Hi folks , i,m trying to do a loop that collect me objects that meet a property , this looks me several days , and i can,t to find the mistake , maybe somebody can to help me , thanks , this is the code :

for p in (self.paquetes -> collect( p | p.tiempoRestante = 0)) do
declare ns : Servidor , nt : Transmisor ;
if (self.servidor -> notEmpty()) then
ns := self.servidor -> sortedBy(n | n.paquetes -> size()) -> any(true) ;
self.transmitirS(p , ns) ;
nt := self.nodo2 -> sortedBy(n | n.paquetes -> size()) -> any(true) ;
delete (self,p) from Procesando ;
insert (nt,p) into Procesando ;

At compile time it says to me that p , in self.transmitirS(p,ns) , is a boolean and not an object , it have to be an object of self.paquetes , why is a boolean ??? . thanks

While there are some sub-expressions in your example that are probably OCL, the example as whole is clearly not OCL. OCL has no begin/for/do/end/insert/delete/:=/boolean/declare/into/from.
