[fpc-pascal] Is there a way to avoid class casting?

[Horacio Jamilis]

Thanks for the answer but... the problem is more complicated...

Even if I create a descending class for each TLinkedObjectProperty... I 
will not be able to use them...

Because I have 1 class per unit, y can´t have references to the item 
class in the interfase of the new class, because this way I will have a 
lot of circular references

I don´t see a solution... except keeping casting :-(
