How can I circumvent NullPointerException in data bindings?

Question

I try to select an entry in a combo depending on a value in a record set like that:

panel.comboCountry.selectedIndex 
    <- Integer.parseInt(in.EmployeeList.getField(in.RowId,"country").toString())-1

This works properly, but if NULL is stored in the recordset, then Ivy throws a NullPointerException.

How can I circumvent this?

Accepted Answer

0	Use the unary ? : operator on the right side of the data binding: `in.EmployeeList.getField(in.RowId,"country") is initialized ? Integer.parseInt(in.EmployeeList.getField(in.RowId,"country").toString())-1 : null` link answered 18.01.2012 at 10:06 Martin Steiger (suspended) accept rate: 50%
