Corda Bugs - Accounts Keys

This demonstrates a problem of the Accounts SDK and how it handles PublicKeys.

Run ./gradlew test to see the failing test.

The contract tests pass and creating an IOU test passes, however, updating the IOU fails.

com.github.opticyclic.corda.demo.accounts.flows.IOUAccountUpdateFlowTests fails with:

 java.lang.IllegalStateException: Can't find Lender account on this node
    at com.github.opticyclic.corda.demo.accounts.flows.IOUAccountUpdateFlow.call(IOUAccountUpdateFlow.kt:86) ~[main/:?]
    at com.github.opticyclic.corda.demo.accounts.flows.IOUAccountUpdateFlow.call(IOUAccountUpdateFlow.kt:25) ~[main/:?]

This is further confusing because before the test runs it asserts that it can find the Account on the node.

The different between the two account lookups is that before the test it looks up by UUID and during the flow it uses the PublicKey from the state to look up the account.

Fix

In the develop branch you can can see a fix where an extra flow is run at the end of the main flow that synchronises that states and accounts.

This allows the accounts to be subsequently looked up by the PublicKey stored in the state.
