Mark Payne commented on NIFI-8666:
----------------------------------

Unfortunately I cannot seem to get Jira to display the description properly as the curly braces appear to cause it trouble. The intent there is not to have all of the newly within but to be more of the syntax:
DOLLAR OPEN_CURLY POUND {MyParameter}:toUpper() CLOSE_CURLY...

> Parameter names are allowed to have spaces in them, but any parameter with a space cannot be referenced from within Expression Language. For example, we cannot use:
> ${#{My Parameter}:toUpper()} or ${ #{'My Parameter'}:toUpper()}
> We should be able to reference the parameter using the single ticks in order to quote the parameter name.
