Re: [dev] OTRS Ajax/JSON Issues
Please note that this Ajax communication error only crops up when selecting an entry in either a drop down list or a multiselect box. Apparently there is some interaction with Ajax and JSON behind the scenes. *From:* Dan Stover [mailto:dsto...@emacinc.com] *Sent:* Monday, January 06, 2014 6:51 AM *To:* Development community of OTRS *Subject:* Re: [dev] OTRS Ajax/JSON Issues Thanks, Martin, for your response.

Re: [dev] OTRS Ajax/JSON Issues
I was able to get my Ajax communication error message to go away, at least for now. I installed the apache2-mpm-worker module on Apache (description Multi-Processing Module implementing a hybrid multi-threaded multi-process web server). I used the following on Ubuntu 12.04: apt-get update apt-get install apache2-mpm-worker I am really not sure why that worked. Maybe because the JSON object is so large that it needs more threads(?). But so far the error message is gone. Thanks to all who sent me helpful information…Dan. *From:* Dan Stover [mailto:dsto...@emacinc.com] *Sent:* Monday, January 06, 2014 9:37 AM *To:* 'Development community of OTRS' *Subject:* RE: [dev] OTRS Ajax/JSON Issues Please note that this Ajax communication error only crops up when selecting an entry in either a drop down list or a multiselect box.

Sorry for the delayed response on my part. More information: This problem cropped up (perhaps coincidentally) when I was trying to move a work flow process from beta to live. Some of this had to be manual and some export/import. There was also some customized code that is used in certain situations. When this problem occurred, I tried to solve it and was unsuccessful. I then went back to a previous backup of OTRS and the problem was still there. I then restored from a week before I did anything (when it was working fine) and the problem was still there. Did you delete all caches during the restore? OTRS is very eager to use the caches for performance reasons, and invalidates the caches whenever you change anything in the database through the OTRS code. When you change the database directly, you have to also invalidate the caches yourself. Also as Renee said, please look into your web server's error log (plus into the OTRS logs, if it logs into another location.

Hi Dan,
On 12/28/2013 04:44 PM, Dan Stover wrote:
I am running OTRS 3.2.7 and have a beta system running at the same time.
A while back, I ran into an issue on the live system where, when a user
selects an item from a dynamic field drop down list, an Ajax
communications error is generated. This does not happen on the beta
system on the same virtual machine.
Could you please be more specific? What's that error message? If you do
it in firefox with firebug enabled, what does the Net tab show? Are
there any error messages in the log?
FWIW I could imagine that an incomplete user record in the database
causes server-side errors, and that would explain why you don't see the
same error in beta (which hopefully uses a different database).
It appears to be related to the following call in AgentTicketProcess.pm
but is endemic through the entire live system (only with drop down lists
and multiselect boxes);
my $JSON = $Self-{LayoutObject}-BuildSelectionJSON( [@JSONCollector] );
Any advice would be appreciated. Thanks…Dan.
Cheers,
Moritz
