Hi,

I am having an strange problem with Wonder's clearSnapshotForRelationshipNamed method.

Is this new code, by chance?


(My Wonder version is a few days old)

We have EOs which are related to each other:
RoutingMediaItem   <<--->   RoutingMediaStatus

When I try to get an up-to-date status object and check the results using:

ERXEOControlUtilities .clearSnapshotForRelationshipNamed(routingMediaItem, RoutingMediaItem.TO_ONE_STATUS);

That method is to clear the snapshot for a to-many relationship, not a to-one. For a to-one, just invalidate the object.


I think this is what you want:

routingMediaItem .editingtContext().refreshObject(routingMediaItem.toOneStatus())


Chuck





AELog.dbg("- routingMediaItem.status() class = " + routingMediaItem.status().getClass().getName());
AELog.dbg("- routingMediaItem.status().descr() = " + routingMediaItem.status().descr()); // This is line 100 of RoutingMediaBatch, and descr() is a normal string


The first debug prints what you would expect:
- routingMediaItem.status() class  = RoutingMediaStatus

The second line explodes with:
java.lang.ClassCastException: RoutingMediaStatus

I am a little confused as to what I am doing wrong here (or what I have broken).
I thought it might have been some weird AJAX thing, but I replace the AJAX links with normal ones but the problem persists.


Regards,

Mark
