Quote from documentation for org.opendaylight.controller.md.sal.common.api.data.AsyncDataBroker#registerDataChangeListener: "If there is any preexisting data in data tree on path for which you are registering, you will receive initial data change event, which will contain all preexisting data, marked as created." However DataChangeListener are not being notified of preexisting data on registration when wildcard ID is used Version: Helium-SR4 Sample unit test attached |

Valentin, could you please submit a gerrit with this test? |

Moiz, which project should it go into? |
| Comment by Moiz Raja [ 16/Oct/15 ] |
|
I would like you to push the unit test to the controller code base in the md-sal common project. |

This does not work with the in-memory data store b/c it performs a read of the registered path in order to determine the initial notification event but the data tree does not allow wildcarded reads so no data is returned. This was fixed in CDS by https://git.opendaylight.org/gerrit/#/c/26949/. We'll have to do something similar in the in-memory data store. |

Submitted https://git.opendaylight.org/gerrit/#/c/64734/ for the md-sal project. This fixes the issue for DataTreeChangeListener - DataChangeListener is deprecated and in fact doesn't even exist in the md-sal project. |
