problem description

in German keyboard layout, entering a comma , requires pressing the shfit key. Here I simulate this case with a colon :.
( The document mentions that we don't support a colon. http://books.zkoss.org/wiki/ZK_Component_Reference/Input/Chosenbox#Properties)

steps to reproduce

1. run the zul below

   <zk>
   <zscript><![CDATA[
           ListModelList model = new ListModelList(Locale.getAvailableLocales());
   ]]></zscript>
   <chosenbox separator=":" model="${model}" width="200px"></chosenbox>
   </zk>
   

2. use : to choose an item

result

We actually input a colon instead of choosing an item. It doesn't work because inputing : requires pressing the shift key.
