Hi all,


We have run into the following behaviour.

We sent a presentation with an invalid url to the DMP and ever since we werent able to control it through DMM.

The dmp was not responding to any command sent through DMM (presentations/system tasks)

The only option to bring it back is to restart it through it's web gui.

Is this a known bug?

This is a known issue.



Check out:
---------- 
CSCte67952 - DMD:  RSS will not work after upgrade to 5.2

 
Symptom:
--------
The RSS ticker is not showing some content after upgrading to 5.2.
 
This is because DMD in version 5.2 uses Flash to display the RSS ticker.  
And the Flash 9 and 10 player has built in security to not allow content 
from another domain.
 
This security feature is blocking the content.
 
 
Workaround:
----------- 
There are several options available:
 
1: Only use RSS feeds from sites that allow cross site scripting.
 
2: Use a service line "Yahoo Pipes" service that acts as a proxy. This 
   will result in a a new URL that can be used in the DMD, bypassing 
   any cross-site scripting.
  


Additional Note:
----------------
If you use the standard RSS feed in the Signage Design tool, it will work 
with any RSS feed you have and you don't need a crossdomain policy file.

Cross Domain refers only to Adobe Flash Player and the ability to read content 
from other domains. Its a security issue

As an example:
If your SWF file is hosted on www.cisco.com/flash/myflash.swf
And that SWF want to read any content (xml, rss, etc..) from rss.cisco.com/myrss/xml
That is allowed

If that same SWF file tries to access data on www.google.com/somedata.xml
That would require a crossdomain.xml at cisco.com/crossdomain.xml that lists google.com
This allows the Flash player to access content at google.com

I 'd like to thank you both.

It seems that we need to set up the rss proxy.

By the way, is there any option to set the speed of the RSS ?

Thank you
