[jira] Commented: (TUSCANY-1260) NPE when component reference has
target composite with custom implementation
[ https://issues.apache.org/jira/browse/TUSCANY-1260?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12494795 ]
Ignacio Silva-Lepe commented on TUSCANY-1260:
---------------------------------------------
Notice that the line "<<< getInterfaceContract, interfaceContract [null] ", which prints the return value of DefaultCompositeActivator.getInterfaceContract seems to say that the reference's contract has not been determined. Could this be because the code to match the Java interface, that the reference expects, to the WSDL interface defined by the target component, does not work any more?
I am trying to figure out where this code is, but on the off chance that anyone can tell whether or not this may be the actual problem, I bring it up.
