Hi
You have probably done initialization in wrong way. It should like like this
(it's my case if you don't have clients you just use Empty ones):
m_pChromeClient = new WebChromeClient();
m_pContextMenuClient = new WebCore::EmptyContextMenuClient();
m_pEditorClient = new WebEditorClient();
m_pDragClient = new WebCore::EmptyDragClient();
m_pInspectorClient = new WebCore::EmptyInspectorClient();
// For WebCore::Frame
m_pFrameLoaderClient = new WebCore::WebFrameLoaderClientCE();
m_pPage = new WebCore::Page(m_pChromeClient,
m_pContextMenuClient,
m_pEditorClient,
m_pDragClient,
m_pInspectorClient);
Now Page has its own chrome client.
