Calling Action on form load
Hi all,
is it possible to call an action in struts2 everytime when the page get
loaded if yes how it is possible.
my problem is i am using <s:select> tag and using a list to pupulate this
drop down this list is coming from the action which i m calling before the
page is being displayed.
the folw is like this:
if usercall for this JSP page instaed to direct user directly to this page
i m calling an action which is preaparing a list for the <s:select> tag
and then it is forwarding the user to this page.
Till now eveything is working fine,but when on this page user is entering
some values in the fields and hitting the submitting button,exception is
being thrown which is saying that:
select', field 'list', name 'code': The requested list key 'ItemCode' could
not be resolved as a collection/array/map/enumeration/iterator type.
Example: people or people.{name} - [unknown location]
because i thik it is unable to call the action again which is returning the
list...is theer any way to call that action each time when user is
submitting the value..
any pointer in this regard will be much appriciated.

Hi Jane,
what i m doing in my action class i am putting the list in the session like
this
Map<String, ArrayList<String>> session = ActionContext.*getContext*
().getSession();
session.put("value",itemCode);
and in my jsp page i m trying to retrieving the values like this:
<s:select label="Select Code" cssClass="large" list="%{#session.value}"
name="code"
headerKey="1"
headerValue="-- Select Item Codet --"
list="ItemCode"
/>
but when ever i m hitting the submitt button it is giving me the exception
tag 'select', field 'list', name 'code': The requested list key 'ItemCode'
could not be resolved as a collection/array/map/enumeration/iterator type.
Example: people or people.{name} - [unknown location]
any suggestion in this regard??

Aum,
After you retrieve the list in your action, save it in session using
session.put("mySelectionList", list);
Then in your jsp, use the list in session for s:selection.
<s:select name="mysSelection" cssClass="large" value="selectedValue"
list="%{#session.mySelectionList}" listKey="value"
listValue="label" />
Hope this helps,
Jane

Aum,
I know what you are talking about. I end up putting all lists for
select tag in the session. Otherwise, you will have to reload the list
every time the form submits and when validation error happens. I'd like
to find out if there are other ways to get around too.

Hi all,
is it possible to call an action in struts2 everytime when the page get
loaded if yes how it is possible.
my problem is i am using <s:select> tag and using a list to pupulate
this
drop down this list is coming from the action which i m calling before
the
page is being displayed.
the folw is like this:
if usercall for this JSP page instaed to direct user directly to this
page
i m calling an action which is preaparing a list for the <s:select> tag
and then it is forwarding the user to this page.
Till now eveything is working fine,but when on this page user is
entering
some values in the fields and hitting the submitting button,exception is
being thrown which is saying that:
select', field 'list', name 'code': The requested list key 'ItemCode'
could
not be resolved as a collection/array/map/enumeration/iterator type.
Example: people or people.{name} - [unknown location]
because i thik it is unable to call the action again which is returning
the
list...is theer any way to call that action each time when user is
submitting the value..
any pointer in this regard will be much appriciated.
