This doesn't work since a method is invoked on the SettingsService in the contribution and the exception is thrown when realizing the service. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Tapestry-5-3-makes-it-impossible-to-load-symbols-from-DB-TAP5-1823-tp5719752p5719889.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

As suggested in the Jira, your SettingsService could @Inject ObjectLocator instead of the hibernate session. It could then lazily call ObjectLocator.getService(Session.class) to get the hibernate session. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Tapestry-5-3-makes-it-impossible-to-load-symbols-from-DB-TAP5-1823-tp5719752p5719763.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Tapestry > 5.3 makes it impossible to load symbols from DB (TAP5-1823)
Assuming the SettingsService resides in the same module, try this:
public static void contributeApplicationDefaults(MappedConfiguration
configuration, @Local SettingsService settings) {
settings.getString(UISymbolConstants.SUPPORTED_LOCALES, "de,en"));
}
the @Local annotation tells T5 not to look elsewhere for the service definition.

Tapestry > 5.3 makes it impossible to load symbols from DB (TAP5-1823)
We need to change some Tapestry symbols based on values from the database,
e.g. the SUPPORTED_LOCALES. We have a SettingsService that reads the values
- this service uses Hibernate, so it needs Tapestry IoC to be configured.
We use something like this to add the symbol:
public static void contributeApplicationDefaults(MappedConfiguration configuration, SettingsService settings) {
configuration.add(SymbolConstants.SUPPORTED_LOCALES,
settings.getString(UISymbolConstants.SUPPORTED_LOCALES, "de,en"));
}
This worked fine in Tapestry 5.2.x - now we upgraded to 5.3.x and we get an
ERROR during IoC initialization: "Construction of service 'ServiceOverride'
has failed due to recursion".
The reason behind this is the new TapestryModule#productionModeOverrides -
this method makes ServiceOverride dependent on symbols (hence SymbolSource).
We also tried another approach with contributing to SymbolSource:
@Contribute(SymbolSource.class)
public static void
addSettingsSymbolSource(OrderedConfiguration configuration,
final SettingsService settings) {
configuration.add("settings", new SymbolProvider()
{
public String valueForSymbol(String symbolName)
{
return settings.getString(symbolName, null);
}
}, "after:*");
}
with the same result.
There was already a bug filed (closed without solution):
https://issues.apache.org/jira/browse/TAP5-1823
Has anyone an idea how to solve this problem?
