I know this page.
And yes in many cases this helps (waiting for upcoming windows, and so on)
the problem in this cases seems to be an other one.
The elements in the ComboBox are implemented with Lazy Loading.
And it is terrible that for many cases white can't select an existing element
I have implement a check before selecting the element. It loops over all items and looks for the searched one.
This check never fails. So It seems not to be a wait problem as I expect first.
The element is there.
If I use combobox.selectItem("name"); I don't get any failure but the element is not selected. (the default one is selected again)
so I get the item from the combobox I wan't to select, and use item. Select(). this works better, but sometimes the above described problem occurs again.
The problem is new. first the normal way works. Than the developer implement that the Tool remember the latest selected element, (In the past the first element was selected by default) . In the next tool start this element is selected as default.
After that the problems oocur.
