Re: Wierd ClassCastException on WebAPI calls

  Thread Previous • Date Previous • • Thread Next 


yea, its just /api/resources
If you have access to one of the uio desktops and try the IE8 in that, you can replicate it as well

That looks really strange. What is the request you are doing? is it just /api? Resources are definitely not a idObject--

      Hi Sap,
        

        
        Do you have a stacktrace or something we can use as a
          starting point?

                On certain browsers and client's I've
                  seen a wierd ClassCastException thrown from the
                  server.

                  The status returned is 500.

                  But this happens only on certain clients in IE8 and
                  Android ICS.

                  It works fine with Chrome, Firefox etc.

                  

                  May be its related to accept header and the mimeType
                  its sending for text/html. But this is only a wild
                  guess.

                  Will be good to fix before the 2.13 release.
