选择项目后，Flex可搜索组合框中没有显示边框

Question

Just after choosing an item in Searchable ComboBox, the border of the combobox is not visible. Then on blur of the combox the border is again visible. It's really strange feeling. Please help me out here.

<ComboBox id="studyId" 
     dataProvider="{employeeList}" 
/>

Here employeeList is an ArrayList collection where employee objects are there. Note: I cannot provide/change any css/style for this combobox. Please let me know if there is any other way in mxml part or Action Script.

The combobox looks like the image.

Answer 1

From what I see, its because of using application wide theme style since there is no skin associated with this combobox component.

The best way to handle this is by creating custom skin in Flex to override any style you need.

Hope this helps.
