setCurrentIndex(-1) and setNoSelectionEnabled(true)
When several linked comboboxes, which are defined in a
WTemplate, are loaded with new data, they are not able to set the current index to --1. Although I regularly call
setCurrentIndex(-1) in combination with
setNoSelectionEnabled(true), only the first time after loading the page, the comboboxes are indeed set to an index of --1 (empty).
