Hello,



I need to store references to interfaces in a list so that when the user
selects a list item I can easily access the interface that relates to
that item. I've been casting the interface as a pointer and adding it as
the list items object. Now when I try to retrieve it I try to cast it
back and the compiler moans that you cant cast a TObject to an
interface. I tried casting it to a pointer first and then to the
interface type which the compiler likes (see code below). The problem I
have then is that when the code runs, when the following line runs it
throws an exception. My question is, Is there a better way to do what I
need to do and what is causing the problem with this code. I must say
that I'm not 100% when it comes to interfaces.



Item := IJanusDataSourceItem (pointer (ListItemObject)) ;
