HiveMind can be too demanding about cross-dependencies within
hivemind.FactoryDefaults
--------------------------------------------------------------------------------------
Key: HIVEMIND-170
URL: http://issues.apache.org/jira/browse/HIVEMIND-170
Project: HiveMind
Type: Bug
Components: framework
Versions: 1.0, 1.1
Environment: HiveMind 1.1
Reporter: Howard M. Lewis Ship
I have the following contributions to hivemind.FactoryDefaults:
<contribution configuration-id="hivemind.FactoryDefaults">
<default symbol="peg.host" value="localhost"/>
<default symbol="peg.port" value="8090"/>
<default symbol="peg.context" value="pe"/>
<default symbol="peg.base-url"
value="http://${peg.host}:${peg.port}/${peg.context}/peg"/>
</contribution>
It seems reasonable to me that I should be able to reference other symbols
defined at the same level, but I get a failure at application startup for my
Tapestry application. In fact, I get an unbelievable torrent of nested
exceptions, none of which point to the above XML.
etRootCause():
