Yes, because the data structure used is initialized/reinitialized only during layout(), so at least force a call to it as a workaround should be enough > Here is my renderer. When layout() is commented, the column displays empty. I'm sorry but haven't enough time to look at the code in the right way ... can you try to use the classes I committed yesterday (in my additional test/minimal sample), and then see in your Renderer if you can do the same as in mine ? Tell me. Bye
