#ASSERT: You are connected to OpenShift (you have working connection in the OpenShift view) #ASSERT: You have created app with some cartridge (Mysql, etc.) #EXEC: remove cartridge via Context Menu - Edit Embeddable Cartridges #RESULT: The cartridge remains in the OpenShift view, needs to restart IDE / Click on 'Collapse All' button in the view. The same when removing application (still remains in view). I suggest refressing the OpenShift view after all actions like removing,changing, etc...
