Thanks for the help Stephen, but it doesn't work even using wide character (and even without using the L prefix, I guess it would be cast to wide by the CString constructor).
I think the problem is that the Refresh is working for the PPG layout but not to update the internal combo list array. Using a custom property, I could probably do it in the init callback (thanks to Eric Thivierge for the idea), but custom primitives (that are a nice 2014 feature btw) don't provide such callback.
