i have some problem in active record binding for view mode.

Currently when view click.. my record data can't binding to some input control like date picker, collection_select
but it will binding if i change the input control to text_field.
this is appear when i binding using child item instead of parent . (For relationship is has_one relationship means parent only has one child item).

can u give me advice for this ?
How to solve this problem ?

Thanks before...
