Hi

Have a look at DropDownChoice.setNullValid() and .setRequired()

Hi, I am new in Wicket and am playing with different components.

I have a two dropdown lists. One is a list of countries, required field, 
controlling another list of states/provinces via 
AjaxFormComponentUpdatingBehavior.

The country list always has a blank (equivalent of Choose one) as the first 
option in the list. When I select different countries, the state/province list changes 
accordingly. However, when I change to the blank in the country list, the state list 
stops updating. I looked into it and found out that in this situation (required droopdown 
list) selecting blank makes Wicket issue a feedback message instead of calling 
AjaxFormComponentUpdatingBehavior#onUpdate, which is what I want.

What can I do to make Wicket the way I want?

Thanks!

Matt, I already did that.

DropDownChoice.setNullValid() makes Choose one always stay there.
I notice that DropDownChoice.setRequired() is the reason to generate the 
message and not get onUpdate called.

Thanks.

Hi

Yes, exactly, but why do you have it set to required at all in first 
place if you want to allow the empty selection too?
I dont think a DropDownChoice is required by default but if it is, try  
setRequired(false) ...

In my case, the field is required. I make it required by setRequired(true), but 
I want the blank/choose one is still there. 

Doable?
