I have this problem currently in all my applications. To simplify I have created a Test application with the following form:

1. form  Untitled_Form
2. {
3.     displayname  =  "Untitled Form"
4.     field alignment = left
5.     
6.     Checkbox
7.     (
8.         type  =  checkboxes
9.         values  =  {"Choice 1",   "Choice 2",   "Choice 3"}
10.     )
11. 
    
12.     Choices
13.     (
14.         type  =  checkboxes
15.         values  =  Choices.ID
16.         displayformat = [ Single_Line ]
17.         sortorder = ascending
18.         searchable  =  true
19.     )
20. 
    
21. } 

The standard checkboxes show up fine on the form, but the lookup field that should show checkboxes based on records in the Choices form, do not show as checkboxes...

Am I the only one with this bug? It used to work, some time ago.

Cheers!
