chk ur code

I think the problem is that you have removed the elements from the node and again trying to access the same node

This Is the code of delete function.

//@@begin onActionDelete_Entry(ServerEvent)
    	int Count=wdContext.nodePerson().size();
    	int LeadSelcection=wdContext.nodePerson().getLeadSelection();
    	for(int i=0;i<Count;i++)
    	{
    		if( (i==LeadSelcection) || wdContext.nodePerson().isMultiSelected(i))
    		{
    			wdContext.nodePerson().removeElement(wdContext.nodePerson().getElementAt(i));
    		}//if
    	}//for
    //@@end

Loop backwards (n-1, ..., 0) to keep indices stable when removing an element from the node.
