Its working fine.
The issue is when I add more than 15 roles per user, some files (bootstrap.min.css, kie-wb.css, clean.css etc.,) are not loading and hence the hidden images are now loading again by showing error in browser console like "Failed to load resource: the server responded with a status of 400 (Bad Request) BPM/org.kie.workbench.KIEWebapp/gwt/clean/clean.css".
Please share solution if anyone knows.
I tried with jBPM 6.4 release and I cant see any issue.Which jBPM version you are trying with ? Try with latest release.
