Subject Re: Upgrade Tomcat procedure [to avoid latency/UI bug]
Date Thu, 21 May 2015 16:18:20 GMT
Ah, didnt notice workarround was was related to first issue...

As for the first issue, I dont experience it anymore (for whatever reason -
I did no changes really on OS side, expcet upgading ACS from 4.3.0/1 to
4.3.2).
Yes, I was just testing the breadcrumb stuff - and started this thread
because of that - sorry if I was not clear on this...

But this Tomcat version replacement - is also related to the first issue ?


Thanks for taking the time!

Cheers
