Numeric Input field - contains zeroes after initializing

Question

Hello,
I have a input field for R/3 reservation number which is numeric. When the view is first displayed the input field is blank. If If leave this view and return I am clearing the field using the following
<b>wdContext.currentBapi_Reservation_Getdetail_InputElement().setReservation(null);</b>
The field is cleared as expected but is now filled with Zeros.  How can I clear this field but avoid having it filled with zeros. Need to have the field empty as it the first time it is displayed.
Regards,
Keith L.

Hi Baskaran,
I tried setting to "" instead of null and get the same results. What is strange is that If I try to set to "ABC" or any other character string it dumps with the following error.
If I try and set to numberic value "123" it is ok but once again it includes leading zeros.
Error stacktrace:
com.sap.aii.proxy.framework.core.DataAccessException: Type conversion error, field RESERVATION, complex type class XYZ.com.gm8.Bapi_Reservation_Getdetail_Input
<b>wdContext.currentBapi_Reservation_Getdetail_InputElement().setReservation("ABC");
wdContext.currentBapi_Reservation_Getdetail_InputElement().setReservation("123");</b>
Any ideas on where the enforcement of numneric is at? From what I see in the data dictionary entries created by Adaptive RFC it is defined as a string
Rgds,
