it does not help. It's the way it's meant to work, but it doesn't.
Somehow the ObjectModels in the parallel running JXTemplateGenerators 
affect each other and we have strange side affects on most of our request.


we are digging around, but no ideas any more how to fix it...

any help would be appreciated.

Re: multithreaded Content Aggregator migration from 2.1 to 2.2

hi,

we found the problem in DefaultIncludeCacheManager and fixed it. I just 
submitted a patch together with some more information on the problem.


see:
https://issues.apache.org/jira/browse/COCOON-2216

thanks for your help.

I don't know if CocoonRunnable mentioned by Grek is another point for 
potential changes.

Hello,

bug in cocoon 2.2 .. its a very crucial issue for us.. we cant upgrade 
to 2.2  unless we  some how solve or find a work around for this issue ..


we have multithreaded Content Aggregator which is based on the 
CIncludeTransformer and it also implements 
CacheableProcessingComponent for caching .. it used to work fine for 
cocoon 2.1.x but with cocoon 2.2 it gives strange error .. it is 
actually a generator and it gives error in the generate method ..


the code where it gives error

// generate...
  for (Part part : this.parts) {
  if (this.manager.hasService(IncludeCacheManager.ROLE)) {
  part.uri = this.cacheManager.load(part.uri, 
this.cachingSession);

  } else {
  this.getLogger().error(
  "The ContentAggregator: aggregator cannot 
find the IncludeCacheManager");

  }
  }

  // aggregate...
  StreamPipe streamPipe = new StreamPipe(this.contentHandler);

part.stripRootElement);

  try {
  System.out.println("ParallelContentAgg.part.uri:" + 
part.uri);
  this.cacheManager.stream(part.uri, 
this.cachingSession, streamPipe);

  } finally {
  streamPipe.lastElement(part.element);
  }
  }

it gives the following error

What do you think?


hmm, just tried to solve that problem and found that in 
IncludeTransformer it works with threading and parallel processing. Only 
for the DefaultIncludeCacheManager we are using in our replacement for 
the aggregator to do parallel aggregation it is broken since version 2.2.


So I decided to patch the DefaultIncludeCacheManager to work in the same 
way as the IncludeTransformer does, by setting up the child threads with 
the same context/environment:


  // Setup this thread's environment
  RequestContextHolder.setRequestAttributes(
this.session.getRequestAttributes());
  EnvironmentHelper.enterProcessor(this.session.getProcessor(),
this.session.getEnvironment());

I'll test this out, and if it work's I send in the patch.

Re: a new cocoon logo?

[Christoph Gaffga (triplemind.com)]

> I've always wondered why the logo isn't a cocoon?

that's exactly what I liked about the new logo (Frédéric's). The
arragement of the letters let it look like a cocoon (at least a bit).

Perheps having a combination of the old cocoon 'logo' and a little
cocoon makes it easier to remember (A cocoon with a feather perhaps).
At the moment it's not much a logo, it's just a text.

Thanks, for me this is the closest to our "brand image", I like it!
I'd only lower the "powered by" text so that the bottom of the letters 
intersects with the box, and change the color of the letters to white 
where they intersect.

Do you have it in vector format? I think we need to create a big and a 
small version.

Then, we can maybe vote for an "official" version of this logo to 
recommend to our users, I suggest yours in two sizes, and Stefano's, so 
that people can choose a dark or light color depending on their site's 
look.

It's a little dirty I think. Perheaps a border in the same style as the

I'm thinking of something simple based on the logo

Note that this vector logo is stored in Illustrator format as

Christoph,
Just so that you know where I18nTransformer is (or supposed to be, or can be)
moving...
I18nT should have most of catalogue handling code removed, and should not have
any catalogue configuration information beside simply specifying the ID of
catalogue set it wants to work with:
  
Real configuration of the catalogues should happen within i18n bundle component,
probably as:
  

  
  
  
context://samples/i18n/translations/tiered
context://samples/i18n/translations
  


  ...

  
This way, catalogue handling part and actual catalogue usage are nicely
separated into two independent components (and you can easily overide one of
them without touching another)

exactly that was my intention. So: Between ... there ist only
a string, the Class is not introspected.
And I need the class-property only in class derived from Throwable, not for
all classes.

For my usecase it would work if there is a switch, in the
IntrospectionConfiguration for example, where I can put the output of
class-property on/off. Then I would turn it on for all and add sumething
like  to my dot-betwixt files.

But it would be nicer and more flexible if everybody could plug in his
custom strategy. A defaults strategy available: with-all-class-properites
and without-all-class-properties.

Another thing is, that I need the cause of the exception, I handled that
with the patch.

so, you saw, its realy a simple case, class-properties in all class
extending Throwable.

sure. And thank you a lot for having a look at this. I would code it myself
and send a patch, if I could, but I'm not so into the betwixt code. There is
a lot of deprecated code, and this not yet finished (?) change of the mapper
for simple/complex types.
