vaadin - BeanItem not updating associated Field more than one, when changing property by hand -

-

i'm scratching head, trying work out why beanitem's property isn't updating component field's value - more once :(.

class mycomponent extends customcomponent {     textfield firstnames     beanitem<myobject> bean = new beanitem<myobject>(new myobject())      mycomponent() {         layout layout = new formlayout()         setcompositionroot(layout)          firstnames = new textfield("first names")         layout.addcomponent(firstnames)          fieldgroup binder = new fieldgroup(bean)         binder.bindmemberfields(this)     }      void setfromaccount(myobject newobject) {         bean.getitemproperty("firstnames").setvalue(newobject.firstnames)     } }

the first time call setfromaccount value of firstnames text field updated on screen. second time isn't, , first value persists.

does know what's going on? thought whenever set value on underlying property updated through internal listeners. why happening first time?
