Refresh of referenced objects titles with custom layout

[Deacon Frost <df...@gmail.com>]

Hi,

first of all thanks for the latest release and also the latest screencasts
-- Apache Isis keeps getting better and better!! :)

I am using the wicket viewer with v 1.12.1. I use a custom
<Object>.layout.xml file copied verbatim from SimpleObject with tabGroups
displaying properties on different tabs. If I create a new object or update
value properties of an existing one, the titles of referenced objects get
reset to "undefined ...". If I just click on the tab-title, the screen gets
updated immediately to the correct values. (The behavior is correct as
expected when I remove the layout.xml-file.) Am I missing something or
might this be a wicket viewer bug?

Also, is there any chance to get the value of the changed object in an
"updating()"-event? or do I have to resort to a custom publishing-module or
hook into jdoPreStore?

Cheers,

Deacon

Hello Dan,

thanks a lot for the quick reply!
I'll try out 1.13.0-SNAPSHOT and see how that goes...

Cheers,

Deacon

Hi Deacon,

Thanks for the thanks!

With respect to that problem, I believe this is ISIS-1396 [1].  Yes, it is
a Wicket viewer bug, which has always been there I think, but only now
showing up with the new layout.xml.  Anyway, it is fixed in
1.13.0-SNAPSHOT; perhaps you could build from source [2] and see if it
addresses the issue.

With respect to your query about updating(), what do you mean exactly by
the "value of the changed object".  I suppose if the object has changed
because of a property edit, then you might mean the old/new values of that
property?  But the object might be changed because of an action invocation,
in which case many of its property values will have changed.

Perhaps what might help is to use
@DomainObject(updatingLifecycleEvent=...).  This is just a lightweight
layer on top of the JDO lifecycle events, but to save you having to dig
down to the JDO PersistenceManager.  Maybe that would do the job for you?

Alternatively, if you do need fine-grained visibility of changes in state,
then there's the AuditingService3 API that you could implement.

HTH
Dan
