java zk mvvm clear datebox and do @command -

i'm trying make filter datebox. when no date inserted, not added query. when date inserted, counts date on.

this works good, stupid little problem have have button clearing date. or @command(...) , set mine queryobject.date null, witch renew mine search correct date still in datebox. (i don't want use autowired datebox)

or searchbegindate.settext(null) , text gone mine list doesn't refresh.

what option have both?

edit : sample code of project.

 <datebox id="searchbegindate" value="@bind(vm.loggingvmqueryobject.begindate)" onok="@command('filter')" />  <button onclick="searchbegindate.settext(null);vm.loggingvmqueryobject.setbegindate(null)"  image="/img/delete.png" /> 

this whiping of datebox list isn't refreshed.

<datebox id="searchbegindate" value="@bind(vm.loggingvmqueryobject.begindate)" onok="@command('filter')" /> <button onclick="@command('clearbegindate')"  image="/img/delete.png" /> 

this refresh list correct, in code loggingvmqueryobject.begindate set null datebox still showing last date set.

greetz chill.

you show me code, show solution ;)

in zul

<datebox id="searchbegindate" value="@bind(vm.loggingvmqueryobject.begindate)" onok="@command('filter')" /> <button onclick="@command('clearbegindate', date = searchbegindate)"  image="/img/delete.png" /> 

in java

public void clearbegindate(@bindingparam("date")datebox date){ //your other code here date.settext(null);  }
