> Attribute value cannot delimit to list
> --------------------------------------
>
> Key: CONFIGURATION-733
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-733
> Project: Commons Configuration
> Issue Type: Bug
> Affects Versions: 2.4
> Reporter: Hao Chen
> Priority: Major
>
> Given the following configuration XML:
> <configuration>
> <header>
> <result throwExceptionOnMissing="true">
> <listDelimiterHandler
> config-class="org.apache.commons.configuration2.convert.DefaultListDelimiterHandler">
> <config-constrarg config-value=","/>
> </listDelimiterHandler>
> </result>
> </header>
> <node type="test" types="a,b,c"/>
> </configuration>
> With the following test code:
> Parameters params = new Parameters();
> ReloadingFileBasedConfigurationBuilder<XMLConfiguration> builder
> = new
> ReloadingFileBasedConfigurationBuilder<XMLConfiguration>(XMLConfiguration.class);
>
> builder.configure(params.xml().setFile(file).setListDelimiterHandler(new
> DefaultListDelimiterHandler(',')));
> XMLConfiguration configuration = builder.getConfiguration();
> List<String> types = configuration.getList(String.class,
> "node[@types]");
> // result WRONG -- returns ["a,b,c"]
> org.junit.Assert.assertEquals(types.size(), 3);
> I just couldn't find any way to get the attribute value as a comma-delimited
> list...
> In general, the default behavior change for list delimiter is a big headache
> while we are trying to upgrade to commons-configuration2...
