Re: Unknown argument: -superDevMode

Here are the arguments from Run Congiurations:

-superDevMode -remoteUI "${gwt_remote_ui_server_port}:${unique_id}" -startupUrl ChordEarTrainer.html -logLevel INFO -codeServerPort 9997 -port 8888 -war C:\Users\James-PC\workspace\FINALWORKINGSPACE1\ChordEarTrainer\war com.sinewavemultimedia.chordeartrainer.ChordEarTrainer

 I tried removing -superDevMode but then it defaulted to the very old way using the GWT Dev Plugin which current browsers do no use.

I recently tried to downgrade my app from 2.7 to 2.6. I am now getting the following error in the console and am not sure what to do. What I did was extract GWT source folder to C drive added the sdk via project setting/GWT. I did have an error with the servelt.jar. so I deleted it and used the option from right click to synchornize sdk or something like that.
