Question

For copy value to next action used following syntax

<s:hidden name="formRow.value" value="%{formRow.value}" />

What syntax should I use to copy whole array of objects with thier fields? I’ve tried such apprach:

<s:iterator var="entry" value="%{formRow.myArray}" status="stat">
    <s:hidden name="formRow.myArray[#stat.index].val1" value="%{entry.val1}"/>
    <s:hidden name="formRow.myArray[#stat.index].val2" value="%{entry.val2}"/>
</s:iterator>

but while form submitting, formRow.myArray still empty..

Answer 1

In your case value attribute is not actually needed, name is enough. Try this:

<s:iterator value="formRow.myArray" status="stat">
   <s:hidden name="formRow.myArray[%{#stat.index}].val1"/>
   <s:hidden name="formRow.myArray[%{#stat.index}].val2"/>
</s:iterator>
