Method Detail

postChanges

public void postChanges(oracle.jbo.server.TransactionEvent te)

Description copied from class: JhsDBTransactionImpl

Throw JboException that wraps all messages on stack. If no messages available, call super.postChanges

Overrides:

postChanges in class JhsDBTransactionImpl

doCommit

public void doCommit()

Description copied from class: JhsDBTransactionImpl

Checks whether there are messages on the stack, and throws exception if this is the case, otherwise call super.doCommit postChanges checks as well for messages on the stack. That's because we want to show the errors before posting the changes to the database because we could get unhandled database errors when we try to set a required column to Null. Now, if postChanges already checks the message stack, why do we have to do it here again? That's because there are situations where postChanges is not called but doCommit is. This happens when BC4J thinks there are no changes to post. This happens when a setAttribute method fails in the update method. We trap this failure, and add a message to the stack. However, if this was the only attribute that was updated by the user, bc4j sees no changes and does not call postChanges.

Overrides:

doCommit in class JhsDBTransactionImpl
