Hi, I´m trying to run my own procces in java, the code is the following: 
RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
        RapidMiner.init();
        Process p = new Process(new File("C:\\Users\\hugo\\Desktop\\ProyectoFinal\\SetRole.rmp"));
        IOContainer ioResult = p.run();

        // use the result(s) as needed, for example if your process just returns one ExampleSet, use this:
        if (ioResult.getElementAt(0) instanceof ExampleSet) {
            ExampleSet resultSet = (ExampleSet)ioResult.getElementAt(0);
            IOObject o= (IOObject)resultSet;
        }
but sometimes when i run it (Not always, and if I try to run it creating another project it also works) it gives me the following problem.
Información: The parameter '<code>attribute_name</code>' is unknown for operator '<var>Set Role</var>' (<code>Set Role</code>).
