------------------------------

> -------------------------------------------------------------
>
> Key: WW-3843
> URL: https://issues.apache.org/jira/browse/WW-3843
> Project: Struts 2
> Issue Type: Bug
> Components: XML Configuration
> Affects Versions: 2.3.4
> Reporter: Pierre TEMPLIER
> Assignee: Lukasz Lenart
> Fix For: 2.3.5
>
>
> according to the docs one can override default
> typeconverters (cf:
> http://struts.apache.org/2.3.4/xwork-core/apidocs/com/opensymphony/xwork2/conversion/impl/XWorkBasicConverter.html
> )
> == Quote from the docs
> As from version 2.3.2 you can override default converters by
> implementting TypeConverter interface and specifying beans in
> struts.xml as follow: <bean
> type="com.opensymphony.xwork2.conversion.TypeConverter"
> name="collection" class="com.application.MyCollectionConverter"
> scope="singleton"/>
> I tried with that approach by creating a new TypeConverter (roughly
> copied from com.opensymphony.xwork2.conversion.impl.NumberConverter)
> adding the following line in struts.xml right after the <struts> tag
> <bean type="com.opensymphony.xwork2.conversion.TypeConverter"
> name="number" class="com.company.app.NumberConverter"
> scope="singleton"/>
> but the webapp failed to start with the following error.
> Caused by: Bean type interface
> com.opensymphony.xwork2.conversion.TypeConverter with the name number
> has already been loaded by [unknown location] - bean -
> file:/D:/dev/tomcat/webapps/blank/WEB-INF/classes/struts.xml:10:132
> at com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.register(XmlConfigurationProvider.java:227)
