AW: Problems with ValueChangeEvent and ValueBinding
I meant the Binding attribute, but I have already achieved it with
setSubmittedValue().

Andy, when you say ValueBinding and Binding do you mean the
binding attribute or the value attribute?

If I try to set the value with the appropriate setter method, just nothing

Do I have to set the value in another way?

Betreff:Problems with ValueChangeEvent and ValueBinding
Hi all!
In my application I have a inputText Component with a ValueChangeEvent.
The ValueChangeMethod starts a Database query and if some data is found,
then the founded records are written into other inputText Components on the
mask.
The problem now is, that if I add a ValueBinding attribute to this other
inputText fields, the new data from the query isn't written into the fields.
If I remove the Valuebinding everything works...
How can I overcome this problem?
Here my jsp with two InputText Fields
t:htmlTag value=td rendered=#{showTags.showLfnr}
h:inputText binding=#{beziehungsDto.ITlfnr} id=lfnr
value=#{beziehungsDto.lfnr} styleClass=mustfield
required=true
size=35 rendered=#{showTags.showLfnr} immediate=true
valueChangeListener=#{querySelectHelper.selectSamData}
onchange=submit()
f:validateLength maximum=35/f:validateLength
/h:inputText
/t:htmlTag
In this second field some data should be written. If I remove the binding
attribute, it works, if I leave it, the field isn't updated...
t:htmlTag value=td
h:inputText binding=#{beziehungsDto.ITpartnername}
id=partnernameneu value=#{beziehungsDto.namepartner}
styleClass=mustfield required=true size=35
f:validateLength maximum=35/f:validateLength
/h:inputText
/t:htmlTag
Here is the ValueChangeMethod:
public void selectSamData(ValueChangeEvent event)
{
beziehungsDto =
(BeziehungDto)FacesUtil.getManagedBean(beziehungsDto);
qh =
(QueryHelper)FacesUtil.getManagedBean(queryHelper);
Session session = HibernateSAMUtil.currentSession();
Transaction tx = null;
try {
tx = session.beginTransaction();
String sqlstring = Select a.firmNr, a.firmNamKurz,
a.bdtKndNr, +
a.lfvUebArt, a.sfDunsNr from
Eklist a where a.firmNr=:liefnr;
Query q =session.createQuery(sqlstring);
q.setString(liefnr, (String)event.getNewValue());
Iterator it = q.list().iterator();
while(it.hasNext())
{
Object[] row = (Object[])it.next();
//beziehungsDto.setNamepartner((String)row[1]);
beziehungsDto.getITpartnername().setValue((String)row[1]);
beziehungsDto.setNamepartner((String)row[1]);
...
}
}
String viewId = /popupAddBeziehung.jsp;
FacesContext context =
FacesContext.getCurrentInstance();
UIViewRoot view =
context.getApplication().getViewHandler()
.createView(context, viewId);
view.setViewId(viewId);
context.setViewRoot(view);
context.renderResponse();
tx.commit();
}
catch (Exception ex) {
if (tx != null)
tx.rollback();
MessageUtils.addMessage(FacesMessage.SEVERITY_WARN,
errorListDataForAdminDB, null,
context);// TODO
ex.printStackTrace();
}
finally {
