Hello,

I need some urgent help.

I'm just trying to use an JSP which will display an list populated in the action class. Here is my code. The same code is using in the real project. But in my PoC setup, always I'm getting the following error

tag 'select', field 'list': The requested list key 'empList' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]
at org.apache.struts2.components.Component.fieldError(Component.java:230)
at org.apache.struts2.components.Component.findValue(Component.java:351)
at org.apache.struts2.components.ListUIBean.evaluateExtraParams(ListUIBean.java:80)
at org.apache.struts2.components.Select.evaluateExtraParams(Select.java:105)
at org.apache.struts2.components.UIBean.evaluateParams(UIBean.java:856)

I have spend my whole day, to find out the problem, but still in dark.

Here is my JSP

Please read this FAQ entry. What's "PoC"? How are you accessing the page?

Thanks for your response David.
PoC is Proof Of Concept...my intension is to develop some other functionality and these should be the basic feature.. .and for your second question, I'm calling the page by http://localhost:8080/StrutsTabs/quizAjax!input.action...
Thanks

There's nothing in the list. The execute() method isn't called when you call the input() method--input() is.

This is one usecase for the Preparable interface.

Hello David,

Sorry for delayed response.I was out of station. Thanks for your feedback. Ya it was the problem and now it has been rectified.

Do you have any knowladge whether S2 checkbox has any bug? My problem in some of the system , the checkbox is working perfectly but in some of the system it is not.

Let me to explain the problem , the action class is configured to execute some special functon while the check will be checked, but I was astonised in some of the system , the action calss can not detect if the check box is checked.

I'm using Struts 1.0.12 and Tomcat 5.5.27.

Thanks again
