re-populating dropdown boxes
I've just started a project on struts and i'm facing a problem while doing
validations in ActionForm. Say if i have a textbox and a dynamically
generated dropdown box in my page and both the fields are mandatory. I
select a value in the dropdown but do not enter anything in the textfield.
The ActionForm performs the validation and returns an ActionError. But when
i'm repopulating the screen i do not have all the dropdown values in my
FormBean (only the selected value is sent as part of request). How do i
handle this situation if i should not make any database calls from the JSP.
I'm sure that this is a standard problem and most of you guys would've faced
this. It would be great if someone can let me know what is the
right/approppriate way to handle this.
Thanks in advance,
Gana

Hi,
I had the same problem and worked around it. Works just fine.
I had 2 drop-downs for country list and state list in an Employee Update
page. I traversed to this page from the EmployeeMaster page which had a
listing of all the employees in a company.. To come to this page I used
"EditEmployeeAction" servlet and for Saving values "SaveEmployeeAction".
when I change the country i should get the corresponding state list.
I used "submit" to a ActionServlet which I was using for "Save" on change of
country list drop-down. I got a different reference to the drop-down event
(say: if(save==null and cancel==null) and called another mapping.findForward.
This is the same forward used in "EditEmployeeAction" which I used to come to
the Update page.In the ActionForm, in the reset method I took off the null
for the Vector for country and state list and repopulated the lists. That is
all!.
PS-In case U need the source code clipping let me know.
