[jira] Commented: (TUSCANY-1859) Exception when using wires to wire
Components
[ https://issues.apache.org/jira/browse/TUSCANY-1859?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12536159 ]
Mark Combellack commented on TUSCANY-1859:
------------------------------------------
This problem is caused by the references not being built correctly for the wires. It is an assembly time problem caused by CompositeWireBuilderImpl creating the references before the wires.
The original code is:
// Connect component references to their targets
connectComponentReferences(composite, components, componentServices, componentReferences);
// Connect component references as described in wires
connectWires(composite, componentServices, componentReferences);
The fix is to swap the order of the above method calls and connect the wires before connecting the references. The fixed code is:
// Connect component references as described in wires
connectWires(composite, componentServices, componentReferences);
// Connect component references to their targets
connectComponentReferences(composite, components, componentServices, componentReferences);
I've attached WireFix.patch that does the above fix.

> The SCA specification allows components to be connected together using a wire in the .composite file (Assembly specification section 1.6.4 lines 1576 to 1848)
> If I use <wire> in the .composite file, I get the following exception at runtime:
