I have an app that I just upgraded to 4.2 from 4.1.2. I'm using the sandbox version because we still haven't fully migrated everything to Ext 4 yet.
I managed to create my new theme following the guide from the docs, I split all my scss files to be class oriented like suggested (creating a folder with the app's namespace name). My theme extends the ext-theme-classic-sandbox theme. Changed a few vars in the /var/Component.scss. Moved all my sass for each file matching the classe's name. Compiling works sort of, only issue I had is that I had to import each sass file I added that matched my classes (figured it would pick them up automatically). Everything compiles and I get the expected results.
The real issue im having is that I can't use any mixins. When I do something like this :
I get an error : Undefined mixin 'extjs-panel-ui'. None of the mixins are working. Anyone had a similar issue or has a idea what might be causing this problem?
I know I use to have to include ext4/default/all, which isn't required anymore.. is there an alternative to this or everything gets included from the parent theme?
