Re: [rules-users] using "From" keyword in the rule
I guess it depends on whether there is a static connect() method on the Database class
which returns a DatabaseConnection, which in turn has a method
getUserRisk(POC_CombineString), which returns an instance of the TestValue class.
On a side note, it's a very bad idea to put database calls in the LHS of your rules.
It invariably plays hell with performance. Although potentially it gives people like me a
job re-writing slow applications, as I was doing last year, so not everyone loses out. ;)

There is no reason why this should not compile.
I suspect that you have not posted the *accurate* text of the rule
where that error occurred. Does the snippet you've mailed
cause the same error?
