------------------------------------------------------------------
Note to myself:
Looking at the code, if default-cache is not defined as a cache-container attribute, then
(briefly):
- CacheContainerAdd will create an EmbeddedCacheManagerConfigurationService with a
defaultCache value of null
- DefaultEmbeddedCacheManager, which is an AbstractDelegatingCacheManager, will have a
defaultCache value of null
- when we call DefaultEmbeddedCacheManager.getCache(), rather than returning the cache
corresponding to cache name defaultCache, it will return the cache corresponding to cache
name null, which will correspond to the default cache of DefaultCacheManager, which is
__default.
Thus, leaving default-cache undefined may cause no exception to be thrown, but the
application gets the DefaultCacheManager's default cache, which is __default. The
settings for the default cache will have been specified in the <default> section of
the cache manager configuration (as opposed to the <global> section.
So, if the subsystem does not set the default-cache for a cache container, it will get a
default cache none the less - but perhaps not the one desired.

Make default-cache attribute of cache-container not required.

Key: AS7-3488
URL: https://issues.jboss.org/browse/AS7-3488
Project: Application Server 7
Issue Type: Feature Request
Components: Domain Management
Affects Versions: 7.1.0.CR1b
Reporter: Richard Achmatowicz
Assignee: Richard Achmatowicz
Fix For: 7.1.2.Final
Can we remove the restriction that default-cache must be set when you create the
cache-container? That way, I can just make it so the UI
forces them to set that value before calling the start operation. So under that covers,
the console does this:
{noformat}
<!-- user creates a new cache container without specifying default-cache. -->
/subsystem=infinispan/cache-container=X:add
<!-- for top-level cache container attributes, user sets them via write-attribute
-->
/subsystem=infinispan/cache-container=X:write-attribute(name=jndi-name,value=W)
<!-- for nested nested cache-container attributes, user access them as an addressable
resource and sets them via write-attribute -->
/subsystem=infinispan/cache-container=X/transport=TRANSPORT:write-attribute(name=stack,
value=udp)
/subsystem=infinispan/cache-container=X/transport=TRANSPORT:write-attribute(name=lock-timeout,
value=100)
<!-- When user is ready to start the cache-container, prompt for default-cache if not
set. -->
<!-- Then do these two as a batch -->
/subsystem=infinispan/cache-container=X:write-attribute(name=default-cache, value=Y)
/subsystem=infinispan/cache-container=X:start(mode=on-demand)
{noformat}
Any thoughts on this? The answer has great implications on the UI design.
