I want to create a new class for that I have made all the changes given in these links
http://docs.rapidminer.com/developers/creating-your-own-extension/your-own-operator/
http://docs.rapidminer.com/developers/creating-your-own-extension/your-own-operator/configurations.html
I changed the code in OperatorTempelate.xml, OperatorDocTempelate.xml, groupsTempelate.properties and insert icons
and then I installed the extension and it gives me no error
when I checked it in rapid miner no such operator has been created
Can anyone guide me where i went wrong
