Parsing comma separated list [message #1734671]

I am looking to be able to parse a list of values, like this:

using ( file1.xml , file2.xml , file3.properties )

The rule I have for this is:

MyFilesList:
	'using'  "(" configFiles = Files ")" ;
/*A list of comma separated files ending with xml, properties) */
Files:
	files+=ConfigFile ("," ConfigFile)*;
ConfigFile:
	file=FileName;
FileName:
	(ID | INT) "." ("xml" | "properties");

Issue is with the definition for ConfigFile. I am getting "Cannot change type twice within a rule" Error.
Any idea how to simplify this rule ?

Thank you

This is exactly what I needed.
I didn't know that you can use the add assignment multiple times !

Thank you Christian.
