Try the square brackets again.

Try: value="%{name}"
That gets the value into the textbox, but when I submit the form, I get either
nothing in the action (square brackets) or an exception (using curly brackets):
<s:iterator value="beanList" var="bean">
<s:textfield theme="simple" name="beanList(%{#bean.id}).name" value="%{name}"
/><br>
</s:iterator>
All my save action does is print out the array.
public class TestAction implements Action {
private static Logger log = Logger.getLogger(TestAction.class);
// note: getters/setters/execute method already posted removed
public String save(){
log.debug("save: beanList size: "+beanList.size());
for (int i = 0; i < beanList.size(); i++){
log.debug(beanList.get(i));
}
return SUCCESS;
}
}
The SUCCESS result is mapped to a blank JSP:
<action name="saveTest" method="save"
class="gmi.action.test.TestAction">
<result name="success">/test2.jsp</result>
</action>
The exception from the curly-brace version is:

Is this a problem with type conversion?
