Expression Binding - custom function call

[Former Member]

Hi all,

I read about new features in sapui5 - function call in expression binding:

Expression Binding - User Interface Add-On for SAP NetWeaver - SAP Library

On this page is only information, that we should call f(...). I try call my function (from view controler) but without success. Maybe someone has working example how to use this new feature, how to define function in view controler and how to use it in XML View?

I found similar question on: http://stackoverflow.com/questions/31615837/call-controller-function-from-xml-binding-expression

But solution from above page: "{= f(checkSelectedItems, null, ${odata>CustomerId}) }" doesn't work.

Thanks,

Maciej

Expression binding is using for simple formatter function. so write the logic in xml view itself. and please share your code and your requirement.
