Please be more specfic. If your field is called "foo", then
should have a method in the class representing
your fact, such as:
boolean getFoo(){
return <condition> ? ! (<expression>)
: <expression>;
}
Basically, <condition> could be a global parameter (public static
final)
or a static or regular method call. <expression> could depend on
other
attribute values, and so on.
You can then write your CEs with a test such as
foo == true
But I think this is closely related with that other question you
have posted.

Well the thing is, it's not just one condition - it's the combination of
all
my rule's conditions.
And my rules have about 7 conditions, none of which are mandatory.
And that is actually the source of all my problems: that the conditions
are
optional.
If I set up a few logical relationships, there is nothing specific I am
testing on, which gives a single expression I can test in a function. In
procedural programming, I check each of the 7 conditions optionally, and
then I apply my ternary operator to the final result. But here I
can't do
that, because the condition is made up of all the little conditions that
may
or may not be applicable.
PS.
Ok, so I see from the other thread that a rule template is meant to place
whatever text you give it, like a text pre-processor. I'll see if
that is
correct, thanks. I thought it might not be, because if you provide
a blank
cell, it deletes your entire condition, instead of providing a ""
or a null,
like you'd expect from a text pre-processor.

I implemented this, so I hope I still know what I did. :-)

The idea of the interface for generating rules from object collection
is to avoid the constraints of spreadsheet translation.

Tested it and this is a bug.
I made a Jira for it so you can follow it.

Do you use "global" in your rules? This would be the "declaration"
of an
entry point.
Also, KnowledgeSessionConfiguration should be passed to the method call
creating a session, which I don't see in your code.

Hi Malinda,
rule "myrule"
when
//some condition
then
insert(new Object());
// or
Variable var = new Variable();
insert(var);
end
