Setting default values in component controller while using FPM application

Hi,

Whenever a Tab is changed in FPM OVP, I am trying to default some values in Component controller context. ( These default values I am further using in the relevant views )

I have written the related code in the OVERIDE method of component controller, but when coming out of this method, the values in the component controller context are getting errased.

Please let me know how to default some values in component controller when a FPM tab is selected. Checked in PROCESS EVENT method also...

Thank you!
