See the red box on the page about pollEnrich - its not dynamic.
There is a JIRA ticket to improve this in the future (but its a bit
harder due API changes)
You can though use a java bean and use consumer template where you can
do dynamic.
Or if you dont need to move/delete the file or do any custom
aggregation strategy, then its much easier to just do a message
transformation and set the body type to java.io.File and the body
content as the file name.
<transform>
<simple resultType="java.io.File">${header.someName}</simple>
</transform>
