I'm writing a unit test for a patch and I'm getting a
NullPointerException in an interesting place.
I have a property defined like this:
@Property
@Persist(org.apache.tapestry5.PersistenceConstants.FLASH)
private static Map<Integer, TestObject> selected;
and in method
public boolean isObjectSelected() {
final TestObject obj = getLoopObject();
// This line causes a nullpointerexception
final boolean notNull = selected != null;
return notNull && selected.containsKey(obj.getId());
}
If I use the default Session persistence then I don't get the null
pointer exception. I'm not having any trouble narrowing it down.
Here's the interesting part of the exception:
Caused by: java.lang.NullPointerException
at
org.apache.tapestry5.integration.app2.pages.TestPageForCheckbox.isObjectSelected(TestPageForCheckbox.java:82)
at $PropertyConduit_129ce4d1f5a.get($PropertyConduit_129ce4d1f5a.java)
at
org.apache.tapestry5.internal.bindings.PropBinding.get(PropBinding.java:59)
Thoughts?
