In the Create Work Order - html page. When i select the WO type, the flexfield context doesn't get t

I have the Work in Process - Discrete Job Flexfield, configured that the flexfield context sinchronizes with reference field : WORK_ORDER_TYPE_DISP.

In the Work Order Form, the Context field get synchronized at the time i chose the work order type.

But in the HTML page for the create work order, it doesn't happen the same way, the user have to choose the Context Field, and you can choose a diferent value than the work order type.
