When installing optimus with the less compiler provider, a new section Dynamic Stylesheets would be added in the Settings section of umbraco, where you can add less files.

Issue 1 (solved)

To add a less file, I had to manually create a folder called css in the umbraco project's root directory. After, I would be able to create a new less file by clicking Dynamic Stylesheets > Create. This seems to be a bug

Issue 2 (unresolved)

However, when I want to open the newly created less file later by clicking on it on the tree, nothing would happen. :(

I openend a console to see if there is an error, and it turns out there is:

Error evaluating js callback from legacy tree node: ReferenceError: openDyanmicCSSFileEditor is not defined

How can I fix this?

My setup

I'm using

• visual studio 2015
• umbraco 7.4.3 and 7.5 (both have the same symptoms)
