Description

Janos Apro sent a message using the contact form at
http://catalogue.fiware.org/.

1. There is a bug with EPA derived event saving, sometimes we get different
settings after reloading the page - I noticed that while creating multiple
derived events inside one EPA.
2. I have the following definition for EPA:

{
"name": "Treatment",
"createdDate": "Thu Sep 10 2015",
"epaType": "Basic",
"context": "TContext",
"inputEvents": [

{ "name": "OsmatranjeContextUpdate", "alias": "osmatranje", "consumptionPolicy": "Consume", "instanceSelectionPolicy": "First" }

],
"computedVariables": [],
"evaluationPolicy": "Immediate",
"cardinalityPolicy": "Single",
"internalSegmentation": [],
"derivedEvents": [
{
"name": "TreatmentAlert",
"condition": "osmatranje.stetocina_id = 22 or
osmatranje.stetocina_id = 29 or osmatranje.stetocina_id = 30 or
osmatranje.stetocina_id = 36",
"reportParticipants": false,
"expressions":

{ "Duration": "0", "mesto_id": "osmatranje.mesto_id", "stetocina_id": "osmatranje.stetocina_id", "level": "if osmatranje.vrednost > 100 then 2 else 0 endif", "entityId": "osmatranje.mesto_id ++ \"-\" ++ osmatranje.stetocina_id", "entityType": "\"TreatmentAlert\"" }

},
{
"name": "TreatmentAlert",
"condition": "osmatranje.stetocina_id = 13",
"reportParticipants": false,
"expressions":

{ "Duration": "0", "mesto_id": "osmatranje.mesto_id", "stetocina_id": "osmatranje.stetocina_id", "level": "if (osmatranje.vrednost >=5 and osmatranje.vrednost <=8) then 1 elseif osmatranje.vrednost > 8 then 2 else 0 endif", "entityId": "osmatranje.mesto_id ++ \"-\" ++ osmatranje.stetocina_id", "entityType": "\"TreatmentAlert\"" }

}
],
"derivedActions": []
}
],
The rule for "level" calculation depends on "stetocina_id".
If I send the request:

{"Name" : "OsmatranjeContextUpdate", "stetocina_id" : "36", "mesto_id" : "20034", "vrednost" : "6"}

I expect to use the 1st rule, and "level" should be 0, but it uses the 2nd
rule and I get 1.

We are using the CEP VM from from FIWARE cloud, we can provide its public IP
address if necessary. The CEP is connected with Orion which has also a public
IP, it is possible to query the alert in Orion.

Best regards,
Janos

Dear Janos,

I would like to investigate your bug report, in order to do that I need
your complete definition set. Could you please export it to a file and
send me this file?

As a work around before I analyse the problem, you can create two EPAs,
one for each derived event, and move the condition to the participant
event table.

Thanks,
Tali

Dear Tali!

Thank you for your answer.

I have already divided the EPA, I'm sending the current json. The only
difference is that I wanted one EPA, 'Treatment' instead of current
'Treatment8' and 'Treatment100'.

Best regards,
Janos

Dear Janos,

Glad you to hear you found the work around. Thank you for sending your
definition file. I saw you added the condition in the Derivation tab.
Please note that you could add it as a condition over the participant
event in the Event Selection tab.

I will open a bug report to our development team to investigate it.
Thanks,
Tali

Dear Janos,

While I created the bug report, I examined your e-mail with the previous
EPA definition and I noticed you added the same event twice as derived
event (with two different conditions, and with different value assignments
in each case). Currently the CEP doesn't support this option. So your work
around is the right way to implement what you wanted.

I will open a bug report, since we should alert the user that this is not
supported as part of the verification, or we should add support for it.

Thanks,
Tali
