Hi,
I'm running into a problem in which the getList operation returns an
empty List if and when the underlying configuration file is updated (I
am leveraging the FileChangedReloadingStrategy). I am using Commons
Configuration 1.4 with the DefaultConfigurationBuilder in conjunction
with the XPathExpressionEngine. Please note, other operations, getString
for example, work fine.
Here's an excerpt from my configuration.xml file ...
<xml fileName="retroplan-config.xml" config-name="retroplan"
config-optional="true" throwExceptionOnMissing="false">
<reloadingStrategy refreshDelay="1000"
config-class="org.apache.commons.configuration.reloading.FileChangedRelo
adingStrategy"/>
</xml>
So, with that said, are there known issues with the 1.4 implementation
of the FileChangedReloadingStrategy and/or the getList operation that
would explain this behavior?
Thanks, Tom
There are no open issues with getList() and FileChangedReloadingStrategy
I am aware of.
At first I would like to ask you to update to Commons Configuration 1.5,
which has been released recently. Don't know whether this will help, but
just in case.
If the problem persists, I need some more information to reproduce it:
- A code fragment demonstrating how you access the configuration.
- A fragment of the configuration file with the properties you try to
access.
- In which way is the configuration file changed on disk? Was the key
you try to access just added?
- What happens if you pass the key you use for getList() into
getString() or some other method? (In this case the first element of the
list should be returned.)
- Does getList() work after getString() was called?
