DS 1.3 SDK DataCell scaling UOM -ve data inconsistency

Hello Experts,

I am facing the issue with Data Cell displaying inconsistent scaling, Inconsistent UOM display & -ve numbers being concatenated as '-'2.5% with the Design studio SDK DataBinding Interface "ResultCellList" and CVOM library to format cell value

I have used the SAP provided function formatValue(value, tuple) for cell formatting and it uses the below SAP CVOM library.
sap.common.globalization.NumericFormatManager.setPVL(meta_data.locale);
return sap.common.globalization.NumericFormatManager.format(value, strFormat);

Design studio BIP version 1.3 SP01
Design studio client Tool 1.3 (Version 13.0.3.201405141058)

Used the SAP sample component AS-IS for testing just the Datacell formatting (com.sap.sample.simpletable). Please find attached screenshot in "com_sap_sample_simpletable.PNG".

Have anybody faced this problem and is anyone aware of the CVOM library Standard Crosstab uses and it seem to work correctly for the same BEX query. Please advice.

Thanks

Arun
