DEPRECATED: mendix.lang.nullExec (version 1.2.0 in Mendix 7)

[axelbrink]

Version 1.2.0 in Mendix 7.23.8 yields client errors that fill the server log:

DEPRECATED: mendix.lang.nullExec. Use plain javascript if instead -- will be removed in version: 9.0

Could you fix the deprecation issue in Mendix 7?

There is a newer version available (1.4.0), but that doesn't work, in Mendix 7.23.8:

mx.parser.atAttribute is not a function TypeError: mx.parser.atAttribute is not a function

Maybe fixed in 1.2.1 or 1.3.0? Not available in the App Store.
