Updating Live Data

Having an issue with Live data that I hope more experienced users than I can help with.

 

I am working on a project that displays user names on an hd220 using live text event from an xml file.  This list is fluid (ever changing), depending on updates to it.  issue is that the player is "ghosting" entries as the entries change.

 

I think the easiest way to resolve the issue it to have the system do a refresh or "update live data" command, to flush out the ghosts.

 

My presentation is fairly simple (i've actually had to make it a bit more difficult due to a found RSS bug by BrigthSign)..

 

I am looking for a looping playlist:

1.  HOME.. User names listed on display board

2..RSS feed (ive had to separate the rss feed into individual pages, as if I just put in and expect the rss feed to run, then go back to step #1, it does not, it keeps looping on itself, and does not go back to home).

2.  rss feed index 2, 3, 4, etc..

3.  Back to HOME.. loop again..

 

my issue is that if I have "customer1, customer2, customer3" on my xml file, it displays OK.  If i update my xml file to delete "customer 2" then the file becomes "customer 1, customer 3, NONE".. 

 

The issue is that teh display will show "customer1, customer 3, customer 3" (it is not clearing out "the third index of customer 3 (which now moved into index2 position).

 

If I can execute a "update live text" command BEFORE it displays again, it would clear this issue up immediately.

 

I am also trying to see if I can get the system to update teh read to the xml file to faster than 30 seconds, but Brightsign does not recommend it.. it should never be more than really 10 - 15 names total, so it is not a huge amount of data..

 

any suggestions on how to do this, or will teh "update live text" command do this for me??

 

BA helpdesk just sent me an faq on udp inputs and not much else.

 

Any help is greatly appreciated.

    Try not to delete the second item (that corresponds to customer2) from xml file completely, but leave the description tag empty.

    Thanks for suggestion.. unfortunately, can't do that , as it is an ever-changing list, and I only need to display fields 1-6 (or 1-10 depending on store) so there will always be changes to the files, and the users wil always be changing as well (they will "bump up" as neded.. the verify live data is what I need help with.

    What exactly do you delete in the new version of xml file? Do you delete the description tag in the second item? Please attach two xml files (before and after update) to this post.

    Here are the before and after jpg of wha tis going on..

    system creates my first 4 customers (i named them custome 1, 2, 3, but could be bob, harry, mary)...

    (this is created when I "call" or "page' them (this will display their name on the display board using a live text item..

    When they come up and I seat the, I then press "seat" on my system and it removes them from the xml file (deletes) them.

     

    you then get xml #2

    (for this example, I "seated" cusomter 3, so that is teh customer that is now NOT o the display

     

    what is happening, is that I am getting a "ghost" customer 1 on the display..

    here is xml 2, (hit save comments instead of attaching the #2 files)

     

    Original display showed:

    Customer 4

    Customer 3

    Customer 2

    Customer 1

     

    AFTER I "seated" customer 3 (they are never seated in order)

    display shows:

    Customer 4

    Customer 2

    Customer 1

    Customer 1

     

    (the second Customer 1 on the 4th index location is a "ghost".. it should have dissapeared when it bumped to location 3, but it does not).  If I could figure out how to run the "update live data" command "not just read the data, that would most likely solve my problems...

     

    thanks in advance!

    I saw this problem recently with another customer. I'm trying to track down the cause, but one temporary workaround is always publish the same number of entries. Let's say for example, you're going to display up to 10 customers. Create a list of 10, but leave the description tag blank for the ones that aren't used. So, if you have 5 customers, leave 6 - 10 with title/description tags, but leave the description tag empty.

    Thanks for all the work on this..

    unfortunately, the temporary workaround is not a viable fix at this moment, as this is custom programming I already had done and paid for, plus the file is ever changing.  If it just left the tag empty, I would have a pretty quirky looking wait list.  IE, I woudl have guest 1 , nothing, guest 3, nothing, nothing, guest 6, etc... would not look right.

     is there a way you guys can create a script patch I can attach to the live feed, that every time it updates the data (reads the file) it does a "verify live text data" just as the BA button does and attach that to the system?

    I need a working solution by end of next week, as I am installing on wednesday week after that in one location and this has to work.

    thanks again for all your help.
