groupChar does not work for integer

[jze]

It seems that the groupChar properties does not work for fields with the type integer.

I have created a minimal example. Although the example seems to be correct the validation says: Type error in the cell "1.001" in row "3" and field "a" at position "1": type is "integer/default"
