Hi, I'm trying to write a siddhi custom output attribute aggregator for CEP. I wrote the following 2 classes and created the jar file with extension Name=ext1 and function Name=StdDev_sample. StdDevOutputAttributeAggregatorSample StdDevOutputAttributeAggregatorSampleFactory
And then I added the jar file to <CEP_HOME>/repository/components/lib and then added the fully qualified class name as "org.wso2.siddhi.extension.StdDevOutputAttributeAggregatorSampleFactory" to <CEP_HOME>/repository/conf/siddhi. But when i try to use the extension in CEP i get the following error. No extension exist for OutputAttributeExtension{extensionName='ext1', functionName='StdDev_sample', rename='std'} Thank you. -- Nishali Wijesinghe Intern - Engineering WSO2, Inc. lean.enterprise.middleware.
