Hello,
In XML a •boolean• can have the following legal
literals {true, false, 1, 0}. However, when mapping 1
to a Boolean (the object), I expect the value to be
true, but the value is actually set to false. After
debugging through the method calls, it appears that
when using a Boolean, the Boolean constructor is
called [public Boolean(String s)] and that only
compares for the strings true/false not 0 and 1.
We can write a custom marshaller to handle the Boolean
case, but it is a sneaky problem. If we change a
variable from boolean to Boolean, the mappings will
appear to work until we realize the values are off and
remember to change the mapping to use the custom
marshaller. Any tips on a better way to handle this?
Thanks,
-Jennifer
----------- Code Samples -----------
/** Sample Class, the comment denotes the value of the
variable after unmarshalling */
public class TestClass {
private boolean b1; //value is set to true
private boolean b2; //value is set to false
private boolean b3; //value is set to false
private boolean b4; //value is set to true
private Boolean b5; //value is set to true
private Boolean b6; //value is set to false
private Boolean b7; //value is set to false
private Boolean b8; //value is set to false !! This
is not expected. It should be true
}
