Hi,
I've tried adding a new gadget to CEP as mentioned in the getting started
with CEP guide<https://docs.wso2.org/display/CEP310/Getting+Started+with+CEP>
.
When I tried 'Select Dataset' in the 'Add Gadget' workflow it throws an
error (copied at the end), this is due to a back-end error trying to access
an empty array (/cep-dash/apis/gadget-gen.jag#86).
This workflow works well with the a data populated table.
CEP Error
