An error occurs when changing the stlyes of an OOo document using the Zotero 1.0.3. add-on toolbar (As I use German styles this problem may only occur in German language versions, I can't verify that.):

1. Insert an item with style Chicago (full note with bibliography).
2. Change the style to Harvard format 1 (author date).
3. Error: Basic runtime error. / An exception occured. / Type: com.sun.star.uno.RuntimeException / Message: this object is invalid.
The makro console opens and shows this line: "oRange.text.insertTextContent (oRange, oField, true)" (see screenshot:

)

I'm having the same problem. I switched a document from Chicago Author-Date to Chicago Note with Bibliography, but now I can't change it to any other style. I'm using Zotero 1.0.7 and Firefox 3.
