Samet,
The table mendixsystem$version is not accessible through mendix nor is there an Mendix function available in the api of mendix. See:
https://apidocs.mendix.com/4/runtime/classcom11mendix11core11conf11_configuration.html#a6e69476a58953906a3b260ec77737ad6
I have submitted a support request to Mendix.
Kind regards.
See this post. I suggest filling a feature request. The more requests the more it is likely it will be realized.
Regards,
Ronald
Hi Wouter,
You can use the form loader widget to load a form in your theming. So just create a dataview which shows your current version. Maybe you could use some java to retrieve the current revision.
