Hi Mike,
I couldn't bind a field because the click on the field doesn't work.
concretely, please see attached.
Thank you in advance,

Glad to be of assistance.
To bind a field, once the field has been added to the Fact type simply click on the field name.
With kind regards,
Mike

Hi Mike,
I’m a colleague of Matteo Cusmai, we would like to thank you for your suggestions. you have been very helpful.
Following your steps, I couldn't understand a point: how can I bind a field(for ex. RadiationObservation.location) to a variable?
specifically,
$obs : RadiationObservation(?$obsLocation : location? ) over window:length (1) from entry-point "lowLevelSensorStream"
Best regards,
Carolina Pellecchia

Think of a stateless knowledge session as being a statefull knowledge session, with the following adjustments:
A stateless knowledge session cannot be manipulated prior the start of the session.
A stateless knowledge session cannot be manipulated or queried after the end of the session.
A stateless session begins when you execute the fireallrules method.
A stateless session ends when the rule processing terminates. -- There is no pause, there is no restarting. The instant the rules stop firing, and return to your calling code, the knowledge session has been torn down.

Subject: [rules-users] Setting variables in a stateless session
hi folks, this is a simple question ,
i just want to understand how is it possible that a stateless session have a
setGlobal() method as it does not maintain a state. What's the point ?!
i also have some confusion between a "request scope" and a "stateless
session scope" i think it s the same..

Sure.
- Create "New Rule"
- Add a condition (green + near "WHEN")
- Select "From Entry Point"
- Type "lowLevelSensorStream" into TextBox
- Click on "click to add patterns..."
- Select your Fact Type (see * below)
- In "Over sliding window" ListBox select "Length"
- Type "1" into the TextBox next to "Length".
* OK, so this is possibly where you're having problems.
In order for a Fact Type to be used with CEP it needs to be annotated as an
Event. This is how this can be accomplished:-
*If you have a Declarative Model
*
- Open the Declarative Model
- Select the Fact Type that should be an Event
- Add an Annotation, name="role", key="value", value="event"
- Save
*If you have a POJO Model*
- Create a new Declarative Model
- Add a Fact Type that matches the name of that in your JAR
- Add an Annotation, name="role", key="value", value="event"
- Save
Annotating your POJO is covered in the Drools Expert User Guide. You are
just using Guvnor to achieve what is required.
With kind regards,
Mike

I have not yet determined how I want to implement my problem and was hoping
to get some feedback.
I am using drools to migrate the logic from my automated currency trading
infrastructure. Each currency pair, i.e. eurusd has around
200 attributes associated with it.
This includes range values (high, low, average) for multiple time periods,
volatility information, bid/ask updates etc.
Currently I have classes associated for each, so say for range:
class Range {
double high;
double low;
double avg;
}
Range europe = new Range(); //european trading hours
Range us = new Range(); //us trading hours
Questions:
1. I am wondering if I should not just create a map that lists every
attribute per pair as a key ("eurusd:range:europe:high")? So essentially
my drools session will have one fact, not counting the incoming quotes. I
see on the list that this was a problem before the mvel updates but that
was a while ago.
2. When an incoming quote might modify a value, what is the performance
difference between using a rule to change the value or making the changes
outside of the ksession and referencing the facthandler to modify? Is one
method considered 'cleaner'?
Thanks,
Bobby

What I am prototyping is part of the event processing (with or without
fusion). I want to use the rules created by the Guvnor to create the new
events. However, as you would understand, once the event has been created,
it should not be modified as it happened in the past.
So I am trying to avoid setters if possible.
