How? When I try something like this:

rule "AttributeChange EAttribute id"
    when
        diff: IDiff( operationType == OperationType.ADD, differenceType == DiffType.ATTRIBUTE, parameter=="id", !oldValue.equals(newValue) )
end

I get the following error:

Error: [12,0]: [ERR 102] Line 12:0 mismatched input 'end' in rule "AttributeChange EAttribute id"
Error: [0,0]: Parser returned a null Package


Also I get an error when I try to use something like this:

rule "AttributeChange EAttribute id"
    when
        diff: IDiff( operationType == OperationType.ADD, differenceType == DiffType.ATTRIBUTE, parameter=="id", !oldValue.equals(newValue) )
    then
end


Error: Rule Compilation error : [Rule name='ReferenceChange EClass add Attribute/Reference']


Can you give me an example?

Hello,

I have many rules, which have exactly the same "then" block. Is it possible
to leave the then cause empty?

Yes.
-W

I only need to know is if a rule was
activated or not and for this reason I'm using
WorkingMemoryConsoleLogger.activationCreated().
