LibreOffice Array of Array

[Gribo]

Hello, I am trying to copy multiple cells in LibreOffice, using the UNO API. I encountered an issue in the XCellRangeData object.

The object's method returns an array of array of any() type. it seems LV can't compile this, even though the wire appears not to be broken. If I try to parse the array of array into a single dimension and then rebuild, the code is broken. See the attached files. Is there a solution for this issue? The alternative would be to copy cells one by one, which is a much slower solution.
