migration to 8.0 issue

[Guest_imported]

I am doing migration process from 5.0 to 8.0 on windows .
I got a weired problem that the data file worked fine with the 5.0 version. But when the same file I run through 8.0 got an "input contains invalid data" error.
--------------------------------------
The typetree properties are :
item subclass: number
interpret as : character
presentation : Decimal
size Min: 0, Max = empty
Seperators: YES
Format: ####[.##]
fraction syntax: literal
value: "."
Sign= Yes
value: leading-
---------------------------
I checked the trace file attached the results out of trace: only the record with the following value casuing issue.

(Level 2: Offset 41343, len 17, comp 9 of 38, #1, DI 000002A0
Data at offset 41343 ('-000000000000000...') failed item presentation test for TYPE
X'0011' (ACCTBAL DecimalField EquityMTM CP216MTM).

I found the solution for the Tricky issue.

In the 5.0 version type tree does have empty value at the "sign/value/if Number is 0" .
when you migrate this typetree to the 8.0 "sign/value/if Number is 0" defaults to "+" sign.
So,when you have "-0" in the input map get failed with the "input invalid " error.
