read-only operation. So in our case, we don't have to explicitly handle a transaction manager, cause Spring is automatically injecting the start and commit of each transaction, as appropriate, and that is all defined in a config file rather than in code. There's almost certainly a way to use the classes provided by spring to do that work from within hiveming without actually using the spring aplpication context itself, if you don't want to eal with yet another IoC container\, and the mechanism works really well, allowing your application code to be completely independent of transaction semantics. To the listener method that makes the service call, it just looks like an exception was thrown in the service call if the transaction commit fails, and you can handle that case from within the listener pretty trivially. --sam - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

So, Spring's transaction management does in fact start a second transaction on the same session, even after an exception has been thrown, and you haven't seen an issue from this? I think I'm going to go this route too, and only worry about it if a problem comes up. If it does, I'll just make sure to eager fetch everything I might need on a listener method that might throw an expected exception, before the first transaction is committed, and then I'll just close the session rather that start a second transaction. So in our case, we don't have to explicitly handle a transaction manager, cause Spring is automatically injecting the start and commit of each transaction, as appropriate, and that is all defined in a config file rather than in code. That's very cool. At this point in time the explicit calls to manage the transactions aren't bothering me, although I will probably refactor them out in the future. I haven't gotten into AOP just yet and I'm not ready to introduce another complication, but it's definitely on my to-do list.

Re: dynamic component injection
Hi Guys,
I don't know if this is what are you looking for but here is how we
handle our dynamic components at Trails.
First we have a page which contains what we call editors (our
dynamic components):
http://svn.codehaus.org/trails/trunk/trails/modules/trails-core/src/main/resources/org/trails/page/Editors.html
http://svn.codehaus.org/trails/trunk/trails/modules/trails-core/src/main/resources/org/trails/page/Editors.page
They are all wrapped by @Blocks.
Then we have a map where the key is an ongl expression we use to
evaluate if that is right component for render a property, and the
value is a ComponentAddress. The map definition is in our sping
configuration file.
Here is an example of one entry:
entry
key
valuestring and !large and !identifier/value
/key
bean class=org.apache.tapestry.util.ComponentAddress
constructor-arg index=0
valuetrails:Editors/value !-- it refers to Editors
page --
/constructor-arg
constructor-arg index=1
valuestringEditor/value
/constructor-arg
/bean
/entry
So stringEditor is the name of the block we are going to look for in
our Editors page.
Then wherever we need to render one of those blocks we do:
span jwcid=$content$
span jwcid=[EMAIL PROTECTED] block=ognl:block/
/span
and
public Block getBlock()
{
ComponentAddress componentAddress = get the ComponentAddress from the
map.
componentAddress.findComponent(getPage().getRequestCycle()); //activate it.
// set all the properties you need to set
return (Block) componentAddress;
}
That's all!
This is safe to use inside a For or Table or wherever you need to use it.
Of course an ognl expressions map is not a good fit for everyone, so
you can use whatever service you need to implement your logic as long
as it returns a ComponentAddress from the Editors page.
I hope this helps you.
Saluti.
Alejandro.

I think this problem is not just related to one page applications but
apply also to any page/component that depending un user actions must show
different enough content (unless one wants to go with EventListener and a
long ugly list of IF components...)

Re: T5 - syntax for css background images?
You can use expansions inside a style block, just as you can
elsewhere in an HTML template. However, you have to eliminate the
HTML comments when you do so, or the expansions will not be processed:
style type=text/css
body {
background-color: #2D374A;
background-image: url(${someBackground});
}
.MainTable {
background-color: #B5BFD2;
background-image: url(${someBackground});
