Xpages是在视图中循环并进行更改的最佳方式
这个问题快把我逼疯了 我可以查看带有类别的文档。现在文档的顺序是任意的，但是我想为用户提供一种简单的方法来上下移动类别中的文档。因此，视图中有上/下箭头 我在箭头后面有SSJS代码，可以更改文档中的“订单”值，以便它们可以向上或向下移动（在我的pick中，任务字段显示订单） 我的问题是它间歇性地工作。我想原因是因为我在循环中时，文档的顺序正在改变。我尝试将视图上的自动更新设置设置为手动，但它似乎仍然不起作用 也许我是在走这条路去硬的。我真的只需要更改两个文档，一个是用户选择的文档，另一个是他们将其移动到的文档。仅仅抓住这些可能会更简单吗Xpages是在视图中循环并进行更改的最佳方式,xpages,Xpages,这个问题快把我逼疯了 我可以查看带有类别的文档。现在文档的顺序是任意的，但是我想为用户提供一种简单的方法来上下移动类别中的文档。因此，视图中有上/下箭头 我在箭头后面有SSJS代码，可以更改文档中的“订单”值，以便它们可以向上或向下移动（在我的pick中，任务字段显示订单） 我的问题是它间歇性地工作。我想原因是因为我在循环中时，文档的顺序正在改变。我尝试将视图上的自动更新设置设置为手动，但它似乎仍然不起作用 也许我是在走这条路去硬的。我真的只需要更改两个文档，一个是用户选择的文档，另一个是他们

嗯，我认为有几种方法可以做到这一点。我没有确切的答案，但如果时间允许，我有兴趣进一步探索。 你不会说有多少文档或者排序顺序是什么。但是如果文档包含排序顺序的字段，那么你就可以很容易地进行操作，只需进行视图刷新。不过我假设这不是一个选项。 我相信java.util.ArrayList会控制插入对象的顺序。如果不是，那么可能是LinkedList。无论如何，如果你创建了一个列表，然后在视图中循环添加文档unid到列表中。那么理论上你就有了一个按视图顺序排列的unid列表。NotesViewNavigator和NotesViewEntry应该可以很快做到这一点。现在你可以我将其转换为一个repeat控件，从UNID获取文档，然后再获取您想要的任何其他值。 那么你会如何影响顺序呢？如果单元的列表在范围内，或者你只需要一个Java方法来“上移”或“下移”。我看到这个问题，它看起来像是一个Collections.swap方法。即使这不是答案，也一定有一些很酷的Java解决方案。 无论如何，这不是一个明确的答案，但也许有一些想法让你去追求
（请确保在获得最终解决方案后发布。）您必须拥有SSJS解决方案还是基于Java的解决方案？我没有说我有什么，但我只是想知道。此外，我不明白为什么您要调用tskView.refresh（）就在您获得视图之后。我看不出性能受到影响有任何意义…Java就可以了。至于刷新，只是为了确保在我的测试中刷新它。我会在生产中关闭它。我现在想知道如果根本不做循环是否会简单得多。用户正在移动当前文档（他们点击箭头的那个）向上或向下。抓取当前文档，然后抓取上一个文档或下一个文档，这取决于他们选择的是向下箭头还是向上箭头。只需交换两个文档的顺序并保存。也许这就是解决方法？Dave我仍在研究我的解决方案，完成后会发布，或者如果无法解决问题，会与您联系，但我想我也是这样戴夫，我找到了一个我认为非常好的解决方案，并把它贴在上面。
