There is a similar question on this site asking for how to set the default vaule for an HTML object.
This relies on setting a "value" tag for an individually-listed <option>, but I am using an optionsCollection, with a pre-set list of options. 
<html:select property="optionsList">
    <html:optionsCollection name="lutOptions"/>
</html:select>
I tried indicating the desired option to be selected, but it doesn't appear to work.  Instead, it just creates a new option for the list at the bottom.  
<option selected="selected">desired option</option>
How do I set one of the options from the lutOptions list to be the default option for my optionsCollection object?
