disabling checkbox for 30 seconds

[naresht reddyt]

<tr:table summary="Periodic table"

rowSelection="multiple"
:
:
:
</tr:table>

I am getting the fields populated from database after selecting a checkbox and the user is also able to select another checkbox before the first checkbox request is completed. In this scenario the error reported will manifest.
Here i need to disable the remaining checkboxes for 30seconds.
Can someone please help me how i can acheive this.

YOu can use a bit of javascript

    
function onClickEvent(thisObj, thisEvent) {
 document.body.style.cursor = "wait";
 document.getElementById("yourFormName:yourCheckboxId").disabled="true";
}

When the server is done it should resend the components and the disabled attributes will be reset. Forget about using an arbitrary 30 seconds.
