View instance within ViewContainerUIElement

Hi,

I have a Main-View V_MAIN with a ViewContainerUIElement which displays the Sub-Views V_SUB1 and V_SUB2 etc. If I navigate to the next View, I want to check the mandatory fields of the current view with method WDDOBEFOREACTION of V_MAIN.

I've found this solution: http://scn.sap.com/message/10266248#10266248 This will work but it will give me the Runtime Repository Object of the View (IF_WD_RR_VIEW) but I need the View or View Controller for checking mandatory fields with CL_WD_DYNAMIC_TOOL=>CHECK_MANDATORY_ATTR_ON_VIEW( ).
