Java EE (Java Enterprise Edition) General Discussion

Hi all,

I am struck up with this problem for more than five hours and i could not go ahead with my coding. Can any one of you look into and could give an suggestion it could be a great help to me.

I am using Html:Multibox and i use this inside the nested iterate tag to dynamically generate the check box.
<nested:iterate property="alRLDoc">
<html:multibox property="arrSelectedId">
<nested:write property="seq_Id" />
</html:multibox>
<!-- display some data -->
</nested:iterate>

The user can check single or more than one check box and click on save button. On click of the save button i want to check if he has selected a value else throw an alert message.
I wrote a js like this but it doesnt work.
if(document.ReportForm.arrSelectedId != null){
document.ReportForm.strTabInd.value = 'N';
document.ReportForm.submit();
}else{
alert("Please Select an Document");
}
And in some scenarios i need to check how many values are selected. If its more than one i need to throw an alert. I am also not able to do this because if its a single java script does not consider it as a string array.
Please help in solving this problem.

Regards,
Arul.
