selectonemenuitem problems Value is not a valid option
Hi,
I am working with two selectOneListBox in jsf
If I selected one item in first list box the corresponding values(from
the database (setting that values to preparedstatement))
must displayed in second list box
For that I used value change listener .
When I am submitting this form I am getting an error
cpuids: Value is not a valid option.
This is my code.
This is jsp code.
h:outputText value=SelectHOST //th
h:panelGroup
h:selectOneMenu id=hostids
value=#{HRselforeachcpuanduser.host}
valueChangeListener=#{HRselforeachcpuanduser.hostSelection}
onchange=submit();immediate=true required=true
f:selectItem itemValue= itemLabel=/
f:selectItems
value=#{HRselforeachcpuanduser.hosts}/
/h:selectOneMenu
h:message for=hostids style=color:red/
/h:panelGroup br
h:outputText value=SelectCPU /
h:panelGroup
h:selectOneMenu id=cpuids
value=#{HRselforeachcpuanduser.cpuid}
f:selectItems
value=#{HRselforeachcpuanduser.cpuids}/
/h:selectOneMenu
h:message for=cpuids style=color:red/
/h:panelGroup
// this is backing bean code
Corresponding java code
// this is for value change listener
public void hostSelection(ValueChangeEvent e) {
FacesContext context = FacesContext.getCurrentInstance();
hostid=(String) e.getNewValue();
getCpuids();
context.renderResponse();
}
//this is for host select
public Map getHosts(){
try{
openConnection();
selhostnames=new HashMap();
String str=select distinct hostid from system_cpu;
st=con.createStatement();
rs=st.executeQuery(str);
while(rs.next()){
hostname=rs.getString(hostid);
System.out.println(hostname);
selhostnames.put(hostname,hostname);
}
return selhostnames;
}
public String getHost(){
return hostselected;
}
public void setHost(String hostselected){
this.hostselected = hostselected;
}
//this is for cpu selection
public Map getCpuids(){
try{
if(hostid==null){
System.out.println(if it is null); // imp note
return selcpunames;
}
openConnection();
String str=select distinct cpuid from system_cpu where hostid=?;
System.out.println(setting cpuids from host);
ps=con.prepareStatement(str);
ps.setString(1,hostid);
ps.execute();
rs=ps.getResultSet();
while(rs.next()){
cpuname=rs.getString(cpuid);
System.out.println(cpuname);
selcpunames.put(cpuname,cpuname);
}
return selcpunames;
}
public void setCpuid(String cpuid){
this.cpuid=cpuid;
}
public String getCpuid(){
return cpuid;
}
When I am running
If its null//in tomcat
And
cpuids: Value is not a valid option.
What is the problem with my code please tell and what to change
With regards

Re: selectonemenuitem problems Value is not a valid option
Hi,
the value of f:selectItems must be a array of SelectItem.
you shoud have:
public SelectItem[] getHosts() {
...
}

RE: selectonemenuitem problems Value is not a valid option
Have you tried the selectManyPicklist from the sandbox? Works like a charm!
