How to pre-select in netui:select

Question

I am new to workshop. I need to use netui:select for a list box with multiple selection. I want to pre-select the listbox with several entries. I am wondering how to do this?

Cindy,
You can set multiple default values on a select tag by binding the
defaultValue attribute to a String[] or anything else (collection, etc)
that can be turned into an Iterator.
For example, here is how I modified Workshop's Sample Application
(specifically the "select multiple" example)
<netui:form action="submit">
<netui:select multiple="true" dataSource="{actionForm.selections}"
size="5" defaultValue="{pageInput.defaultValues}">
<netui:selectOption value="red" />
<netui:selectOption value="blue" />
<netui:selectOption value="green" />
<netui:selectOption value="yellow" />
<netui:selectOption value="orange" />
</netui:select>
<netui:button type="submit" value="Submit"/>
</netui:form>
here is the code from the controller showing the page flow variable
defaultValues being passed to the page as a page input in fhe Forward
contstructor.
private String[] defaultValues = {"green", "yellow"};
* @jpf:action
* @jpf:forward name="success" path="index.jsp"
protected Forward begin()
return new Forward("success", "defaultValues", defaultValues);
