Description

When using a NotCachablePersistenceManager the following steps occur when changing .config file values:

 

1. ConfigInstaller.setConfig gets called.
2. Configuration gets retrieved from ConfigInstaller.getConfiguration method
3. getConfigurationAdmin().listConfigurations(filter) returns a new configuration each time because NotCacheablePersitenceManger is used.
4. Changes are performed in the new Configuration.
5. ConfigInstaller.doConfigurationEvent gets called back and retrieves configuration from configurationAdmin.
6. ConfigurationAdmin.getConfiguration retrieves cached value (hasn't been updated in step 4 because a new differente configuration was returned)
7. config file gets updated with cached values
