[Fiware-tech-help] [FI-WARE-JIRA] (HELP-3482) Regarding CEP assertion If condition

[Ahmed Sadek]

Dear Fabiana,

1- What is the format for writing If statement in this assertion so I can
generate event x when condition 1 is satisfied and event y when condition 2
satisfied.
2- When I choose basic EPA, I can not input assertion as it says "
No condition attributes for this EPA type. You may want to change the EPA
type
"

Best,
Ahmed
