Hi All,
I have written a sample java action-demo to explore how tailf:cli-completion-actionpoint ( Tail-f YANG CLI extensions) works.
However when i invoke the completion-actionpoint (from CLI) I always get below errors in log files
ncs.log
no registration found for callpoint if-complete-action/completion of type=external
devel.log
<ERR> 1-Dec-2018::21:03:28.952 zahid-VirtualBox ncs[29209]: devel-c no registration found for callpoint if-complete-action/completion of type=external
<ERR> 1-Dec-2018::21:03:28.952 zahid-VirtualBox ncs[29209]: ncs Return error {cs_error,undefined,misc,external,undefined,undefined,
<<"no registration found for callpoint if-complete-action/completion of type=external">>,
undefined,undefined,false}
Here is the yang definition
module action-demo {
..namespace "http://com/example/actiondemo";
..prefix action-demo;
..import ietf-inet-types { prefix inet; }
..import tailf-common { prefix tailf; }
..import tailf-ncs { prefix ncs; }
..description "A small demo module to illustrate how to implement user defined actions";
..container action-demo {
....tailf:action myvpn-action {
......tailf:actionpoint actionpoint-myvpn;
......input {
........container endpoint {
..........tailf:cli-compact-syntax;
..........leaf device {
............type leafref {
..............path "/ncs:devices/ncs:device/ncs:name";
............}
............tailf:info "Endpoint Device";
............mandatory true;
..........}
..........leaf interface {
............tailf:info "Endpoint Port";
............type string;
............tailf:cli-completion-actionpoint if-complete-action;
............mandatory true;
..........}
........}
......}
....}
..}
}
Here is the Java code snippet
public class ActionDemo {
private static Logger LOGGER = Logger.getLogger(ActionDemo.class);
// some code here
// ...
@ActionCallback(callPoint = "if-complete-action", callType = ActionCBType.COMPLETION)
Completion completion(DpActionTrans actx, char cliStyle, String token, char completionChar, ConfObject[] kp, String cmdPath, String cmdParamId,
ConfQname simpleType, String extra) throws DpCallbackException {
try {
LOGGER.info(String.format("completion() callback, actionpoint : %s", actx.getActionPoint()));
CompletionReply reply = Completion.newReply();
reply.addCompletion("fe-0/0", null);
reply.addCompletion("fe-0/1", null);
reply.addCompletion("ge-0/0", null);
reply.addCompletion("ge-0/1", null);
reply.setCompletionInfo("interfaces");
reply.setCompletionDesc("all device interfaces");
return reply;
} catch (Exception e) {
throw new DpCallbackException("completion failed", e);
}
}
}

Any help will be greatly appreciated.
