missing hidden field

Hello expert ,
I have hidden field in a jsp
<input type="hidden" name="actionRequired"/>

I set the value in a javascript as below

if(validateSearchCriteria())
{
alert("passed validation criteria");
if(document.forms["limsRecordAdvancedSearchForm"].elements["useAltSearch"].checked == true)
document.forms["limsRecordAdvancedSearchForm"].elements["actionRequired"].value = "ALTERNATESEARCH";
/*else if(trimString(document.forms["limsRecordAdvancedSearchForm"].elements["recordNo"].value) != "")
document.forms["limsRecordAdvancedSearchForm"].elements["actionRequired"].value = "SINGLERECORD";*/
else
document.forms["limsRecordAdvancedSearchForm"].elements["actionRequired"].value ="ADVANCEDSEARCH";
alert("setting actionRequired as" +actionRequired");
document.forms["limsRecordAdvancedSearchForm"].submit();
}

The filed needs to set itself to ="ADVANCEDSEARCH" which it does , I check it with alert statment ,
but in the action class when i try to read the parameter

actionRequired = request.getParameter("actionRequired");
is get a empty string .
Why would something like this happen , where could i be lossing the data for the hidden field .

plz advice

would you mind posting your complete form ?

Hi
Yes, post your complete form.

1. May be you have not put your "hidden field" in your "form".
2. Try using hidden text box
<input type="text" name="actionRequired" style="visibility:hidden"/>

I think it may help.

it's the fact that your javascript code is wrong that's giving you the problems I feel...

Just to debug:
Try to make hidden field as text field:

<input type="text" name="actionRequired"/>

then when you submit see what value you are getting in there.

If it is holding the value then your form class, or action class is malfunctioning.
