Switching between function declaration and definition not working in qml

while working in qml, i m not able to switch between function declaration and definition in qt 16.0.2, this working fine in previous version of qt framework. 

suppose if i have to switch in qml file, i m not able to switch its declaration in both ways from as string and as a component.
eg -> "xyz.qml" or xyz{} both are not working while pressing f2
