In Seam, you can load a message-bundle via EL, like (look at SEAM-Reference 16.3.2. Displaying labels):
Thats fine, you can even access the value of property-files in JAVA-Code:
@In private Map<String, String> messages;
Can I load/save (other) property-files (not only language-bundles) in the same manner?
