I found out the problem, or kind of. I have a contribution to the periodic
executor with an @Startup annotation, this contribution uses another
service which is build using @Autobuild. This last service has a
constructor which expects a Logger as parameter and this is what is
failing, something like:

@Startup
public static void scheduleTrigger(PeriodicExecutor executor,
   @Autobuild
   final CalendarioEventsTriggerer
triggerer) {

public CalendarioEventsTriggerer(..., Logger log) {

This is working perfectly in 5.3.

PerThread service unique?

2012-04-30 Thread Manuel Sugawara 
Hi all,

I have a service that is marked with @Scope(ScopeConstants.PERTHREAD). Can
I assume that there will be just *one* instance of this service per thread
or there may be multiple instances?. I was under the impression that this
service will be unique per thread but am facing a problem that might be
explained if there are multiple instances of it. Any pointers to the
documentation will be appreciated. My reading of
http://tapestry.apache.org/defining-tapestry-ioc-services.html suggests me
that there will be just one instance but wanted to be sure.

ApplicationStateManager throws an exception when an object is requested

2010-10-13 Thread Manuel Sugawara 
Hi all,

Using tapestry 5.2.1. I have a filter that serves resources to clients
(images, documents, etc). This filter uses an injected service to check if
the user has the required permission to download the resource, but this is
not working as expected. The authorization filter throws an exception when
the following line is executed (full stack trace below):

stateManager.getIfExists(Session.class);

where stateManager is an ApplicationStateManager instance. The filter is
build by the application module using:

public static void
contributeHttpServletRequestHandler(OrderedConfiguration
configuration, @Autobuild FileFilter fileFilter) {
configuration.add("FileFilter", fileFilter);
}


The stack trace is:

Oh well, I'm not alone ;-). Particulary because doing this by hand is too

That's exactly what makes it a good idea, in particular for the case
described below. Also this allows the application to easily interoperate.
Think all those sites that provides a GET interface to search that can be
easily integrated with browsers (ej, the search box in firefox).

Note the use case, is a search which will not change the database or
application state. I do agree with Lutz, there are cases where GET is much
more appropriate than POST. Not just because it makes more sense but also
because it gives you a bookmarkable URL. That being said, I just love
default redirect-after-post for those forms that *actually* modifies the
application state, just this is not the only use case.

Libarary "core" mapping not working in 5.2.0-SNAPSHOT

2010-06-02 Thread Manuel Sugawara 
Hi,

I have a library that uses the core mapping but a few days ago
this stopped working. Tapestry throws an exception saying "Package names for
library folder 'core' (mx.unam.xfc.escuela.t5, org.apache.tapestry5.corelib)
can not be reduced to a common base package (of at least two terms)." As
this was reported before but got no answer I will try again. Is this not
supported anymore?, Is this a bug?, Should I create a Jira issue?.

Forms and overlays

2010-05-20 Thread Manuel Sugawara 
Hi all,

I'm writing a form that has a select with an special option "other...". When
this option is selected another form is show in an overlay to allow the user
to provide the "other.." option info. I have solved this using two forms in
the same template one of them is hidden and is only show when the clients
select the other option. When this is done I sent the form using prototype's
request on the form and waiting for its JSON response, same that I use to
populate the new option. Everything is working more or less fine but I would
really love to hear you insights in this solution. Is this approach
correct?, Is there any better way to accomplish this?. Any library out there
that does this?.

Empty body?

2010-03-12 Thread Manuel Sugawara 
Hi

I'm working in a menu component, similar to the one in the howtos. The
menuItem template looks like:


  

  ${pageTitle}
  
${pageTitle}
  


  

  


however this template still renders an empty  if there is no body. I
would like to conditionally display the ul depending if there is a body or
not. Something like:


  

  


Now, I have solved this implementing the hasBody method like:

@Inject
private ComponentResources resources;

public boolean getHasBody() {
Block block = resources.getBody();
if ("".equals(block.toString())) {
return false;
}
return true;
}

This works but seems a bit flaky. Is there a better way to figure out if a
block is empty?

Hi all, I'm using tapestry 4.0 and have a service that what roughly
does is create a PDF file in the tmp dir if it does not exists. If the
file exists or after its creation the service returns its contents to
the client. Now I'm worried about synchronization issues in this

and creates one if none exists, but this will not work if multiple
instances of the service are concurrently running. So, can I safely
assume that there is only one instance of the service running?, I

service running, is Ok to synchronize on some global object? (global
