@teleivo when platform 2.0 is finally out, we shall release version 1.0 of the legacyui module to work along with it. Currently we are in the 0.x series because a number of changes are going on making it unstable. For now, if you can compile the snapshot version of the module, it should work with the 2.x snapshot version of the platform.
I understand that its unstable, but I assumed that one of the 0.x releases would be deployable in 2.0.alpha or beta. And I did compile the latest snapshot version of core and module but I get above error.
@teleivo what error do you get when you run 2.0.beta with version 0.2.1 of the module?
