Question

Instead of just displaying list values using <s:property/>, i need to display it in textarea.The reason why i am doing this is <s:property/> does not have “name” attribute in order to submit the values to the action class. Is there any way to do that.I wrote down piece fo code below to make it clear so that you can understand my requirement though it is wrong.Please help me.

<s:iterator value="map"   status="stat">

<s:textarea value="<s:property/>" />    

</s:iterator>

Answer 1

As Jagan said, assume that map is java.util.List

<s:iterator value="map" status="stat">
    <s:textarea value="%{top}" />
</s:iterator>

or

<s:iterator value="map" status="stat">
    <s:textarea>
        <s:param name="value">
            <s:property/>
        </s:param>
    </s:textarea>
</s:iterator>

or

<s:iterator value="map" status="stat">
    <s:textarea>
        <s:param name="value">
            ${top}
        </s:param>
    </s:textarea>
</s:iterator>

@Jagan : if it is map how to do this ?

Assume map is java.util.Map

<s:iterator value="map" status="stat">
    <s:textarea value="%{key}" />
    <!-- or -->
    <s:textarea value="%{value}" />
</s:iterator>

IteratorComponent

if (value == null && begin == null && end == null) {
    value = "top";
}

top is not a attribute of iterator and not a keyword of OGNL. (I may be wrong)

top : top of Stack / element of the current iteration

e.g.

<s:property value="top" />

or

<s:property value="[0].top" />
