Thanks, Mark, I tried "indexed" property, but it gives error msg, because it
is valid only inside of <logic:iterate> tag. My case is like:
------------------
<html:select property="deleteSubject" size="6" multiple="true">
<logic:iterate id="test" name="questionForm" property="subject"
scope="session">
<html:option value=""><bean:write name="test"/></html:option>
</logic:iterate>
</html:select>
------------------------
The key point is to repaly <html:option value=""> with something indexed.But
quote symbol is required. So the following wouldn't work:
-------------------------
<% String s = "test"; %>
<html:option value=s><bean:write name="test"/></html:option>
---------------------------
What else can I try?

Have you tried the "indexed" property?

Thanks, but how does struts work to assign a default value to a item? It
there any example for this? I can't find any good example on this.
Thanks,

i think you need to pass some kinda value through because http doesn't pass
through blanks...
struts has a mechanism that helps deal with this where selects default to on
or off or something...
or you could just assign a temporary value when the item is selected for
deletion..
hope this is helpful mark
