hi i thing using a string could cause some problems better use your own object named like "Mock" containing a string with setter and getter in the java code assert the object in working memory with MemoryManager.getWorkingMemory().setGlobal("mock", mock); in the rule file don't forget to import your Mock and global Mock mock in the when $mock : Mock( ) and other conditions in the then statement $mock.setMyString("hello world"); after the rule fire the value must have been changed ... hope it's clear enough friendly JLL Joj wrote: > > Hi, > > In the document, its written that "They are typically used to return > data" under globals section.
