commit 8f1edfcf71e8f36cb5df3f41eb2dc5ebf89663f2 Author: Claus Ibsen <[email protected]> AuthorDate: Wed Jul 22 08:51:32 2026 +0200 CAMEL-24231: camel-file - Fix pollEnrich with dynamic fileName using exchange properties (#24994) GenericFileHelper.createDummy() copies headers and variables from the incoming exchange but missed exchange properties. When pollEnrich uses fileName=${exchangeProperty.xxx}, the expression evaluates to null on the dummy exchange, bypassing the filename filter. Also fixes variables copy that was incorrectly nested inside the hasHeaders() guard. Reported by Marcus Ionker on the Camel users mailing list.
