the code is
 var token = '';
 for(i = 0; i < count; i++)
token += source.item(i).value + '|' + source.item(i).text;

it's work fine when count < 300, but count > 300 fails

Hi,

I've not checked you are passing the value as query string. Check this knowledge base. The maximum length of query string is 2048.
