String trim function in an GMF Audit environment [message #200012]

Hi,
I am trying to write Audits in a EMF/GMF context and looking for a
function to trim leading blanks from a String. Is there such a function
available?
I tried to work with def: but could not get it to run in my environment.
Even the most simple version "def: trim(s:String): String = s" did
produce an error saying Invalid OCL. Can you pls tell me what I am doing
wrong here.

Hello Walter,

You can not use "def" in GMF OCL AFAIK.
So, AFAIK to plug in "trim" function into the OCL you have to extend existing
set of OCL operations with additional set of operations (unfortunately I
do not know how to achieve it).
In addition you should be able to use java-based audits in GMF.
