Front end KUT field not accepting 0 as avlue.

HI,

I am passing a value from back end (Cloud app studio) through web services for example say passing 1 from back end it is accepting in front end as 1, but when i am passing zero as value it is not accepting instead it is showing previous value i.e, 1. we have checked everything in back end everything is fine. i think there might be some other value in front end for zero.

we have even raised an incident still have not got any prior response.
