Hello everyone,

Im looking for help with a slight problem i have.

Inside my app i do something like this:

List: @ScrolledList
  (#
     defaultActionCallback:: 
       (# item: @motifstring; posofitem: @integer; 
       do
          data.item->item;
          item->itempos->posofitem;
          posofitem->putint;
          posofitem->Mailhandler.getentry->editor.value;
        #);
         init:: 
           ...; 
     #);

The problem now is that no matter wich listentry i doubleclick,
resulting in the defaultactioncallback, posofitem always is 0.
Looking at what itempos is doing i see that it calls XmListItemPos.
Now, looking in my ORA Motif Programming Manual, i see that
XmListItemPos returns 0 if it didnt find the item in the list.
Why cant it find the item?
As I look for an item wich i very well know to be there, i selected it
from the list after all, i dont see how this is possible.

Can anyone help me with this?

Regards,
	Arne Hueggenberg
