Hi Nate, Hi Sergio,
en.json file is laoded typically for Date Formatting. In case you have specified the date type for your data binding as specified here :
http://help.sap.com/saphelp_hanaplatform/helpdata/en/91/f2fff06f4d1014b6dd926db0e91070/content.htm , theUI5 framewrok loads this file.
Looking at the trace that you have provided, looks like the call is made after a long dealy from the previous request. Looking at this the issue does not seem to be with the dowload of en_json, but rather what is happening before that. Do you know if there is any processing that is happening on the client side which is blocking the execution? I see that the previous call to en.json is a download of an image, and looks like is initiated by the application and not the framework. Could you verify if there is any processing that is happening on load of this image in the application?
Thanks and Regards
