dispatchEvent() throws exception

I'm using Element.dispatchEvent() method to dispatch native event in GWT like this:

final NativeEvent nativeEvent = event.getNativeEvent();  Scheduler.get().scheduleDeferred(new Scheduler.ScheduledCommand() {      @Override      public void execute() {          element.dispatchEvent(nativeEvent);      }  });

Method dispatchEvent() is provided by GWT and looks like:

public final void dispatchEvent(NativeEvent evt) {    DOMImpl.impl.dispatchEvent(this, evt);  }

This code throws exception with the following stack trace:

com.google.gwt.core.shared.SerializableThrowable: (undefined) : DOM Exception: NOT_SUPPORTED_ERR (9)          at com.google.gwt.core.client.impl.StackTraceCreator$CollectorEmulated.$fillInStackTrace(StackTraceCreator.java:180) ~[gwt-servlet-2.6.0.jar:na]          at java.lang.Throwable.fillInStackTrace(Throwable.java:518) ~[na:1.8.0_31]          at java.lang.Throwable.Throwable(Throwable.java:51) ~[na:1.8.0_31]          at java.lang.Exception.Exception(Exception.java:25) ~[na:1.8.0_31]          at java.lang.RuntimeException.RuntimeException(RuntimeException.java:25) ~[na:1.8.0_31]          at com.google.gwt.core.client.JavaScriptException.JavaScriptException(JavaScriptException.java:117) ~[gwt-servlet-2.6.0.jar:na]          at com.google.gwt.lang.Exceptions.getCachableJavaScriptException(Exceptions.java:45) ~[na:na]          at com.google.gwt.lang.Exceptions.wrap(Exceptions.java:29) ~[na:na]          at com.google.gwt.dom.client.DOMImplStandard.$dispatchEvent(DOMImplStandard.java:69) ~[gwt-servlet-2.6.0.jar:na]

It seems that dispatchEvent() is not supported by the some elements, but I'm not sure which exactly.
