Subject HttpServletRequest getParameter function returning null
Date Sat, 02 Feb 2019 10:23:58 GMT
So I came across two issues once I updated the version of guacamole to 1.0.0

1) HttpServletRequest doesn't hold any of my parameters anymore
2) Can't connect to clients anymore due to *java.lang.NullPointerException


Looks like the guacamole tunnel is receiving the request fine, here are the

Checking through the network tab of the inspect element tool, I can verify
that form data is being populated when sending request to the tunnel...

Now when I take off any *getParameter* and just hardcode the parameters, I
get this error back when making a request to the tunnel:
