I use Eclipse 3.3.2 on WINDOWS XP.
trace it down to StorageDocumentProvider.createDocument(Object element),
where 'element' is FileStoreEditorInput. Fails on the
setDocumentContent(...) call, thus return a null IDocument! Is this
expected behavior?
protected IDocument createDocument(Object element) throws CoreException {
if (element instanceof IEditorInput) {
IDocument document= createEmptyDocument();
if (setDocumentContent(document, (IEditorInput) element,
getEncoding(element))) { setupDocument(element, document);
return document;
}
}
return null;
}

Getting somewhere, override the below method in my document provider
class, which extends FileDocumentProvider. Works but not able to edit
the opened file (the file outside of the workspace opened via
'File->Open File')...Tips???
@Override
protected IDocument createDocument(Object element) throws CoreException {
// Call super for the case of FileEditorInput.
IDocument doc = super.createDocument(element);
// File outside of the workspace? That is, opened via 'File->Open File'.
if (doc == null) {
if (element instanceof IURIEditorInput) {
IURIEditorInput ei = (IURIEditorInput)element;
doc = createEmptyDocument();
// Open the stream
InputStream is = null;
try {
is = ei.getURI().toURL().openStream();
setDocumentContent(doc, is, getEncoding(element));
// setupDocument(element, doc);
} catch (IOException ex) {
Activator.getDefault().log(IStatus.ERROR, ex);
} finally {
try {
if (is != null) {
is.close();
}
} catch (IOException x) {
Activator.getDefault().log(IStatus.ERROR, x);
}
}
}
}
return doc;
}

Got it...One more override to my document provider class.
/**
* To support opening of non-workspace resource, that is, via
* "File->Open File".
*/
@Override
public boolean isModifiable(Object element) {
boolean modifiable = super.isModifiable(element);
if (!modifiable) {
// TODO: Should really make this as a preference setting, so
// that people can look at source-code-controlled file read-only.
modifiable = (element instanceof IURIEditorInput);
}
return modifiable;
}

I spoke too soon...The TextFileDocumentProvider does the trick, but now
if I open resources (files) in the workspace, my none of my resource
related, such as, annotations, spelling checks, etc., does not work :-(
Is it because TextFileDocumentProvider only deals with non-workspace
resources? Thanks

No, it works for resources and everything that's backed by a file store
(e.g. local files). Not sure why it's not working in your case. I
suspect that the annotation model is 'null' for some reason.
