SelectOneMenu and commandButtons

Question

Hi Iam using J2EE 1.4 and jsf1.0. I have the following code
<h:selectOneMenu id="groups" value="#{UserBean.selectedGroup}">
<f:selectItems value="#{UserBean.groupsList}"/>
</h:selectOneMenu>
<h:commandButton id="showGroupMembers" value="Show Members" action="#{UserBean.showGroupMembers}"/>
<!-- backing bean -->
groupsList.add(new SelectItem(groupName,groupName)); // groupName is a String
public ArrayList getGroupsList()
FacesContext.getCurrentInstance().addMessage(null,new FacesMessage("dd"));
return groupsList;
public void setGroupsList(ArrayList list)
try
groupsList = list;
catch(Exception e)
FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(e.getMessage()));
public SelectItem getSelectedGroup()
return selectedGroup;
//return new SelectItem((String)selectItemsList.get(0),(String)selectItemsList.get(0));
public void setSelectedGroup(SelectItem group)
try
selectedGroup = group;
catch(Exception e)
FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(e.getMessage()));
When I press the command buttons I get a message saying conversion error occured.But Iam not sure
either it is the conversion for selectedGroup or the ArrrayList . From other threads about this topic I learned that Strings should be ok to use with selectItem. Where am I going wrong.
thanx all for ur help

Hi sorry .
I was blindly following some example I found on the net. The selectedGroup must be String . Then everything works
sorry for the trouble
