Changeset 25666 for main/trunk/gli/src/org/greenstone/gatherer/collection/BasicCollectionConfiguration.java

Message:

For image-e, the OpenDialog was displaying the Chinese collection display name and description (zh was the last language code in collectionConfig.xml for which name and description were defined). Now the code first looks for any meta specified for the gli lang annd if not, then for any meta specified for the default language (en), and if that's not there, the it finally falls back to using the value of the first language for which the metadata is specified.
