How to handle the list dynamically in struts inside logic:iterate tag

I am having following code in JSP
<table>
<tr>
<logic:iterate name="loginForm" id="inutParams" property="inutParams" indexId="i">
<tr>
<td><bean:write name="inutParams"/>:</td>

<td><html:text size="50" name="loginForm" property="inutParamsvalues"/></td>
</tr>
</logic:iterate>
<td>

</td>
</tr>
</table>


my struts config with dyna form is:
<form-bean name="loginForm" type="org.apache.struts.validator.DynaValidatorFor m">
<form-property name="username" type="java.lang.String" />
<form-property name="password" type="java.lang.String" />
<form-property name="dbNameList" type="java.util.List" />
<form-property name="firstname" type="java.lang.String" />
<form-property name="lastname" type="java.lang.String" />
<form-property name="gettingstart" type="java.lang.String" />
<form-property name="errormsg" type="java.lang.String" />
<form-property name="region" type="java.lang.String" />
<form-property name="spname" type="java.lang.String" />
<form-property name="query" type="java.lang.String" />
<form-property name="headerList" type="java.util.List" />
<form-property name="finalList" type="java.util.List" />
<form-property name="recordList" type="java.util.List" />
<form-property name="errorMsg" type="java.lang.String" />
<form-property name="spDetails" type="java.util.List" />
<form-property name="inutParams" type="java.util.List" />
<form-property name="inutParamsvalues" type="java.util.List" />

</form-bean>


In my action I wish to take the values from list named inutParamsvalues.

DynaValidatorForm bean = (DynaValidatorForm) form;
inputParamVal = (List) bean.get("inutParamsvalues");
System.out.println("-------Size-----"+inputParamVal.size());
for(int i=0;i<inputParamVal.size();i++)
{
System.out.println("In UserAction::fetchSP() ::inputParamVal="+inputParamVal.get(i));
} 


I am getting the inputParamVal list in action as null.Instead It should give the values entered by user in those many textfields.

pls anyone have any Idea.
Pls note that the list inutParams doesn't have exact number of values...It may vary from 1 to 15.
