                                <openui5.googlemaps:Waypoint id = "waypoint" location="{location}"/>
                                <!--<openui5.googlemaps:Waypoint location="Talod"/>-->
                            </openui5.googlemaps:waypoints>
                        </openui5.googlemaps:Directions>
                    </openui5.googlemaps:directions>
                </openui5.googlemaps:Map>
                <Input id="start" value="{start}" width="180px" placeholder="Start Address">
                    <layoutData>
                        <FlexItemData growFactor="2"/>
                    </layoutData>
                </Input>
                <Input id="end" value="{end}" width="180px" placeholder="End Address">
                    <layoutData>
                        <FlexItemData growFactor="2"/>
                    </layoutData>
                </Input>
                <Button text="Find distance" type="Emphasized" width="170px" press="go"></Button>
            </content>
        </Page>
    </pages>
</App>

上面的代码是视图。我正在添加控制器的代码，但无法添加它。我对一个起始和结束地址有所需的结果但是我无法在开始和结束地址上有多行相同的map.I需要多个带针点的线，如图所示。
