XPage ajax文档创建

这可能看起来像重复，但请先阅读，如果你有问题请告诉我。我有一个具有两个数据源的单个xpage，一个用于信息表单，另一个用于图像附件。现在，与典型的应用程序不同，我不想将图像附加到现有的主数据源(第一个)，我想异步上传图像并为每个图像创建单独的文档，主数据源的UNID作为新图像文档的subID。这就是当前数据结构的方式我对改变它几乎没有发言权，所以这是一个挑战。

我已经成功地创建了xhr请求(在Julian和Sven之前的各种异步上传者作品的指导下)，并使用我编写的自定义控件创建了带有图像的新文档，但是一旦我将其嵌入到带有两个数据源的XPage中，并尝试上传和创建新文档，它就会创建主数据源的副本并删除所有其他字段值(具有空字段的副本的预期行为)。我怀疑这是因为我使用$$submit和我的上传请求所需的所有表单值，它们以某种方式与第一个数据源绑定或共享，但我不能太确定。

我的自定义控件有它自己的数据源和xpage有一个面板的数据源作为它的一部分。自定义控件
