multi lines dynamic string constants


I have a combobox that is used in many windows, with an initial value of some 25 lines, that are the sames in all the windows
and sometimes these lines change, you can add one line from time to time with a value in it.

so I made a dynamic constant in a module, #kMode with a multi lines value.
this works.

today, I have to add another property to this combobox with other strings.
I made the same other dynamic multi lines string constant #kMode2, and add the property to the inspector behaviour panel.
in each window I set this property to the constant in the IDE

curiously this does not work as I only get the first line of the list in this property
is there a way to do this or do I have to make a bug feedback ?
