The Studio IOC mechanism from the Studio core has been removed. Usages of the ComponentContextManager and the ActionScript annotations ProvideToExtChildren and InjectFromExtParent need to be refactored into using ValueExpressions with plain ExtJs component configurations.

ContentAction  doesn't have the config parameter _contentVariableName_ anymore and the content must be configured by the parameter _contentValueExpression._

RichTextAction has a new config parameter _ckEditorValueExpression_ which is mandatory. Instead using the action directly it is recommended to use the components _RichTextMenuCheckItem_ and RichTextMenuItem which have the action's _ckEditorValueExpression_ already configured.
