Rowset.updateRow() crashes

Hi,

I'm trying to update a bunch of records from BASIC code:

	oRowset = createUnoService("com.sun.star.sdb.RowSet")
	oRowSet.DataSourceName = sDBName
	oRowSet.User = "marc"
	oRowSet.Password = "****"
	oRowSet.ResultSetConcurrency = com.sun.star.sdbc.ResultSetConcurrency.UPDATABLE
	
	'		    
	if update then
		
		oRowSet.CommandType = com.sun.star.sdb.CommandType.COMMAND
		oRowSet.EscapeProcessing = FALSE ' native SQL, ggf. ausschalten!

		' Feldnamen aufbereiten
...
		
		' SchlÃŒssel extrahieren
...

		oRowSet.Command = sSQL
		oRowSet.execute()
		oColumns = oRowSet.getColumns()
		
		' ÃŒber alle Reihen bzw. Elemente der Ergebnismenge
		while NOT(oRowSet.IsLast())
			oRowSet.next()
			
			' Werte neu setzen
			for n=0 to columncount-1

... here the updateXxxx() methods are used to set the new values 

			next
			
			' wegschreiben
			oRowSet.updateRow()
			
		wend
...

The last instruction "oRowSet.updateRow()" crashes on the first call.

Tested on OOo1.1.0/FreeBSD and OOo1.1.1/Win98. The same sequence works
perfectly well if "moveToInsertRow" and "insertRwo()" are used.

My questions:

- Is there anything worng in the function sequence?
- Has a bug in this area been fixed in OOo1.1.3...1.1.5?

TIA,
Marc
