Re: RequireJS Shim and JavaScriptModuleConfiguration
Nope. Doesn't work. I have my javascript files in the project under
resources resources/META-INF/modules/ol/ol.js
Does it map the META-INF/modules to a virtual resource? In your code I'm as
suing there is a folder under META-INF called assets/js?
If I use @Path(/META-INF/modules/ol/ol.js) corresponding to my folder
structure it fails with the error below:
Unable to locate asset 'classpath:modules.gz/modules/ol/ol.js' (the file
does not exist).
In the deployed file, it seems all javascript files are gzipped under
context-root/modules.gz And thats where its loading all the javascript from.

Hi,

Re: RequireJS Shim and JavaScriptModuleConfiguration
ol.js is not a module, it's an asset. That's why you're shimming it. So instead
of putting it in resources/META-INF/modules/, try putting it in
resources/META-INF/assets/js/.

Re: RequireJS Shim and JavaScriptModuleConfiguration

If you put actual modules in resources/META-INF/modules/, then they work fine.
Put non-modules in resources/META-INF/assets/ and make them available as

Re: IoC / Multiple Implementations
I don't think there's anything stopping you from binding a List as a
service.
Since list is a common class, you will probably want to use marker
annotations or @InjectService to disambiguate.
Both approaches are discussed here:
http://tapestry.apache.org/defining-tapestry-ioc-services.html

Well, the scenario is a simple service-interface that returns a JSON
array to configure a Javascript component. And depending on the input,
the content of the JSON array looks different, that's why there are
multiple implementations. Usually we iterate over the implementations
and take the first result that is not null - and I just noticed that's
exactly what the ChainBuilder does! It hides quite a bunch and does
'magic' :/ but I'll give it a try. I think Lances pointer to the
OrderedConfiguration looks quite useful, too and is basically the key
- I'll see what plays out best.
However, with the given options it's a little more overhead to
hand-craft the implementations to build the configuration but this
should be do-able. Though think it would be more intuitive to just
have the List injected from whatever is registered with the Binder.

public class FooProviderImpl implements FooProvider {

}
Then you can @Contribute to the FooProvider to add to the list and
@Inject
the FooProvider wherever you need the list.

empty. Does anyone have a hint where to look here? Maybe I need to
register that list explicitly.
Tapestry-IoC doesn't support that, at least not yet. What's your
scenario?
Usually, when we need more than one implementation of a given
interface, we
create a pipeline (
http://tapestry.apache.org/pipelinebuilder-service.html)
or chain (http://tapestry.apache.org/chainbuilder-service.html) to
consolidate all these implementations as a single service. Or you can
create a service that receives these service implementations as its
distributed configuration and acts as a locator for it.

Re: WebSocket for tapestry
1. No errors in JavaScript
2. I'm using 5.3.6
3. I did, all work ok and do not lose their ability to do ajax calls.
The problem is as you guessed it. I changed the javascript like so and it
works perfectly:
tapestry-atmosphere.js

if (pushTarget.update == 'PREPEND') {
var insertion = new Hash();
insertion.set('top', content);
element.insert(insertion.toJSON());

I think this function needs to be smarter and do a dom based element

I tried to avoid using prototype or jquery so it was agnostic so just did a
quick and dirty string concat. I can see this would cause the problem.

after I put in the configuration. These eventLinks are supposed to be
ajax.
The eventLink rendered with the last block correctly calls the page via
ajax, however all other eventLinks in blocks already displayed no longer
make ajax calls. It looks as if they get deregistered somehow from the
Tapestry onClick handler that makes ajax calls.

Redirecting to a page from a MethodAdvice implementation

annotated with a custom @ExceptionDisplay annotation. Everything works as
expected, but I would like to redirect to a page. I'm using
PageRenderLinkSource and Response to do that. I inject them in the same way I
usually inject them into pages, but in this case it does not work, because the
PageRenderLinkSource and Response instances are both null. I imagine that's
because they should be only injected into pages or components, so I'm wondering
if / how is it possible to redirect to a page from a MethodAdvice. Thanks in

As a simple rule, if you instantiated the object yourself, @Inject won't
work.
See here:
private final MethodAdvice advice = new MethodAdvice() ...
You've used new so it's not under tapestry's control.

Re: Error in BeginRender[...]: Parameter 'translate' of component .. is bound to null. This parameter is not allowed to be null.
Thanks, Thiago. Resolved. Generally, seems like this problem is caused by
botched getter method (my case) or not using translate/null handler in
presentation layer.
I got the hint from your question below and also other solutions to the
issue of translate attribute in textfield (to render dates etc). Turns
out programmer had overloaded the getter method in this case.
Specifically, the entity class, Project, had a isDetails() as well as
getDetails() method within the entity class. No clue why someone
would do that. However, this made the detail property ambiguous to the
textfield renderer and it was looking to translate boolean which was
actually null in the database - disaster I just changed the
spelling of the method from isDetails() to isDetailed() and took care of the
cascading effects. The whole application is working fine now.

Tapestry itself doesn't look at database tables for defining validation
constraints at all.
I have been looking at the bulletin boards, stack overflow and seems like a
known issue...
Any links to other people having the same issue?
By the way, you haven't posted the full stack trace, which is very important to
figure out what's happening. Nor you posted the full error message from
Tapestry. You probably didn't any answers because of that. Maybe the error is
from another component instance and you're looking at the wrong place. The
Parameter 'translate' of ... is bound to null error message is almost always
related to trying to edit a non-String property with TextField or TextArea.
That's why I'm thinking you're looking at the wrong component.
t:textArea t:id=details t:validate=maxlength=255 rows=3 cols=90
value=entity.details /
@Entity @Indexed
public class Project
{
@Id @GeneratedValue @DocumentId
@NonVisual
private Long id;
@Field
private String details=;
Questions: 1. In text area should there be another attribute? I tried
nulls=default
No. Does it have public getter and setter methods?
2. In entity class, Should there be some type other decorator besides @Field
(the @Parameter is not allowed to experiment with acceptNull=true)
@Field is an annotation, not a decorator. @Parameter can only be used in
Tapestry components and mixins, and your entity class isn't either. @Field
seems to be from Lucene or Hibernate Search and it's ignored by Tapestry itself.
