ATL program:

-- @path source=file:/.../TPF/source.ecore
-- @path target=file:/.../TPF/target.ecore

module tpf3;
create OUT : target from IN : source;

helper context source!ModuleItem def : getIdentNumber():
String = self.ParameterList.ParameterItem->select(pi | pi.Name='IdentNumber')->collect(e|e.Value)->first();

helper context source!ModuleItem def : getSlotValue():
String = self.ParameterList.ParameterItem->select(pi | pi.Name='Slot')->collect(e|e.Value)->first();

rule Rule_Device{
from
a: source!DeviceItem
to
p:target!Device(
name <- a.Name,
s7DeviceReference<-a.DeviceReference,
HeadModule<-a.ModuleList.ModuleItem->select(mi|mi.getSlotValue()='0')->collect(e|thisModule.Rule_getModule(e))->first(),
Module<-a.ModuleList.ModuleItem->select(mi|mi.getSlotValue()<>'0')->collect(e|thisModule.Rule_getModule(e))
)
}

lazy rule Rule_getModule{
from
b:source!ModuleItem

to
d:target!Module(
deviceID<-b.getIdentNumber(),
name <- b.Name,
s7ModuleReference <- b.ModuleReference,
isSelectedWithinStep7<-b.IsSelected
)

}

Problem: How to get elements in the output file sorted by the Slot Value parameter?

I appriciate any help.

Thanks in advance.
