@bigopon - I see that you are a contributor on the aurelia-ui-framework, do you have any idea why I would be receiving the error:
Possible Unhandled Promise Rejection: TypeError: Cannot read property 'attrToRemove' of undefined
when adding the plugin into main.ts? I have tried using useResource and am able to add UIResources.Buttons and UIResources.Menus ok, but the error happens when adding UIResources.DataPanel. I am trying to use the grid and it is part of the DataPanel.
