s:iterator with collection of Object array

Question

I have a ArrayList which contains a list of Object array Eg: new Object ['a','b','c']

The list is a member variable of data object.

Now, how can I access each 3 element data while iterating it in the s:iterator tag loop

<s:iterator value="data.list" status="cnt" var="searchList">

  <s:property value="searchList[0]"/>
  <s:property value="searchList[1]"/>
  <s:property value="searchList[2]"/>

</s:iterator>

I tried above code, but it displayed nothing.

You are just missing `#` in front of `searchList` in `` tag. (e.g. ``). — Aleksandr M, Apr 23 '14 at 07:33

This won't get elements from the array. – Aleksandr M Apr 23 '14 at 07:32

Use the property directly by the index

<s:iterator value="data.list" status="cnt" var="searchList">
  <s:iterator begin="0" end="data.list.length" var="idx">    
    <s:property value="[1].data.list[%{#idx}]}"/>
  </s:iterator>    
</s:iterator>

Because you are not iterating list. – Aleksandr M Apr 23 '14 at 07:39
the list has elements, so it's iterating, why not? – Roman C Apr 23 '14 at 07:41
Well yes list is iterating. :) But you are not getting elements from list iteration. – Aleksandr M Apr 23 '14 at 07:46
Is this better? Why not getting? – Roman C Apr 23 '14 at 07:48
thanks roman and alek..by the way why # in needed? is it needed to be a OGNL to be work? Why value="data.list" in s:iterator doesnt need the #. This "data.list" is also OGNL right? – Harshana Apr 23 '14 at 07:51
@Harshana # is used to access context variables (directly) – Roman C Apr 23 '14 at 07:55
when i use i guess by default it prints the first element but how can i access the whole array object. For example suppose i need to assign the array object to it to a java scriplet variable. <%Object[] row = (Object[])%>; – Harshana Apr 23 '14 at 08:16
@Roman # is used to access context variables (directly). what you mean by directly? How come we can access here without the # – Harshana Apr 23 '14 at 08:19
It prints the *current* element reference pushed into the Value Stack. By directly I mean it will not *search* the value stack, without it the value stack is searching the whole stack. – Roman C Apr 23 '14 at 08:25
how can assign the array object directly to a scriplet? – Harshana Apr 23 '14 at 09:39
@Roman i try below and even return empty – Harshana Apr 23 '14 at 10:14
