--------------------------------------------------------------------
I attached the patch containing the failing TestCase. Note that the problem I
initially tried to highlight is showing by the assert {{Attribute Override
Failed (4)}}, but while writing the test, I also obtained a fail for the assert
{{Attribute not passed (19)[true]}}. Thank for your help.

> [Digester] Problem when adding multiple FactoryCreateRule for the same pattern

> Key: DIGESTER-176
> URL: https://issues.apache.org/jira/browse/DIGESTER-176
> Project: Commons Digester
> Issue Type: Bug
> Affects Versions: 3.2
> Environment: Operating System : Windows 7 x32 bits
> Reporter: BRABANT Benjamin
> Priority: Minor
> Attachments: OverrideFactoryCreateTestCase.patch
>
>
> Hello,
> I actually use digester API in a project in which I have to initialize
> components of a system according to an XML configuration. The complete
> ClassName of the factories in charge of loading the associated components is
> specified in the configuration file (hereinbelow a simplified example). Thus,
> the loader class in charge of loading components, read the XML file and,
> thanks to the {{overriddenByAttribute(String attributeName)}} function
> provided by the {{FactoryCreateBuilder}} class, execute the right factory
> method specified by the XML "factory" attribute.
> A problem appeared when I try to load several components of the same type (=>
> same XML pattern) which are initialized from different factories (below the
> sample to illustrate the description !).
> *XML Config File :*
> {code:xml}
> <loader>
> <components>
> <collectors>
> <collector id="collector" class="foo.bar.DefaultCollector"
> factory="foo.bar.DefaultCollectorFactory" /> <!-- The first collector
> component to load -->
> <collector id="command" class="foo.bar.CommandCollector"
> factory="foo.bar.CommandCollectorFactory" /> <!-- The second collector
> component to load -->
> </collectors>
> <analyzers>
> <analyzer id="analyzer" class="foo.baz.DefaultAnalyzer"
> factory="foo.baz.DefaultAnalyzerFactory" /> <!-- The only analyzer component
> to load -->
> </analyzers>
> </components>
> </loader>
> {code}
> *AbstractRulesModule Implementation :*
> {code:title=LoaderConfigurationModule.java|borderStyle=solid}
> package foo;
> import org.apache.commons.digester3.binder.AbstractRulesModule;
> public class LoaderConfigurationModule extends AbstractRulesModule {
>
> \@Override
> protected void configure() \{
> forPattern("loader/components/collectors/collector")
>
> .factoryCreate().ofType(AbstractCollectorFactory.class).overriddenByAttribute("factory")
> .setNext("addCollector");
> forPattern("loader/components/analyzers/analyzer")
>
> .factoryCreate().ofType(AbstractAnalyzerFactory.class).overriddenByAttribute("factory")
> .setNext("addAnalyzer");
> \}
> }
> {code}
> When I execute the Digester.parse() method (after passing on the
> LoaderConfigurationModule to the DigesterLoader), I obtain the result below :
> {noformat}
> 2013-06-10 [main] INFO - Loading Collector [class
> foo.bar.DefaultCollector]...
> 2013-06-10 [main] INFO - Loading Collector [class
> foo.bar.DefaultCollector]...
> 2013-06-10 [main] INFO - Loading Analyzer [class foo.baz.DefaultAnalyzer]...
> {noformat}
> In fact, when having the same pattern (here
> _loader/components/collectors/collector_) for multiple creation factories,
> the digester only use the first instance for the pattern (in this case
> foo.bar.DefaultCollectorFactory]. We realize that the Analyzer which is
> associated with another pattern is correctly initialized.
> I hope being clear in my explanation, thus I would like you (please :) ) to
> explain me if I am doing a mistake in my code or if it's really a bug in the
> digester and if you have an idea to solve that. I am trying to find a
> solution too, but being new in this project, it is not very easy for me. I
> will post my find in case of success in my search !
> Thanks for reading and sorry for my bad english !
> EDIT [17/06/2013] : I attached the patch adding the failing TestCase
