我在使用共享调用时遇到了一个奇怪的错误.

I have a strange bug using a share invoke.

约有三分之一的尝试共享将导致没有文本被共享.通常，第一次共享将起作用，但进一步的尝试将不起作用.它将随机再次开始工作. BBM，Facebook和Twitter应用程序会发生这种情况.

About 1 in 3 attempts to share will result in no text being shared. Usually the first share will work but further attempts will not work. Randomly it will start working again. This happens with bbm, facebook and twitter apps.

以下代码是listview列表项的一部分.

The following code is part of a listview listitem.

InvokeActionItem { id: invokeActionItem title: "Share" ActionBar.placement: ActionBarPlacement.OnBar imageSource: "asset:///Images/Icons/share_icon.png" query { mimeType: "text/plain" invokeActionId: "bb.action.SHARE" } onTriggered: { query.data = "I just read this and had to share it: " + ListItemData.title + ". "; query.data += "Read it here " + ListItemData.shareUrl; query.updateQuery(); } }

有没有人知道可能是什么原因或如何解决此问题?

Has anyone got any ideas what could be causing the issue or how to solve it?

推荐答案

不幸的是，在QML中，调用已中断(有时仅适用于文本).您将需要使用C ++(在这里可以很好地工作)

Invocation is unfortunately broke in QML (works only for text sometimes). You will need to use C++ for it (it works well there)
