Auto fields liferay in custom portlet - liferay

Question

I have a doubt.
I have a main.jsp that includes another 2 jsp and a submit button. Both of them are part of a form.
The second one includes an auto field with a validator:
<div id="groupwork-fields" >
<div class="lfr-form-row lfr-form-row-inline">
<div class="row-fields">
<aui:input fieldParam='name' id="repetibleName" cssClass="full-size"
name="<%=AwardConstants.FIELD_OTHERS_NAME%>"
label='<%=AwardConstants.LABEL_NAME %>'
value="">
<aui:validator name="custom" errorMessage="fill-name">
function (val, fieldNode, ruleValue) {
var result = true;
var selector = document.getElementById("<portlet:namespace/>select-group").value;
if (selector == 1 && val === "") {
result = false;
}
return result;
}
</aui:validator>
</aui:input>
<aui:input cssClass="full-size"
id="email0" fieldParam='email0'
name="email0"
label='<%=AwardConstants.LABEL_EMAIL %>'
value="">
<aui:validator name="maxLength">100</aui:validator>
<aui:validator name="email"></aui:validator>
<aui:validator name="custom" errorMessage="fill-email">
function (val, fieldNode, ruleValue) {
var result = true;
var name = document.getElementById("<portlet:namespace/>name0").value;
if (name !== "" && val === "") {
result = false;
}
return result;
}
</aui:validator>
</aui:input>
</div>
</div>
</div>
After validating those fields and pressing the submit button goes to the next method:
public void saveAutofieldData(ActionRequest actionRequest, ActionResponse actionResponse) throws PortalException, SystemException {
String groupworkIndexes = actionRequest.getParameter("groupworkIndexes");
_log.info("::::::::::::::::groupworkIndexes:::::::::::::::::::::::" + groupworkIndexes);
/**
* Split the row index by comma
*/
String[] indexOfRows = groupworkIndexes.split(",");
_log.info("::::::::::::::::indexOfRows.length:::::::::::::::::::::::"+ indexOfRows.length);
for (int i = 0; i < indexOfRows.length; i++) {
String name = (actionRequest.getParameter("name"+ indexOfRows[i])).trim();
String email = (actionRequest.getParameter("email"+ indexOfRows[i])).trim();
_log.info("::::::::::::Name::::::::::::::" + name);
_log.info("::::::::::::Email::::::::::::::" + email);
}
}
The problem is when It tries to read: actionRequest.getParameter("groupworkIndexes"); I get null.
Thank you in advance

I finally got the solution.
All examples I've seen it have been with "actionRequest" to retrieve the data:
String groupworkIndexes = actionRequest.getParameter("groupworkIndexes");
String name = actionRequest.getParameter("name" + indexOfRows[i]));
But in my case i've used the following lines:
String name = (uploadPortletRequest.getParameter("name" + indexOfRows[i]));
String groupworkIndexes = (uploadPortletRequest.getParameter("groupworkIndexes"));
Not always we would get the prefered values with actionRequest
