Hi,

I'm trying to redeploy some processes definitions (jbpm4.4). the documentation is not clear about that the code is hidden by calling 

I'm deploying process definition like that :

NewDeployment deployment = repositoryService.createDeployment();
for (Resource resource : resources) {
    logger.debug("deploying {}", resource.getFilename());
    deployment.addResourceFromInputStream(resource.getFilename(), resource.getInputStream());
    Resource imageResource = resourceHelper.getResource(resource.getURL().toString().replace(".jpdl.xml", ".png"));
    logger.trace("image file {}", imageResource.getURL().getPath());
    if (imageResource.exists()) {
       deployment.addResourceFromInputStream(imageResource.getFilename(),
                                                imageResource.getInputStream());
    }
}
try {
    String deploymentId = deployment.deploy();
    logger.info("jbpm deployement done for deployementID {}", deploymentId);
} catch (JbpmException e) {
    logger.warn("processes not deployed", e);
}


It works well for the first deployment...

But of next deployement, it failed with an hibernate NoUniqueResultException :
