javascript and STRUTS

["Eric C. Hein" <gr...@mindspring.com>]

Background:
In my form I have a field "city" that the user selects from a drop down list.  The city dropdown is initially setup to have one option that cues the user to select a county first (-1, select county first).  After the user selects a county the options list for city is then set to a javascript array of cities that are in the selected county. 

Problem:
After registering the user can edit his/her profile.  I'm having no trouble getting the county from the db to the <html:select> tag, but the city tag is not working.  When I call the javascript function that loads the cities I do get the correct cities (those corresponding to the county that came from the db).  I cannot however, set the correct value of the city field because the bean property "city" has already been overwritten by "-1".  

Is there anyway to capture the value of the bean before it is overwritten?

Thanks
- Eric

Rick,
Thanks.  The problem with setting a hidden field was that after the form is
created the bean property was already overwritten.  What I needed to do was
set a javascript variable:
    theCity = new String(<bean:write name="beanName" property="city">);
This gets done before the form is created.

Rgds,
Eric

Since your using javascript coulnd't you set a hidden field
"oldValue" that you can set before you do any overwriting? Then you
would have access to the old value in whatever 'new' stuff you are
doing.
