Jqgrid muti select does not work

Hi all I am using this tutorial http://ift.tt/1CyNjOg I installed the project by using the code svn location said in the above code. I ran the server glassfish on netbeans i can see page comesup, but the multiselect does not work, >> button to next page does not seem works, it does not load result exactly. what could be the issue? All i want to implement multiselect checkbox ike this example. http://ift.tt/1sJoijf I am using struts2, jquery, jqgrid. i need to show the data from arraylist/java. and also add check boxes per row dynmically. but when i select check box and move to next page or prev page, the checkbox state should be checked or unchecked it has to be some how cached., it is one way. i do NOT need to persist checkbox value from database (indeed there is no functionality), all i need is user's checkbox selection status retain selected records while doing pagination. please suggest me the ways TIA
