Prepare the dependsOn nodes

Parameters:

srcBinding - associated binding of the source dependent field; e.g.

srcPath - the source dependent field name series in list. e.g. "vm", "fullname" for "vm.fullname".

dependsOnBasepath - the base path for the depends-on field; e.g. the "vm" of the "vm.firstname"

dependsOnProp - the property name of the depends-on field; e.g. the "firstname" of the "vm.firstname"

Prepare the dependsOn nodes

Parameters:

srcBinding - the binding with the source dependent field; e.g.

srcPath - the source dependent field name series in list; e.g. ["vm", "fullname"] for "vm.fullname".

srcComp - the source component associated with the binding; e.g.

dependsOnPath - the depends-on property name series; e.g. "vm.firstname"

dependsOnComp - the depends-on component associated with the depends-on property name series binding; e.g. "vm.firstname"
