Collaborative Services getDocumentInfo

Hi, I’m trying to read from a Notes 6 database using Collaborative Services (this is from a WebSphere portlet so it’s a Java web app).

I can get ViewInfo and RowInfo with no errors. I can get the UNID of each document in the RowInfo objects.

When I try to use dominoservice.getDocumentInfo the HashMap returned is always null, even if I only pass one field name in the string array and it’s a field name that I know for sure ins in the document.

The doco isn’t much help:

Does anyone have any experience with Collaborative Services? Please?
