Using Map instead of String properties with ActionForm.

Since 1.1b

    private Map values = null;

    public void setValues(Map values) {
        this.values = values;
    }
    public Map getValues() {
        return this.values;
    }

    public void setValue(String key, Object value) {
        getValues().put(key,value);
    }
    public Object getValue(String key) {
        return getValues().get(key);
    }
