t5: overriding URLEncoder
Hi,
I'd like to override the URLEncoder to allow '=' as part of URL, here is
what I did:
binder.bind(URLEncoder.class, URLEncoderImpl.class);
but I got this:
2009-03-17 23:58:13.215::WARN: failed app
ava.lang.RuntimeException: Service id 'URLEncoder' has already been defined
by org.apache.tapestry5.internal.services.URLEncoderImpl() (at
URLEncoderImpl.java:22) via
org.apache.tapestry5.services.TapestryModule.bind(ServiceBinder) (at
TapestryModule.java:150) and may not be redefined by
org.abx.myapp.t5.services.URLEncoderImpl() (at URLEncoderImpl.java:22) via
org.abx.myapp.t5.services.AppModule.bind(ServiceBinder) (at
AppModule.java:42). You should rename one of the service builder methods.

Do
binder.bind(URLEncoder.class, MyURLEncoderImpl.class).withId("MyUrlEncoder");
public static void contributeAliasOverrides(@InjectService("MyUrlEncoder") URLEncoder encoder,
Configuration<AliasContribution> configuration)
{
configuration.add(AliasContribution.create(URLEncoder.class, encoder);

Re: t5: overriding URLEncoder
Posted by Fernando Padilla <fe...@alum.mit.edu>.
oh. right. another option is to look up decoration.
So instead of whole-sale replacing it, you can "decorate" the default
service with your own logic. Pretty easy.

Re: t5: overriding URLEncoder
Posted by Robert Zeigler <ro...@scazdl.org>.
There are two services:
Alias
AliasOverrides.
Alias is intended for services that can be overridden. (ie, when there
might be multiple services implementing the same interface and you
want to specify, by default, which to use).
AliasOverrides is intended for when you want to override the default.
So, you should be contributing to AliasOverrides, really.
Your problem here is that your url encoder implementation apparently
has dependencies that rely on the alias service.
This is /really/ easy to hit, I've found, unfortunately.
If you're on 5.1, you could try the new "ServiceOverride" service;
that /might/ help you.
If you're providing your own URLEncoder implementation, then sometimes
"recursion problems" are helped by doing something like:
public static void contributeAliasOverrides(@Local URLEncoder encoder);
But YMMV.

Hi,
here is my code:
binder.bind(MyURLEncoderImpl.class, MyURLEncoderImpl.class);
public static void contributeAlias( MyURLEncoderImpl enc,
Configuration<AliasContribution> conf ) {
conf.add( AliasContribution.create( URLEncoder.class, enc ) );
}
but still get:
[ERROR] Registry Construction of service 'Alias' has failed due to

Re: t5: overriding URLEncoder
Posted by Fernando Padilla <fe...@alum.mit.edu>.
looks like I might have had another typo?
The function is "contributeAlias", not "contributeAliasOverrides". Not
sure if you have already caught that.
http://tapestry.apache.org/tapestry5/guide/alias.html
but aside from that. can you put up the exact code you have?

Re: t5: overriding URLEncoder
Posted by Angelo Chen <an...@yahoo.com.hk>.
Hi,
Thanks for the reply, I tried:
1. there is no AliasConfiguration, I replaced it with AliasContribution
2. got this error:
[ERROR] Registry Construction of service 'AliasOverrides' has failed due to
recursion: the service depends on itself in some way. Please check
org.apache.tapestry5.internal.services.AliasManagerImpl(Logger, Collection)
(at AliasManagerImpl.java:32) via
org.apache.tapestry5.services.TapestryModule.bind(ServiceBinder) (at
TapestryModule.java:150) for references to another service that is itself
dependent on service 'AliasOverrides'.
any idea?

Re: t5: overriding URLEncoder
Posted by Fernando Padilla <fe...@alum.mit.edu>.
Sadly, this feature is aliasing, not override. So technically, you
should not step on the toes of the original service at all..
1) So do not use "withId("URLEncoder")", since there is already a
service with that name. Try changing that to "URLEncoder2".
2) if you bind it to "URLEncoder.class", like you did, then anyone that
asks for a URLEncoder (@Inject URLEncoder enc), will fail, because
tapestry will see 2 possible matches. So i could bind it to your raw
class for now.
I think this code will work ( but untested ).
binder.bind( MyURLEncoderImpl.class, MyURLEncoderImpl.class );
public static void contributeAliasOverrides( MyURLEncoderImpl enc,
Configuration<AliasConfiguration<?>> conf ) {
conf.add( AliasConfiguration.create( URLEncoder.class, enc ) );
}

Re: t5: overriding URLEncoder
Posted by Angelo Chen <an...@yahoo.com.hk>.
Thanks, but can't make it work, here is my code, must be missing something:
binder.bind(URLEncoder.class,
MyURLEncoderImpl.class).withId("URLEncoder");
public static void contributeAliasOverrides(
@InjectService("URLEncoder") URLEncoder urlencoder,
Configuration<AliasContribution<?>> configuration) {
configuration.add(
AliasContribution.create(
URLEncoder.class, urlencoder));
}
