Subject [jira] Closed: (GERONIMO-4907) GBeanInstance to Ignore Missing Setters
Date Thu, 29 Oct 2009 21:25:59 GMT


David Jencks closed GERONIMO-4907.

    Resolution: Won't Fix
      Assignee: David Jencks

I don't think we should fix this.  I think it's better to know when we are trying to set a
non-settable property and fix it, otherwise we may think info is getting into the gbeans when
it is not.
Possibly the error message could be improvied, its something like

Missing accessor for property: x of class y

> I submitted a patch which fixes the problem by removing the attributes which don't have
> After reading the OpenEJB source I noticed an XBean feature which would be a more correct
fix for the problem.
> Instead of removing the attributes which won't have setters in the class being instantiated
as a GBean, configure the ObjectRecipe to rather ignore those properties which don't have
setters. This has 2 benefits
> 1) Those properties can still be included for "read" access
> 2) If such a property exists for any other GBean, or is added in the future, this will
help that those don't possibly create fatal bugs - which the JettyConnector bug almost was
(you couldn't edit a connector - ever).
> This is achieved by adding the following line after the ObjectRecipe was created:
> objectRecipe.allow(Option.IGNORE_MISSING_PROPERTIES);
> This permissions merely removes the property from the list of properties to "create the
object with", if the accessor wasn't found. 
> Since those properties are still available, they can be accessed by the GBean API, and
thus it doesn't become a requirement to have setter accessors for all persistent properties.
