[jira] Created: (TAPESTRY-218) Persistent properties cant be set to null
Persistent properties cant be set to null
------------------------------------------
Key: TAPESTRY-218
URL: http://issues.apache.org/jira/browse/TAPESTRY-218
Project: Tapestry
Type: Bug
Components: Framework
Versions: 3.0
Environment: IBM WebSphere 4
Reporter: Michael Frericks
situation:
If you set a persistent property to null, this finally invokes
SessionPageRecorder#recordChange
...
_session.setAttribute(attributeKey, newValue);
...
where newValue is null.
The ServletAPI 2.2 says:
newValue - the object to be bound; cannot be null
So we tested and saw that the IBM WebSphere 4 really did not
accept the null value and the propety was not changed.
That is ugly.
solution:
Change
SessionPageRecorder#recordChange
...
_session.setAttribute(attributeKey, newValue);
...
to
if(newValue != null)
{
_session.setAttribute(attributeKey, newValue);
}
else
{
_session.removeAttribute(attributeKey);
}
