New Fields save empty in table

Dear all,

I am facing very strange problem after adding new fields in existing table the values in that fields are save empty.

i checked the object in debugger after insert() the values are there in the object but in database fields its empty.

any idea???

Are you have try to delete the field and create new one?

no due to some reason we need to add more new fields. now it is working fine after restarting the AOS.

but why this happen.
