Koen, wt 3.2.2.2-rc1 solved the problem. For some reason I can not generate
the isapi lib with this new version, but I am working on it.
Thanks a lot.

I believe we have fixed this bug recently.
The fix is the following:
diff --git a/src/Wt/WSortFilterProxyModel.C b/src/Wt/WSortFilterProxyModel.C
index 1b3f08e..b85f303 100644
--- a/src/Wt/WSortFilterProxyModel.C

No, it should be okay to load data in the source model
(WStandardItemModel in this case).

Because of bug
Can you try if applying the fix above (or moving to 3.2.2-rc1)
resolves the issue ?
