[Java] Merging documents

[Glob]

Hello.
I'm trying to merge a document into another one, using Java and UNO on a Win32 OOo 2.2.

I translated some code snippets from Basic into Java, and I finally got something working using DispatchHelpers and UNO urls like ".uno:Paste".

The problem is: that DispatchHelper technique only works on visible documents, it just does nothing at all on hidden documents. I need something working with hidden docs.

So... what should I do? Upgrade to OOo2.4.x, call some functions to prepare the doc to be drawn on an hypothetical hidden backbuffer, or maybe try another technique? (XTransferable maybe?)

Thanks,

Glob
