[Dspace-general] "Take Task" button does not work

Wed May 20 04:50:20 EDT 2009

Dear All,

We are currently running Dspace 1.4 and for one collection we have configured
some submitters and one "Approve/Reject" person, so that she will be able to
check the inserted metadata of the items before accepting it for publication.

However, we are facing the following problem. The submitter user is able to go through all
the steps when submiting his essay/item and gets the e-mail notification about the fact
that the essay is "in-queue" waiting to be confirmed. Then the "Approve/Reject/Administrator"
of the collection logs in and sees in her "My DSpace" the task waiting to be approved with all
the related buttons, among which is also the "Take Task" button. 

The problem is that when she clicks on the "Take Task" button, it displays a blank page at the center, while all the other elements
of the page (navigation bar at the left, logo at the top, information bar at the bottom, etc) are displayed
the item per se, or any other information that should have been displayed at the center of the screen are
not. It is just a blank page.

I have checked the log myself (dspace.log) and I quote the final lines of the log that I have come
across with bold the last two reporting the exact error.
