Re: [rules-users] accessing session clock from accumulation function or rule body?

You can assign the session clock to a global and access it from LHS conditions and inline accumulate functions. However, be aware that the value obtained from the session clock during LHS evaluations is anything between one WM operation and rule evaluation starts and another WM operation and the

It should be working in 5.5.0.beta1. 5.4.0.Final is what we released. I would not recommend using 5.4.0.beta1 as it is pre-release and some of it's internals could have changed for 5.4.0.Final (and later). Consequentially, and I believer other community members have been caught out this way,

Re: [rules-users] How to put Power in Formula box of THEN ?

The THEN part is either (depending upon the rule's dialect) a Java or MVEL code block. Java defines the ^ operators as a bitwise exclusive or. I suspect you should probably use Math.pow. Math is in the java.lang package so you shouldn't need to explicitly import. With kind regards, Mike On 24
