HI,

If you Click Interface Controller only Controller Editor will Open , here you will find four tabs.Click methods Tab declare the method you want here.

when you save you will getting build errors , now go to the Component Controller --> click methods tab --> declare the same methods as you did in the Interface Controller and save the Meta data . now there will no build errors .

go to the Component Controller.java and use the methods which you have declared and implement the functionality.

hope your problem get resolved

Thanks and regards

Hi,

Specify the method signature in interface controller and implement this in component controller.

HI Kavita,

There is no problem for fire plugs .in you application. As 7.1 supports backward compatibility.

If you want to migrate your application then you need to take care whatever coding you have done in interface controller.

and as plugs are defined in interface view controller. when migrating it will be converted according to new 7.1 structure.

please refer
