In my form, I have a select box which get the option value populated from
database.
But when validation fail and return to input page (jsp page), I get the
error where the option value cannot be found.
I know this is because the method (e.g search) is not called to retrieve
data from database. I tried to use "chain" result type to forward back to
the main action (e.g list) but I get "Infinite recursion detected" error.
May I know what is the best way to return to input page and at the sametime
retrieve data for the select box?
I don't want to store the option value in http session coz this way I need
to find a way to clean up unuse option value and might get problem is user
spore multiple tab on browser.
Appreciate is someone can give some guidelines. Thanks.
The following is my config and code.
struts.xml
-----------------
<action name="*_search" class="{1}Action" method="list">
<result name="success">/pages/{1}_search.jsp</result>
<result name="input">/pages/{1}_search.jsp</result>
<result name="cancel" type="redirect">welcome.html</result>
</action>
Sample_search.jsp
-----------------
<s:form>
<s:select name="user.country"
label="%{getText('user.country')}"
list="countryOptions"
headerKey="-1"
headerValue="%{getText('messages.select')}"/>
<s:submit key="buttons.search" method="search" theme="simple"/>
<s:submit key="buttons.cancel" method="cancel" theme="simple"/>
</s:form>
SampleAction
-----------------
public class SampleAction extends ActionSupport {
....
@SkipValidation
public String list() throws Exception {
this.countryOptions = lookupManager.getCountries();
return SUCCESS;
}
public String search() throws Exception {
List<?> results = userManager.findByValueBean(user);
this.listHolder = new PagedListHolder(results);
return SUCCESS;
}
....
}
