Why GameObject.activeSelf on a ViewElement not apply properly

Mind that ViewSystem control ViewElement's lifecycle. You should avoid manipulating GameObject.activeSelf in OnBeforeShow(), since ViewElement is not ready yet and GameObject.activeSelf of the ViewElement may be overridden.

This is usually caused by entering Play Mode while editing the View System Editor. Simply delete it.

My ViewSystem Visual Editor show nothing after update ViewSystem version

If you are using ViewSystem versions earlier than 1.0.43 and want to migrate to a later version, you will need to perform a save data migration. Simply click Normalized in tool bar. ViewSystem will detect if old version save data exist, then automatically convert data into new version(every page store separately).
