How to change the address where Guvnor and Designer are running ?

Issue

• If JBoss is bound to an IP address different than localhost (using the -b parameter), the business process designer doesn't work. It's impossible to load or save diagrams.
• Having configured JBoss Enterprise BRMS server to run on specific IP address, the BRM (i.e. Guvnor) throws the following exception while saving a process definition from Designer. Any idea how to fix this issue or are there any configuration changes which needs to accompany with respect to this IP address change?
