New Revision: 1730

Modified:
   trunk/src/jar/resolver-spi/java/org/mulgara/resolver/spi/TuplesContext.java
Log:
Added some error logging to pick up those cases when a Tuples isn't resolving correctly. This will usually only happen when debugging in Eclipse (since Eclipse creates copies of some objects when you look carefully at them instead of reusing them)

Modified: trunk/src/jar/resolver-spi/java/org/mulgara/resolver/spi/TuplesContext.java
