[rules-users] MVEL modify block

Hello, trying as hard as I can, I am not able to do method calls within MVEL modify block, as I can do with Java block. For example: modify($p) { addDescription("aaa") } This works in Java, but not in MVEL. I was not able to find out how to call methods (not set properties, which works quite well). Any ideas what am I doing wrong? Does MVEL support method calls within modify block at all? If not, how can I safely call a method, that modifies fact attributes from MVEL? (I am not using shadow facts). Thanks, Juraj.
