I uninstalled SA and removed all the files from its directory and users AppData on Win7 then I reinstalled it again an have now the same issue. I'm not able to use the userAlias and userClassName of GridPanel in Config.
I'll send you the project archive too.
First I would like to thank you for your time and knowledge
With the above example, MyChart is the userClassName and mychartalias is the userAlias.
Why are you trying to set these configurations? If its so you get a more meaningful name in the inspector, you should use the displayName config. This allows you to name the particular component you're working with, without affecting the code gen at all.
If you truly need a full subclass, you can right click on an individual node and click "Promote to Class". Once it has become a full subclass it will then have userClassName and userAlias.
