Create Text Box Dynamically
Hi, I want to create 'n' text box dynamically, the 'n' should comes from database Whether 'n' should be 3 or 4 or 12 it will be vary dynamically and decided by the end user. Is it possible to create 'n' text Box dynamically or at run time with struts2, Also how text box can be accessed because i don't know the name! suppose I want to access a specific text box? Thanks,Vinodh
I cant load Select Box dynamically
Hi, Thanks for reply Mr.Michal Ciasnocha... I cant understand i need some
explanation, i don't know how to set in a attribute.
Also I can't copy the result returned from Data_Conn.load_country() to
another list or array list. only chance is to use Data_Conn.load_country()
as a original.
if you know please do some modification on action page and paste as reply.
Thanks in advance.

Hi,
in class CountryAction you need assign retreived values from database to
countryList attribute, not list (you have in jsp ... list=countryList
...).
