Hi everyone, we found a problem in the post-processing of the (S)FTP component:
When the last processor of a route sets a outMessage, the post processing is not working. I created following reproducer: https://github.com/mash-sap/camelFTP The evaluation of the expressions (i.e. file:onlyname) is looking in the inMessage of the exchange to evaluate the filename (link<https://github.com/apache/camel/blob/main/core/camel-core-languages/src/main/java/org/apache/camel/language/simple/SimpleExpressionBuilder.java#L259>). However, the properties of the files may get bound to the outMessage if there is one (link<https://github.com/apache/camel/blob/camel-2.24.x/camel-core/src/main/java/org/apache/camel/component/file/GenericFile.java#L134>). Therefore the evaluation is not working as expected. I'm not too familiar with the code, but one possible solution (for post-processing) could be, to always bind the file-properties to the in message. But maybe this is not valid for other use-cases and therefore parameterization is required: Link<https://github.com/apache/camel/blob/camel-2.24.x/camel-core/src/main/java/org/apache/camel/component/file/GenericFile.java#L134> What do you think? Best regards, Manuel
