Well, first off I sincerely apologize for using an improper naming
technique I'm totally new to coding in itself :s. As Suggested ,Ive changed
the return value of dt_oid and objid across the code . And im trying to
set it through the jsp by modifying the select tag .
as below.
<s:select
headerKey="-1" headerValue="--Select--"
list="dtList"
listValue="listbean.code"
listValue="listbean.dt_oid"
name="listbean.domainType"
onchange="function1(this)"
/>.
I'm not sure how far this is effective though as the drop down form the jsp
is empty . Even though the source shows the various options.
Also I dont understand what you mean by creating the ids,could you please
explain?
