How to set UI5 version for standalone apps in Java Portal?

Hello all,

I am struggling with version differences of standalone UI5 apps (UI5 iViews) and Launchpad apps. I have enabled Fiori 2.0 design and activated the 1.52.X sources. In the FLP everything is just fine but standalone apps always run with 1.38.X. Is there any way to get every UI5 app running with the newest available build on the portal?

--> System is NW 7.5 SP11

BR and Thanks,

Tobias
