Please wait on the browser
Description of problem:
Business Central not properly loading after authenticating. Sometimes it will remain stuck at "Please wait" "Loading application..." Sometimes after a refresh of the browser it will properly load Business Central. Inconsistent behavior.
Version-Release number of selected component (if applicable):
BPM Suite 6.1.0 & 6.1.3
Fairly consistent reproducibility
Steps to Reproduce:
1. Start BPM Suite server
2. Login to business central, http://10.0.0.7:8080/busines-central
4. Stuck at "Please wait" "Loading application..."
Browser remains stuck at "Please wait" "Loading application...".

As a quick test, I tried adding the cache entries referenced in GUVNOR-2280 to my kie-wb.html and I still get the same issue of being stuck on Loading...

I don't seem to see this issue on RHEL 6.5, but I do on RHEL 7.1. Don't know how this is impacting it.
Neither engineering nor QE could reproduce the reported issue. There is a possible workaround for this issue already documented in community. Product documentation is requested in bug 1322327. As there was no code change either, I am closing this.
