I faced exactly the same problem. In my app wherever i had click events coded using 'touchend' in jquery bind(), this error was coming up and it used to never respond to clicks (taps).. and gave a frozen kind of feel.
So I just tried replacing 'touchend' with 'click' in bind(), and it worked! responded to clicks (Taps) and also didn't show that log entry of webcoreglue.. 

I also found this piece of code in Android's webview code..

<pre><code>HTMLElement* WebViewCore::retrieveElement(int x, int y,
 const QualifiedName&amp; tagName)
{
 HitTestResult hitTestResult = m_mainFrame-&gt;eventHandler()
 -&gt;hitTestResultAtPoint(IntPoint(x, y), false, false,
 DontHitTestScrollbars, HitTestRequest::Active | HitTestRequest::ReadOnly,
 IntSize(1, 1));
 if (!hitTestResult.innerNode() || !hitTestResult.innerNode()-&gt;inDocument()) {
 LOGE("Should not happen: no in document Node found");
 return 0;
 }
 const ListHashSet&lt;RefPtr&lt;Node&gt; &gt;&amp; list = hitTestResult.rectBasedTestResult();
 if (list.isEmpty()) {
 LOGE("Should not happen: no rect-based-test nodes found");
 return 0;
 }
 Node* node = hitTestResult.innerNode();
 Node* element = node;
 while (element &amp;&amp; (!element-&gt;isElementNode()
 || !element-&gt;hasTagName(tagName))) {
 element = element-&gt;parentNode();
 }
 DBG_NAV_LOGD("node=%p element=%p x=%d y=%d nodeName=%s tagName=%s", node,
 element, x, y, node-&gt;nodeName().utf8().data(),
 element ? ((Element*) element)-&gt;tagName().utf8().data() : "&lt;none&gt;");
 return static_cast&lt;WebCore::HTMLElement*&gt;(element);
}​
</code></pre>

and this too..

<pre><code>// get the highlight rectangles for the touch point (x, y) with the slop
Vector&lt;IntRect&gt; WebViewCore::getTouchHighlightRects(int x, int y, int slop)
{
 Vector&lt;IntRect&gt; rects;
 m_mousePos = IntPoint(x - m_scrollOffsetX, y - m_scrollOffsetY);
 HitTestResult hitTestResult = m_mainFrame-&gt;eventHandler()-&gt;hitTestResultAtPoint(IntPoint(x, y),
 false, false, DontHitTestScrollbars, HitTestRequest::Active | HitTestRequest::ReadOnly, IntSize(slop, slop));
 if (!hitTestResult.innerNode() || !hitTestResult.innerNode()-&gt;inDocument()) {
 LOGE("Should not happen: no in document Node found");
 return rects;
 }
 const ListHashSet&lt;RefPtr&lt;Node&gt; &gt;&amp; list = hitTestResult.rectBasedTestResult();
 if (list.isEmpty()) {
 LOGE("Should not happen: no rect-based-test nodes found");
 return rects;
 }
//Rest of the part is omitted here...
</code></pre>

Notice that log message there? I am guessing this code is for identifying the x and y axis vectors generated on clicks or taps or swipes..

blocks|key|277037|text|对于包含WebViews的JellyBean和ViewPager+%2B片段也有同样的问题。在Android2.2上运行相同的代码都没问题，所以我认为这是JB+WebView实现中的一个错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|277038|在JB上，只有第一个显示WebView的片段工作正常，没有错误“不应该发生..”在日志中，getHitTestResult()调用返回正确的值。滑动到下一页，我在日志中看到错误，getHitTestResult()只返回0和null值。|277039|现在，我发现只有一种解决方案可以创建具有空容器的片段，并创建WebViews，设置它们并仅当当前片段在ViewPager中变为活动时才加载数据。在这种情况下，WebView根据需要工作。但是，不幸的是，这完全打破了在ViewPager中平滑滑动页面的想法。|277040|有了最后一个想法，明天将尝试将ViewPager的片段替换为复合视图。可能性很小，但如果结果成功，我会让你知道的。|277041|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

Have the same problem with JellyBean and ViewPager + fragments that contains WebViews. And all OK with the same code running on Android 2.2, so I think this is a bug in JB WebView implementation.

On JB only the first shown fragment with WebView works right, without errors "Should not happen .." in the log, and getHitTestResult() calls returns correct values. Swiping to the next pages, I got errors in log and getHitTestResult() returns only zeroes and nulls.

Now I found only one solution to create fragments with empty containers and create WebViews, setup they and load data only when current fragment becomes active in the ViewPager. In this case WebView works as needed. But, unfortunately, this completely breaks an idea of smooth swiping pages in the ViewPager.

Have the last idea, tomorrow will try to replace ViewPager's fragments to compound views. Little chances, but I'll let you know if results will be successful.

blocks|key|277115|text|这个问题的发生是因为在某些情况下，WebView没有注意到它的可视rect已经改变，所以就webkit而言，页面仍然不可见。因此，所有的触碰都落在窗口之外，并被拒绝。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|277116|最干净的修复方法是，当您知道WebView的可见性发生了变化时(例如响应视图分页程序中的setPrimaryItem回调)，调用webview.onScrollChanged(webview.getScrollX(),+webview.getScrollY());|offset|length|style|CODE|277117|您需要将webview子类化以将受保护的onScrollChanged提升为公共方法。|277118|entityMap^0|0|1S|1W|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

The issue occurs because in some scenarios WebView fails to notice that its visible rect has changed, so as far as webkit is concerned the page is still not visible. Thus all touches fall outside of the window, and get rejected.

The cleanest fix is when you know the visibility of your WebView has changed (such as in response to a setPrimaryItem callback from a viewpager), call <code>webview.onScrollChanged(webview.getScrollX(), webview.getScrollY());</code> 

You will need to subclass the webview to promote the protected onScrollChanged to a public method.

blocks|key|494104|text|当我在Cordova+%2B+Sencha+Touch环境中工作时，也发生了这种情况。因为CordovaActivity没有任何类似于onScrollChanged()方法的东西，所以我不能应用上面的任何解决方案。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|494105|在用头撞墙几个小时后，我发现web界面的某些部分在完全渲染之前就已经被调用了。在我的例子中，这些方法是由Ext.PanelView中的activate事件触发的。我用painted替换了那个事件，从那时起，一切都变得很棒。|494106|虽然它不是复制-粘贴解决方案，但我希望它可以帮助某人节省调查时间。|494107|entityMap^0|17|F|1T|H|0|1G|D|1V|8|2B|7|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|X|8|@]|D|@]|E|$]]|$1|J|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|K|$]]

It also happened to me when I was working in Cordova + Sencha Touch environment. Because
<code>CordovaActivity</code> does not have anything like <code>onScrollChanged()</code> method I could not apply any of the above solutions. 

After hours of banging my head against the wall I discovered that some parts of web interface had been called before this was completely rendered. In my case those methods were triggered by <code>activate</code> event in <code>Ext.PanelView</code>. I replaced that event with <code>painted</code> and since then everything works like a charm.

Although it is not copy-paste solution I hope it may help someone to save time on investigation.

blocks|key|277278|text|甚至我在ViewPager中也有WebView，并通过扩展webview类覆盖onTouchEvent()来修复这个问题。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|277279|下面是我的代码：|277280|@Override

Even I have WebView inside a ViewPager, and fixed this problem by overriding <code>onTouchEvent()</code> by extending webview class.

Here is my code:

<pre><code>@Override
 public boolean onTouchEvent(MotionEvent event) {
 if (event.getAction() == MotionEvent.ACTION_DOWN) { 
 requestFocusFromTouch();
 }
 return super.onTouchEvent(event);
 }
</code></pre>

Cheers !!!

blocks|key|494237|text|我不知道为什么它会起作用。我在我的MainActivity.java中添加了onTouchEvent监听器来解决这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|494238|public+class+MainActivity+extends+ActionBarActivity+implements+ActionBar.TabListener+{

Don't have a clue why it worked. I added onTouchEvent listener into my MainActivity.java to fix this issue.

<pre><code>public class MainActivity extends ActionBarActivity implements ActionBar.TabListener {
 public class MyWebView extends WebView {

 public MyWebView(Context context) {
 super(context);
 }

 public MyWebView(Context context, AttributeSet attrs) {
 super(context, attrs);
 }

 @Override
 public boolean onTouchEvent(MotionEvent event) {
 onScrollChanged(getScrollX(), getScrollY(), getScrollX(), getScrollY());
 return super.onTouchEvent(event);
 }
 }

My application is using a lot of webviews which are lying in fragments which are hold by a ViewPager. 

Whenever i swipe through the app on my Galaxy Nexus with Jellybean on it i get the following console message again and again: 

<pre><code>08-23 13:44:03.374: E/webcoreglue(21690): Should not happen: no rect-based-test nodes found
</code></pre>

Can anyone explain to me what is going wrong here so that i might be able to fix the issue?

Android WebView JellyBean -> Should not happen: no rect-based-test nodes found

Cordova

我的应用程序使用了大量的网页视图，这些网页视图是由ViewPager保存的片段。每当我滑动我的Galaxy Nexus上的应用程序，上面有果冻，我就会一次又一次地收到以下控制台消息：08-23 13:44:03.374: E/webcoreglue(21690): Should not happen: no rect-...
