The links that actually cause this have been commented out as part of https://sakaiproject.atlassian.net/browse/SAK-5774#icft=SAK-5774

This link has been removed from the info page in resources. So it shouldn't occur in 2.3.

That being said, it's possible to create an url:

https://server/portal/tool/resource-tool-guid/?collectionId=valid-collection&sakai_action=doNavigate

which will cause a similar exception, either on the current page or the next page that the user navigates to.

(This is simply a warning about there being other possible places that similar exceptions could cause.)

Steps to reproduce:

Maintain user creates a folder, adds a file to that folder.

Access user then clicks into that folder and then clicks on info.

Access user then clicks on the "breadcrumbs" at the top.

The killer line is:

9602: canDelete = contentService.allowRemoveCollection(collectionId);

(Current trunk: 10284)

thus implying that:

9559: org.sakaiproject.content.api.ContentHostingService contentService = (org.sakaiproject.content.api.ContentHostingService) state.getAttribute (STATE_CONTENT_SERVICE);
(Current trunk: 10242)

is incorrect somehow.
