Logic Tag Question

["Kalcevich, Daniel" <dk...@firstam.com>]

I have the following:

 

-          An ArrayList<LabelValueBean> in the ServletContext called
"timezones"

-          A Form Bean in the request scope called "accountProfileForm"

 

I want to be able to loop through the values in the "timezones"
attribute and compate the "value" to the value of the "timeZone" in the
"accountProfileForm".  Here is what I am trying:

 

<logic:iterate id="timeZones" collection="timezones" property="value">

      <logic:equal name="accountProfileForm" property="timeZone"
value="timeZones.value">

            <bean:write name="timeZones" property="label"/>

      </logic:equal>

</logic:iterate>

 

I get the following error:

 

12:16:59,031 ERROR [action]:253 - Servlet.service() for servlet action
threw exception

javax.servlet.jsp.JspException: ServletException in
'/jsp/templates/tab_content_template.jsp': ServletException in
'/jsp/account/account_profile_form.jsp': Cannot create iterator for this
collection

      at
org.apache.struts.taglib.tiles.InsertTag$InsertHandler.doEndTag(InsertTa
g.java:923)

 

 

 

Can someone point me in the right direction or let me know what is wrong
with the above?  Thanks.

 

Daniel

If I am not mistaking you will use either the collection or the property
attribute but not both.
http://struts.apache.org/struts-taglib/tagreference-struts-logic.html#logic:iterate

For each iteration of the loop you should be able to compare the value of the
id property in you logic:equal tag to the forms value by saying
<logic:iterate id="tz" collection="timezones">
  <logic:equal name="accountProfileForm" property="timeZone" value="${tz}">
    //do something
  </logic:equal>
</logic:iterate>

It looks like a Map would be a better choice than an
ArrayList<LabelValueBean>.  Can you change it?  Then you could just use

[untested]
   <c:out value="${timeZones[accountProfileForm.timeZone]}"/>
