SQL Widget Mapper Example bug?

[ohmyqt]

Hello all,

I'm trying to learn from the SQL Widget Example, but I have one concern.

After I compiled it, without making any changes, all I did was press the Next button all the way to the end, and then press the Previous button all the way to the beginning, and then Next all the way to the end the 2nd time. It appears that the "Type" data has changed just by doing that. Am I the only one getting this effect?

First time round, beginning to end, the sequence is:
Home, Work, Other, Home, Other. (Correct)

Coming back, the sequence is:
Other, Home, Other, Work, Home. (Correct)

Going back though, I get:
Home, Work, Other, Home, Home. (Huh? Should be 'Other')

What happened?

Thanks, all.
