ERROR: Delivering these changes would introduce gaps in the stream. You are trying to deliver a subset of the outgoing change sets but they need to be delivered together because of dependencies between them

We are using a local repository workspace in which streamA is set as source stream and streamB is set as target stream . We want to deliver the changeset to a component so we are accepting the incoming changes from the source streamA for that particular component. We are using the follwoing code for accepting the incoming changes:

componentsToBeAdded.add(
                 localWorkspaceConnection.componentOpFactory().addComponent(workItemHandler.getComponent(), true));
          localWorkspaceConnection.applyComponentOperations(componentsToBeAdded, null);

           // Extract the changeset history report only from created local
         // workspace
            IChangeHistorySyncReport streamChangeHistorySyncReport = localWorkspaceConnection.compareTo(
                    streamWorkspaceConnection, WorkspaceComparisonFlags.CHANGE_SET_COMPARISON_ONLY,
                 Collections.EMPTY_LIST, null);

          // Only accept the changeset in the component. Baseline history not
         // required
         localWorkspaceConnection.accept(AcceptFlags.DEFAULT, streamWorkspaceConnection,
                 streamChangeHistorySyncReport, Collections.EMPTY_LIST,
                  streamChangeHistorySyncReport.incomingChangeSets(workItemHandler.getComponent()), null);


Where streamworkspaceconnection is the workspace connection created for source streamA. When i checked in the local repository workspace , the incoming changes for that particular component were not accepted and it did not even throw the error .

And while delivering a changeset it throwed the error: .

Do i have to add some extra check before accepting the incoming changes. I looked into various ways of gaps could be handled but did not get the solution. Can you please help.
