How to implement OnDeleteNodePolicy for deleting user?

jeffreyman — Wed, 09 Dec 2020 09:42:19 GMT

We want to add custom code when deleting user. We have tried to use OnDeleteNodePolicy or BeforeDeleteNodePolicy, but failed.

Here is custom code:

public void beforeDeleteNode(NodeRef nodeRef) {
String username = serviceRegistry.getPersonService().getPerson(nodeRef).getUserName();
UserInfoDao.removeUserInfo(username); //remove user in custom db
}

Here is error message:

Hi @jeffreyman

The error says, " User does not exist and could not be created". Is this a case of calling the code at the wrong time (transaction conflict)? This blog post might help, & then there is also Jeff Pott's tutorial.

HTH,

I think you'd better test if the node is a person node before calling your code

like following

QName nodeTyp = nodeService.getType(nodeRef)
if(ContentModel.TYPE_PERSON.equalsde before calling ){
//your code
}
