java - What is the different between using TextChangeEvent getText() and TextField getValue() in TextChangeListener -

-

i new vaadin, try filter out data on table. add textfield declared isocode , add textchangelistener it.

when use isocode.getvalue() value filter string, didn't work.

but when use textchangeevent event.gettext() value work perfectly. can explain me tell why?

final textfield isocode = new textfield();  isocode.setinputprompt("iso code");  isocode.addtextchangelistener(new textchangelistener(){     private static final long serialversionuid = 1l;     simplestringfilter filter = null;     @override     public void textchange(textchangeevent event) {          /**          * code not working          *         if(isocode.getvalue().trim().length() > 0){              filter = new simplestringfilter("iso code", event.gettext(),true, false);             appn0010form.removeallcontainerfilters();             appn0010form.addcontainerfilter(filter);         }         */           /**          * code working          */         if(event.gettext().trim().length() > 0){               filter = new simplestringfilter("iso code", event.gettext(),true, false);             appn0010form.removeallcontainerfilters();             appn0010form.addcontainerfilter(filter);         }      }   });

isocode.getvalue() gives value of textfield before binding latest value.

where event.gettext() gives value after binding latest value.

newly typed value bind after blur of textfield.
