Losing connection data and all subscriptions when closing the window. #84

Open HamzaHajeir opened 4 years ago

HamzaHajeir commented 4 years ago

Hi

Mqtt-Spy works well and it solved me a good problem of logging, Anyway if for some case the program closes : all connection configs is lost, all log data is lost, And I need to reconfigure them.

Note : When I open connection it gives me this message : (I added all required configs). image

What could be the solution for this issue ? Thanks

I have the same issue. Configuration file in ~/mqtt-spy/mqtt-spy-configuration.xml is never created.

Version 1.0.1 beta (build 18)

Java 1.8.0_265 Oracle

Os: Linux 4.19.77 amd64

This happens when doing: Connections -> Manage connections -> Write "test": on client id and 127.0.0.1 on "Server URI" -> Click "Apply" button

strace log:
