FlexViewer 2.5 MapManager Error 400

[ZdeněkJankovský]

Hi,

we are using custom dynamic site with embedded Flex Viewer 2.5 and ArcGIS Server 10.0 (latest SP).
In some cases our user get strange Error message during loading the the map composition.

Mostly it works without problem, but sometimes users get this error message. I tried with fiddler under the web browser and it doesn't get any request to the server. So it seems that the problem is in the application.

Does anybody encourage the same? What could it bee if the URL is the same and sometimes work and sometimes not?

the proxy URL is in this format:
http://alias.webservername.cz/webserverdirectory/Services/AGSproxy.ashx

the service is in the format:
http://alias.webservername.cz/ArcGIS/rest/services/directory/name_name_name_2013/MapServer

Thank you for any suggestion,

Zdenek J.

Hi!

I have the same problem with flexviewer 3.1
Sometimes I've got the error :

La couche Scan 25 n�??a pas été chargée*: Code d�??erreur : 400

Informations sur l�??erreur : Unable to complete operation.

Détails de l�??erreur : Service 'r_scan25' of type 'MapServer' does not exist or is inaccessible.

Sometimes a simple "F5" and clear cache of the navigator is enough to load the application with no error, sometimes I refresh the services in ArcGisManager.

But this solution is not very proper ! 😕

Have you find another solution ?

Hi,

we are not able to get rid of it completely, but we reduce it mostly.
We set impersonate on the server: similar to http://support.esri.com/en/knowledgebase/techarticles/detail/32620

It helped a lot but not completely.

Any other suggestion can help,

Thank You,
