How to update a Google Document?

[Mark]

Hi,

I've spent a lot of time researching all the different ways to update a google document (and spreadsheet) using GWT and have been unsuccessful.

I followed the tutorial here to be able to query my document's list.  I can successfully update the titles, authors, create new documents and delete entries:

http://code.google.com/p/gwt-gdata/wiki/QueryingOtherGDataSystems

However, when I submit an update to a document's contents it will come back successful but not actually change the documents contents.  For example this:

targetDoc.setContent(Text.newInstance());

targetDoc.getContent().setText("UPDATED!");

targetDoc.updateEntry(new DocumentEntryCallback() {

...

}

I also have tried to view the contents (targetDoc.getContent().getText()) of the document but it just says "NULL". 

I have also reviewed the following on a JavaScript implementation:

• Using JavaScript Client Library w/ unsupported Services:
• http://gdatatips.blogspot.com/2008/12/using-javascript-client-library-w-non.html

 

• Create new Docs Spreadsheet using AJAX JS (uses some netscape.security.privledge manager ):
• http://gdatatips.blogspot.com/2009/07/create-new-google-docs-spreadsheet-from.html

But not sure how I can port this to writing to a spreadsheet using this GWT API.

My ultimate goal is to read write data to a google spreadsheet.  

ANY HELP WOULD BE VERY MUCH APPRECIATED!!!
