Hello All,
I joined the mailing list today itself, so please let me know if am doing
anything wrong here. I am using struts2 for creating a web-application which
calls to a webservice(our API) and gets the results back. Basically in the
home page, there is a dropdown menu with 4 items in it. So whenever user
selects a particular list from the dropdown menu the form submits, and the
form changes. Each list in dropdown menu has its own form with its own
fields and those fields should change when the user selects different list
from dropdown menu. I am writing all this form code in a single jsp with
struts if , else tag. When ever the dropdown menu changes i am using java
script to submit to action. Now, the problem is i have 4 list items in the
dropdown menu. 3 list items works fine, when i select the 4t list item it
also works fine, but anything i select after 4t list item in the form
doesn't work. The dropdown doesn't even submit to the javascript and hence
the action is not called.
Each list item has its own form with its own list items. Suppose
i have 4 list items... insert, update, delete, truncate (just an example
names). If i select insert and submit works fine, if i select truncate the
page loads and populate the form for truncate, now after selecting truncate
if i select insert or update or delete the form is not able to populate. And
am getting following exception. I would highly appreciate your help. Hope to
get reply soon.
SEVERE: Servlet.service() for servlet jsp threw exception
tag 'select', field 'list', name 'selectedMetadataKey': The requested list
key 'metadataKey' could not be resolved as a
collection/array/map/enumeration/iterator type. Example: people or
people.{name} - [unknown location]
