Programmatically selecting Item in drop down

Question

I want to Programmatically select an item in a dropdown when the page is loaded. I am using the following code:
<h:selectOneMenu binding="#{CatByLocTrend.predefinedQueryDropdown}" id="predefinedQueryDropdown"
style="height: 21px; width: 133px; font-family: Verdana,Arial,Helvetica,sans-serif; font-size: 10px" valueChangeListener="#{CatByLocTrend.predefinedQueryDropdown_processValueChange}">
<f:selectItems binding="#{CatByLocTrend.predefinedQueryDropdownSelectItems}"
id="predefinedQueryDropdownSelectItems" value="#{CatByLocTrend.predefinedQueryDropdownDefaultItems}"/>
</h:selectOneMenu>
I use the following to select the item after the default values have been loaded:
predefinedQueryDropdown.setValue(new Integer(2));
predefinedQueryDropdownSelectItems.setValue("Top3Sales");
Neither of these work. How do I programmatically select the value?

Answer 1

I have this working.
Following is some code snippets:
JSP:
<h:selectOneMenu binding="#{Admin$AdminEscalationList.uiSelOneMnuMgrList}" id="dropdown2"
                            style="left: 443px; top: 349px; position: absolute; width: 186px" value="#{Admin$AdminEscalationList.currMgrSelection}">
                            <f:selectItems id="dropdown2SelectItems" value="#{Admin$AdminEscalationList.escalationContntMgrs}"/>
</h:selectOneMenu>Now is the Code behind it:
Java:
    private UISelectOne uiSelOneMnuMgrList  =  new UISelectOne();
    public UISelectOne getUiSelOneMnuMgrList()
        return(uiSelOneMnuMgrList);
    public void setUiSelOneMnuMgrList(UISelectOne oNewVal)
        uiSelOneMnuMgrList      =  oNewVal;
    private int m_nMgrId        =  0;
    public Integer  getCurrMgrSelection()
        return(new Integer(m_nMgrId));
    public void  setCurrMgrSelection(Integer strMgrSelection)
        try
            m_nMgrId            =  strMgrSelection.intValue();
        catch(Exception ex)
// Now is the function that pre-set the selection of the list.
// Call the below function in whereever you want to set the preselection.
uiSelOneMnuMgrList.setValue( getCurrMgrSelection());Of course, I am calling the setCurrMgrSelection() before calling the
uiSelOneMenuMgrList.setValue() function.
Let me know if any of you have any trouble with this.
