BeanWrapperImpl: wrong null treatment in array properties [SPR-1823] #6517
Description
Fabio Grassi opened SPR-1823 and commented
Assignig a null value to an array property results in an array with a single null element. I think this is a regression, but was not able to determine exactly. Here is a test case:
public class ArrayBug {
public static void main(String[] args) {
BeanWrapper bw = new BeanWrapperImpl(BeanWithArrayProperty.class);
MutablePropertyValues pvs = new MutablePropertyValues();
pvs.addPropertyValue("elements", null);
bw.setPropertyValues(pvs);
BeanWithArrayProperty bwap = (BeanWithArrayProperty) bw.getWrappedInstance();
Assert.isNull(bwap.getElements());
}
public static class BeanWithArrayProperty {
private Integer[] elements;
public Integer[] getElements() {
return elements;
}
public void setElements(Integer[] elements) {
this.elements = elements;
}
}
}
Thanks in advance, Fabio.
