Subject [jira] Commented: (TAPESTRY-1991) It should be easy to initialize an ASO to null
Date Thu, 03 Jan 2008 20:18:34 GMT

    [ https://issues.apache.org/jira/browse/TAPESTRY-1991?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12555666#action_12555666

Howard M. Lewis Ship commented on TAPESTRY-1991:
------------------------------------------------

If you want to avoid creating it, you can use the exists flag.  For example:

@ApplicationState
private MyState _myState;

private boolean _myStateExists;

public MyState getState()
{
  return _myStateExists ? _myState : null;
}

Thus, you can easily avoid creating the MyState ASO.

> By default an ASO is never null. It's automatically created using the ASO class default
constructor.
> It's many times needed to have the null value in an ASO, for example if i want to keep
the logged in user in an ASO.
> Right now we can do this by contributing a new ApplicationStateCreator to the ApplicationStateManager
but it seems to me that should be as easy as providing a parameter to the @ApplicationState
indicating that you don't want it to be automatically initialized.
