4 years ago Hi,
Problem can be reproduced for a deviate replace statement, referencing another module as shown by the following two modules::
module ericsson-certm-ext-sgsn-mme {
yang-version 1.1;
namespace "urn:rdns:com:ericsson:oammodel:ericsson-certm-ext-sgsn-mme";
prefix certmxsgsnmme;
import ietf-yang-types {
prefix yang;
}
import ericsson-certm-sgsn-mme {
prefix ecertm;
}
revision "2019-01-24";
deviation /ecertm:certm/ecertm:user-label {
deviate replace {
type yang:date-and-time;
}
}
}
module ericsson-certm-sgsn-mme {
yang-version 1.1;
namespace "urn:rdns:com:ericsson:oammodel:ericsson-certm-sgsn-mme";
prefix ecertm;
revision "2019-08-21";
container certm {
leaf user-label {
type string;
description "Label for free use. An additional descriptive text.";
}
}
}The following test code...
@Test
def void testExposeScopeContextProviderNPE_2() {
copyAll(dir, "ScopingNPETestModels2")
val yangFile1 = new File(dir, "ericsson-certm-ext-sgsn-mme.yang")
val URI yangFileURI = URI.createFileURI(yangFile1.canonicalPath)
val injector = XTextInjector.getInstance()
val xtextResourceSet = injector.getInstance(XtextResourceSet)
val resource = xtextResourceSet.getResource(yangFileURI, true)
val module = resource.contents?.get(0) as AbstractModule
println(module)
EcoreUtil.resolveAll(module)
}throws the exception:
[20-04-27 21:12:55.611] ERROR LazyLinkingResource:getEObject:241 - resolution of uriFragment '|3' failed.

Hi Miro,
We found NullPointerException in our deviation test cases, if we remove deviation statement from test model then test cases work fine. the test model is attached ericsson-certm-mynode-yang.txt
