Charles Crouch commented on EMBJOPR-44:
---------------------------------------
Fixed in embjopr r61
So this turned out not to be caused by the UNKNOWN availability status, which we handle fine, but rather after the create war request was completed successfully we weren't raising an event to indicate that the underlying resource tree (used by the nav, and the breadcrumbs) needed to be updated.
So instead of adding another place in the view layer to raise an event, I moved all the event raising code into the PluginContainerResourceManager, so now clients don't need to worry about checking the status of the change and raising the event themselves, it should all be done by ResourceManager.
At the same time put in a couple of fixes to improve the support for finding the correct parent node to refresh when a new node has been added.

> Saw this after deploying a new .war file into JBAS4.2.2. Its not reproducible all the time. Steps
> 1) Create a new web app resource by uploading a new .war file
> 2) Get message saying resource has been successfully created
> 3) Browse to the new resource in the list on the main page, note its status is UNKNOWN
> 4) Click on the resource and you are shown a page with the platforms information on, and the exception below is in the logs
> Waiting and trying clicking again doesn't seem to help, but logging out and in again resolves it. The status is shown as available and clicking on the resource name brings up the correct page.
