Problem description: 

I have the following code many times in my pretty large LO Basic section (with variations in cell range and search criteria):

Functions = createUnoService("com.sun.star.sheet.FunctionAccess")
dim StudentsArgs(2) as variant
StudentsArgs(0) = Index.Formula 'just some string to search for
StudentsArgs(1) = StudentiSheet.getCellRangeByPosition(StudentiIndeksCol,STUDENTIHEADERROW+1,StudentiIndeksCol,StudentiEndRow) 'some cell range for searching
StudentsArgs(2) = 0
StudentRow = Functions.callFunction("MATCH", StudentsArgs())

In Ubuntu 13.10 I am using LO from LO PPA, version 4.1.3.2 and the code above works as expected (it returns the row number).

A few days ago I tried Ubuntu 14.04 that comes with LO 4.2.3.3. In this version, calling a MATCH function always returns me Variant/Empty instead of row number. All the parameters have the same value in both versions of LO before reachng MATCH call (I checked in debugger).

Was there some change in callFunction mechanism, or the way that MATCH function works between the versions?

I cant't at the moment make an example ods for testing, but I can in a few days, if needed.
Operating System: Ubuntu
Version: 4.2.3.3 release
Last worked in: 4.1.3.2 release
