[jira] Commented: (CONFIGURATION-214) Adding an integer and getting
it as a long causes an exception
[ http://issues.apache.org/jira/browse/CONFIGURATION-214?page=comments#action_12413585 ]
Oliver Heger commented on CONFIGURATION-214:
--------------------------------------------
I agree with you that this is a bug. Coversions between the Number types should be possible. Will have al look.

> Key: CONFIGURATION-214
> URL: http://issues.apache.org/jira/browse/CONFIGURATION-214
> Project: Commons Configuration
> Type: Bug
> Versions: 1.2 Final
> Environment: Linux, java 1.5
> Reporter: Sebastiano Vigna
> Priority: Minor
>
> Try this in a BeanShell:
> bsh % p = new org.apache.commons.configuration.PropertiesConfiguration();
> bsh % p.setProperty("foo", 6);
> bsh % p.getLong("foo");
> // Error: // Uncaught Exception: Method Invocation p.getLong : at Line: 3 : in file: <unknown file> : p .getLong ( "foo" )
> Target exception: org.apache.commons.configuration.ConversionException: 'foo' doesn't map to a Long object
> org.apache.commons.configuration.ConversionException: 'foo' doesn't map to a Long object
> at org.apache.commons.configuration.AbstractConfiguration.getLong(AbstractConfiguration.java:667)
> The problem is that when an object in a property is not a Long, the only attempt of PropertyConverter.toLong() is that of treating it as a string. It could try to convert it to a Number first and then try to convert it to a long. It is a very confusing behaviour, because if you save and reload the properties everything works fine (as now the integer is a string).
