portlet:param tag and sending String[]?

I see that the portlet aram tag has the ability to load a String value into it. What if I want to load in a String array - a list of values that was returned from an HTML select box for example. The odd thing is that there is support for String arrays in renderRequest and actionResponse (there are methods for getting and setting arrays of Strings). But portlet aram... nope?

Am I missing something obvious? I am thinking of using session attributes to do what I need in case I cannot the portlet param tag to pass values... is this standard design?

Thanks in advance.

Do you want to store the values returned from select box , i mean persist it. Can you elaborate your requirement. i can suggest you the best option.
