Description Ulrich Hobelmann 2017-02-02 03:04:06 EST

What steps will reproduce the problem?
1. The project is an imported Maven/Java project.
2. Convert to facetted project.
3. Enable JS for the project, so e.g. JS save actions will work.
4.  One affected file looked like this (using JIRA's AUI / AJS library).

AJS.toInit(function() {
    AJS.$("#filters").auiSelect2();
    AJS.$("#dashboards").auiSelect2();
});
