Project Details are :
https://paste.apache.org/cpo8y
Test case is available on VDI.
Go to Inventory from Select in Menu
Go to PSSM -> Orifice Metering from Setups in Menu
File : com/dbz/modules/Common/dbzPlannimetryMaster.mxml

Click on Plus(+) button popup will be opened, In this Popup **From Field** and **To Field** **AM/PM** is separated,but i am unable to select 2 radio buttons **AM** or **PM** for **from field** and **AM** or **PM** for **To field**.
It is necessary to select one radioButton from **From Field** and one radioButton from **To Field**
System is allowing to select only one radio button from these 4

We are using our custom File dbzDateTimePicker for radiobuttons in dbzPlannimetryDetail.mxml like

```
s:Label id="FromTimeLabel" text=" From Time" x="60" y="37" verticalAlign="middle" height="20" width="111" textAlign="right"/>

```

these radiobuttons are in our library file : dbzDateTimePicker.mxml which is in DbizLib
Path : D:/DbizLib/src/com/dbz/modules/components/dbzDateTimePicker,mxml
