Replace component using client Operations

Hi,
I'm looking for how to replace a component (in order to re-align it with a baseline) through plain api (RTC 3.0.1).

I've tryed different replace methods of IWorkspaceUpdateOperation:

IWorkspaceUpdateOperation wsUpdateOp = IOperationFactory.instance.getWorkspaceUpdateOperation(WorkspaceUpdateDilemmaHandler.getDefault());

wsUpdateOp.replace(workspaceConnection, baselineConnection);

wsUpdateOp.run(null);

For this first method (which has a wrong javadoc, as it says there is a third parameter: component) I use this scenario: one repository workspace with one component flowing with a stream with the same component. At start time the repository workspace and stream are equals (based on the same baseline). I get an old baseline through BaselineSearchCriteria (setting name and component) and then I run the replace.

Second scenario: two repository workspace, one based on a baseline and the other based on a previous one.

IWorkspaceUpdateOperation wsUpdateOp = IOperationFactory.instance.getWorkspaceUpdateOperation(WorkspaceUpdateDilemmaHandler.getDefault());

wsUpdateOp.replace(workspaceConnectionTarget, workspaceConnectionSource);

wsUpdateOp.run(null);

In both scenario I get this exception:

com.ibm.team.filesystem.client.FileSystemException: Failed to accept, there are component(s) affected that are disconnected

I have other components on my Project Area but are not connected to the stream or repository workspaces I'm using.

Any idea on how to use this method?

Thanks,
Michele.
