List files by regex - no answer

The create_temporary_directory beanshell creates a temporary directory and outputs the path to that directory.

The populate_directory beanshell creates several files within the temporary directory.

Once the directory has been populated, it is examined by the List_files_by_regex service. Since no files match the regular expression 'x.*' i.e. no files have a name that starts with 'x', an empty list is output.
