OpenLayers悬停时高亮显示功能，然后单击选择

Question

I'm using OpenLayers to display a map and to provide some drawing features. I also added two SelectFeatures to the vector layer I want to draw on. One for highlighting a drawn feature by hover it and one for selecting a feature by clicking on it.
I used this example to realize this.

The problem is, that this solution doesn't really work (even in the given example).
If I draw a new feature I can highlight it by putting the cursor on it but can't select it with a click. (Same in the example, the given features work fine, but after drawing a new one the select-by-click function doesn't react anymore)

Is there any alternative solution to realize this except the official example?

此示例在 4个月前进行了修改 ，由于描述的混乱，排除了编辑工具栏。

Answer 2

I was able to get something like this working. You need to activate the controls in a specific order:

highlightControl.activate();
selectControl.activate();
dragControl.activate();

Hover events aren't handled by the Drag and Pan Controller, so they try the select controller, which doesn't use them either, passing them up to the highlight controller. Similarly, click events aren't handled by the drag controller, but are handled by the select controller. Finally, drag events are dealt with by the drag controller. The last to be activated is the first to be "consulted".
