Re: html:select default value in Struts

The workflow looks like this:

           BuildList.do
page1.jsp ---------------> page2.jsp

BuildListAction is called, and builds a selection list in page2.jsp
with data retrieved from a database, as you guessed.

            GetData.do
page2.jsp ---------------> page2.jsp (updated)

page2.jsp contains GetDataForm with the <html:select> valued to
"Choose one". When this form is submitted, page2.jsp is updated by
GetDataAction with other data retrieved from the database.
And I'd like the <html:select> staying with the value I've just
selected.

When I go back to page1.jsp and then return to page2.jsp,
<html:select> must be valued to "Choose one".
