thanks again for your help, I looked up the Completion.hs file in http://darcs.haskell.org/gtk2hs/demo/treeList/ and it was just what I needed, now I can use the new ListStore also for a ComboBox, entry completion and as a CellComboBox box in a ListView.
One side note I did not found Completion.hs in the demo folder of my expanded source tree although it was available on the demo website, it could be usefull that for the next release this is also included in the demo folder in gtk2hs-0.9.13.tar.gz
Again thank you very much for your help

True again, our documentation should really say *don't use this*.
The approach with the new API is very different and much easier (but you

need to forget how the C API works).
Generally, you don't use column ids anymore. The simplest demo that
shows off how you build a list is in demo/treeList/ListDemo.hs . All the
other files use some sort of ColumnId but that's for advanced features
like special widgets (combo boxes, icon view), sorting or completion.
