[Bug Report]: 自定义节点锚点的连线无法正确回显

[zhangyfuen]

发生了什么？

自定义节点的锚点以后，锚点之间的连线在提供了type,sourceNodeId, targetNodeId, sourceAnchorId 和 targetAnchorId 几个主要参数后，仍旧无法正确回显。测试发现必须存在startPoint 和 endPoint 就正常了

期待结果

实际结果

hi，请问回填的时候没带startPoint和endPoint是有什么背景吗，理论上 边数据里是有startPoint和endPoint数据的，回填应该是会带上对应数据的

[zhangyfuen]

我最开始用自定义节点做了一个类似的效果，测试时发现它的边回显不需要startPoint 和 endPoint，就以为自定义锚点的边应该也是这样的。。。。

[zhangyfuen]

我有点理解startPoint he endPoint 必须存在的原因了，自定义锚点的位置并不容易内部计算。 如果不是个bug的话，那我把节点位置和边startPoint endPoint都存下来吧
