I was using RAP 1.5.2 for a while, and switched my target to RAP 2.1. Because I have a problem in RAP 2.1 that I have no solution for, I want to go back to 1.5, so I can continue working on my project while hoping a solution for 2.1 is found some day.
But now when I launch the same app I that launched just two days ago in RAP 1.5, I get
!ENTRY org.eclipse.rap.ui.workbench 4 0 2013-08-14 16:49:24.510
!MESSAGE FrameworkEvent ERROR

I think this is because I still have RAP 2.1 tooling, and there seems to be no way to remove it without gutting my IDE. The feature that provides it is named "Eclipse for RCP and RAP developers" and it contains the eclipse platform, the p2 bundles, and the RCP/RAP feature--the latter which contains a plugin that upgraded my rap tooling from 1.5 to 2.1.
If there's a way to fix the problem I'm having while still using RAP 2.1 tooling, that's fine. But I assume that's not recommended since I'm developing for a RAP 1.5 target.
So is there a way to downgrade RAP tooling, or do I have to start with a new IDE?
