Eclipse RCP XMLMultiPageEditorPart errors

all When I use XMLMultiPageEditorPart, it makes some errors.

File file = new File(path);

   IEditorInput  input = new XMLPInput(file);

   try {
    page.openEditor(input, "org.eclipse.wst.xml.ui.internal.tabletree.XMLMultiPageEditorPart");
   } catch (PartInitException e) {

    MessageDialog.openError(window.getShell(), "",  path);
   }

Errors:

org.eclipse.ui.PartInitException: Text editor does not have a document provider at org.eclipse.ui.texteditor.AbstractTextEditor.internalInit(AbstractTextEditor.java:3075) at org.eclipse.ui.texteditor.AbstractTextEditor.init(AbstractTextEditor.java:3088) 开发者_如何学Pythonat org.eclipse.wst.sse.ui.StructuredTextEditor.init(StructuredTextEditor.java:2553) at org.eclipse.ui.part.MultiPageEditorPart.addPage(MultiPageEditorPart.java:237) at org.eclipse.ui.part.MultiPageEditorPart.addPage(MultiPageEditorPart.java:211)

I think XMLMultiPageEditorPart should has its own provider? could anyone help me ?

Where did you get the class XMLPInput from? As you are using File, why can't you use the standard FiledEditorInput or FileStoreEditorInput?
