Use of Injection to provide Locale instances to components breaks when multiple
Locales are configured as Spring Beans in AppContext
------------------------------------------------------------------------------------------------------------------------------------
Key: TAP5-892
URL: https://issues.apache.org/jira/browse/TAP5-892
Project: Tapestry 5
Issue Type: Bug
Components: tapestry-spring
Affects Versions: 5.1.0.5
Reporter: Dave Greggory
Certain components such as Select have java.util.Locale injected into it. With
tapestry-spring-5.1.0.5, this creates a problem if you have Locale beans
configured in your Spring application Context (externally maintained with
tapestry.use-external-spring-context) as below.
<bean id="locale_US" class="java.util.Locale"><constructor-arg index="0"
value="en" /><constructor-arg index="1" value="US" /></bean>
<bean id="locale_UK" class="java.util.Locale"><constructor-arg index="0"
value="en" /><constructor-arg index="1" value="GB" /></bean>
This worked fine in Tapestry 5.0.18, but became a problem in 5.1. Currently, I
managed to get 5.1.0.5 of Tapestry running with tapestry-spring-5.0.18, but
this problem persists in tapestry-spring-5.1.0.5
Shouldn't tapestry be looking at the request to see which Locale it is for? Why
is it going into Spring's application context?
