JComboBox AddItem

[ideru]

@Norm, the combobox object was created during the initialization and is used during insertion of items to it.


Right , Ive noticed that the behavior of addItems is inconsistent.

this is how the original code looks like

 
	ArrayList<ParameterBean> beanList= new ArrayList<ParamaterBean>();
	beanList= getListNames();  //  this will return all names retrieve from the DB
 
   if( beanList.size() > 0 )
   {
		   //get each item from the list and insert to the comboBox using addItems
	}
   else
   {
	   // set a temporary value to combobox
	  String strTemp = new String("DB Is Empty " );
	  this.comboDataList.addItem(strTemp)
 
   }

the else part will cause an exception. In "ParameterBean" , I have a getName() function that returns a String. So for each Parameter, I insert the String value using addItem to the ComboBox and no Problems. But I explicitly insert a String like the one in ELSE part, it will cause and exception.
