Reg Sublist column setUrl

Hi all,

I  need a favor , when i am creating the sublist i need to add the link on the number column field . This is the code


var columnLink=JVList.addField('tranid','text', 'Number');
columnLink.setURL(nlapiResolveURL('RECORD','journalentry'));
columnLink.addParamToURL('id','id', true);

This is the Journal Entry record and when i add this to code .and open the suitelet window and seems blank.

and if i remove this setUrl code then code run properly.

So can plz tell me why this is happened ?
or tell me the appropriate solutions to add the link into the sublist column field.
