Description

Accessing:

import org.apache.flink.table.planner.codegen.CodeGeneratorContext;
import org.apache.flink.table.planner.codegen.ProjectionCodeGenerator;

Should not happen in the open() method of an operator. Instead. the code generation should happen during planning and only the compilation should happen in open().
