Code review comment for lp:~diegosarmentero/ubuntuone-windows-installer/ui-form

Please try to put the strings in constants, and not in the code like "Your password must contain" (line 171 of the diff), which is also used in two places.

Also, since the logic now depends on the tab order, you should add a test that verifies the tab order is the right one. We should also check that the tab order agrees with the vertical order of the fields, but that's probably overkill.
