Question

Hallo everyone i’m trying to use the initbinder annotations in order to match the values i receive from a multiply list box.The values from the list box are String values.Iinitially i did it with the following way just to match only one choice(i didn’t add the multiply choice yet) and it works perfectly fine. The code is the following:

At the controller i have this:

 @InitBinder 
public void initBinderResearch(WebDataBinder b) {

    b.registerCustomEditor(Research.class, new ResearchEditor());

}

At the debuging i can see that the binding of the research_area values is not successful.But i don’t take any exception or error.Can anyone tell me what i’m doing wrong and this is not working?

Answer 1

You can’t override PropertyEditor.setAsText(List<String> text) because it not exists in parent class and WebDataBinder will not use this method to make string to object conversions.

If you register your original ResearchEditor and change the property from type Research to type List<Research> in your backing form model, the WebDataBinder will convert thems.
