You didn't obey JavaFX specific accessor syntax in your Room datamodel:

If the field is ObservableValue like:

private StringProperty val = new SimpleStringProperty();

There should be accessors as:

public String getVal() {
    val.get();
}

public void setVal(String newVal) {
    val.set(newVal);
}

public StringProperty valProperty() {
    return val;
}

Note the method valProperty. Also see this Q&A entry.
