So it is possible to send a list with another list ( 2d list) to a servlet? My
sources follows:
<s:form action="do-translate-document" cssClass="formtable"
method="POST">
<s:iterator value="contentList">
<tr><td>
<p class="expression">
<s:property value="expression" />
</p>
<s:hidden name="content.id"/>
<textarea
name="contentList.content.translations.translation"> </textarea>
<s:iterator value="translations">
<p class="translation"><s:property value="translation" /></p>
</s:iterator>
</td></tr>
</s:iterator>
<s:submit />
</s:form>
Content.java
**********
public class Content {
private Long id;
private String expression;
private List<Translation> translations;
public void setExpression(String expression)
{
this.expression = expression;
}
public String getExpression() {
return expression;
}
public void setTranslations(List<Translation> translation) {
this.translations = translation;
}
public List<Translation> getTranslations() {
if(translations == null)
translations = new ArrayList<Translation>();
return this.translations;
}
public void addTranslation(Translation translation){
getTranslations().add(translation);
}
public void setId(Long id) {
this.id = id;
}
public Long getId() {
return id;
}
}
Translation.java
********
public class Translation {
private Long id;
private Content expression;
private String translation;
public Translation(){}
public Translation(String s){
translation = s;
}
public void setId(Long id) {
this.id = id;
}
public
Long getId() {
return id;
}
public void setExpression(Content expression) {
this.expression = expression;
}
public Content getExpression() {

}
public void setTranslation(String translation) {
this.translation = translation;

without looking at the Action class and the struts-config.xml it is difficult
to determine the failure to submit problem ..i did notice
1)contentList.content.translations.translation whwre name is not camelcase but
lowercase and does not include package identitifer e.g.
name="name"
2)you endtag textarea to exclude <s:iterator value="translations">..thus
textarea is one giant block of text without any relationship
to any of the other declared properties
3)the declared iterator <s:iterator value="translations"> has no knowledge or
association with previous iterator <s:iterator value="translations"> and does
not reflect the current state of the iterator e.g.:
<!-- this example pulls from collection leftSideCartoonCharacters and the
property will output the count (and the top property) -->
<s:iterator value="leftSideCartoonCharacters"
status="stat">
<s:property value="%{#stat.count}" />.<s:property value="top"
/>
</s:iterator>
?
difficult to say whats going on without seeing your action class and
struts-config.xml
