Problem with DropDown List and ValueChange

Question

Hi,
I have the following problem (I use NetBeans 6.1): I have a page, made with the Visual Web Designer, where there is a DropDown List component. The expected behaviour is once I select an item from the dropdown list, something (depending on the item I clicked) appears or happens (so, without any submit button or action link).
This is the code I have at the moment:
JSP (Pagina1.jsp):
<h:selectOneMenu binding="#{Pagina1.dataTypeDropDown}" id="dataTypeDropDown" immediate="true" onchange="return getSearchFields(this);" style="height: 24px; left: 192px; top: 24px; position: absolute; width: 744px" valueChangeListener="#{Pagina1.dataTypeDropDown_processValueChange}">
    <f:selectItems binding="#{Pagina1.dropdown1SelectItems}" id="dropdown1SelectItems" value="#{Pagina1.dropdown1DefaultItems}"/>
</h:selectOneMenu>
Bean (Pagina1.java):
public void dataTypeDropDown_processValueChange(ValueChangeEvent vce)
    String selectedValue = (String)vce.getNewValue();
    System.out.println(selectedValue);    // nothing happens!
    System.out.println("Hello");    // nothing happens!
[...]My problem is that, whenever I select an item form the dropdown list, ehm... nothing happens.
What could I do? Isn't that a kind of "change of value"? JavaScript events work fine, but no way with the ValueChange.
And please consider that I'd like to obtain the same result with both Standard Components and Woodstock Components.
Any help would be greatly appreciated!
Thanks!

Answer 1

try adding "*this.form.submit();*" to your on change attribute of select menu.
Your on change will look like onchange="return getSearchFields(this);this.form.submit();"
This should work.
