Bug 800611

Description of problem:

Use of the horizontal ellispis character in html to shorten long values breaks the render of some widgets in Cumin in the Messaging tabs.

Specifically, the fmt_shorten() routine is being used in several places in the messaging tabs to deal with long values.  One of these places is in the render of the form for an "Add binding" task.  If a queue is selected that has a name longer than 40 characters, the shortening code will insert the horizontal ellipsis and break the xml parsing in the browser.

This likely occurs other places, too (search for fmt_shorten).

Version-Release number of selected component (if applicable):


How reproducible:

100%

Steps to Reproduce:
1.  Set up a Cumin instance with Messaging enabled (modify the peronsa: and datas: values in cumin.conf for Messaging.  This is the default in current releases.

2.  Go to the Messsaging->Queues tab and select a queue with a name longer than 40 characters.  Since the machine name is part of the queue name, you can make one exist by creating a really long host name and running the broker from that host.

3.  From the queue drilldown page, click the "Add binding" task
  
Actual results:

Queue names longer than 40 characters will cause an xml parse error.  Queue names shorter than 40 characters will not.

Expected results:

Queue name length should not cause an error.

Additional info:

Here the output of the parse error from an "Add binding" task on a queue.  The name of the machine has been changed for pasting in the BZ, but the length is the same.  Notice the use of #8230 in the last line of the URL.
