Problem in showing nested lists in jsp page

[dhaval tamboli]

Hi,

I am using struts2.

My design is like I have Araaylist which has another arraylist in it.

i.e.
In My action class I do have

 private List<GenericModel> previewList;

and GenericModel contains

private int Question_ID;
private String Question_Name;
private String Question_Type;
private List<OptionModel> oList = new ArrayList<OptionModel>();

and OptionModel contains

private int Option_ID;
private String Option;

I have eneterd all information correctly but I am not able to show them on JSP in way I want.

my JSP Page contains

<s:iterator value="previewList" var="list">
	
      <s:iterator value="#list.oList" var="opt">
	       <s:property value="#opt.Option" /> 
	</s:iterator>
	   
	<tr>
		   <s:property value="Question_Name" /> 
        </tr>
      	<tr>
      	  
      	   <s:property value="Question_Type" />
      	  
        </tr>
        
	</s:iterator> 

I want to show all information contained in previewList, I can see Question_Name and other but I am not sure how to access information from OptionModel list.
Above code is not working (just the oList part) I am not able to see its contents.

please give your thoughts to solve my problem

Thanks,
Dhaval

The s:iterator tag pushes the iterated element on the top of the value stack, so this code should work

<s:iterator value="previewList" var="list">
	<s:iterator value="oList">
		<s:property value="option" /> 
	</s:iterator>
	<tr>
		<s:property value="Question_Name" /> 
	</tr>
	<tr>
		<s:property value="Question_Type" />      	  
	</tr>
</s:iterator>

Hi Ankit,

I know I am doing right, but I am not able to get anything in jsp. However I tried to see in action class if I am loading it right or if there is any other problem but there I can see each elements in order by get methods.

Here in JSP page, I tried to see its size but even that also not showing anything.

I tried

<s:property value="oList.size()" /> 

but still nothing. I dont know what to do next
please help me

Thanks
Dhaval
