How to make a repository store inside script?

If I have a script with:

ExampleSet es = operator.getInput(ExampleSet.class);
Return es;

And then connect this script to a store operator.
I get this error:
Mandatory input missing at port Store.input.

The script runs fine, but this error probably caused because meta data not propagated trough script operator.
If I can just store inside the script, I don't need to use the store operator, and I get a nice process without warnings and errors.

Best regards,

    indeed, the script operator does not generate any meta data. To store an IOObject inside your script, you can just call

    import com.rapidminer.example.ExampleSet;
    import com.rapidminer.repository.RepositoryLocation;
    import com.rapidminer.repository.RepositoryManager;

    ExampleSet es = operator.getInput(ExampleSet.class);
    String location = "//Local Repository/data/test";
    RepositoryLocation repLoc = new RepositoryLocation(location );
    RepositoryManager.getInstance(null).store(es, repLoc, null);
    return es;
