crosstab different behaviour 3.6.1 vs 3.6.2 and more

[blosser]

hi all. i need help. use crosstab with DataPresorter=true.

I think, that crosstab header can has same value in different colums. JR 3.6.1 works fine (in my opinion), but 3.6.2 was change calculation crosstab header.

datasoure:

select '' gr, 'a' attr1, 'c1' h1, 'h1' h2, '1' val from dual union all

select '' gr, 'a' attr1, 'c2' h1, 'h2' h2, '2' val from dual union all

select '' gr, 'a' attr1, 'c1' h1, 'h1' h2, '3' val from dual union all

select '' gr, 'a' attr1, 'c2' h1, 'h2' h2, '4' val from dual

attach result 3.6.1 and 4.0.0 version
