Hi Francesco
Thanks for your help. There was one small issue with your example, since on
user creation you do not have a usermod on the execution yet. But that was
easily fixed.
I have used the following code and rule in my workflow to get this working.
Might I suggest that we use this in the standard deployment of Syncope? I
think that provisioning via the workflow is functionality that should be
included out of the box. The version I made is parameterized via the
workflow (description of usage is included) so it is not specific to my
project.
import org.activiti.engine.delegate.DelegateExecution;
import org.activiti.engine.delegate.Expression;
import org.apache.syncope.client.mod.UserMod;
import org.apache.syncope.core.persistence.beans.user.SyncopeUser;
import org.apache.syncope.core.propagation.PropagationByResource;
import org.apache.syncope.core.workflow.ActivitiUserWorkflowAdapter;
import org.apache.syncope.core.workflow.WorkflowException;
import org.apache.syncope.core.workflow.activiti.AbstractActivitiDelegate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
/**
* This workflow service task allows to provision a resource to a user from

stringValue="%%YOUR_RESOURCE%%"/>
</extensionElements>

public class ProvisionResources extends AbstractActivitiDelegate {
protected static final Logger LOG =
LoggerFactory.getLogger(ProvisionResources.class);
private Expression resource;
public void setResource(Expression resource) {
this.resource = resource;
}
@Override
protected void doExecute(DelegateExecution execution) throws Exception {
String resourceName = (String) resource.getValue(execution);
if (resourceName == null || resourceName.isEmpty()) {
throw new WorkflowException(new IllegalStateException("Please
specify a resource"));
}
SyncopeUser user = (SyncopeUser)
execution.getVariable(ActivitiUserWorkflowAdapter.SYNCOPE_USER);
UserMod userMod = (UserMod)
execution.getVariable(ActivitiUserWorkflowAdapter.USER_MOD);
if (userMod == null) {
userMod = new UserMod();
}
userMod.addResourceToBeAdded(resourceName);
// update SyncopeUser
PropagationByResource propByRes = dataBinder.update(user, userMod);
// report updated user and propagation by resource as result
execution.setVariable(ActivitiUserWorkflowAdapter.SYNCOPE_USER,
user);
execution.setVariable(ActivitiUserWorkflowAdapter.PROP_BY_RESOURCE,
propByRes);
}
}
