Description

The resource http://next.dev.curriki.org/xwiki/bin/view/Coll_singhparamjit90/MandBudhiPunjabi

delivers with an error while it delivers fine on current...

It seems to be a NullPointerException in the CurrikiSpaceManager.

The console shows an error in the curriki-space-manager when calculating the parents.

Though I haven't been able to tell for sure, this NPE seems due to a velocity variable that is not properly defined (about the space of a resource). It is likely, thus, to be fixed by the macro-param-by-ref issue.

This is happening several others.

Right now on current, I tried transferring the history-of-pizza (to my desktop) and it stopped showing the issue.
Also, the other URL
http://current.dev.curriki.org/xwiki/bin/view/Coll_singhparamjit90/MandBudhiPunjabi
works flawlessly.
I note that in none of these cases is there a parent (I also checked on prod). So it was the collection parent display into the breadcrumbs.

I'm starting to detect the reason for this issue: the resources that appear candidates as parent are protected resources thus are not displayed.

http://current.dev.curriki.org/xwiki/bin/view/Coll_Nobiah/THEHISTORYOFPIZZA can be viewed worry-free as administrator.
But not as normal user (same error).

When you view as admin you see that the parents are the collection 3s and Language Arts Reviewed Resources. The latter is restricted (and requires me to login).

The null-check just committed should fix it.
But maybe we're underperforming.

This seems a likely cause. The question is, why does this error not occur in the current released version? We need to narrow this down further and identify what changed.

Joshua,

I won't find out "what was changed that broke it" if I cannot differentiate the collection 3s and the root collection which, apparently should not be displayed.

Fixed for all.
Now also checking for authorization before adding a parent.
Apparently that was not made.

The problem with the fix is now I cannot see the collection especially on the left TOC. So now, even as an Admin, I cannot tell that there is more to the collection.

Works fine on Production.

Todd,
I think your difference was an editorial one. Janet probably added it to a collection later.
At least on prod, with the new code, it shows with Janet's collection.
