SAP Fiori use no buffer

Hi experts,

I have the problem that my Fiori-App buffers the data on start and always use the buffered data, even if I have changed the data in filesystem. So I need to know how I can determine that the data is never taken out of the buffer or not buffered at all.

I am creating and using JSON-Model at Runtime out of a JSON-File and want to show the new data after every change of the data in the file.

Thanks in advance.

Best Regards,

Jay
