"brackets in Generate Attribute operator"
The generate attribute operator has a field "function expression".
If I use this field and select an attribute with brackets: prediction(label) then I get a syntax error
-> Unrecognized symbol prediction.
-> Unrecognized symbol label. (because the select attributes operator is applied)
-> syntax error (implicit multiplication not enabled)
This is what I want to implement:
function expression: attr1 + "_" + prediction(attr2) + "_" + prediction(attr3)
If I use concat(attr1, prediction(attr2)) I get the same error.
