Setting selected with s:select tags

[Kartik Kumar]

Hi Struts gurus,

I am have an object level attribute that is selected from the s:select tag.

  <s:select key="search.criterion" name="searchCriterion"
      list="#{'': 'Select One', 'bean.attributeValue':'bean.attributeValue',
'abc':'abc'}"
      required="true" onchange="showSearchCriterionField()" />

If I want to set 'abc' to selected, then how do do that ? Any advice would
be welcome.

Thanks,

Kartik
