Indeed. Hence the JIRA.
Howard has mentioned the possibility of merging the two type
coercion systems.
That Would be great!
What I currently do to seamlessly use Entities across the framework
(activation / deactivation, parameters, RadioGroup / Radio:
- I have a service
public interface EntityCoercionConfigurator {
void configureEntityCoercions(ConfigurationCoercionTuple?, ?
configuration);
void configureEntityValueEncoders(MappedConfigurationClass,
ValueEncoderFactory configuration);
Which discovers all registered Entities (JPA, Hibernate).
It is then used in
public void contributeTypeCoercer(
@Inject EntityCoercionConfigurator configurator,
ConfigurationCoercionTuple configuration) {
configurator.configureEntityCoercions(configuration);
}
This gives me the String - Entity and Entity - String coercions I
need. So far so good!
What I don't like is that I also have to
public void contributeValueEncoderSource(
@Inject EntityCoercionConfigurator configurator,
MappedConfigurationClass, ValueEncoderFactory configuration) {
configurator.configureEntityValueEncoders(configuration);
}
Which currently instantates a ValueEncoderFactory that produces just
one ValueEncoder that routes all toClient() and toValue() calls to
the type coercer.
This is not that bad but I'd like to leave out the second step. :)
P.S. It might be good that such code finds it's place in tapestry-
hibernate. I'd be glad to contribute it if there is interest for that.
Cheers,
Ognen

This error looks familiar. Can you post some source? (I can't get to it myself for a couple of days though.)

Re: T5 Type to ValueEncoderFactory
Tapestry just supports a ValueEncoder for String and Enum. If you want
additional
encoders you have to implement them yourself:
class LongValueEncoder implements ValueEncoderLong
{
public String toClient(Long value)
{
return value == null ? : value.toString();
}
public Long toValue(String clientValue)
{
try
{
return new Long(clientValue);
}
catch (NumberFormatException e)
{
return null;
}
}
}
To use the encoder either add them to your AppModule:
public static void contributeValueEncoderSource(
MappedConfigurationClass, ValueEncoderFactory configuration)
{
configuration.add(Long.class, new
GenericValueEncoderFactoryLong(new LongValueEncoder()));
}
or add the encoder directly to your RadioGroup (or Select) components (see
http://tapestry.apache.org/tapestry5/tapestry-core/component-parameters.html)
See:
http://issues.apache.org/jira/browse/TAPESTRY-1598

Re: T5 Type to ValueEncoderFactory
Thanks for the info. I'll add that to my component. However, it seems
odd that a simple conversion from Long to String isn't built in. It
seems to me that such standard conversions should be part of the
framework.

T5 Type to ValueEncoderFactory
